1N6702US/TR

Overview

The Microchip Technology 1N6702US/TR is a bidirectional transient voltage suppressor (TVS) diode designed for surface-mount applications. It features voidless hermetically sealed construction in a SQ-MELF package, ensuring high reliability for critical systems. The device provides a peak pulse current rating of 258A under an 8/20µs waveform and offers a maximum clamping voltage of 19V. With a working reverse voltage of 13V and a breakdown voltage minimum of 14.4V, it protects sensitive electronics from electrostatic discharge and transient events across a wide operating temperature range.

Feature Summary

• Bidirectional transient voltage suppression capability for AC or bipolar signal lines
• Voidless hermetically sealed glass construction for enhanced environmental resistance
• High peak pulse current handling with low clamping voltage characteristics

Applications

• Protection of data bus lines in communication equipment
• Electrostatic discharge (ESD) protection for I/O ports
• Surge protection in automotive electronic control units

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when sourcing. Confirm the bidirectional variant matches circuit requirements, as unidirectional versions exist within the same series. Ensure MIL-PRF-19500 qualification levels align with project specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring robust ESD and surge protection in space-constrained designs. The SQ-MELF package allows for compact board layouts while maintaining high thermal performance. Verify that the 13V working voltage exceeds the maximum continuous operating voltage of the protected circuit to prevent unnecessary activation during normal operation.

Part Context

This part belongs to Microchip's family of voidless hermetically sealed TVS diodes. These components are qualified per MIL-PRF-19500 standards, offering superior reliability compared to standard commercial equivalents. The series is engineered for high-reliability environments where failure is not an option, utilizing advanced glass passivation techniques.

Replacement Considerations

Direct replacements include other MIL-PRF-19500 qualified bidirectional TVS diodes in SQ-MELF packages. Verify equivalent peak pulse current ratings and clamping voltages to ensure compatibility. Cross-reference with similar series parts from the manufacturer to confirm pinout and mechanical footprint alignment.
