EMB53T2R

Overview

The EMB53T2R is a dual digital transistor manufactured by ROHM Semiconductor, featuring two PNP transistors with built-in bias resistors. It is housed in an SOT-563-6 (EMT6) surface-mount package. The device supports a collector-emitter voltage of -50V and a continuous collector current of -30mA per element. Key electrical parameters include a minimum DC current gain (hFE) of 60 at -5mA and -10V, a maximum operating frequency of 250MHz, and a power dissipation rating of 150mW. The typical input resistance is 47kOhms with a resistor ratio of 1. The component operates within a temperature range up to +150°C.

Feature Summary

• Integrates dual PNP transistors with pre-bias resistors to simplify circuit design.
• Utilizes the compact SOT-563-6 package for efficient space utilization.
• Provides high-speed switching capabilities suitable for digital logic applications.

Applications

• Digital logic interface circuits
• Switching applications in consumer electronics
• General-purpose signal amplification

Procurement Notes

Verify the specific suffix 'T2R' confirms the tape-and-reel packaging format when ordering. Confirm RoHS compliance status through the official datasheet or manufacturer certification documents prior to integration. Ensure the supplier provides traceable documentation matching the ROHM Semiconductor part number to avoid counterfeit components.

Selection Notes

Select this component for designs requiring dual PNP switching with integrated base resistors. Compare the 47kOhm input resistance against other variants like EMB51T2R if different biasing levels are required. Verify that the -50V voltage rating meets the system's operational requirements.

Part Context

The EMB53T2R belongs to ROHM's EMB series of dual digital transistors. This series is designed to replace multiple discrete components, reducing board space and assembly costs. It shares the EMT6 package form factor with other models in the family, such as EMB51T2R and EMB52T2R, differing primarily in internal resistor values and transistor polarity.

Replacement Considerations

Direct pin-compatible substitutes within the same series include EMB51T2R (NPN/NPN configuration) and EMB52T2R (PNP/PNP configuration). When substituting, verify that the input resistance values and current gains match the original circuit design requirements.
