The onsemi HMHA281R4V is a single-channel optoisolator featuring a transistor output. It provides an isolation voltage of 3750Vrms, making it suitable for applications requiring robust electrical isolation. The device operates with a DC input and delivers an output current of up to 50mA. Key specifications include a forward voltage (Vf) of 1.3V (typ.) and a Vce saturation of 400mV (max.). The current transfer ratio (CTR) ranges from a minimum of 50% at 5mA to a maximum of 600% at 5mA. Rise and fall times are typically 3µs. This optoisolator is housed in a 4-SMD package, specifically a 4-Mini-Flat (4-SOIC, 4.40mm width), and is supplied on tape and reel. It is designed for surface mounting and operates across a temperature range of -55°C to 100°C. Applications include power supplies, industrial controls, and telecommunications equipment.
