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 cur-
rent is interrupted or drops below the minimum holding current of
the device.
Teccor offers the complete voltage range (95-330) over three dif-
ferent 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.
Variations of devices covered in this data sheet are available for
custom design applications. Please consult the factory for more
information.

General Notes
All measurements are made at 60Hz with a resistive load at an
ambient temperature of +25C unless otherwise specified.
Storage temperature range (T
S
) is -65C to +150C.
The case (T
C
) or lead (T
L
) temperature is measured as shown on
the dimensional outline drawings. See "Package Dimensions" sec-
tion of this catalog.
Junction temperature range (T
J
) is -40C to +125C.
Lead solder temperature is a maximum of +230C for 10 seconds
maximum;
1/16" (1.59mm) from case.

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
good commutation at higher switching frequencies as required in ignitor
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, HQI-
T150W, and HQI-T250W which require a minimum of three pulses
at 4kV magnitude and >1
s duration each at a minimum repetition
rate of 3.3kHz.
