UMB2NFHATN

Overview

The UMB2NFHATN is a dual pre-biased NPN transistor array manufactured by ROHM Semiconductor, housed in a compact SMD UMT6 (SOT-363) package. It integrates two independent NPN transistors with built-in bias resistors to simplify circuit design and reduce component count. Key electrical specifications include a maximum collector current of 100 mA, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. The device features a low saturation voltage of 300 mV at specific test conditions and meets AEC-Q101 automotive qualification standards for reliability.

Feature Summary

• Dual NPN configuration with integrated base and emitter bias resistors
• Automotive-grade reliability certified under AEC-Q101 standards
• Compact surface-mount packaging designed for space-constrained applications

Applications

• Automotive electronic control units and sensor interfaces
• General-purpose switching circuits in consumer electronics
• Logic level translation and buffer stages in embedded systems

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and tape-and-reel specifications. Confirm that the procurement channel provides traceability documentation required for automotive-grade components. Check for RoHS compliance status and ensure storage conditions align with moisture sensitivity levels specified in the datasheet prior to assembly.

Selection Notes

Select this component when a dual NPN solution with fixed biasing is required to minimize board space. Ensure the application voltage does not exceed the 100 V collector-emitter rating. Consider the 150 mW power dissipation limit and thermal management requirements for high-density layouts. Verify that the 47 kOhm input resistance values match the driving source impedance requirements.

Part Context

This component belongs to the UMB series of complex transistors from ROHM Semiconductor, specifically designed for automotive and industrial applications. The UMT6 package offers a small footprint suitable for modern surface-mount technology processes. It serves as a direct replacement for discrete resistor-transistor networks, simplifying assembly and improving signal integrity in digital logic circuits.

Replacement Considerations

Direct substitutes include other dual NPN pre-biased transistors in SOT-363 packages such as the DTC144E or equivalent parts from other manufacturers. Verify pin compatibility and electrical parameters like hFE and VCE(sat) before substitution. Ensure the alternative part also meets AEC-Q101 if used in automotive contexts.
