EMA6T2R

Overview

The EMA6T2R is a dual digital transistor from ROHM Semiconductor, featuring an emitter common configuration with two PNP transistors. It is housed in a compact SOT-553-5 surface-mount package. The device supports a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. Key electrical characteristics include a minimum DC current gain (hfe) of 80 at -10 mA and -5 V, and a typical input resistance of 4.7 kOhms. It operates within a temperature range of -55°C to +150°C with a power dissipation rating of 150 mW.

Feature Summary

• Integrates two pre-biased PNP transistors in a single emitter-common package for simplified circuit design.
• Provides high-speed switching capabilities suitable for applications requiring fast response times.
• Features integrated base resistors to eliminate external biasing components and reduce board space.

Applications

• General-purpose signal switching in consumer electronics
• Driver circuits for small loads in portable devices
• Logic level translation and interface buffering

Procurement Notes

Verify the specific suffix 'T2R' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the RoHS compliance status aligns with regional regulatory requirements for the target market. Ensure the ordering quantity matches the standard reel size specifications provided by the manufacturer to avoid partial reel handling issues during production.

Selection Notes

Select this component when a dual PNP digital transistor solution is needed to minimize footprint and simplify biasing networks. Consider the -50 V voltage rating and -100 mA current limit to ensure adequate headroom for the intended load conditions. Evaluate the thermal performance relative to the 150 mW power dissipation limit under expected operating temperatures.
