UMB2N-TP

Overview

The UMB2N-TP is a dual digital transistor from Micro Commercial Components, integrating two PNP transistors with built-in biasing resistors into a single SOT-363 (SC-88) surface-mount package. This component provides a collector-emitter voltage of -50V and a continuous collector current of -100mA per channel. It features configurable base input resistances, typically available in values such as 1kΩ, 4.7kΩ, or 47kΩ, alongside emitter-base resistances of similar magnitudes. The device operates within a temperature range of -55°C to +150°C and dissipates up to 150mW of power, making it suitable for compact digital switching applications.

Feature Summary

• Integrates two PNP digital transistors with pre-biased resistors in a compact SOT-363 package
• Supports low-voltage operation with a -50V collector-emitter breakdown rating
• Offers flexible input resistance configurations for various logic interface requirements

Applications

• Differential amplifier circuits requiring matched transistor pairs
• High-frequency crystal oscillator driver stages
• General-purpose digital signal buffering and level shifting

Procurement Notes

Verify the specific suffix variant against the manufacturer's datasheet to confirm exact resistor values, as the base model may denote a family rather than a single fixed configuration. Confirm availability status directly with authorized distributors, as supply levels for this component type can fluctuate. Ensure the ordering code matches the required pinout and resistance combination for your schematic design.

Selection Notes

Select this component when space constraints necessitate a dual-transistor solution in an SC-88 footprint. Ensure the circuit logic polarity aligns with the PNP configuration provided by this part. Verify that the required base resistance values are available within the specific product variant selected, as internal resistor ratios define the switching characteristics.

Part Context

This part belongs to the UMB series of complex transistors manufactured by MCC. These devices are designed to replace discrete resistor-transistor networks, reducing board space and assembly complexity. The UMB2N-TP specifically addresses applications needing dual PNP switching elements with integrated biasing networks.

Replacement Considerations

The UMD2NS-TP serves as a functional substitute within the MCC portfolio, offering identical SOT-363 packaging and dual NPN/PNP configuration. Designers should verify pin compatibility and electrical parameter alignment before swapping components.
