8102802PA

Overview

The Broadcom Limited 8102802PA is a dual-channel, hermetically sealed logic output optocoupler designed for high-speed digital isolation. It features an open collector output with Schottky clamping to minimize storage time and enhance switching speed. The device supports a data rate of 10 MBd and provides 1500 VDC isolation voltage. It operates within a temperature range of -55 °C to 125 °C and utilizes a PDIP-8 package. Key electrical parameters include a forward current of 20 mA, response times in the nanosecond range, and a common mode transient immunity of 1 kV/µs.

Feature Summary

• Hermetically sealed construction ensures reliability in harsh environments and full military temperature operation.
• Schottky-clamped open collector outputs reduce storage time for improved high-speed performance.
• Dual-channel configuration provides independent signal isolation within a single package.

Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Industrial control systems operating in high-noise environments
• Military and aerospace electronic systems demanding hermetic sealing

Procurement Notes

Verify that the specific order suffix corresponds to the required packaging and qualification level. Confirm compliance with MIL-PRF-38534 Class H requirements if applicable. Ensure the procurement channel provides valid traceability documentation for hermetically sealed components. Check for availability of qualified distributors authorized to supply this specific part number.

Selection Notes

Select this component when dual-channel isolation with high-speed logic output is required. The hermetic seal makes it suitable for applications where standard plastic packages are insufficient. Consider the open collector output type for interfacing with various logic families. Evaluate the 10 MBd data rate against system timing requirements before finalizing the design.

Part Context

This part belongs to the 81028 series of high-speed, high-CMR logic gate optocouplers. These devices are engineered for mission-critical applications requiring robust signal integrity. The series includes single, dual, and quad channel variants with hermetic sealing options. They are designed to operate over the full military temperature range while maintaining high reliability standards.

Replacement Considerations

Direct replacements may include other hermetically sealed dual-channel optocouplers from the same manufacturer family, such as the 8102802PC or 8102802PB, provided they meet the same pinout and electrical specifications. Verify that any substitute maintains the required hermetic seal and MIL-PRF-38534 compliance if mandated by the application.
