JAN2N2919U

Overview

The JAN2N2919U is a dual small-signal bipolar junction transistor (BJT) manufactured by Microchip Technology. It consists of two NPN transistors integrated into a single surface-mount package, designed for general-purpose switching and amplification applications. The device operates with a maximum collector-emitter voltage of 60V and a continuous collector current of 30mA. Thermal performance is rated at a total power dissipation of 350mW. Constructed using silicon technology, this component is qualified under the JAN military grade standard, ensuring reliability in demanding environments.

Feature Summary

• Dual configuration integrating two NPN transistors within a compact surface-mount footprint
• Qualified to JAN military specifications for enhanced environmental and operational reliability
• Silicon-based construction optimized for general-purpose signal processing tasks

Applications

• General-purpose signal amplification circuits
• Electronic switching applications requiring dual transistor logic
• Military and aerospace electronic systems requiring JAN-qualified components

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as variations exist between reel and tube configurations. Confirm the specific JAN qualification level required for the application, as commercial equivalents may lack the necessary environmental testing. Ensure the supplier provides traceability documentation consistent with military procurement standards.

Selection Notes

Select this component when a dual NPN configuration is required in a space-constrained surface-mount design. Evaluate the 60V breakdown voltage and 30mA current limits against circuit requirements to ensure adequate headroom. Consider the thermal constraints imposed by the 350mW power dissipation rating during high-duty-cycle operations.

Part Context

This part belongs to the 2N2919 family of dual small-signal BJTs. The JAN prefix indicates it meets the strict quality and screening standards defined by MIL-PRF-19500, distinguishing it from commercial variants like the standard 2N2919 which may not offer the same level of radiation hardness or temperature stability.
