2N6988

Overview

The Microchip Technology 2N6988 is a quad PNP silicon switching transistor configured as a dual bipolar junction transistor (BJT) array. It operates with a maximum collector-emitter voltage of 60 V and a continuous collector current of 600 mA. The device dissipates up to 400 mW of power and maintains a low saturation voltage of 1.6 V at specified currents. Designed for surface-mount installation in a 14-FlatPack package, it supports an extended operating temperature range from -65°C to +200°C. The component features a minimum DC current gain of 100 at 150 mA and 10 V, ensuring reliable performance in high-temperature environments.

Feature Summary

• Quad PNP configuration providing four independent switching channels within a single surface-mount package.
• High thermal stability supporting operation up to +200°C junction temperature.
• Low saturation voltage characteristics optimized for efficient switching applications.

Applications

• Military-grade switching circuits requiring MIL-PRF-19500/558 qualification.
• High-temperature electronic systems utilizing surface-mount technology.
• Precision analog switching arrays demanding stable PNP characteristics.

Procurement Notes

Verify the specific ordering suffix to confirm the exact package type and qualification level, as variations exist between standard commercial and military specifications. Confirm RoHS compliance status directly with the manufacturer, as certain variants may not meet modern environmental directives. Ensure the supplier provides valid traceability documentation for aerospace or defense procurement requirements.

Selection Notes

Select this component when a quad PNP array is required for high-temperature environments exceeding standard commercial limits. The 14-FlatPack package suits space-constrained surface-mount designs. Verify that the 60 V collector-emitter rating aligns with the circuit's maximum voltage swings. Consider the 400 mW power dissipation limit relative to the expected thermal management capabilities of the printed circuit board layout.

Part Context

The 2N6988 belongs to a family of multiple PNP silicon switching transistors qualified under MIL-PRF-19500/558. Related devices include the 2N6987 and 2N6987U, which share similar structural configurations but may differ in specific electrical parameters or qualification levels. This series is designed for rugged applications requiring reliable bipolar transistor performance in extreme conditions.

Replacement Considerations

Direct substitutes include the JAN2N6988 and JANS2N6988, which maintain equivalent electrical characteristics and military qualification standards. Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit within the existing assembly.
