5962-8957202KEC

Overview

The Broadcom Limited 5962-8957202KEC is a high-speed optocoupler featuring two channels in a hermetically sealed DIP-16 package. It delivers a data rate of 10 MB/s with an open collector output type. Key electrical parameters include a forward current of 10 mA, forward voltage of 2.2 V, and reverse voltage of 1.1 V. The device exhibits a rise time of 30 ns and a fall time of 24 ns, supporting an output current of 25 mA. Power dissipation is rated at 564 mW, with an insulation voltage of 1500 Vrms.

Feature Summary

• Hermetically sealed construction for reliable performance in demanding environments
• High common-mode transient immunity of 1 kV/µs for noise resilience
• Schottky-clamped output structure to minimize storage time and enhance switching speed

Applications

• Industrial communication interfaces requiring galvanic isolation
• Data acquisition systems needing high-speed signal transmission
• Power supply control circuits with fast response requirements

Procurement Notes

Verify the specific suffix KEC against official datasheets to confirm pinout and electrical characteristics match system requirements. Ensure procurement sources provide valid manufacturer traceability documentation. Confirm that the hermetic seal integrity meets aerospace or military specifications if applicable. Cross-reference the component marking with the official part number to avoid counterfeit substitutions during sourcing.

Selection Notes

Select this component when high-speed digital isolation is required alongside robust environmental sealing. The 10 MB/s data rate suits applications exceeding standard logic isolator capabilities. Consider the open collector output configuration for flexible interfacing with various logic families. Evaluate the 1500 Vrms insulation voltage for safety compliance in high-voltage separation scenarios.

Part Context

This part belongs to the 5962 family of radiation-hardened and high-reliability optocouplers manufactured by Broadcom Limited. The 5962 series is widely recognized for its consistent performance in defense, aerospace, and industrial sectors. The specific model integrates advanced LED technology with photodetectors to ensure precise signal transfer across the isolation barrier while maintaining long-term stability.

Replacement Considerations

Direct substitutes within the same hermetic DIP-16 form factor should be verified for identical pinout and electrical ratings. Compatible alternatives may include other 5962-series variants with matching 10 MB/s speeds and open collector outputs. Ensure any replacement maintains the 1500 Vrms insulation rating and hermetic seal specification to preserve system reliability.
