Broadcom SS22-0B00-02: Product Overview and Technical Specifications

The Broadcom SS22-0B00-02 is a high-performance, multi-channel optocoupler designed to provide critical reinforced isolation in demanding industrial and power electronics applications. As a key component in safety-critical systems, it ensures the reliable transmission of signals between high-voltage and low-voltage circuits while preventing dangerous high-voltage transients from damaging sensitive control-side components.

This device integrates two independent isolation channels within a single, compact package (typically an SSO-8 or similar), offering a space-efficient solution for modern, high-density board designs. Each channel features a GaAlAs (Gallium Aluminum Arsenide) infrared LED optically coupled to a high-gain photodetector, ensuring excellent noise immunity and stable performance across a wide temperature range.

A primary application for the SS22-0B00-02 is in gate drive circuits for IGBTs and MOSFETs within motor controls, solar inverters, and industrial power supplies. Its high common-mode transient immunity (CMTI) ensures that the output remains stable even in the presence of extremely fast-switching voltage noise, which is crucial for preventing shoot-through faults in power conversion stages.
