UMD9NHE3-TP

Overview

The UMD9NHE3-TP is a dual digital transistor from Micro Commercial Components, featuring integrated NPN and PNP configurations within a compact SOT-363-6 surface-mount package. It operates with a collector-emitter voltage of 50V for the NPN section and -6V for the PNP section, alongside a 40V rating. The device includes typical input resistors of 10 kOhms with a resistance ratio of 4.7. Key electrical specifications include a minimum DC current gain (hfe) of 68 at 5 mA and 5 V, continuous collector current of 70 mA, and peak current of 100 mA. Power dissipation is rated at 200 mW, with an output voltage of 300 mV and a maximum operating temperature of +150 C.

Feature Summary

• Integrates both NPN and PNP digital transistors in a single dual configuration for space-efficient circuit design.
• Includes built-in input resistors to simplify biasing networks and reduce external component count.
• Qualified for automotive applications under AEC-Q101 standards to ensure reliability in demanding environments.

Applications

• Automotive electronic systems requiring qualified dual-transistor solutions.
• General-purpose switching circuits utilizing pre-biased NPN/PNP pairs.
• Logic interface applications where resistor integration simplifies board layout.

Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity against the manufacturer's latest datasheet before procurement. Confirm that the AEC-Q101 qualification status aligns with your project's automotive reliability requirements. Ensure the SOT-363-6 footprint matches your PCB design constraints. Cross-reference the part number with official distributor catalogs to confirm current availability and authenticity.

Selection Notes

Select this component when a combined NPN and PNP digital transistor is required in a minimal footprint. The 10 kOhm input resistance suits standard logic levels. Consider the 70 mA continuous current limit for load driving capabilities. Verify thermal management needs given the 200 mW power dissipation rating in the small SOT-363-6 package. Ensure the 50V voltage rating meets the circuit's operational demands.

Part Context

This part belongs to the UMD9N series of dual digital transistors manufactured by Micro Commercial Components. It represents a specialized discrete solution combining two distinct transistor polarities into one package. The series targets applications needing compact, pre-biased switching elements. The HE3 designation typically indicates specific manufacturing process or environmental compliance features within the MCC portfolio.

Replacement Considerations

Direct pin-compatible replacements must match the SOT-363-6 package and dual NPN/PNP configuration. Verify equivalent voltage ratings (50V/40V) and current limits (70mA). Check if alternative manufacturers offer AEC-Q101 qualified parts with similar 10 kOhm input resistance ratios. Ensure thermal characteristics and hfe gains are comparable for direct substitution.
