Quadrac
Internally Triggered Triacs (4 A to 15 A)

General Description
Teccor’s
Quadrac
devices are triacs that include a diac trigger
mounted inside the same package. This device, developed by
Teccor, saves the user the expense and assembly time of buying
a discrete diac and assembling in conjunction with a gated triac.
Also, the alternistor
Quadrac
device (QxxxxLTH) eliminates the
need for a snubber network.
The
Quadrac
device is a bidirectional AC switch and is gate con-
trolled for either polarity of main terminal voltage. Its primary pur-
pose is for AC switching and phase control applications such as
speed controls, temperature modulation controls, and lighting
controls where noise immunity is required.
Triac current capacities range from 4 A to 15 A with voltage
ranges from 200 V to 600 V.
Quadrac
devices are available in the
TO-220 package.
The TO-220 package is electrically isolated to 2500 V rms from
the leads to mounting surface. 4000 V rms is available on special
order. This means that no external isolation is required, thus
eliminating the need for separate insulators and insulator-mount-
ing steps and saving dollars over “hot tab” devices.
All Teccor triac and diac chips have glass-passivated junctions to
ensure long-term device reliability and parameter stability.
Variations of devices in this data sheet are available for custom
design applications. Consult the factory for more information.
