5962-8876906KFC

Overview

The Broadcom Limited 5962-8876906KFC is a high-speed optocoupler featuring four independent channels in a hermetically sealed 16-flatpack package. It operates on a 4.5V to 20V DC supply with a 1500VDC isolation rating and supports data rates up to 5 Mb/s. The device utilizes open collector outputs capable of 15 mA sink current, with forward currents of 8 mA and voltages of 1.3 V. Transition times are specified at 45 ns rise and 10 ns fall, while power dissipation is limited to 200 mW across an operating temperature range of -55°C to +125°C.

Feature Summary

• Hermetically sealed ceramic construction for enhanced environmental protection
• High common-mode transient immunity of 1 kV/µs
• Push-pull output stage configuration for improved signal integrity

Applications

• Military and aerospace avionics systems requiring radiation-hardened reliability
• High-reliability industrial control interfaces
• Harsh environment communication bus isolation

Procurement Notes

Verify the specific suffix KFC against official datasheets to confirm pinout and electrical tolerances. Ensure procurement channels provide traceable documentation for military-grade components. Confirm that the flat-pack 16 package matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when hermetic sealing and high common-mode noise rejection are critical. The push-pull output design offers faster switching than standard open-collector variants. Verify that the 5 Mb/s speed meets system timing constraints and that the 16-pin flat-pack form factor fits the mechanical enclosure.

Part Context

This part belongs to the 5962-88769 series of high-speed optocouplers from Broadcom. It shares functional similarities with other members like the 5962-8876905K2A but differs in channel count and package type. The series is designed for applications demanding superior isolation performance and long-term stability under extreme conditions.

Replacement Considerations

Direct substitutes include other 5962-88769 series parts with matching hermetic packages. Verify equivalent CMTI ratings and transition times when cross-referencing with similar military-grade optocouplers.
