HT-3021-S1TA1

SCR Output

optotriacnon-zero-cross400 V5000 Vrms isolationS1 package

HT-3021-S1TA1 is a 6-pin, non-zero-cross optotriac driver rated for 400 V repetitive peak off-state voltage and 15 mA maximum LED trigger current.

Best for

  • Isolated AC switching control
  • Motor, solenoid, valve, and temperature-control interfaces

Avoid if

  • The application requires zero-cross turn-on
  • The optotriac must directly carry more than 100 mA RMS

Check before use

  • LED resistor and trigger-current margin
  • AC voltage and dv/dt transient margin
  • S1 PCB footprint and soldering profile
