LH1539AAC, LH1539AACTR, LH1539AB Vishay Semiconductors 1 Form A Photo Darlington Telecom Switch FEATURES DIP 1 • Solid state relay and autopolarity optocoupler in one 8-pin package 8 • Isolation test voltage 5300 VRMS • Surface mountable 7 2 • Optocoupler 3 - Bidirectional current detection 6 - High CTR: 300 % SMD 4 5 • Solid state relay - Form A LH1525 type i179055-1 - Low operating current - Typical RON 25 i179034_2 - Load voltage 400 V DESCRIPTION - Load current 120 mA The LH1539 telecom switch consists of an optically isolated solid state relay (SSR) form A and a bidirectional input optocoupler in a single 8-pin package. The SSR is ideal for switch hook and dial-pulse switching while the optocoupler performs ring detect and loop current sensing functions. Both the SSR and optocoupler provide 5300 VRMS of input-to-output isolation voltage. The SSR is integrated on a monolithic receptor die using smart power technology. The SSR features low On resistance, high breakdown voltage, and current-limit circuitry that protects the relay from telephone line induced lightning surges. The optocoupler provides bidirectional current sensing via two anti parallel GaAs infrared emitting diodes. Very high current transfer ratio (CTR) is achieved by coupling to a photodarlington transistor. This high CTR allows the user to minimize the size of the ring detector capacitor. - Current limit protection - Linear, AC/DC operation - Clean bounce free switching - Low power consumption • Compliant to RoHS Directive 2002/95/EC and in accordance to WEEE 2002/96/EC APPLICATIONS • General telecom switching - On/off hook switching - Dial pulse - Ring current detection - Loop current sensing AGENCY APPROVALS file no.
