Product Highlight

  • Contact Form: SPST (1 Form B)
  • Output Voltage: 350 V
  • On-state Resistance-Max: 35 Ω
  • Contact Current-Max: 120 mA
  • Isolation Voltage-RMS: 3750 V
The LCB110STR is a 1-Form-B (normally closed) relay which uses optically coupled MOSFET technology to provide 3750 Vrms of input to output isolation. The efficient MOSFET switches and photovoltaic die use Clare’s patented OptoMOS® architecture.

A highly efficient GaAIAs infrared LED controls the optically coupled output. The LCB110 has low on-resistance and is well suited for most applications requiring a normally closed relay.
