DTA014YMT2L

Overview

The DTA014YMT2L is a single PNP pre-biased digital transistor manufactured by ROHM Semiconductor. It integrates internal resistors within an SOT-723 (VMT3) surface-mount package. Key electrical parameters include a collector-emitter breakdown voltage of -50 V and a continuous collector current of 70 mA. The device features a typical input resistance of 10 kOhms with a resistor ratio of 1, ensuring simplified circuit design. It operates at a maximum frequency of 250 MHz with a power dissipation rating of 150 mW. The component supports a maximum operating temperature of +150°C and includes an emitter-base voltage of -1.7 V.

Feature Summary

• Integrates built-in biasing resistors to reduce external component count
• Optimized for high-speed switching applications up to 250 MHz
• Compact SOT-723 surface-mount packaging for space-constrained designs

Applications

• General-purpose signal switching circuits
• Driver stages for logic interfaces
• Battery protection circuits in portable devices

Procurement Notes

Verify the specific suffix 'EMT2L' versus 'YMT2L' against official ROHM documentation, as datasheet discrepancies exist regarding exact pinout and electrical tolerances. Confirm RoHS compliance status directly from the manufacturer's latest release notes. Ensure the sourcing channel provides valid traceability for the VMT3 package variant. Cross-reference the part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for low-voltage logic interfacing. The 10 kOhm input resistance suits standard TTL and CMOS levels. Consider the 70 mA current limit for load driving capabilities. Evaluate the SOT-723 footprint constraints against PCB layout requirements. Compare thermal performance against alternative packages if power dissipation exceeds 150 mW limits.

Part Context

This part belongs to the DTA014E series of pre-biased bipolar transistors from ROHM. It shares functional similarities with other members like DTA014EMT2L but differs in specific electrical ratings and package variations. The series is designed for general-purpose use where space saving and simplified biasing networks are priorities. It complements NPN counterparts such as the DTC series within ROHM's portfolio.

Replacement Considerations

DTA014EMT2L serves as a direct functional substitute within the same product family, though verification of specific electrical parameter differences is required.
