UMH25NFHATN

Overview

The UMH25NFHATN is a dual NPN digital transistor from ROHM Semiconductor, housed in a compact SOT-363 (UMT6) surface-mount package. It integrates two pre-biased transistors with internal base and emitter-base resistors, eliminating the need for external components. Key electrical specifications include a collector-emitter voltage of 50V, a continuous collector current of 100mA, and a power dissipation rating of 150mW. The device features a minimum DC current gain of 80 at 10mA and 5V, with a transition frequency of 250MHz. It is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• AEC-Q101 qualified for automotive reliability requirements
• Dual NPN configuration with integrated bias resistors
• Compact SOT-363 surface-mount packaging

Applications

• Automotive logic circuits
• Driver circuits for relays and solenoids
• Gate drive circuits for MOSFETs

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and automotive qualification status. Confirm RoHS compliance and specific tape-and-reel quantities with authorized distributors. Cross-reference datasheet revisions to ensure compatibility with design requirements.

Selection Notes

Select this component when dual NPN switching with built-in biasing is required in space-constrained designs. Ensure the 50V voltage rating and 100mA current capacity meet circuit demands. Consider the 150mW power dissipation limit and thermal management needs for the SOT-363 package.

Part Context

This part belongs to ROHM's UMH series of digital transistors, specifically designed for replacing multiple discrete components. The NFHA suffix typically denotes automotive-grade qualification and specific packaging variants within the standard UMH25 family.

Replacement Considerations

The UMH25NTN is a parameter-equivalent alternative within the same manufacturer's lineup. Verify if automotive qualification is strictly required, as non-NFHA variants may lack AEC-Q101 certification.
