MMDT3904HE3-TP

Overview

The MMDT3904HE3-TP is a dual NPN epitaxial planar silicon transistor manufactured by Micro Commercial Components (MCC). Packaged in SOT-363, it integrates two independent transistors for low-power amplification and switching. Key electrical ratings include a collector-emitter voltage of 40V, collector-base voltage of 60V, emitter-base voltage of 6V, and continuous collector current of 200mA. The device dissipates up to 200mW with a thermal resistance of 625°C/W. It features a transition frequency of 300MHz, DC current gain ranging from 100 to 300 at 10mA, and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual NPN configuration in a compact SOT-363 surface mount package
• AEC-Q101 qualified for automotive reliability standards
• Halogen-free 'Green' device compliant with RoHS directives
• Epoxy material meets UL 94 V-0 flammability rating

Applications

• Low power amplification circuits
• General purpose switching applications
• Automotive electronic systems requiring AEC-Q101 compliance

Procurement Notes

Verify the specific ordering suffix to confirm packaging format. The '-TP' designation indicates Tape and Reel packaging containing 3000 pieces per reel. Ensure procurement channels are authorized distributors to guarantee genuine parts with full traceability and adherence to MCC quality standards for handling and storage.

Selection Notes

Select this component when space-constrained designs require dual NPN transistors with matched characteristics. The SOT-363 package reduces PCB area compared to discrete components. Verify that the 200mA current limit and 200mW power dissipation meet the circuit requirements under expected ambient temperatures.

Part Context

This part belongs to the MMDT3904 series of dual NPN transistors. It shares core electrical specifications with standard single NPN transistors like the MMBT3904 but offers integrated dual functionality. The HE3 suffix denotes environmental compliance, while TP specifies the tape and reel delivery method.

Replacement Considerations

Direct functional substitutes include other dual NPN transistors in SOT-363 packages such as the DMMT3904 or MMDT3904 variants from different manufacturers. Ensure replacement parts match the 40V VCEO, 200mA IC, and pinout compatibility.
