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.

Applications • • • • • • • • •

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)

Teccor’s Sidacs feature glass passivated junctions to ensure a rugged and dependable device capable of withstanding harsh environments.

General Notes

Electrical Specification Notes

•

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.

(1) (2) (3) (4) (5) (6) (7)

•

Lead solder temperature is a maximum of +230°C for 10 seconds maximum; ≥ 1/16" (1.59mm) from case.

See Figure 9.5 for VBO change vs junction temperature. See Figure 9.6 for IBO vs junction temperature. See Figure 9.2 for IH vs case temperature. See Figure 9.13 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. See Figure 9.14 for clarification of Sidac operation. For best Sidac operation, the load impedance should be near or less than switching resistance.

NOTE A: Input pulse width is increased until ICM = 0.63A. NOTE B: Sidac (or Diac or series of Diacs) chosen so that V BO is just below VCEO rating of transistor to be protected. The Sidac (or Diac) eliminates a reverse breakdown of the transistor in inductive switching circuits where otherwise the transistor could be destroyed.
