EMD2FHAT2R

Overview

The EMD2FHAT2R is a complex transistor from Rohm Semiconductor, integrating one NPN and one PNP digital transistor within an SOT-563 (EMT6) surface-mount package. This dual configuration includes built-in resistors to simplify circuit design and reduce component count. The device features a supply voltage of 50V for the NPN element and -50V for the PNP element, with a maximum collector current of 0.1A for both polarities. Input resistance (R1) is specified at 1kΩ, while emitter-base resistance (R2) is 22kΩ. The unit offers a power dissipation rating of 0.15W and operates within a storage temperature range of -55°C to 150°C.

Feature Summary

• Integrates independent NPN and PNP transistor elements in a compact footprint
• Includes built-in input and emitter-base resistors for biasing
• Designed for automated mounting on standard surface-mount equipment

Applications

• Differential amplifier circuits
• High-frequency crystal oscillators
• Starters and switching applications

Procurement Notes

Verify the obsolete status before procurement, as this component is marked as not recommended for new designs. Confirm availability through authorized distributors, noting that stock levels may be limited due to end-of-life status. Ensure the ordering suffix matches the required tape-and-reel packaging specifications for your assembly line.

Selection Notes

Select this part when space constraints require a dual-transistor solution with integrated biasing resistors. It serves as a direct replacement for discrete NPN/PNP pairs in logic interfacing or signal switching roles. Verify that the 1kΩ input resistance aligns with your drive requirements and that the 0.1A current limit suffices for the load.

Part Context

This component belongs to Rohm's series of general-purpose complex transistors designed for high-density PCB layouts. It consolidates two separate transistor functions into a single SOT-563 package, reducing board area and assembly costs compared to using individual discrete components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider equivalent DTR+DTR configurations in SOT-563 packages from other manufacturers if sourcing becomes difficult.
