HSSR-7110

Overview

The HSSR-7110 is a hermetically sealed, single-channel power MOSFET optocoupler manufactured by Broadcom Limited. It features a DC input driving an N-channel MOSFET output capable of handling up to 1.6A continuous current with a typical on-resistance of 1.0 ohm at 90V. The device provides 1500VDC isolation voltage and operates within a temperature range of -55°C to +125°C. Packaged in a DIP-8 through-hole ceramic housing, it exhibits maximum propagation delays of 6ms for turn-on and 0.25ms for turn-off.

Feature Summary

• Hermetically sealed construction using ceramic packaging for enhanced environmental protection
• High current switching capability via integrated N-channel power MOSFET output stage
• Robust electrical isolation between input LED and output MOSFET circuits

Applications

• Industrial motor control systems requiring isolated power switching
• High-voltage AC/DC conversion interfaces
• Solid-state relay replacements in harsh environments

Procurement Notes

Verify the specific suffix (e.g., #300) against the datasheet to confirm lead frame plating or reel specifications. Confirm package type matches DIP-8 requirements. Ensure thermal management aligns with the 125°C maximum operating limit. Check RoHS compliance status as indicated in official documentation before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and significant load current are required in a single package. The hermetic seal makes it suitable for applications where standard plastic packages may fail due to moisture or chemical exposure. Consider the relatively slow turn-on delay if high-frequency PWM switching is necessary.

Part Context

This part belongs to the HSSR series of special purpose isolators from Broadcom. It represents a legacy hermetic technology line distinct from modern surface-mount optocouplers. The series is designed for reliability in aerospace, military, and industrial sectors where long-term stability under extreme conditions is critical.

Replacement Considerations

Direct pin-compatible replacements are limited due to the hermetic ceramic package. Verify if alternative hermetic MOSFET optocouplers from other manufacturers meet the 1.6A current and 1500V isolation requirements without redesigning the PCB footprint.
