BT134-800D

TRIACs

TRIAC4 A800 VD trigger gradeAC switching

BT134-800D is an 800 V, 4 A TRIAC with a D-grade gate trigger requirement of up to 5 mA in quadrants I–III and 10 mA in quadrant IV.

Best for

  • AC switching of middle- and small-resistance loads
  • Low-current gate-drive TRIAC control

Avoid if

  • The package variant is not confirmed
  • Required load current exceeds 4 A RMS
  • Compliance or lifecycle documentation is mandatory but unavailable

Check before use

  • Confirm package and pinout
  • Design for 800 V VDRM/VRRM rating
  • Provide up to 10 mA gate trigger current for quadrant IV
  • Validate thermal conditions and surge current margin
