4 pin mini flat SMD phototransistor optocoupler Broadcom HCPL 181 00AE with UL CSA and IEC approvals
Product Overview
The Broadcom HCPL-181 is a phototransistor optocoupler housed in a compact 4-pin mini-flat SMD package with a 2.0-mm profile, offering significant space savings compared to conventional DIP types. It features a light-emitting diode optically coupled to a phototransistor, providing an input-output isolation voltage of 3750 Vrms. With a typical response time of 4 s and a minimum Current Transfer Ratio (CTR) of 50% at 5 mA input current, this optocoupler is suitable for I/O interfaces in computers, system appliances, measuring instruments, signal transmission between circuits of different potentials and impedances, and feedback circuits in power supplies.
