Broadcom DC Input Surface Mount Optocoupler, 12-Pin SO-12, 1 Channel, Max Forward Voltage 1.55V, ACFL-3161-500E

Broadcom ACFL-3161-500E is a high-performance DC input optocoupler designed for industrial and commercial electronics applications requiring electrical isolation and fast switching. It features a compact surface mount SO-12 package with 12 pins, making it suitable for space-constrained printed circuit boards.

This optocoupler integrates a single channel for signal input with a maximum forward voltage of 1.55V and can handle input currents up to 230mA. It supports switching speeds with typical rise and fall times of 7 microseconds, enabling its use in high-frequency PWM control and signal isolation.

Operating across a wide industrial temperature range from -40°C to 125°C, the device is ideal for demanding environments. It offers excellent electrical isolation with an isolation voltage rating of 5kV RMS, enhancing noise immunity and protecting downstream circuits.

The device provides a rail-to-rail output with a high peak output driving current of 10A, making it suitable for directly driving Silicon Carbide (SiC) MOSFETs and Insulated Gate Bipolar Transistors (IGBTs). It ensures fast propagation delay with a maximum of 95 nanoseconds and tight dead time distortion of 35 nanoseconds, crucial for efficient power switching and motor control in industrial applications.

The ACFL-3161-500E requires an operating supply voltage (VDD) between 15V and 30V and includes an Under Voltage Lock Out (UVLO) protection with hysteresis to maintain reliable performance. Its low supply current (maximum 4 mA) enables efficient usage in bootstrap half-bridge topologies.

Compliant with RoHS environmental standards, this optocoupler is manufactured in the Philippines with strict quality controls ensuring reliability. Compact surface mount SO-12 package with 12 pins. Single channel optocoupler with high isolation voltage of 5kV RMS.
