Broadcom Phototransistor Optocoupler, 1 Channel, SOIC-4, 50mA

The Broadcom Phototransistor Optocoupler features mini-flat surface-mount device (SMD) construction, incorporating a light-emitting diode optically coupled to a phototransistor. This design provides reliable electrical isolation while allowing signal transmission between circuits.

A key advantage of this component is its small dimension, which allows for significant space saving on printed circuit boards. It offers a current transfer ratio (CTR) of 50% minimum at an input forward current (IF) of 5mA and a collector-emitter voltage (VCE) of 5V, with a specified minimum CTR of 130%. Additionally, the device boasts a high collector-emitter voltage (VCEO) of 80V and a robust isolation voltage of 3.75kV, ensuring safe operation in isolated circuit environments.

Handling Precautions

Please note that this is an ESD sensitive device. Proper precautions must be taken while handling the component to prevent damage from electrostatic discharge.

Applications

This optocoupler is highly versatile and suitable for a wide range of applications. It is commonly used in computers, computer peripherals, test and measurement equipment, consumer electronics, and signal processing systems.
