5962-8957001YC

Overview

The Broadcom Limited 5962-8957001YC is a high-speed, hermetically sealed logic output optocoupler designed for robust signal isolation. It features a single channel with a data rate of 40 Mbps and a common-mode transient immunity of 500 V/µs. The device utilizes an open collector output type and operates with a forward current of 10 mA. Key electrical parameters include a forward voltage of 1.35 V, reverse voltage of 3 V, and output current capability of 25 mA. Power dissipation is rated at 200 mW, with rise and fall times of 15 ns and 10 ns respectively. The unit provides 1500 VDC isolation and is available in an SOIC-8 surface mount package.

Feature Summary

• Hermetically sealed construction ensures reliability in harsh environments
• High-speed operation supports data rates up to 40 Mbps
• Open collector output configuration provides flexible interfacing options
• Strong common-mode transient immunity protects against noise interference

Applications

• Industrial communication systems requiring galvanic isolation
• Data acquisition circuits needing high-speed signal transfer
• Microcontroller interface applications with noise-sensitive environments

Procurement Notes

Verify the specific suffix and package variant when ordering to ensure compatibility with existing board layouts. Confirm that the hermetic seal integrity meets project requirements for environmental exposure. Check RoHS compliance status if restricted substances are prohibited in the assembly process. Ensure proper handling procedures are followed due to the sensitive nature of optical components within the sealed package.

Selection Notes

Choose this component when high-speed digital isolation is required alongside strict environmental sealing standards. The open collector output allows for easy integration with various logic families. Consider the 40 Mbps speed limit when designing for higher bandwidth applications. Evaluate the 1500 VDC isolation rating against system voltage requirements to ensure adequate safety margins.

Part Context

This part belongs to the family of high-speed optocouplers manufactured by Broadcom Limited. It shares functional similarities with other models in the series but is distinguished by its specific hermetic packaging and surface mount form factor. The designation indicates a military-grade or high-reliability variant often used in critical infrastructure where standard plastic packages may not suffice.

Replacement Considerations

Direct substitutes may include other hermetically sealed high-speed optocouplers from the same manufacturer family. Verify pinout compatibility and electrical specifications before swapping. Alternative non-hermetic versions may require re-evaluation of environmental protection strategies.
