Description
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. Teccor offers the complete voltage range (95-330) over three different packages: • • • • TO-92 (95-280 volts) Axial lead DO-15X (95-280 volts) Surface Mount DO-214AA (95-280 volts) TO-202AB (190-330 volts) Applications • • • • • • • • • High voltage lamp ignitors Natural gas ignitors Gas oil ignitors High voltage power supplies Xenon ignitors Over voltage protector Pulse generators Fluorescent lighting ignitors HID lighting ignitors Teccor’s Sidacs feature glass passivated junctions to ensure a rugged and dependable device capable of withstanding harsh environments. Variations of devices covered in this data sheet are available for custom design applications. Please consult the factory for more information.

Storage temperature range (TS) is -65°C to +150°C. The case (TC) or lead (TL) temperature is measured as shown on the dimensional outline drawings. See “Package Dimensions” section of this catalog. Junction temperature range (TJ) is -40°C to +125°C. Lead solder temperature is a maximum of +230°C for 10 seconds maximum; ≥ 1/16" (1.59mm) from case. Electrical Specification Notes (1) (2) (3) (4) (5) (6) (7) See Figure 9.6 for VBO change vs junction temperature. See Figure 9.7 for IBO vs junction temperature. See Figure 9.2 for IH vs case temperature. See Figure 9.14 for test circuit. See Figure 9.1 for more than one full cycle rating. RθJA for TO-202 Type 23 and Type 41 is 70°C/watt. TC ≤ 90°C for TO-92 Sidac and TC ≤ 105°C for TO-202 Sidacs. TL ≤ 100°C for DO-15X and TL ≤ 90°C for DO-214AA. (8) See Figure 9.15 for clarification of Sidac operation. (9) For best Sidac operation, the load impedance should be near or less than switching resistance. (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. • • SIDAC 9-2 Teccor Electronics (972) 580-7777 SIDAC IH Dynamic Holding Current 50/60Hz Sine Wave R = 100Ω (3) (4) VTM Peak On-State Voltage IT = 1 Amp ITSM Peak One Cycle Surge Current 50/60Hz Sine Wave (Non-Repetitive) (5) RS Switching Resistance R (V –V ) BO S = ------------------------------(I – I ) S BO dVq/dt dv/dt di/dt Critical Rate-of-Rise of On-State Current S Critical Critical Rate-of-Rise Rate-of-Rise of Turn-off of Off-State Voltage at Voltage at 8kHz Rated VDRM TJ ≤ 100°C mAmps TYP 60 60 60 60 60 60 60 60 60 60 60 60 MAX 150 150 150 150 150 150 150 150 150 150 150 150 E 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 Volts Max Package G 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 3.0 3.0 3.0 3.0 3.0 3.0 F S 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 50/60Hz Sine Wave (9) Amps 60Hz 20 20 20 20 20 20 20 20 20 20 20 20 50Hz 16.7 16.7 16.7 16.7 16.7 16.7 16.7 16.7 16.7 16.7 16.7 16.7 kΩ MIN 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 0.1 2.0 0.1 0.1 Volts/µSec MIN 20 20 20 20 20 20 20 20 20 42 20 20 Volts/µSec MIN 1500 1500 1500 1500 1500 1500 1500 1500 1500 1500 1500 1500 Amps/µSec TYP 150 150 150 150 150 150 150 150 150 150 150 150 100 Peak Surge (Non-Repetitive) On-State Current [I(TSM)] - Amps 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 4.0 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. 2.0 1.0 1.0 10 100 1000 Surge Current Duration - Full Cycles V-I Characteristics Figure 9.1 Peak Surge Current vs Surge Current Duration THERMAL RESISTANCE (STEADY STATE) RθJC [RθJA] °C/W (TYPICAL) E 35 [95] G 18 [75] F (6) 7 [45] S 30 [85] Teccor Electronics (972) 580-7777 9-3 SIDAC Electrical Specifications Maximum Allowable Ambient Temperature (TA) - ˚C 140 CURRENT WAVEFORM: Sinusoidal - 60 Hz LOAD: Resistive or Inductive FREE AIR RATING 2.0 120 IH IH(TC=25 C) 1.5 ˚ 100 1.0 80 Ratio of 60 .5 TO 40 -9 TO 2 -2 an 02 TO TY PE 23 -2 02 d TY DO PE -2 14 & 1 41 0 -40 -15 +25 +65 +105 +125 25 20 0 0.2 0.4 0.6 0.8 1.0 Case Temperature (TC) - C ˚ 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 +4 H.V.
