The minimum current transfer ratio of 20% at 10 mA forward current means that with 10 mA through the LED, the output transistor can sink at least 2 mA. This is sufficient to drive a logic gate input or a small relay coil, but for higher loads you will need an external transistor or Darlington pair. Output Vce saturation is 500 mV max — low enough to pull a 5 V logic line to a solid low state without extra level shifting. Typical turn-on and turn-off times of 2 µs each make this optocoupler suitable for switching frequencies up to about 100 kHz, covering most digital isolation and PWM signal applications. The 6-DIP (0.400-inch row spacing) through-hole package is breadboard-friendly and easy to hand-solder — a good fit for prototyping or low-volume production. The base pin (pin 6) is brought out, allowing external bias or feedback for linear operation if needed. The Bulk packaging means parts ship as individual tubes or trays, not tape-and-reel — fine for bench work but not pick-and-place without a tube feeder.","metaTitle":"onsemi 4N25TVM Optocoupler, 1-Ch, 4170Vrms, DIP-6","metaDescription":"onsemi 4N25TVM single-channel phototransistor optocoupler, 4170Vrms isolation, 20% CTR min, DIP-6 through-hole.
