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

  • TRIAC, 16A, 800V

  • Thyristor/Triac type : Triac

  • Voltage, Vdrm : 800V

  • Current, It rms : 16A

  • Current, Gate Trigger, Igt, (Q1), t2+g+ : 35mA

  • Current, Itsm (50Hz) :155A

  • Current, Itsm (60Hz) :170A

  • Package/Case :TO-220AB
