Product Description
Product Overview
The Broadcom HCPL-181 is a phototransistor optocoupler featuring a light-emitting diode optically coupled to a phototransistor. Packaged in a space-saving 4-pin mini-flat SMD with a 2.0-mm profile, it offers a 30% smaller package volume compared to conventional DIP types. This device provides high input-output isolation voltage of 3750 Vrms and a fast response time, typically 4 s. With a minimum CTR of 50% at 5 mA input current, it is suitable for I/O interfaces, system appliances, signal transmission between circuits of different potentials, and feedback circuits in power supplies.
