EMB3FHAT2R

Overview

The EMB3FHAT2R is a dual digital transistor (bias resistor built-in transistor) manufactured by ROHM Semiconductor. It integrates two PNP transistors with bias resistors in a compact SOT-563-6 surface-mount package. The device supports a maximum collector current of 100 mA and offers a collector-emitter voltage rating of 50 V. Key electrical parameters include a DC current gain (hFE) ranging from 100 to 600, a transition frequency (fT) of 250 MHz, and a power dissipation capacity of 150 mW. It is qualified under AEC-Q101 standards for automotive applications and operates at temperatures up to +150°C.

Feature Summary

• Integrates dual PNP transistors with built-in bias resistors for simplified circuit design
• Qualified for automotive applications under AEC-Q101 standards
• High thermal stability with a maximum operating temperature of +150°C

Applications

• Automotive signal switching circuits
• General-purpose digital logic interfaces
• Biasing networks for amplifier stages

Procurement Notes

Verify the NRND status before procurement, as this component is not recommended for new designs. Confirm that existing inventory meets project timelines. Ensure compatibility with SOT-563-6 footprints during integration planning. Check for alternative sourcing options if long-term supply assurance is required for production runs.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required in a small form factor. The 50 V rating and 100 mA current capability suit low-power switching tasks. Consider the 250 MHz transition frequency for moderate-speed digital applications. Verify that the AEC-Q101 qualification aligns with specific automotive reliability requirements.

Part Context

This part belongs to ROHM's series of pre-biased transistors designed to replace discrete resistor-transistor combinations. It simplifies PCB layout by reducing component count. The SOT-563 package allows for high-density mounting. As a dual unit, it provides matched characteristics for differential or parallel configurations.

Replacement Considerations

Consult official substitution guides for equivalent parts. Verify pinout compatibility and electrical parameter alignment. Ensure the replacement maintains AEC-Q101 qualification if used in automotive contexts.
