JANS2N6987U

Overview

The JANS2N6987U is a multiple (quad) PNP silicon switching transistor manufactured by Microchip Technology. Qualified per MIL-PRF-19500/558, this component belongs to the JANS radiation-hardened series designed for space applications. It features four independent PNP transistors in a single package. Maximum ratings include a collector-emitter voltage of 60V, collector-base voltage of 60V, emitter-base voltage of 5.0V, and a continuous collector current of 600mA. Total power dissipation is rated at 1.5W.

Feature Summary

• Radiation-hardened design qualified for space environments under MIL-PRF-19500/558 standards
• Quad configuration integrating four independent PNP switching transistors
• Silicon planar construction optimized for high reliability

Applications

• Spacecraft logic circuits requiring radiation tolerance
• Satellite switching systems
• Military avionics control interfaces

Procurement Notes

Verify the specific qualification level and lot traceability documentation upon order confirmation. Ensure that the procurement channel provides valid Certificate of Compliance and Material Test Reports consistent with military aerospace requirements. Confirm that the delivered units match the exact JANS suffix designation to guarantee radiation hardness specifications are met for the intended mission profile.

Selection Notes

Select this component when radiation tolerance is critical for space or high-altitude operations. The quad PNP configuration allows for compact circuit designs compared to discrete single transistors. Verify that the 60V collector-emitter voltage and 600mA current ratings align with the system's electrical loads. Consider thermal management strategies given the 1.5W total power dissipation limit in the specified package.

Part Context

This device is part of Microchip's broader portfolio of radiation-hardened bipolar junction transistors. It shares functional similarities with other members of the 2N6987 family but carries the JANS suffix indicating full radiation hardening suitable for unrestricted space use. It serves as a specialized alternative to standard commercial grade transistors in harsh environment electronics.

Replacement Considerations

Direct replacements must maintain the JANS radiation qualification. Equivalent parts from other manufacturers require verification against MIL-PRF-19500/558 standards. Standard commercial 2N6987 variants lack the necessary radiation hardness and are not suitable substitutes for space applications.
