EMH52T2R

Overview

The EMH52T2R is a dual digital transistor manufactured by ROHM Semiconductor, featuring two NPN transistors integrated with bias resistors within a compact SOT-563-6 surface-mount package. This component operates with a maximum collector-emitter voltage of 150 mV and supports a continuous collector current of 100 mA. It includes typical input resistors of 47 kOhms with a resistor ratio of 1. The device maintains a minimum DC current gain (hfe) of 100 at 1 mA and 5 V, with a maximum operating frequency of 250 MHz. Power dissipation is rated at 150 mW, and the unit functions reliably up to a maximum operating temperature of +150 C.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors for simplified circuit design
• Utilizes a compact SOT-563-6 surface-mount package for space-constrained applications
• Supports high-frequency operation up to 250 MHz for signal processing tasks

Applications

• Digital switching circuits requiring integrated biasing
• High-frequency signal processing interfaces
• Compact consumer electronics logic control

Procurement Notes

Verify the specific suffix T2R against official ROHM documentation to confirm reel packaging specifications. Ensure compatibility with SOT-563-6 footprint requirements during procurement planning. Cross-reference the manufacturer part number EMH52T2R with authorized distributor catalogs to validate authenticity and traceability before finalizing orders.

Selection Notes

Select this component when a dual NPN configuration with fixed 47 kOhm bias resistors is required. The low saturation voltage and 100 mA current rating suit moderate load switching. Verify that the 150 mV VCEO limit aligns with the target circuit's voltage levels to prevent overstress conditions during operation.

Part Context

This part belongs to ROHM's series of dual digital transistors designed to replace discrete resistor-transistor networks. It consolidates two NPN devices into a single six-terminal package, reducing board space and assembly complexity compared to individual components.

Replacement Considerations

The EMX52T2R is documented as a similar specification replacement with identical polarity and terminal count.
