HSSR-711E

Overview

The HSSR-711E is a high-reliability, Class E single-channel hermetically sealed power MOSFET optocoupler manufactured by Broadcom Limited. It features an 8-pin DIP ceramic package with gold-plated leads, designed for robust isolation applications. The device provides 1500VDC voltage isolation between input and output channels. It accepts DC input signals and delivers an output current of 1.6A per channel. Key timing parameters include a maximum propagation delay of 6ms for low-to-high transitions (tpLH) and 0.25ms for high-to-low transitions (tpHL). The component operates within a temperature range of -55°C to +125°C.

Feature Summary

• Hermetically sealed construction in an 8-pin ceramic DIP package ensures environmental stability and long-term reliability.
• High voltage isolation capability of 1500VDC provides safe separation between control and power circuits.
• Class E classification indicates suitability for demanding industrial and aerospace environments requiring strict performance standards.

Applications

• Industrial motor control systems requiring high-voltage isolation
• Aerospace and defense electronic interfaces
• Medical equipment signal isolation

Procurement Notes

Verify the manufacturer part number against official Broadcom documentation to ensure authenticity. Confirm that the ceramic package and gold-plated lead specifications match the required hermetic sealing standards. Check for any specific handling requirements associated with Class E components during assembly. Ensure compatibility with existing PCB footprints for 8-DIP configurations before finalizing procurement orders.

Selection Notes

Select this component when high-reliability hermetic isolation is critical for system integrity. Consider the 1500VDC isolation rating for applications involving significant potential differences. Evaluate the 1.6A output current capacity against load requirements. Verify that the propagation delays align with system timing constraints. Ensure the operating temperature range meets the environmental conditions of the intended deployment site.

Part Context

The HSSR-711E belongs to the HSSR series of power MOSFET optocouplers from Broadcom Limited. This series is characterized by its use of ceramic packaging and gold-plated leads to achieve hermetic sealing. These devices are engineered for high-reliability applications where standard plastic-packaged optocouplers may not suffice due to environmental stress or longevity requirements.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement should only be considered if the exact electrical and mechanical specifications can be matched by another hermetically sealed Class E power MOSFET optocoupler with identical pinout and isolation ratings.
