DMMT5551-TP

Overview

The DMMT5551-TP is a dual NPN plastic-encapsulate transistor manufactured by Micro Commercial Components (MCC). It features a surface-mount SOT-363 package with a continuous collector current of 0.2 A and power dissipation of 0.2 W. Key electrical parameters include a collector-emitter breakdown voltage of 160 V, collector-base breakdown voltage of 180 V, and emitter-base breakdown voltage of 6.0 V. The device 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
• High voltage capability suitable for medium power amplification and switching applications
• RoHS compliant construction with UL 94V-0 flammability rating

Applications

• Medium power amplification circuits
• General purpose switching applications
• Low noise signal processing stages

Procurement Notes

Verify the specific ordering suffix against official MCC documentation before procurement. Confirm that the -TP suffix corresponds to the Tape & Reel packing format containing 3,000 pieces per reel as specified in the manufacturer's ordering information. Ensure compatibility with standard surface mount assembly processes.

Selection Notes

Select this component when a matched pair of NPN transistors is required in a small footprint. The 160V collector-emitter voltage rating supports high-voltage switching tasks. Verify thermal management requirements for the 0.2W power dissipation limit under intended operating conditions.

Part Context

This part belongs to the DMMT5551 series of dual NPN transistors produced by Micro Commercial Components. It serves as a surface-mount alternative to larger through-hole packages while maintaining similar electrical characteristics for dual-channel applications.

Replacement Considerations

Cross-reference with other manufacturers' dual NPN transistors in the SOT-363 package. Verify pinout compatibility and ensure equivalent breakdown voltages and current ratings are met for direct substitution.
