DO-15X Axial Lead DO-214AA Surface Mount TO-202AB Type 1 TO-92 Type 70 Do not use mounting tab or center lead, electrically connected SIDAC (95 - 330 Volts) 9 General Description The Sidac is a silicon bilateral voltage triggered switch with greater power-handling capabilities than standard diacs. Upon application of a voltage exceeding the Sidac breakover voltage point, the Sidac switches on through a negative resistance region to a low on-state voltage. Conduction will continue until the current is interrupted or drops below the minimum holding current of the device.

(10) Teccor's new, improved series of sidacs is designed to ensure goodcommutationathigherswitchingfrequencies asrequiredinignitor circuits for high intensity discharge (HID) lighting. A typical circuit for a metal halide lamp ignitor is shown in the schematic, Figure 9.3. With proper component selection this circuit will produce three pulses for ignition of Osram lamp types such as HQI-T70W, HQIT150W, and HQI-T250W which require a minimum of three pulses at 4kV magnitude and >1µs duration each at a minimum repetition rate of 3.3kHz. 9-2 Teccor Electronics (972) 580-7777 SIDAC IH VTM ITSM RS Dynamic Holding Current 50/60Hz Sine Wave R = 100Ω (3) (4) Peak On-State Voltage IT = 1 Amp Peak One Cycle Surge Current 50/60Hz Sine Wave (Non-Repetitive) (5) Switching Resistance (V –V ) BO S = -------------------------------(I – I ) S BO di/dt Critical Critical Rate-of-Rise Rate-of-Rise of Turn-off of Off-State Voltage at Voltage at 8kHz Rated VDRM TJ ≤ 100°C Critical Rate-of-Rise of On-State Current Amps kΩ Volts/µSec Volts/µSec Amps/µSec MIN MIN MIN TYP 16.7 0.1 20 1500 150 20 20 16.7 16.7 0.1 0.1 20 20 1500 1500 150 150 1.5 20 16.7 0.1 20 1500 150 1.5 20 16.7 0.1 20 1500 150 3.0 1.5 1.5 20 20 16.7 16.7 0.1 0.1 20 20 1500 1500 150 150 1.5 3.0 1.5 20 16.7 0.1 20 1500 150 1.5 3.0 1.5 20 16.7 0.1 20 1500 150 1.5 3.0 3.0 1.5 20 20 16.7 16.7 2.0 0.1 42 20 1500 1500 150 150 20 16.7 0.1 20 1500 150 F 60Hz TYP MAX E G 60 150 1.5 1.5 1.5 20 60 60 150 150 1.5 1.5 1.5 1.5 1.5 1.5 60 150 1.5 1.5 60 150 1.5 1.5 60 60 150 150 1.5 1.5 1.5 1.5 60 150 1.5 60 150 1.5 60 60 150 150 60 150 1.5 S dv/dt 50/60Hz Sine Wave (9) Volts Max Package mAmps R dVq/dt 3.0 50Hz S Peak Surge (Non-Repetitive) On-State Current [I(TSM)] - Amps 100 SUPPLY FREQUENCY: 60 Hz Sinusoidal LOAD: Resistive RMS ON-STATE CURRENT: IT RMS Maximum Rated Value at Specified Junction Temperature 40 20 10 8.0 6.0 BLOCKING CAPABILITY MAY BE LOST DURING AND IMMEDIATELY FOLLOWING SURGE CURRENT INTERVAL OVERLOAD MAY NOT BE REPEATED UNTIL JUNCTION TEMPERATURE HAS RETURNED TO STEADY-STATE RATED VALUE. 4.0 2.0 1.0 1.0 10 100 1000 Surge Current Duration - Full Cycles Figure 9.1 V-I Characteristics Peak Surge Current vs Surge Current Duration THERMAL RESISTANCE (STEADY STATE) RθJC [RθJA] °C/W (TYPICAL) E G F (6) S 35 [95] 18 [75] 7 [45] 30 [85] Teccor Electronics (972) 580-7777 9-3 SIDAC Maximum Allowable Ambient Temperature (TA) - ˚C Electrical Specifications 1.5 Ratio of ˚ IH IH(TC=25 C) 2.0 1.0 .5 0 -40 -15 +25 +65 +105 +125 140 CURRENT WAVEFORM: Sinusoidal - 60 Hz LOAD: Resistive or Inductive FREE AIR RATING 120 100 80 60 TO TO -9 2 02 d 40 TO -2 an -2 02 TY PE DO -2 23 14 TY PE & 1 41 25 20 ˚ Case Temperature (TC) - C 0 0.2 0.4 0.6 0.8 1.0 RMS On-State Current [IT(RMS)] - Amps Figure 9.2 Normalized DC Holding Current vs Case/Lead Temperature Figure 9.5 Maximum Allowable Ambient Temperature vs On-State Current Percentage of VBO Change - % +4 H.V.
