MMDT3904S-TPQ2

Overview

The MMDT3904S-TPQ2 is a dual NPN bipolar junction transistor manufactured by Micro Commercial Components. It integrates two independent NPN transistors within a single SOT-363S surface-mount package, designed for low-power amplification and switching applications. The device features a maximum collector current of 200 mA and a collector-emitter voltage rating of 40 V. Key electrical specifications include a collector-base voltage of 60 V, an emitter-base voltage of 6 V, and a power dissipation capacity of 200 mW. The component operates reliably across a temperature range from -55°C to +150°C.

Feature Summary

• Dual configuration integrating two independent NPN transistors in a compact SOT-363S package
• Designed for low-power amplification and general-purpose switching tasks
• Utilizes epitaxial planar die construction for stable performance

Applications

• Low-power signal amplification circuits
• General-purpose switching applications
• Portable electronic devices requiring space-saving dual transistor solutions

Procurement Notes

Verify the specific suffix 'Q2' against official MCC documentation to confirm if it denotes a specific quality tier, tape-and-reel specification, or regional variant distinct from the standard MMDT3904S-TP. Ensure the ordering information matches the required packaging format and compliance standards before procurement.

Selection Notes

Select this component when a dual NPN configuration is required in a small surface-mount footprint. It serves as a direct replacement for other MMDT3904 variants with compatible pinouts. Verify that the 200 mA current limit and 200 mW power dissipation meet the circuit's thermal and load requirements.

Part Context

This part belongs to the MMDT series of dual NPN transistors from Micro Commercial Components. It shares core electrical characteristics with the standard MMDT3904 but utilizes the SOT-363S package variant. The series is widely used in consumer electronics and industrial control boards where space efficiency and dual-transistor functionality are prioritized.

Replacement Considerations

Compatible substitutes include MMDT3904-7-F (Diodes Inc.) and MMDT3904DW (Panjit). Verify pinout compatibility and package dimensions (SOT-363 vs SOT-363S) before substitution.
