RClamp3331ZA Ultra Small RailClamp® 1-Line, 3.3V ESD Protection PROTECTION PRODUCTS - RailClamp® Description Features High ESD withstand Voltage: +/-18kV (Contact/Air) RailClamp TVS diodes are ultra low capacitance devices designed to protect sensitive electronics from damage or latch-up due to ESD, EFT, and EOS. They are designed for use on high speed ports in applications such as cell phones, notebook computers, and other portable electronics. These devices offer desirable characteristics for board level protection including fast response time, low operating and clamping voltage, and no device degradation. RClamp®3331ZA features extremely good ESD protection characteristics including a low typical dynamic resistance of 0.20 Ohms, low peak ESD clamping voltage, and high ESD withstand voltage (+/-18kV contact per IEC 61000-4-2). Low typical capacitance (0.35pF at VR=0V) allows the RClamp3331ZA to be used in applications operating in excess of 5GHz without appreciable signal attenuation. Each device will protect one high speed data line operating at 3.3 Volts. RClamp3331ZA is in a 2-pin SLP0603P2X3F package measuring 0.6 x 0.3 mm with a nominal height of 0.25mm. Leads are finished with lead-free NiAu. The small package gives the designer the flexibility to protect single lines in applications where arrays are not practical. The combination of low peak ESD clamping, low dynamic resistance, and low capacitance makes this device suitable for applications such as USB 3.0, MIPI and V-By-One interfaces in portable devices. ® per IEC 61000-4-2 Able to withstand over 1000 ESD strikes per IEC 61000-4-2 Level 4 1 pack age Ultra-small 020 0201 package Protects one high speed data line Working voltage: +/- 3.3V Low capacitance: 0.35pF typical Extremely low dynamic resistance: 0.20 Ohms (Typ) Low ESD clamping voltage Solid-state silicon-avalanche technology Mechanical Characteristics SLP0603P2X3F Package Pb-Free, Halogen Free, RoHS/WEEE Compliant Nominal Dimensions: 0.6 x 0.3 x 0.25 mm Lead Finish: NiAu Marking: Marking Code Packaging: Tape and Reel Applications Nominal Dimensions USB 2.0 / USB 3.0 MIPI / MDDI V-By-One eDP MHL LVDS Schematic 0.600 0.220 1 0.300 0.160 0.355 BSC 2 0.250 SLP0603P2X3F (Bottom View) Nominal Dimensions (in mm) Revision 3/23/2015 1 www.semtech.com RClamp3331ZA PROTECTION PRODUCTS Absolute Maximum Rating R ating Symbol Value Units Peak Pulse Power (tp = 8/20μs) Pp k 30 Watts Maximum Peak Pulse Current (tp = 8/20μs) Ip p 4 Amps VESD +/- 18 +/- 18 kV TJ -40 to +85 °C TSTG -55 to +150 °C ESD per IEC 61000-4-2 (Air)1 ESD per IEC 61000-4-2 (Contact)1 Operating Temperature Storage Temperature Electrical Characteristics (T=25oC) Parameter Symbol Conditions Reverse Stand-Off Voltage VRWM Pin 1 to 2 or 2 to 1 Breakdown Voltage V BR IBR = 10μA Pin 1 to 2 or 2 to 1 Reverse Leakage Current IR Clamping Voltage Minimum Maximum Units 3.3 V 8 10.5 V VRWM = 3.3V, T=25°C Pin 1 to 2 or 2 to 1 <1 50 nA VC IPP = 1A, tp = 8/20μs Pin 1 to 2 or 2 to 1 3.8 5.5 V Clamping Voltage VC IPP = 4A, tp = 8/20μs Pin 1 to 2 or 2 to 1 5.5 7.5 V ESD Clamping Voltage2 VC IPP = 4A, tlp = 0.2/100ns 4.5 V ESD Clamping Voltage2 VC IPP = 16A, tlp = 0.2/100ns 7 V Dynamic Resistance2, 3 RD tp = 0.2/100ns 0.20 Ohms Junction Capacitance Cj VR = 0V, f = 1MHz 0.35 5.5 Typical 0.45 pF Notes 1)ESD gun return path connected to ESD ground reference plane. 2)Transmission Line Pulse Test (TLP) Settings: tp = 100ns, tr = 0.2ns, ITLP and VTLP averaging window: t1 = 70ns to t2 = 90ns. 3) Dynamic resistance calculated from ITLP = 4A to ITLP = 16A © 2015 Semtech Corporation 2 www.semtech.com RClamp3331ZA PROTECTION PRODUCTS Typical Characteristics Clamping Waveform (tp=1.2/50us) Non-Repetitive Peak Pulse Power vs. Pulse Time 1000 12 TA = 25OC Waveform: tp= 1.2x50us Rs = 2 Ohms 10 Clamping Votlage (V) Peak Pulse Power - PPP (W) TA = 25OC 100 10 8 6 4 2 DR040412-30 0 1 0.1 1 10 -5 100 5 15 Pulse Duration - tp (µs) TLP Characteristic (Positive) 45 5 Transmission Line Pulse Test (TLP) Settings: tp = 100ns, tr = 0.2ns, ITLP and VTLP averaging window: t1 = 70ns to t2 = 90ns 25 0 -5 TLP Current (A) 20 TLP Current (A) 35 TLP Characteristic (Negative) 30 15 10 5 -10 -15 -20 Transmission Line Pulse Test (TLP) Settings: tp = 100ns, tr = 0.2ns, ITLP and VTLP averaging window: t1 = 70ns to t2 = 90ns -25 0 -30 -5 -35 0 2 4 6 8 10 -12 12 -10 -8 Clamping Voltage (V) 70 -4 -2 0 ESD Clamping (-8kV Contact per IEC 61000-4-2) 10 Measured with 50 Ohm scope input impedance, 2GHz bandwidth.
