UMB10N-TP

Overview

The UMB10N-TP is a dual pre-biased NPN transistor array manufactured by Micro Commercial Components. It integrates two NPN transistors with built-in biasing resistors into a single surface-mount package, specifically the SOT-363 (also designated as SC-88 or 6-TSSOP). The device features a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Internal resistor values are typically 2.2 kOhms for the base resistor (R1) and 47 kOhms for the emitter-base resistor (R2). With a transition frequency of 250MHz and a power dissipation rating of 150mW, it is designed for compact digital switching applications.

Feature Summary

• Integrates two NPN transistors with integrated biasing resistors to reduce component count and PCB space.
• Utilizes an ultra-small SOT-363 surface-mount package suitable for high-density layouts.
• Provides stable switching performance through fixed internal resistance ratios.

Applications

• Digital signal buffering and level shifting in portable electronics.
• General-purpose switching circuits in consumer appliances.
• Interface drivers for microcontroller output expansion.

Procurement Notes

Verify the specific suffix and marking code against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for any recent production change notices that may affect packaging or material composition. Ensure storage conditions meet specified limits to prevent degradation before soldering.

Selection Notes

Select this component when a dual NPN configuration with fixed biasing is required in a minimal footprint. Compare the internal resistor values against circuit design specifications to ensure proper base drive and leakage characteristics. Consider the thermal limitations imposed by the 150mW power dissipation rating in dense assemblies. Verify that the SOT-363 package dimensions align with the target PCB land pattern.

Part Context

This part belongs to the UMB10 series of pre-biased transistor arrays from Micro Commercial Components. It serves as a complementary counterpart to PNP variants within the same family, offering symmetrical design options for push-pull or differential configurations. The series is characterized by its integration of passive components within the active device package to simplify circuit topology.

Replacement Considerations

Direct pin-compatible substitutes include the Rohm Semiconductor UMB10NTN. Other equivalents may exist from different manufacturers utilizing the SOT-363 package, but verification of internal resistor tolerances and electrical parameters is essential before substitution.
