Component

gate-driver optocouplerIGBT driverMOSFET driver5 kVrms isolationDIP-8L-S12.5 A peak

HT-3120-S1TA1 is an isolated 2.5 A peak IGBT/MOSFET gate-driver optocoupler for 15–30 V output-side supplies, supplied in a DIP-8L-S1 surface-mount lead form.

Best for

  • Isolated IGBT gate-drive stages
  • Isolated MOSFET gate-drive stages
  • Inverters and UPS equipment

Avoid if

  • Output supply is below 15 V or above 30 V
  • A package other than the S1 surface-mount lead form is required
  • Continuous output current near the 2.5 A peak rating is required

Check before use

  • Confirm LED drive current against the 5 mA maximum input threshold specification.
  • Place the specified 0.1 µF bypass capacitor directly between pins 5 and 8.
  • Validate thermal, isolation, creepage, and switching behavior in the final power layout.
