The onsemi H11A5TVM is a single-channel phototransistor optoisolator in a through-hole 6-DIP package (0.400", 10.16mm). It accepts a DC input and provides a transistor-with-base output, making it suitable for logic-level signal isolation in industrial control and power-supply feedback paths. Isolation is rated at 7500Vpk — this is a high-voltage barrier for applications where galvanic separation between high-side and low-side circuits must withstand transient surges above typical 5 kV optocouplers. Minimum current transfer ratio is 30% at 10 mA forward current, and typical turn-on/turn-off times are 2 µs each, which supports switching up to about 250 kHz in digital isolation or gate-drive circuits.
