LH1546ADF

The LH1546ADF is a Solid State Relay with SPST-NO contact and surface-mount terminals. This 1-form-A relay is constructed using a GaAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated BCDMOS technology, is comprised of a photodiode array, switch control circuitry and MOSFET switches. It employs current-limiting circuitry which meets lightning surge testing as per ANSI/TIA-968-B and other regulatory voltage surge requirements when overvoltage protection is provided.

• Current limit protection
• High surge capability
• Clean bounce-free switching
• Low power consumption
• High reliability monolithic detector
• 550mW Power dissipation
• 3ms Turn-on/off maximum time
• -40 to 85°C Ambient temperature range
