Compact phototransistor optocoupler Broadcom HCPL-181-00BE with surface mount design and fast response time
Product Overview
The HCPL-181 is a phototransistor optocoupler featuring a light-emitting diode optically coupled to a phototransistor. Packaged in a 4-pin mini-flat SMD with a 2.0 mm profile, it offers significant space savings with a package volume 30% smaller than conventional DIP types. This device provides high input-output isolation voltage of 3750 Vrms and features a fast response time, typically 4 s. It is suitable for I/O interfaces for computers, system appliances, measuring instruments, signal transmission between circuits of different potentials and impedances, and as a feedback circuit in power supplies. The product is RoHS 6 fully compliant and available with optional IEC/EN/DIN EN 60747-5-2 approvals.
