Broadcom DC Input Optocoupler Surface Mount 12-Pin SO-12 Package ACFL-3161-500E

Broadcom ACFL-3161-500E is a high-performance DC input optocoupler designed for industrial electronics applications requiring high output driving capability and reliability. This device features a rail-to-rail output stage delivering a peak current of 10A, making it ideal for direct driving of silicon carbide (SiC) MOSFETs and insulated gate bipolar transistors (IGBTs) in power conversion and motor drive systems.

The optocoupler is packaged in a compact, surface-mounted SO-12 12-pin package, allowing for effective use of PCB real estate and facilitating automatic insertion processes. It operates over a wide industrial temperature range from -40°C to 125°C, ensuring stable performance in harsh environments. The device includes undervoltage lockout (UVLO) protection with hysteresis to maintain safe operation and prevent malfunction during supply voltage drops.

Featuring fast propagation delay times (95 ns max) and minimal dead time distortion (35 ns max), the ACFL-3161-500E is optimized for high-frequency switching applications commonly found in industrial motor drives, renewable energy inverters, and power supplies. Its low supply current consumption (4 mA max) helps reduce power losses in bootstrap half-bridge topologies.

The device exhibits excellent common mode transient immunity of 100 kV/μs at 1000 V common mode voltage, ensuring robust isolation and noise immunity in electrically noisy environments often encountered in industrial and automotive sectors. It is compliant with RoHS environmental standards, reflecting Broadcom’s commitment to sustainable and safe electronic components.

This surface-mount optocoupler is ideal for applications in industrial automation, motor control, power electronics, and HVAC systems where reliable isolation and high drive current are mandatory. The 12-pin SO package facilitates easy integration into modern compact PCB designs, enhancing production efficiency and component reliability.
