HT8-214-S1TA1

Solid State Relays

dual-channel SSR400 V120 mADIP-8 S1photovoltaic MOSFET5,000 Vrms isolation

HT8-214-S1TA1 is a dual-channel, normally open MOSFET solid-state relay for isolated low-current switching up to 400 V and 120 mA.

Best for

  • Galvanically isolated low-current DC or AC switching
  • Industrial and measurement equipment
  • Dual-channel normally open switching

Avoid if

  • Load current exceeds 120 mA per datasheet rating
  • Low on-state voltage drop is required
  • Lifecycle or supply assurance is mandatory but unverified

Check before use

  • Confirm output polarity and switching topology for the application
  • Calculate load dissipation using on-resistance at operating temperature
  • Use the S1 package pad design and observe isolation layout requirements
