Telecom Switch - 1 Form A Solid State Relay - Vishay SiliconixThe LH1529FP and LH1529GP Telecom switches
consist of an optically coupled Solid State Relay (SSR)
and a bidirectional input Optocoupler The SSR is
ideal for performing Switch hook and dial-pulse
switching while the Optocoupler performs ring detec-
tion and loop current sensing functions. Both the SSR
and opto coupler provide 3000 VRMS of input to output
isolation.
The SSR is integrated on a monolithic receptor die
using high voltage 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 sens-
ing via two anti parallel GaAs Infrared Emitting Diodes
The opto channel provides a minimum CTR of 33 %
at 6.0 mA.
The LH1529FP and LH1529GP come in an 8 pin,
0.080 inch thick plastic flat pak, SMD. By Vishay Intertechnology
