JAN2N5679

Single Bipolar Transistors Overview

The JAN2N5679 is a single PNP bipolar junction transistor manufactured by Microchip Technology. It utilizes silicon epitaxial planar technology housed in a TO-39 (TO-205AD) metal case. The component supports a collector-emitter voltage of 100 V and a continuous collector current of 1 A. It dissipates up to 1 W of power. Designed for through-hole mounting, it serves as a driver for high-power transistors.

Single Bipolar Transistors Feature Summary

• Single PNP configuration with silicon epitaxial planar construction
• Robust TO-39 metal hermetic package for environmental stability
• Capable of driving high-power transistor stages

Single Bipolar Transistors Applications

Single Bipolar Transistors Procurement Notes

Verify the specific suffix designation to confirm the exact radiation hardness and qualification level required for your application. Ensure the TO-39 lead configuration matches your PCB or chassis layout. Confirm that the manufacturer documentation explicitly lists the JAN2N5679 variant rather than commercial equivalents.

Single Bipolar Transistors Selection Notes

Select this component when a hermetically sealed PNP transistor is necessary for high-reliability environments. The 100 V rating and 1 A current capacity define its operational limits. Consider the thermal resistance of the metal case for heat dissipation requirements in high-power driver topologies.
