DTA014YEBTL

Overview

The DTA014YEBTL is a single PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -70 mA. The device includes an input resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 47 kOhms, resulting in a typical resistance ratio of 4.7. Key electrical characteristics include a minimum DC current gain (hFE) of 80 at -5 mA and -10 V, a transition frequency of 250 MHz, and a maximum power dissipation of 150 mW. It is housed in the EMT3F (SOT-416FL) surface-mount package.

Feature Summary

• Integrates internal biasing resistors to eliminate external components for inverter circuits
• Provides high-speed switching capability with a 250 MHz transition frequency
• Offers compact surface-mount packaging for space-constrained designs

Applications

• Inverter circuits requiring simplified input stages
• General-purpose switching applications in consumer electronics
• Driver circuits for low-current loads

Procurement Notes

Verify the specific suffix EBTL against the manufacturer's datasheet to confirm the exact package variant and tape-and-reel specifications. Ensure compatibility with RoHS3 standards if required by the target market regulations. Cross-reference the part number with official ROHM documentation to avoid confusion with similar series members like DTA014EUBTL or DTA023YEBTL which differ in polarity or resistance values.

Selection Notes

Select this component when a PNP digital transistor with a 10k/47k resistor ratio is required. The -70 mA collector current limit defines its suitability for low-power switching tasks. Compare the 150 mW power dissipation rating against thermal constraints in the final assembly. Verify that the SOT-416FL footprint matches the PCB layout requirements before finalizing the bill of materials.

Part Context

This part belongs to the DTA014 series of pre-biased transistors from ROHM. It serves as the PNP counterpart to the NPN DTC014 series. The series is designed for standard-level applications and is explicitly noted as not recommended for automotive equipment. It replaces discrete resistor-transistor combinations in logic interfaces.

Replacement Considerations

DTA114YE3TL offers a similar PNP configuration with identical 10k/47k resistor ratios but uses the EMT3 (SOT-416) package instead of EMT3F. Designers must verify pinout compatibility and mechanical height differences between the SOT-416 and SOT-416FL packages before substitution.
