General Description
General purpose switching and phase control applications.
These devices are intended to be interfaced directly to micro-
controllers, logic integrated circuits and other low power gate
trigger circuits such as fan speed and temperature modulation
control, lighting control and static switching relay.
By using an internal ceramic pad, the WTPA series provides
Voltage insulated tab (rated at 2500V RMS)

Note1:
.Although not recommended, off-state voltages up to 800V may be applied without damage, but the TRIAC
may switch to the on-state. The rate of rise of current should not exceed 3A/us.
