UMH11NHE3-TP

Overview

The UMH11NHE3-TP is a dual NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates two NPN transistors with internal biasing resistors in a compact SOT-363 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 50V, a continuous collector current of 50mA, and a power dissipation rating of 150mW. The device features a typical base input resistance of 10 kOhms and an emitter-base resistance ratio of 1. It offers a minimum DC current gain (hFE) of 30 and supports a maximum operating frequency of 250 MHz. The component operates within a temperature range of -55°C to +150°C.

Procurement Notes

Verify the specific ordering suffix HE3 indicates RoHS compliance and halogen-free status as per MCC documentation. Confirm the package type is SOT-363-6 and check for any recent Product Change Notifications (PCNs) regarding assembly sites or materials. Ensure compatibility with standard SMD/SMT reflow soldering profiles specified in the datasheet.

Selection Notes

Select this component when a dual NPN digital transistor with 10k Ohm base resistance is required. Compare hFE minimums and saturation voltages against alternative parts if low-voltage drop is critical. Verify that the 50V VCEO and 50mA Ic ratings exceed the maximum circuit demands. Consider the SOT-363 footprint constraints during PCB layout.

Part Context

The UMH11NHE3-TP belongs to the UMH11N series of pre-biased transistors from Micro Commercial Components. This series consolidates multiple discrete components into a single surface-mount package to reduce board space and assembly costs. The HE3 suffix typically denotes environmental compliance features such as lead-free termination and halogen-free molding compounds.

Replacement Considerations

Potential substitutes include other dual NPN digital transistors in SOT-363 packages with similar 10k Ohm base resistance and 50V ratings. Verify pinout compatibility and electrical parameters such as hFE and Vce(sat) before substitution. Check manufacturer datasheets for equivalent part numbers from other suppliers.
