8102801EA

Overview

The Broadcom Limited 8102801EA is a high-speed, dual-channel optocoupler housed in a hermetically sealed PDIP-16 package. It features open collector outputs with Schottky clamping for enhanced switching performance. The device supports a data rate of 10 MBd and provides an isolation voltage of 1500 Vrms. Key electrical parameters include a forward current of 20 mA, output current of 25 mA, and power dissipation of 200 mW. Propagation delays are typically 90 ns rise and 40 ns fall times, with a maximum propagation delay of 100 ns. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Hermetically sealed construction ensures reliability in harsh environments
• Schottky-clamped open collector outputs improve switching speed
• High common-mode transient immunity of 1 kV/µs
• Dual-channel configuration for isolated signal transmission

Applications

• Industrial communication interfaces requiring galvanic isolation
• Microprocessor system isolation for noise immunity
• Power supply feedback loops in high-voltage circuits
• Signal isolation in medical equipment

Procurement Notes

Verify the suffix 'EA' confirms the specific PDIP-16 hermetic variant. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure the supplier provides original component traceability. Check for lot date codes relevant to storage life requirements. Validate that the packaging matches the specified through-hole DIP format.

Selection Notes

Select this component when high-speed digital isolation is required alongside robust environmental sealing. The 10 MBd rate suits standard serial protocols. Consider the 1500 Vrms isolation barrier for safety-critical applications. The open collector output requires appropriate pull-up resistors. Verify thermal management capabilities given the 200 mW power dissipation limit.

Part Context

This part belongs to the Broadcom 81028 series of high-speed optocouplers. It is manufactured by Broadcom Limited, formerly Avago Technologies. The series is known for combining speed with hermetic sealing options. It serves as a bridge between low-voltage logic and high-voltage domains.

Replacement Considerations

Direct substitutes must match the 16-DIP hermetic package and 10 MBd speed. Verify equivalent isolation voltage and channel count. Check for compatible output types and pinout configurations.
