DMMT3904-TP

Overview

The DMMT3904-TP is a dual NPN bipolar junction transistor (BJT) manufactured by Micro Commercial Components. It is housed in a surface-mount SOT-363-6 package and operates with silicon technology. The device supports a maximum DC collector current of 200 mA and withstands a collector-emitter voltage of 40 V, with a collector-base voltage rating of 60 V and an emitter-base voltage of 5 V. Key electrical characteristics include a gain-bandwidth product of 300 MHz, a minimum DC current gain of 40, and a collector-emitter saturation voltage of 300 mV. It functions within a temperature range of -55°C to +150°C.

Feature Summary

• Dual NPN configuration integrating two transistors in a single compact package for space-efficient circuit designs.
• High-speed switching capability supported by a 300 MHz gain-bandwidth product suitable for signal processing applications.

Applications

• General-purpose switching circuits requiring dual NPN logic or amplification stages.
• Signal conditioning and buffering in low-power electronic systems.
• Interface circuits where compact dual-transistor arrays are preferred over discrete components.

Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to procurement, as manufacturing updates may occur. Confirm that the SOT-363-6 package dimensions align with the target PCB footprint. Ensure that the 200 mA current rating and 40 V voltage limits meet the operational requirements of the intended application without exceeding thermal dissipation constraints.

Selection Notes

Select this component when a dual NPN topology is required in a small surface-mount form factor. Compare against single-transistor alternatives like the MMBT3904-TP if only one channel is needed, or higher-power variants if current demands exceed 200 mA. Verify that the 5 V emitter-base voltage rating is sufficient for the driving signals used in the design.

Part Context

This part belongs to the MCC BJT family, specifically designed as a dual-array alternative to standard single transistors. It shares core electrical specifications with the MMBT3904 series but offers integrated dual-channel functionality. The SOT-363-6 package provides a compact solution for modern electronics assembly compared to through-hole options.
