DTA014EMT2L

Overview

The DTA014EMT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors to simplify circuit design. It operates with a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes a typical input resistance (R1) of 10 kOhms and an emitter-base resistance (R2) of 10 kOhms, maintaining a resistor ratio of 1. Key electrical parameters include a minimum DC current gain (hFE) of 35 at -5 mA and -10 V, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. It is housed in a compact SOT-723-3 surface-mount package.

Feature Summary

• Integrates PNP transistor with dual built-in biasing resistors for simplified inverter circuit configuration
• Provides high-speed switching capability with a 250 MHz transition frequency
• Offers robust operation with a -50 V supply voltage rating and -100 mA collector current capacity

Applications

• Inverter circuits requiring simplified biasing networks
• Interface applications between logic gates and loads
• Driver circuits for low-power switching tasks

Procurement Notes

Verify the specific suffix 'T2L' corresponds to the SOT-723-3 package and taping format when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is required.

Selection Notes

Select this component for designs needing a pre-biased PNP solution in a small footprint. The 10 kOhm resistor values are suitable for general-purpose logic interfacing. Compare against complementary NPN types like the DTC014 series if symmetrical push-pull configurations are necessary. Verify thermal constraints given the 150 mW power dissipation limit in the SOT-723 package.

Part Context

This part belongs to the DTA014E series of digital transistors from ROHM Semiconductor. It shares functional similarities with other members of the family but differs in packaging and specific resistor tolerances. The T2L suffix typically denotes the specific tape-and-reel packaging variant for automated assembly processes.

Replacement Considerations

Direct substitutes may include other PNP digital transistors with similar -50V ratings and 10k/10k resistor ratios, such as parts from ON Semiconductor or STMicroelectronics. Verify pinout compatibility and hFE characteristics before substitution.
