SFH617G-4

Overview

The SFH617G-4 is a single-channel optoisolator featuring an infrared LED and NPN silicon phototransistor. It provides high isolation voltage of 5300Vrms with a peak value of 7500V. The device utilizes a 4-pin dual in-line package (DIP) for through-hole mounting. Key electrical parameters include a maximum forward voltage of 1.65V, maximum input current of 60mA, and typical rise/fall times of 2µs and 14µs respectively. It supports a wide operating temperature range from -55°C to 110°C.
