## **DESCRIPTION** 

The LH1540 is robust, ideal for telecom and ground fault applications. It is an SPST normally open switch (form A) that replaces electromechanical relays in many applications. It is constructed using a GaAIAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated technology, is comprised of a photodiode array, switch control circuitry and MOSFET switches. 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 

- Isolation test voltage 5300 VRMS 

- Typical RON 20  , max. 25  

- 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 

- Compliant to RoHS Directive 2002/95/EC and in accordance to WEEE 2002/96/EC 

## **APPLICATIONS** 

- General telecom switching 

- Instrumentation 

- Industrial controls 

## **Note** 

- See “solid-state relays” (application note 56) 

## **AGENCY APPROVALS** 

UL1577: file no. E52744 system code H, double protection CSA: certification no. 093751 BSI: certification no. 7979/7980 FIMKO: 25419 DIN EN: 60747-5-2 (VDE 0884)/60747-5-5 (pending), available with option 1

## **Notes** 

- Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute maximum ratings for extended periods of the time can adversely affect reliability. 

- (1) Refer to current limit performance application note for a discussion on relay operation during transient currents. 

- (2) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through hole devices (DIP).
