UMX1N-TP

Overview

The UMX1N-TP is a dual NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates two NPN bipolar junction transistors with built-in bias resistors into a single surface-mount package. The device utilizes silicon technology and is designed for high-speed switching applications. Key electrical specifications include a maximum collector current of 100 mA, a power dissipation rating of 150 mW, and a maximum operating temperature of +150°C. The unit weighs approximately 9 mg.

Feature Summary

• Dual NPN configuration with integrated bias resistors
• High-speed switching capability suitable for digital logic interfaces
• Compact surface-mount design for space-constrained PCB layouts

Applications

• Digital signal buffering and level shifting
• Logic gate replacement in microcontroller circuits
• Switching loads in low-power digital systems

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Micro Commercial Components or authorized distributors before integration. Confirm that the SOT-363 package dimensions match your PCB footprint requirements. Ensure thermal management strategies account for the 150 mW power dissipation limit under expected operating conditions to maintain reliability within the specified temperature range.

Selection Notes

Select the UMX1N-TP when a compact solution for dual NPN switching with internal biasing is required. Compare its 100 mA continuous collector current and 250 MHz maximum operating frequency against alternative digital transistors to ensure compatibility with target circuit speeds. Evaluate the 150 mW power dissipation capability relative to the thermal environment of the final assembly to prevent overheating during sustained operation.

Part Context

This component belongs to the UMX1N series of dual digital transistors from Micro Commercial Components. It shares the same functional architecture as other devices in the family but is distinguished by its specific NPN polarity and resistor network configuration. The series is designed to replace discrete resistor-transistor combinations, simplifying schematic design and reducing component count in digital interface applications.

Replacement Considerations
