Overview
The HSSR-7112-300 is a hermetically sealed MOSFET output optocoupler manufactured by Broadcom Limited. It features an 8-pin SMD Gull Wing package and operates within a temperature range of -55°C to +125°C. The device provides an isolation voltage of 1500Vrms with a maximum power dissipation of 800mW. Key electrical specifications include a maximum output voltage of 90V, an on-resistance of 1.0 ohm, and an output current per channel of 1.6A. The propagation delay is specified at 250 μs.
Feature Summary
- Hermetically sealed construction for enhanced reliability
- High-speed operation with low propagation delay
- Robust insulation capability for safety isolation
Applications
- Industrial automation control systems
- Power supply feedback loops
- Motor drive circuits
Procurement Notes
Verify the specific suffix '-300' against official Broadcom documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with surface-mount assembly processes given the SMD-8 Gull Wing form factor. Cross-reference isolation ratings and thermal characteristics with system requirements before finalizing procurement decisions.
Selection Notes
Select this component when high isolation voltage and hermetic sealing are required in a compact surface-mount footprint. Consider the 1.6A output current capability and 90V drain-source voltage limits for load matching. Evaluate the 250 μs propagation delay against signal timing constraints in high-speed switching applications.
Part Context
This part belongs to the HSSR series of high-speed solid-state relays from Broadcom. It integrates an infrared LED emitter with a power MOSFET detector in a single package. The series is designed for applications requiring fast switching speeds and high reliability in electrically noisy environments.
Replacement Considerations
Consult official Broadcom substitution guides for direct equivalents. Verify pinout compatibility and electrical parameter margins when considering alternative manufacturers. Ensure replacement parts meet the same hermetic sealing and isolation voltage standards.
