5962-8876801XA

Overview

The Broadcom Limited 5962-8876801XA is a high-reliability, hermetically sealed single-channel logic output optocoupler designed for demanding environments. It operates within a wide supply voltage range of 4.5V to 20V and provides 1500VDC isolation. The device features a tri-state output with a data rate of 5MBd and a common-mode transient immunity of 1kV/µs. Key electrical parameters include a maximum forward current of 8mA, typical rise and fall times of 45ns and 10ns respectively, and a propagation delay of 350ns. It is housed in an 8-DIP gull-wing package and supports operating temperatures from -55°C to 125°C.

Feature Summary

• Hermetically sealed construction ensures reliability in harsh conditions
• Wide supply voltage capability ranging from 4.5V to 20V
• Tri-state output configuration for flexible bus interfacing
• High common-mode transient immunity of 1kV/µs

Applications

• Industrial control systems requiring galvanic isolation
• Military and aerospace electronic circuits
• High-noise industrial environments
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix 'XA' confirms the gold-plated ceramic DIP package and hermetic seal status. Confirm RoHS exemption requirements as this component may not comply with standard restrictions. Validate that the 8-DIP gull-wing form factor matches the target PCB footprint. Ensure the supplier provides traceability documentation suitable for high-reliability applications.

Selection Notes

Select this component when hermetic sealing and wide voltage operation are critical. The tri-state output is suitable for multi-drop communication lines. Verify that the 5MBd speed meets system timing requirements. Consider the thermal management capabilities given the -55°C to 125°C operating range. Ensure compatibility with existing logic families regarding input current and output drive strength.

Part Context

This part belongs to the 5962-88768 series of high-speed, low-input-current logic gate optocouplers. It is a military-grade variant of the HCPL-625x family, distinguished by its hermetic ceramic packaging. The series is designed for applications requiring high reliability and radiation hardness tolerance.

Replacement Considerations

Direct replacements include other hermetically sealed variants from the same series, such as 5962-8876801XX where XX denotes package variations. Non-hermetic equivalents like HCPL-6250 offer similar electrical performance but lack the sealed enclosure. Verify pinout compatibility before substitution.
