8102802YC

Overview

The Broadcom Limited 8102802YC is a high-speed logic output optocoupler featuring two independent channels within a hermetically sealed 8-SMD butt joint package. It provides 1500 Vrms isolation voltage and supports data rates up to 10 MBd. The device utilizes an open collector output configuration with Schottky clamping for enhanced speed performance. Key electrical parameters include a maximum forward current of 20 mA, an output current capability of 25 mA, and a power dissipation rating of 200 mW. It operates reliably across a temperature range from -55 °C to +125 °C, ensuring stability in demanding environments.

Feature Summary

• Hermetically sealed construction ensures reliability under harsh environmental conditions
• High common-mode transient immunity (CMTI) of 1 kV/µs protects against noise interference
• Schottky-clamped outputs provide fast switching speeds suitable for high-data-rate applications

Applications

• Industrial communication bus interfaces requiring galvanic isolation
• Military and aerospace systems operating within full military temperature ranges
• High-reliability digital signal transmission between isolated circuits

Procurement Notes

Verify the specific suffix 'YC' corresponds to the 8-SMD butt joint package variant rather than standard DIP configurations. Confirm that the hermetic seal requirement is met for the intended application environment. Check for RoHS compliance status if lead-free processing is mandated. Ensure the open collector output type aligns with the downstream logic circuit requirements.

Selection Notes

Select this component when both high-speed data transmission and robust environmental sealing are critical. The dual-channel design allows for efficient space utilization in compact layouts. Consider the open collector output topology for flexible voltage level interfacing. Verify that the 1500 Vrms isolation barrier meets the safety standards of the target system architecture.

Part Context

This part belongs to the 81028 series of high-speed, high-CMR logic gate optocouplers manufactured by Broadcom Limited. The series includes various channel counts and package options, all sharing the core technology of hermetic sealing and high-speed performance. This specific model represents the dual-channel SMD variant designed for surface-mount assembly processes.

Replacement Considerations

Direct replacements must match the 8-SMD butt joint package and hermetic seal specification. Compatible alternatives include other parts from the 81028 family or HCPL-563x series with identical pinout and electrical characteristics. Verify that any substitute maintains the 10 MBd data rate and 1500 Vrms isolation rating.
