EMH3FHAT2R

Overview

The EMH3FHAT2R is a dual NPN digital transistor from ROHM Semiconductor, housed in an SOT-563-6 surface-mount package. It integrates bias resistors for automotive applications and meets AEC-Q101 qualification standards. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 150 mW. The device features a gain-bandwidth product (fT) of 250 MHz, a DC current gain (hFE) ranging from 100 to 600, and a collector-emitter saturation voltage of 300 mV. It operates at temperatures up to +150°C.

Feature Summary

• Dual NPN configuration with built-in bias resistors for simplified circuit design
• Qualified for automotive environments under AEC-Q101 standards
• High thermal stability supporting operation up to +150°C

Applications

• Automotive logic switching circuits
• Driver interface stages requiring integrated biasing
• General-purpose amplification in compact automotive modules

Procurement Notes

Verify the NRND status before integration, as this designation indicates the component is not recommended for new designs. Confirm that existing supply chains can sustain production volumes without interruption. Ensure compatibility with current automotive qualification requirements despite the end-of-life recommendation. Review datasheet revisions for any parameter shifts affecting legacy systems.

Selection Notes

Select this component only if the SOT-563-6 footprint and 50V/100mA ratings align precisely with the design constraints. Consider the NRND status carefully; alternative active parts may offer better long-term availability. Verify that the 150 mW power dissipation and +150°C temperature limit meet the specific thermal management requirements of the target application environment.

Part Context

This part belongs to ROHM's series of dual digital transistors designed for space-constrained automotive electronics. The SOT-563 package allows for high-density mounting on printed circuit boards. As a complex transistor, it replaces multiple discrete components, reducing board space and assembly complexity while maintaining reliable performance in harsh automotive conditions.

Replacement Considerations

Check for direct pin-compatible alternatives within the same ROHM family or other manufacturers offering identical 50V/100mA dual NPN specifications in SOT-563 packages. Ensure any substitute also holds AEC-Q101 certification if required for the specific automotive application.
