EMH53T2R

Overview

The EMH53T2R is a dual digital transistor manufactured by ROHM Semiconductor, featuring two NPN transistors integrated into a single SOT-563 (SC-107C) surface-mount package. This component incorporates built-in bias resistors to simplify circuit design and reduce board space. Key electrical specifications include a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA per transistor. The device supports a maximum operating frequency of 250 MHz and has a power dissipation rating of 150mW. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Dual NPN configuration with integrated bias resistors for simplified switching applications
• Compact SOT-563 surface-mount package designed for high-density PCB layouts
• High-speed operation capability up to 250 MHz for efficient signal processing

Applications

• General-purpose digital switching circuits
• Interface drivers between logic gates and loads
• Level shifting in low-voltage digital systems

Procurement Notes

Verify the specific suffix T2R indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact electrical characteristics required for the target application design.

Selection Notes

Select this component for designs requiring matched NPN pairs with fixed biasing in minimal footprint. Compare input resistance values against other variants in the EMH series if specific base drive currents are critical. Verify that the 50V voltage rating exceeds the maximum transient voltages present in the intended operational environment.

Part Context

This part belongs to the ROHM EMH series of complex transistors, which integrate discrete transistors with internal bias networks. These devices replace multiple discrete components, reducing assembly complexity. The EMH53T2R specifically denotes the NPN+NPN polarity variant within this family, distinguished from PNP or complementary types by its internal resistor network configuration.

Replacement Considerations

Direct substitutes may include other ROHM dual NPN digital transistors in SOT-563 packages with similar voltage and current ratings, such as the EMH4T2R or EMH51T2R, provided their specific bias resistor values align with the original circuit requirements.
