With a minimum current transfer ratio of 20% at 10mA forward current, it guarantees signal transfer across the isolation barrier even with moderate LED drive — useful for logic-level interfaces and status feedback in industrial controls. Switching is rated at 2µs turn-on and 2µs turn-off typical, which suits low-to-mid speed isolation applications like PLC digital inputs, relay drivers, and AC mains zero-cross detectors. ## Through-hole fit for field service and prototyping The 6-DIP (0.300-inch, 7.62mm) body with through-hole pins is breadboard-friendly and can be socketed or soldered — no hot-air station needed, so it is a solid pick for bench bring-up or a field swap where the kit has a soldering iron and a desoldering pump. Operating temperature spans -40°C to 100°C, covering most indoor and outdoor equipment enclosures without derating concerns. Maximum output voltage is 30V, and the phototransistor saturates at 500mV max — the base pin allows external biasing or feedback compensation for tighter switching thresholds.","metaTitle":"onsemi 4N25M Optoisolator, 4170Vrms, 6-DIP, Through Hole","metaDescription":"onsemi 4N25M optocoupler, 4170Vrms isolation, 20% CTR min at 10mA, 2µs switching, -40°C to 100°C, 6-DIP through hole.
