That isolation voltage qualifies it for industrial-grade barrier separation — motor drives, PLC digital inputs, and isolated sensor interfaces where 4 kV class is the minimum. The output is a phototransistor with base access, giving the designer the option to bias the base for faster switching or to use the base as a third terminal for feedback. The 6-SMD gull-wing package is a standard surface-mount footprint; the gull-wing leads provide visual solder-joint inspection and moderate board-level strain relief. ## CTR floor and switching speed Minimum current transfer ratio is 20% at If=10 mA. This means that with 10 mA through the input LED, the output transistor can sink at least 2 mA — enough to drive a logic gate or a low-power relay coil. The typical turn-on and turn-off times are both 5 µs, which suits signal isolation up to about 10 kHz. For faster edges, the base-access pin allows a base-emitter resistor to speed up turn-off. Maximum output voltage is 200V, and continuous output current per channel is 100 mA. The 400 mV Vce saturation at rated current keeps the on-state voltage drop low, minimising power dissipation in the output stage. ## Active production, ROHS3, and ordering options It is ROHS3 compliant, so it meets the current EU restriction levels for lead, mercury, and other substances. Available in Tape & Reel or Cut Tape — the reel option suits automated pick-and-place; cut tape works for prototype or low-volume builds. The closest peer in the same family is the H11AA1SR2M, which accepts both AC and DC input — useful if the input polarity is unknown. The 4N25SR2M offers faster switching (2 µs typical) but a lower 500 mV Vce saturation ceiling.","metaTitle":"H11D3SR2M onsemi Optoisolator – 4170Vrms, DC Input","metaDescription":"onsemi H11D3SR2M single-channel optocoupler: 4170Vrms isolation, 20% min CTR at 10mA, 200V output max, -40°C to 100°C, 6-SMD gull-wing.
