DTA015EMT2L

Overview

The DTA015EMT2L is a PNP digital transistor manufactured by ROHM Semiconductor, integrating a single bipolar junction transistor with built-in bias resistors. It operates in the SOT-723 (VMT3) surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device features a typical input resistance of 10 kOhms and a power dissipation rating of 150 mW. It supports a transition frequency up to 250 MHz and functions within an operating temperature range extending to +150 C.

Feature Summary

• Integrates a PNP transistor with thin-film bias resistors for simplified circuit design
• Eliminates external input resistor requirements for inverter configurations
• Provides complete isolation between bias resistors to allow negative input biasing

Applications

• General-purpose switching circuits
• Inverter logic applications
• Driver stages for low-current loads

Procurement Notes

Verify the specific suffix 'T2L' against the manufacturer's official datasheet to confirm the reel packaging configuration and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the ordering code with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for space-constrained designs. The 10 kOhm input resistance suits standard logic interface levels. Consider the -50 V voltage rating and -100 mA current capacity to ensure adequate headroom for the intended load. Verify thermal management capabilities given the 150 mW power dissipation limit in the small SOT-723 package.

Part Context

This part belongs to the DTA015 series of digital transistors from ROHM Semiconductor. It serves as the PNP counterpart to NPN variants like the DTC015 series. The series is designed for general-purpose applications where board space savings and simplified biasing networks are prioritized over high-power handling or automotive-grade qualification.

Replacement Considerations

Direct substitutes may include other PNP digital transistors in SOT-723 packages with similar -50 V / -100 mA ratings and ~10 kOhm input resistance. Verify pinout compatibility and hFE characteristics before substitution. Check if alternative manufacturers offer equivalent performance in the same footprint.
