NP-SBMC Series 80A, Ultra Low Capacitance TSPD The NP−SBMC series of Low Capacitance Thyristor Surge Protection Devices (TSPD) protect sensitive electronic equipment from transient overvoltage conditions. Due to their ultra low off−state capacitance (Co), they offer minimal signal distortion for high speed equipment such as ADSL2+, VDSL and T1/E1 circuits. The low nominal offstate capacitance translates into the extremely low differential capacitance offering superb linearity with applied voltage or frequency. These reliable silicon devices are also a suitable alternative to GDT protectors. The NP−SBMC Series helps designers to comply with the various regulatory standards and recommendations including: GR−1089−CORE, IEC 61000−4−5, ITU K.20/K.21/K.45, IEC 60950, TIA−968−A, FCC Part 68, EN 60950, UL 1950. http://onsemi.com ULTRA LOW CAPACITANCE BIDIRECTIONAL SURFACE MOUNT THYRISTOR 80A, 10x1000ms SURGE Features • • • • • • T Ultra Low − Micro Capacitance Low Leakage (Transparent) High Surge Current Capabilities Precise Turn on Voltages Low Voltage Overshoot These are Pb−Free Devices R SMB JEDEC DO−214AA CASE 403C Typical Applications • xDSL Central Office and Customer Premise • T1/E1 • Other Broadband High Speed Data Transmission Equipment MARKING DIAGRAM ELECTRICAL CHARACTERISTICS VDRM V(BO) CO, 2 V, 1 MHz CO, 50 V, 1 MHz V V pF (Max) pF (Max) NP0640SBMCT3G $58 $77 21 10 NP0720SBMCT3G $65 $88 21 10 NP0900SBMCT3G $75 $98 21 10 NP1100SBMCT3G $90 $130 21 10 NP1300SBMCT3G $120 $160 21 10 NP1500SBMCT3G $140 $180 21 10 NP1800SBMCT3G $170 $220 21 10 NP2100SBMCT3G $180 $240 21 10 NP2300SBMCT3G $190 $260 21 10 NP2600SBMCT3G $220 $300 21 10 NP3100SBMCT3G $275 $350 21 10 NP3500SBMCT3G $320 $400 21 10 Device G in part number indicates RoHS compliance Other protection voltages are available upon request Symmetrical Protection − Values the same in both negative and positive excursions (See V−I Curve on page 3) © Semiconductor Components Industries, LLC, 2008 September, 2008 − Rev. 1 1 AYWW xxxBMG G A Y WW xxx = Assembly Location = Year = Work Week = Specific Device Code (NPxxx0SBMC) G = Pb−Free Package (Note: Microdot may be in either location) ORDERING INFORMATION Device Package Shipping† NPxxx0SBMCT3G SMB (Pb−Free) 2500 /Tape & Reel †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.

Nonrepetitive On−State Current vs. Time (ITSM) Figure 3. Nonrepetitive On−State Impulse vs. Waveform (IPPS) Detailed Operating Description The TSPD or Thyristor Surge Protection Device are specialized silicon based overvoltage protectors, used to protect sensitive electronic circuits from damaging overvoltage transient surges caused by induced lightning and powercross conditions. The TSPD protects by switching to a low on state voltage when the specified protection voltage is exceeded. This is known as a “crowbar” effect. When an overvoltage occurs, the crowbar device changes from a high−impedance to a low−impedance state. This low−impedance state then offers a path to ground, shunting unwanted surges away from the sensitive circuits. This crowbar action defines the TSPD’s two states of functionality: Open Circuit and Short Circuit. Open Circuit – The TSPD must remain transparent during normal circuit operation. The device looks like an open across the two wire line. Short Circuit – When a transient surge fault exceeds the TSPD protection voltage threshold, the devices switches on, and shorts the transient to ground, safely protecting the circuit. + I(OP) + Protected Equipment − V(OP) TSPD − The electrical characteristics of the TSPD help the user to define the protection threshold for the circuit. During the open circuit condition the device must remain transparent; this is defined by the IDRM. The IDRM should be as low as possible. The typical value is less than 5 mA. The circuit operating voltage and protection voltage must be understood and considered during circuit design. The V(BO) is the guaranteed maximum voltage that the protected circuit will see, this is also known as the protection voltage. The VDRM is the guaranteed maximum voltage that will keep the TSPD in its normal open circuit state. The TSPD V(BO) is typically a 20−30% higher than the VDRM. Based on these characteristics it is critical to choose devices which have a VDRM higher than the normal circuit operating voltage, and a V(BO) which is less than the failure threshold of the protected equipment circuit. A low on−state voltage Vt allows the TSPD to conduct large amounts of surge current (500 A) in a small package size. Once a transient surge has passed and the operating voltage and currents have dropped to their normal level the TSPD changes back to its open circuit state. •TSPD looks like an open •Circuit operates normally Normal Circuit Operation I + (Fault) V(Fault) TSPD − + I(Fault) Protected Equipment − Operation during a Fault •Fault voltage greater than Vbo occurs •TSPD shorts fault to ground •After short duration events the O/V switches back to an open condition •Worst case (Fail/Safe) •O/V permanent short •Equipment protected Figure 4. Normal and Fault Conditions http://onsemi.com 5 NP−SBMC Series Transient Surge DEVICE SELECTION Equipment Failure Threshold Off−State Voltage VDRM When selecting a TSPD use the following key selection parameters. Choose a TSPD that has an Off−State Voltage greater than the normal system operating voltage. The protector should not operate under these conditions: Example: Volts TSPD Protection Voltage Upper Limit Normal System Operating Voltage TSPD Transparent TSPD Protection TSPD Transparent (open) (short) (open) Vbat = 48 Vmax Vring = 150 Vrms = 150*1.414 = 212 V peak VDRM should be greater than the peak value of these two components: Time VDRM > 212 + 48 = 260 VDRM Figure 5. Protection During a Transient Surge Breakover Voltage V(BO) TSPD’s are useful in helping designers meet safety and regulatory standards in Telecom equipment including GR−1089−CORE, ITU−K.20, ITU−K.21, ITU−K.45, FCC Part 68, UL1950, and EN 60950. ON Semiconductor offers a full range of these products in the NP series product line. Verify that the TSPD Breakover Voltage is a value less than the peak voltage rating of the circuit it is protecting. Example: Relay breakdown voltage, SLIC maximum voltage, or coupling capacitor maximum rated voltage. Peak Pulse Current Ipps Choose a Peak Pulse current value which will exceed the anticipated surge currents in testing. In some cases the 100 A “C” series device may be needed when little or no series resistance is used. When a series current limiter is used in the circuit a lower current level of “A” or “B” may be used. To determine the peak current divide the maximum surge current by the series resistance. Hold Current (IH) The Hold Current must be greater than the maximum system generated current. If it is not then the TSPD will remain in a shorted condition, even after a transient event has passed.
