MSR2N3810U/TR

Overview

The MSR2N3810U/TR is a dual small-signal Bipolar Junction Transistor (BJT) manufactured by Microchip Technology. It integrates two PNP transistors within a single surface-mount package, designed for low-power switching and amplification applications. The component belongs to the 2N3810 series, offering high current gain and reliable performance in compact electronic circuits. As a RoHS-compliant device, it supports environmentally conscious manufacturing processes while maintaining the electrical characteristics required for general-purpose signal processing tasks.

Feature Summary

• Dual configuration integrating two independent PNP transistors in one package
• Surface-mount technology suitable for automated assembly
• High DC current gain for effective signal amplification
• RoHS compliant construction

Applications

• General-purpose signal amplification circuits
• Low-power switching applications
• Audio pre-amplifier stages
• Logic interface circuits

Procurement Notes

Verify the specific suffix and tape-and-reel packaging details with the manufacturer or authorized distributor before ordering. Confirm that the dual BJT configuration meets the design requirements. Ensure compliance with relevant environmental directives. Check for any recent product change notifications that might affect pinout or specifications. Validate availability through official channels as distribution status may vary.

Selection Notes

Select this component when a dual PNP transistor solution is required in a compact surface-mount form factor. Consider the maximum collector current and voltage ratings against the circuit demands. Evaluate the thermal dissipation capabilities if operating near limits. Compare the hFE range with other available options to ensure sufficient gain for the intended application. Verify compatibility with existing PCB footprints and assembly processes.

Part Context

This part is part of the broader 2N3810 family of dual small-signal BJTs produced by Microchip Technology. It shares core electrical characteristics with other variants in the series but differs in packaging and termination style. The U/TR suffix typically indicates a specific surface-mount reel packaging format. It serves as a modern replacement for older through-hole equivalents in contemporary designs requiring space efficiency.

Replacement Considerations

Direct replacements include other dual PNP SMT BJTs from Microchip such as the JAN2N3810U/TR or similar industry-standard parts like the BC857 series, provided pinouts and electrical parameters match. Verify that substitute components meet the same voltage, current, and gain specifications. Ensure the alternative package type fits the existing board layout without modification.
