Product Overview

The MEL452 is a compact surface-mount optocoupler designed for easy integration into surface-mount assemblies. It features a high-voltage optocoupler constructed with a gallium arsenide infrared light-emitting diode and a Darlington phototransistor with an integrated base-emitter resistor, achieving a collector-emitter voltage (VCEO) exceeding 300V. Key benefits include a high collector-emitter voltage of 300V (Min.), a current transfer ratio of 1000% (Min.), and an input-output isolation voltage of 3750Vrms (min.). This optocoupler is suitable for a wide range of applications including switching power supplies, smart meters, industrial control, measuring instruments, office equipment like copiers, and home appliances such as air conditioners, fans, and water heaters.
