UMH2NHE3-TP

Overview

The UMH2NHE3-TP is a dual NPN digital transistor manufactured by Micro Commercial Components. It integrates two pre-biased transistors within a single SOT-363 surface-mount package. The device features a typical base input resistance of 47 kOhms with a resistor ratio of 1. Key electrical specifications include a maximum collector-emitter voltage of 50V, a continuous collector current of 100mA, and a power dissipation rating of 150mW. The minimum DC current gain (hFE) is specified as 68 at 5mA and 5V. The component supports a maximum operating frequency of 250MHz and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Dual NPN configuration integrated into a compact SOT-363 package for space-efficient circuit design.
• Pre-biased architecture incorporates internal base resistors to simplify driver interface requirements.
• High-frequency capability supports operation up to 250MHz for signal processing applications.

Applications

• General-purpose switching circuits requiring dual NPN logic control.
• Interface drivers for microcontrollers or logic gates needing level shifting.
• Low-power signal amplification stages in consumer electronics.

Procurement Notes

Verify the specific suffix HE3 against manufacturer documentation to confirm lead-free compliance status. Ensure the ordering quantity aligns with standard reel packaging sizes, typically 3000 units per reel. Confirm that the SOT-363 footprint matches the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a dual NPN configuration is required within a limited board area. The 47kOhm base resistance suits direct interfacing with standard logic outputs. Consider the 150mW power dissipation limit for thermal management in dense assemblies. Verify that the 50V voltage rating exceeds the maximum circuit supply voltage under all operating conditions.

Part Context

This part belongs to the UMH2N series of digital transistors from Micro Commercial Components. It shares the SOT-363 form factor with other dual configurations in the lineup but differs in polarity and internal resistance values. The HE3 suffix indicates a specific manufacturing variant within the broader UMH family, distinguishing it from non-HE3 equivalents like the UMH2N-TP.

Replacement Considerations

Direct substitutes include the UMH2N-TP, which shares identical electrical characteristics and pinout but may differ in environmental compliance. Cross-reference the DTC144EM-TP if a PNP configuration is acceptable, though polarity inversion requires schematic modification. Verify pin compatibility before swapping any alternative dual transistor packages.
