8102801UC

Overview

The Broadcom Limited 8102801UC is a high-speed optocoupler featuring two independent channels in a hermetically sealed 16-SMD Butt Joint package. It supports data rates up to 10 MBd with an isolation voltage of 1500 Vrms. The device utilizes open collector outputs with Schottky clamping, offering a current transfer ratio of 100% and a propagation delay of approximately 90 ns rise and 40 ns fall times. Operating within a temperature range of -55°C to +125°C, it provides robust electrical isolation for industrial applications.

Feature Summary

• Hermetically sealed construction ensures reliability in harsh environments
• Schottky-clamped open collector outputs enhance switching speed and noise immunity
• High common-mode transient immunity protects against signal integrity issues
• Wide operating temperature range supports extreme industrial conditions

Applications

• Industrial networking systems requiring galvanic isolation
• Power supply feedback loops for voltage level translation
• Solid-state relay driver circuits
• Microcontroller interface isolation in noisy environments

Procurement Notes

Verify the specific suffix 'UC' corresponds to the surface-mount Butt Joint package variant, distinct from the through-hole 'EA' version. Confirm RoHS compliance status via the official datasheet as requirements vary by region. Ensure the ordering quantity matches the manufacturer's standard packaging units to avoid handling discrepancies during assembly.

Selection Notes

Select this component when high-speed digital isolation is required alongside significant voltage differences between circuit domains. The Schottky clamping feature makes it suitable for applications demanding fast turn-off times. Compare CMTI ratings against local noise levels to ensure signal stability. Verify that the open-collector output configuration aligns with the downstream logic input requirements.

Part Context

This part belongs to the Broadcom 81028 series of high-speed optocouplers. The series is designed for demanding industrial and communication applications where signal integrity and isolation are critical. The 81028UC variant specifically addresses surface-mount assembly needs while maintaining the hermetic sealing benefits of the traditional DIP versions.

Replacement Considerations

Direct replacements include the 8102801EA for through-hole applications if board layout permits. Other compatible high-speed optocouplers from different manufacturers may require verification of pinout compatibility and isolation voltage ratings before substitution.
