JAN2N6988

Overview

The JAN2N6988 is a quad PNP silicon switching transistor qualified under MIL-PRF-19500/558. It features a TO-116 package with four independent PNP transistors. Key electrical ratings include a collector-emitter voltage (VCEO) of 60 V, collector-base voltage (VCBO) of 60 V, and emitter-base voltage (VEBO) of 5 V. The maximum DC collector current is 600 mA, with total power dissipation rated at 1.5 W at 25°C ambient temperature. The device operates within a junction temperature range of -65°C to +200°C.

Feature Summary

• Military-grade qualification per MIL-PRF-19500/558 standard
• Quad configuration integrating four independent PNP transistors
• High thermal stability supporting extended operating temperatures up to 200°C

Applications

• Military aerospace switching circuits
• Ruggedized industrial control systems
• High-reliability analog signal processing

Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANS) required for the application, as these levels denote different reliability standards. Confirm that the TO-116 package type matches the board layout constraints. Ensure the supplier provides traceability documentation consistent with military procurement requirements.

Selection Notes

Select this component when a quad PNP array with high voltage tolerance and wide temperature operation is needed. Compare against the 2N6989 if NPN polarity is required instead. Verify that the 600 mA current rating meets the load requirements without exceeding the 1.5 W power dissipation limit under worst-case thermal conditions.

Part Context

The JAN2N6988 belongs to the 2N698 series of multiple PNP silicon switching transistors. This series includes variants such as the 2N6987 and 2N6988U. These devices are designed for high-reliability applications requiring robust performance in harsh environments, distinguishing them from commercial-grade discrete transistors.

Replacement Considerations

The 2N6988U is a surface-mount variant of the same functional device. Direct pin-for-pin replacement is not possible due to the through-hole TO-116 package versus the SMD package of the U suffix. Circuit redesign is necessary for package substitution.
