EMB4T2R

Overview

The EMB4T2R is a dual PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-563-6 surface-mount package. It features a typical input resistance of 10 kOhms and supports a maximum operating frequency of 250 MHz. The device handles a continuous collector current of -100 mA with a collector-emitter voltage (VCEO) rating of -50 V. Power dissipation is rated at 150 mW, and the unit operates within a temperature range up to +150°C. The DC collector/base gain (hFE) minimum is specified as 100 at -1 mA and -5 V.

Feature Summary

• Integrates two PNP transistors into a single compact SMD component for space-efficient circuit design.
• Includes built-in internal resistors to simplify biasing networks and reduce external component count.
• Engineered for high-speed switching applications with a maximum operating frequency of 250 MHz.

Applications

• General-purpose signal switching and logic level translation circuits
• Driver stages for low-power loads in consumer electronics
• Interface circuits requiring compact dual-transistor configurations

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status directly with the supplier or through certified datasheets prior to procurement. Ensure that the requested quantity aligns with standard reel sizes if bulk purchasing is required.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing resistors is required in a small footprint. The 10 kOhm input resistance suits standard logic interfaces. Verify that the -50 V voltage rating and -100 mA current capacity meet the specific load requirements of the target application circuit.

Part Context

This part belongs to the EMB4 series of dual digital transistors from ROHM Semiconductor. These components are designed to replace multiple discrete transistors and resistors, simplifying PCB layout. The EMB4T2R specifically utilizes the SOT-563-6 package, which is common for compact surface-mount designs in modern electronic devices.

Replacement Considerations

Direct pin-compatible substitutes may include other dual PNP digital transistors in SOT-563 packages with similar electrical characteristics. Verify input resistance values and voltage ratings carefully before substitution. Cross-reference with ROHM's official replacement guide for confirmed equivalent parts.
