HSSR-7112-100

Overview

The HSSR-7112-100 is a power MOSFET output optocoupler manufactured by Broadcom Limited. It features a single channel with a hermetically sealed design and operates within a temperature range of -55°C to +125°C. The device utilizes an 8-SMD butt joint package for surface mount installation. Key electrical specifications include a 90V drain-source voltage rating and a typical on-resistance of 1.0 ohm for the internal MOSFET. It provides high isolation capability, rated at 1500VDC between input and output circuits.

Feature Summary

• Hermetically sealed construction ensures environmental stability and reliability
• High voltage isolation capability for safe signal transmission across potential barriers
• Integrated power MOSFET output stage for direct load driving applications

Applications

• Industrial motor control systems requiring galvanic isolation
• Power supply feedback loops in switching regulators
• Solid-state relay implementations in automation equipment

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm pinout and isolation ratings. Confirm package type compatibility during PCB layout. Check current manufacturing status as production cycles may vary. Ensure thermal management meets operational requirements given the power dissipation characteristics of the integrated MOSFET.

Selection Notes

Select this component when high isolation voltage and low on-resistance are required in a compact surface mount form factor. Consider the DIP-8 equivalent if through-hole mounting is preferred. Evaluate thermal performance under maximum load conditions. Verify that the 90V rating suffices for the intended circuit voltage levels.

Part Context

This part belongs to the HSSR series of MOSFET output optocouplers from Broadcom. The series is designed for applications demanding robust isolation and efficient power switching. The HSSR-7112-100 variant specifically addresses surface mount needs while maintaining the hermetic sealing found in other series members.

Replacement Considerations

Cross-reference with HSSR-7112 for through-hole equivalents. Verify functional compatibility with other 1500VDC isolated power MOSFET optocouplers from different manufacturers before substitution.
