UMH11NFHATN

Overview

The UMH11NFHATN is a dual digital transistor featuring two NPN transistors with built-in bias resistors, manufactured by ROHM Semiconductor. It operates in a surface-mount SOT-363 (UMT6) package with six terminals. Key electrical specifications include a collector-emitter voltage of 50V and a continuous collector current of 100mA. The device has a typical input resistance of 10 kOhms and a DC current gain (hFE) minimum of 30 at 5mA and 5V. It supports a maximum operating frequency of 250MHz with a power dissipation rating of 150mW. The component is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates two NPN transistors with built-in bias resistors to reduce external component count.
• Qualified for automotive applications under the AEC-Q101 standard.
• Designed for high-frequency switching operations up to 250MHz.
• Utilizes a compact SOT-363 surface-mount package for space-constrained designs.

Applications

• Automotive electronic circuits requiring pre-biased switching elements.
• High-frequency signal processing and switching applications.
• General-purpose digital logic interface circuits.

Procurement Notes

Verify the specific suffix 'TN' corresponds to the tape-and-reel packaging format when ordering. Confirm that the AEC-Q101 qualification meets the specific reliability requirements of the target automotive application. Ensure the SOT-363 footprint matches the PCB design guidelines provided in the official datasheet to prevent mounting issues.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required to simplify circuit layout. The 10kOhm input resistance is suitable for standard logic interfaces. Consider the 50V collector-emitter voltage rating to ensure adequate headroom for the intended supply voltage. The 150mW power dissipation limit must be evaluated against thermal constraints in the final assembly.

Part Context

This part belongs to the UMH11 series of complex transistors from ROHM Semiconductor. It serves as an automotive-grade alternative to standard discrete transistor pairs. The 'NFHA' designation indicates specific internal resistor values and packaging characteristics within the broader UMH family. It is functionally comparable to single-transistor equivalents like the DTC114E but offers a dual-channel solution.

Replacement Considerations

The UMH11NTN is a non-automotive grade equivalent within the same series. Single-transistor substitutes such as the DTC114E may require additional external components to replicate the dual-channel functionality. Verify pin compatibility and thermal performance before substituting with other manufacturers' parts.
