SIDAC
(95 - 330 Volts)

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)

General Notes
•
•
•
All measurements are made at 60Hz with a resistive load at an
ambient temperature of +25°C unless otherwise specified.
Storage temperature range (T
S
) is -65°C to +150°C.
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 -40°C to +125°C.
Lead solder temperature is a maximum of +230°C for 10 seconds
maximum;
≥
1/16" (1.59mm) from case.
