BROADCOM ACPL-227 Optocoupler, SOIC-8, 50mA, 3kV

BROADCOM optocoupler with transistor output, featuring two channels in a compact SOIC package. Designed for reliable signal isolation and noise immunity in a variety of electronic applications. This component ensures robust performance with its high isolation voltage and fast response times, making it a versatile choice for designers seeking dependable optoelectronic coupling.

Key features include a minimum current transfer ratio (CTR) of 50% at IF = ±5mA and VCE = 5V, ensuring consistent signal transfer. The high input-output isolation voltage of 3000Vrms provides robust electrical isolation, safeguarding sensitive circuitry. With a typical non-saturated response time of 2µs under specified conditions, this optocoupler is suitable for high-speed switching applications. Its common-mode rejection (CMR) of 10kV/µs (typical) enhances noise immunity, reducing the risk of false triggering in industrial environments.

This device is approved by CSA, UL, and IEC/EN/DIN EN 60747-5-2, ensuring compliance with international safety standards. The forward current (If) is rated at 50mA, and the isolation voltage is 3kV, supporting a broad range of isolation requirements. The collector-emitter voltage (V(br)ceo) is 80V, allowing for use in higher voltage circuits.
