Description

BT139 TRIAC

BT139 is a general purpose Triac normally used for switching and phase control application.

Planar passivated sensitive gate four quadrant triac in a TO-220AB package intended for use in applications requiring high bidirectional transient and blocking voltage capability and high thermal cycling performance. Typical applications include

Motor control
Industrial and domestic lighting,
Heating and static switching

BT139 TRIAC is sensitive gate "series E" triac is intended to be interfaced directly to micro-controllers, logic integrated circuits and other low power gate trigger circuits.

Features of BT139 Triac

Direct triggering from low power drivers and logic ICs
High blocking voltage capability
Planar passivated for voltage ruggedness and reliability
Sensitive gate
Triggering in all four quadrants
