JANS2N6988

Overview

The JANS2N6988 is a quad PNP silicon switching transistor manufactured by Microchip Technology. It is qualified to MIL-PRF-19500/558 for JANS (Space) level reliability. The device features a TO-116 package with four independent PNP transistors. Key electrical ratings include a collector-emitter voltage of 60 V, a collector-base voltage of 60 V, and an emitter-base voltage of 5.0 V. The maximum DC collector current is 600 mA per transistor, with a total power dissipation of 1.5 W at 25°C ambient temperature. The operating junction temperature range spans from -65°C to +200°C.

Feature Summary

• Qualified to MIL-PRF-19500/558 for JANS space-level radiation hardness and reliability
• Contains four independent PNP silicon switching transistors in a single package
• Designed for high-temperature operation up to 200°C junction temperature
• Utilizes TO-116 hermetic ceramic package suitable for harsh environments

Applications

• Military aerospace systems requiring radiation-hardened components
• Satellite onboard electronics and payload control circuits
• High-reliability switching applications in extreme thermal environments

Procurement Notes

Verify the specific procurement channel for JANS qualified devices, as they are distinct from commercial or standard JAN grades. Confirm that the delivered component matches the MIL-PRF-19500/558 specification requirements. Ensure proper handling procedures are followed due to the sensitive nature of space-grade semiconductor materials. Check for any required documentation or traceability records associated with the JANS qualification level.

Selection Notes

Select the JANS2N6988 when radiation tolerance and extended temperature performance are critical. Compare against other JANS quad PNP options if different pinouts or voltage ratings are needed. Consider the TO-116 package constraints for board layout and thermal management. Verify that the 600 mA current rating meets the specific load requirements of the switching application.

Part Context

The JANS2N6988 belongs to the 2N6988 family of multiple PNP silicon switching transistors. It shares the same electrical characteristics as the standard JAN2N6988 but undergoes additional screening and testing to meet the rigorous JANS space qualification standards. This family is designed for high-reliability applications where failure is not an option.

Replacement Considerations

Direct replacements must be JANS qualified versions of the 2N6988 to maintain radiation hardness. Standard JAN2N6988 devices do not offer the same space-level assurance. Verify pinout compatibility with the TO-116 package before substitution.
