HCPL-5431#100

Logic Output Optoisolators Overview

The HCPL-5431#100 is a high-reliability, two-channel hermetically sealed optocoupler manufactured by Broadcom Limited. It features a ceramic dual in-line package (CDIP) with gold-plated leads, designed for Class H applications. The device provides galvanic isolation with a voltage rating of 1500VDC. Key electrical parameters include a data rate of 40 Mb/s, forward current of 10 mA, and output current of 25 mA per channel. Operating temperatures range from -55°C to +125°C, with power dissipation rated at 200 mW.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction in an 8-pin ceramic DIP package with gold-plated leads for high reliability
• Dual-channel design providing independent signal isolation between input and output circuits
• High-speed logic output capability supporting data rates up to 40 Mb/s
• Class H classification suitable for demanding industrial and military environments

Logic Output Optoisolators Applications

• Industrial control systems requiring robust galvanic isolation
• Military and aerospace electronic circuits
• High-reliability data communication interfaces
• Medical equipment with strict safety isolation requirements

Logic Output Optoisolators Procurement Notes

Verify the specific suffix #100 corresponds to the surface mount butt-joint variant when ordering, as standard HCPL-5431 may refer to through-hole packages. Confirm Class H certification requirements are met for your application. Ensure compatibility with 5V logic supply voltages within the specified 4.75V to 5.25V range. Check for RoHS compliance status if required by your manufacturing standards.

Logic Output Optoisolators Selection Notes

Select this component when hermetic sealing and high thermal stability are critical. The 1500VDC isolation voltage supports high-noise environments. Consider the 8-SMD Butt Joint package for surface mount assembly needs. Verify that the 25mA output current meets load requirements. The wide temperature range ensures operation in extreme conditions without performance degradation.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-5431 series of high-speed optocouplers. It is distinct from non-hermetic variants like HCPL-2601 due to its ceramic packaging. The #100 suffix typically denotes the surface mount version, differing from the standard DIP form factor. It serves as a bridge between low-voltage logic and high-voltage isolated domains in critical infrastructure.

Logic Output Optoisolators Replacement Considerations

Direct replacements must match the hermetic ceramic package and Class H rating. Generic plastic-packaged optocouplers lack the required environmental protection. Verify pinout compatibility with the 8-SMD Butt Joint configuration. Ensure equivalent isolation voltage and data speed specifications are maintained for system integrity.
