The MOSFET output stage supports both AC and DC load switching with bounce-free operation, unlike mechanical relays. Optocoupler isolation provides 3750Vrms between input LED and output MOSFET. The low 5mA LED trigger current makes it compatible with direct microcontroller drive. Housed in a compact 4-pin SMD package, it is ideal for telecom, modem, and industrial signal switching.","working_principle":"The LH1500AABTR consists of an infrared LED optically coupled to a photodetector IC that drives a pair of back-to-back MOSFETs. When LED current exceeds the threshold (5mA), the photodetector activates and turns on the MOSFETs, connecting the load terminals. The MOSFET output provides zero-voltage crossing for bounce-free switching. When the LED is off, the MOSFETs present high impedance (off-state), blocking load voltage up to 60V. The 3750Vrms isolation barrier prevents any electrical connection between the control circuit and load.","pin_description":"
