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.

All measurements are made at 60Hz with a resistive load at an
ambient temperature of +25°C unless otherwise specified.
•
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.

IBO
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.

The Sidac (or Diac) eliminates a reverse breakdown of the transistor in inductive switching circuits where otherwise the
transistor could be destroyed.
