HTM-3021-TP1

SCR Output

phototriacoptoisolatornon-zero-cross400 V15 mA IFT4-pin SMD

HTM-3021-TP1 is a 400 V random-phase phototriac optocoupler intended to provide isolated triggering for an external AC power triac.

Best for

  • Isolated gate triggering of external AC triacs
  • Random-phase AC control
  • Lighting and temperature-control circuits

Avoid if

  • A zero-cross turn-on function is required
  • The optocoupler output must directly carry the AC load current
  • LED drive cannot reliably provide the required trigger-current margin

Check before use

  • Verify the external triac gate-current requirement in both AC polarities.
  • Design for mains surge immunity and the applicable commutating dv/dt conditions.
  • Verify creepage, clearance, and safety compliance at the final system level.
