UMB18N-TP

Overview

The UMB18N-TP is a pre-biased bipolar junction transistor (BJT) manufactured by Micro Commercial Components. It features an integrated dual PNP configuration housed in a compact SOT-363 surface-mount package. The device is rated for a maximum collector-emitter voltage of 50V and supports a continuous collector current of 100mA. Key electrical specifications include a transition frequency of 200MHz and a total power dissipation capability of 150mW. This component integrates base resistors to simplify circuit design, offering a reliable solution for switching and amplification applications requiring minimal external components.

Feature Summary

• Integrates dual PNP transistors with built-in base biasing resistors within a single package
• Optimized for high-speed switching operations with a 200MHz transition frequency
• Designed for efficient space-constrained layouts using the standard SOT-363 surface-mount footprint

Applications

• General-purpose signal switching circuits
• Logic level translation interfaces
• Driver stages for low-power loads

Procurement Notes

Verify the specific datasheet version from Micro Commercial Components to confirm pinout assignments and thermal characteristics. Ensure that the SOT-363 package dimensions align with your PCB layout constraints. Cross-reference the part number UMB18N-TP with authorized distributors to obtain accurate technical documentation and compliance certificates such as RoHS status before finalizing procurement decisions.

Selection Notes

Select this component when a dual PNP pre-biased configuration is required to reduce board space and assembly complexity. The 50V rating and 100mA current capacity suit low-voltage digital logic applications. Consider the 150mW power dissipation limit for thermal management in dense assemblies. The integrated biasing eliminates the need for external resistors, simplifying schematic design compared to discrete transistor pairs.

Part Context

This part belongs to MCC's line of pre-biased bipolar transistors, which combine active devices with passive resistive elements. The UMB18N-TP specifically addresses the need for compact, dual-channel solutions in consumer electronics and industrial control systems where space efficiency and simplified bill-of-materials are critical design factors.

Replacement Considerations

Consult official manufacturer substitution guides for compatible equivalents. Verify that any alternative maintains the SOT-363 package, 50V voltage rating, and dual PNP pre-biased functionality to ensure mechanical and electrical compatibility without redesign.
