UMH1NHE3-TP

Overview

The UMH1NHE3-TP is a dual NPN pre-biased transistor array manufactured by Micro Commercial Components. It integrates two NPN digital transistors within a single SOT-363 surface-mount package. The device features a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Internal biasing resistors consist of a base resistor (R1) of 22 kΩ and an emitter resistor (R2) of 22 kΩ. Key electrical characteristics include a minimum DC current gain (hFE) of 56 at 5mA and 5V, a saturation voltage of 300mV at 500µA base and 10mA collector current, and a transition frequency of 250MHz. Power dissipation is rated at 150mW with a maximum operating temperature of +150°C.

Feature Summary

• Dual NPN configuration integrated into a compact SOT-363 package for space-efficient circuit design.
• Built-in biasing network simplifies switching applications by eliminating external resistor requirements.
• Qualified to AEC-Q101 automotive standards for enhanced reliability in demanding environments.

Applications

• Automotive electronic control units requiring AEC-Q101 qualified components.
• General-purpose switching circuits in consumer electronics.
• Driver stages for low-power loads in industrial control systems.

Procurement Notes

Verify the specific suffix HE3 against official MCC documentation to confirm lead-free composition and halogen-free status. Confirm that the AEC-Q101 qualification applies to the specific batch or variant intended for automotive use. Cross-reference the SOT-363 pinout with the latest datasheet to ensure compatibility with existing PCB footprints. Validate thermal performance under actual operating conditions given the 150mW power dissipation limit.

Selection Notes

Select this component when a dual NPN switch with integrated biasing is required in a small outline package. The 22kΩ internal resistors suit standard logic interface levels. Ensure the application current remains below 100mA and voltage stays within 50V limits. Consider the 250MHz transition frequency for high-speed switching needs. Verify that the SOT-363 footprint matches the design constraints compared to single-transistor alternatives.

Part Context

This part belongs to the UMH series of pre-biased transistor arrays from Micro Commercial Components. It shares the same physical package and general topology as other variants like UMH1N-TP but includes specific environmental compliance markings indicated by the HE3 suffix. The series is designed to replace discrete resistor-transistor combinations in digital switching applications.

Replacement Considerations

Direct functional substitutes include UMH1N-TP for non-automotive grades. Verify pinout compatibility before replacing with other SOT-363 dual NPN devices from different manufacturers. Check if alternative parts meet the same AEC-Q101 requirements if automotive qualification is mandatory.
