Triacs
Silicon Bidirectional Thyristors
... designed primarily for full-wave ac control applications, such as solid-state relays,
motor controls, heating controls and power supplies; or wherever full-wave silicon
gate controlled solid-state devices are needed. Triac type thyristors switch from a
blocking to a conducting state for either polarity of applied anode voltage with positive
or negative gate triggering.
•Blocking Voltage to 800 Volts
•All Diffused and Glass Passivated Junctions for Greater Parameter Uniformity
and Stability
•Small, Rugged, Thermowatt Construction for Low Thermal Resistance, High Heat
Dissipation and Durability
•Gate Triggering Guaranteed in Three Modes (MAC15FP Series) or Four Modes
(MAC15AFP Series)

1. VDRM for all types can be applied on a continuous basis. Blocking voltages shall not be tested with a constant current source such that the
voltage ratings of the devices are exceeded.
2. The case temperature reference point for all TC measurements is a point on the center lead of the package as close as possible to the plastic
body.

Trigger devices are recommended for gating on Triacs. They provide:
1. Consistent predictable turn-on points.
2. Simplified circuitry.
3. Fast turn-on time for cooler, more efficient and reliable operation.
