5000 Vrms isolation with AC/DC input flexibility
The HCPL3700SVM is a 1-channel optoisolator from onsemi that provides 5000 Vrms galvanic isolation between an AC/DC input and a Darlington output. The AC/DC input type means the LED side accepts either polarity or AC line-level signals without an external rectifier, simplifying the front-end circuit in industrial controls, motor drives, and PLC digital input modules.
Industrial temperature grade and switching response
Turn-on time is 6 µs typical, turn-off 25 µs typical, with a rise time of 45 µs and fall time of 0.5 µs. The Darlington output sinks up to 30 mA per channel at a maximum collector-emitter voltage of 20 V.
onsemi lists the HCPL3700SVM as Active in production and ROHS3 compliant. The base product number is HCPL3700; the 'SVM' suffix denotes the 8-SMD gull wing package in Bulk. Sourced per RFQ against BOM quantity.
