UMH11N-TP

Overview

The UMH11N-TP is a dual NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates two pre-biased NPN transistors within a compact SOT-363 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 50V and a continuous collector current of 50mA. The device features typical base input resistors of 10 kOhms and emitter-base resistors of 10 kOhms, with a DC current gain (hFE) minimum of 30 at 5mA and 5V. It operates with a power dissipation of 150mW and supports a transition frequency up to 250MHz.

Feature Summary

• Integrates two NPN transistors with built-in biasing resistors to simplify circuit design
• Utilizes a small SOT-363 surface-mount package for space-constrained applications
• Provides high-speed switching capabilities suitable for signal processing tasks

Applications

• Signal inversion circuits
• Buffer amplifier stages
• Switching applications in portable devices

Procurement Notes

Verify the specific ordering suffixes such as MSTR, MSCT, or MSDKR when sourcing from distributors like DigiKey, as these indicate different packaging formats including tape and reel, cut tape, or custom reels. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required in a minimal footprint. Ensure the 50V voltage rating and 50mA current capacity align with the target circuit requirements. Consider the 10kOhm resistor values for appropriate base drive characteristics compared to alternative resistance options in the series.

Part Context

This part belongs to the UMH11 series of digital transistors from MCC. It serves as a pre-biased solution replacing discrete transistor and resistor networks. The TP suffix typically denotes a specific manufacturing traceability or environmental compliance standard defined by the manufacturer.

Replacement Considerations

Direct functional equivalents may include parts from other manufacturers offering dual NPN configurations in SOT-363 packages, such as the DTC114E series. Verify pinout compatibility and electrical parameter margins before substitution.
