HT-3021 product

HT-3021

Up to 2 Amps

optotriacnon-zero-cross400 VDIP-65 kVrms isolationexternal triac driver

HT-3021 is a 400 V, non-zero-cross DIP-6 optotriac driver intended to trigger a separate external power triac from isolated low-voltage logic.

Best for

  • Isolated external-triac triggering
  • AC motor and solenoid control
  • Non-zero-cross AC switching

Avoid if

  • A zero-cross optotriac is required
  • The optocoupler must directly carry load current
  • Required trigger current exceeds the available LED drive budget

Check before use

  • 400 V off-state rating versus the intended AC line and surge environment
  • 15 mA maximum trigger-current grade for HT-3021
  • External power-triac gate sensitivity and commutating dV/dt behavior
  • DIP-6 creepage and clearance requirements
