1 Form A Solid-State Relay

DESCRIPTION

The LH1546AEF (4 pin SOP) is robust, ideal for telecom and

ground fault applications. It is an SPST normally open

switch (1 form A) that replaces electromechanical relays in

many applications. It is constructed using a GaAs LED for

actuation control and MOSFETs for the switch output. In

addition, 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.

FEATURES

• Current limit protection

Ω

• Load voltage 350 V

• Load current 120 mA

• High surge capability

• Clean bounce free switching

• Low power consumption

• SMD lead available on tape and reel

• Equivalent to CPC1035N

• Material categorization: For definitions of compliance

APPLICATIONS

• General telecom switching

- On/off hook control
