This document is the SFH615A/SFH6156 optocoupler product manual from Vishay Semiconductors. It features excellent linearity, high reliability, high isolation voltage, etc.
The SFH615A (DIP) and SFH6156 (SMD) optocouplers are designed for signal transmission between electrically isolated circuits. They feature a GaAs infrared diode emitter optically coupled to a silicon planar phototransistor detector and are available in plastic DIP‑4 or SMD packages.
Key features include 5300 VRMS isolation voltage, fast switching times, low coupling capacitance, and a wide CTR range (40‑320 %). The devices are lead‑free, RoHS compliant, and meet UL1577 and IEC 60950 standards. Options provide different CTR grades and package variants, with a 2.54 mm lead spacing and >8.0 mm creepage/clearance.
