Broadcom ACNT H50L 500E optocoupler certified to UL1577 and IEC standards for safe in power electronics
Product Overview
The Broadcom ACNT-H50L is a high-speed, single-channel 1-MBd optocoupler designed for isolated communication logic interfaces and control in high-voltage power systems. Utilizing a Stretched SO8 footprint and advanced insulation technology, it provides robust electrical isolation. The optocoupler features separate connections for the photodiode bias and output transistor collector, significantly increasing speed compared to conventional photo-transistor couplers. With 15-mm creepage/clearance and high-voltage insulation capabilities, it is ideal for applications such as 690VAC drives, renewable energy inverters, and medical equipment, ensuring reliable performance across a wide temperature range and meeting stringent safety standards.
