JANTX2N2919U

Overview

The JANTX2N2919U is a dual small-signal bipolar junction transistor (BJT) manufactured by Microchip Technology. It features an NPN/PNP complementary pair configuration housed in a surface-mount SQ package. The device operates with a maximum collector-emitter voltage of 60V and a continuous collector current of 30mA. Power dissipation is rated at 350mW. Constructed from silicon, this component is designed for general-purpose switching and amplification applications within defined thermal limits.

Feature Summary

• Complementary NPN/PNP dual transistor configuration in a single package
• Surface-mount SQ package design for automated assembly
• Silicon-based construction for reliable signal processing

Applications

• General-purpose signal switching circuits
• Low-power amplification stages
• Digital logic interface buffers

Procurement Notes

Verify the specific suffix U against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives if required by the end application. Confirm that the JANTX grade meets the necessary radiation tolerance or reliability standards for the intended deployment environment before finalizing procurement.

Selection Notes

Select this component when a compact dual BJT solution is required for low-voltage, low-current applications. Compare the 60V rating and 350mW power dissipation against circuit requirements. Consider the SQ package dimensions for PCB layout constraints. Verify thermal management capabilities if operating near maximum ratings.
