Product Overview

The MFODM352 is a compact surface-mount optocoupler designed for easy surface-mount assembly. It integrates an infrared light-emitting diode (LED) made of gallium arsenide with a high-voltage phototransistor featuring an internal base-emitter resistor. This configuration achieves a high collector-emitter voltage (VCEO) exceeding 300V and an input-output isolation voltage of 3750Vrms. The MFODM352 is suitable for applications including switching power supplies, smart meters, industrial control, measurement instruments, office equipment like copiers, and home appliances such as air conditioners, fans, and water heaters.
