DTA114YETL

Overview

The DTA114YETL is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It integrates bias resistors with typical values of R1 at 10 kOhms and R2 at 47 kOhms, yielding a resistance ratio of 4.7. The device supports a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 68 at -5 mA and -5 V, a transition frequency of 250 MHz, and a power dissipation rating of 150 mW. It operates within a temperature range up to +150 C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design by eliminating the need for external input components.
• Provides high-speed switching capabilities suitable for applications requiring fast response times.

Applications

• Inverter circuits
• Interface logic
• Driver stages

Procurement Notes

Verify the specific suffix 'ETL' against the manufacturer's datasheet to confirm the reel packaging configuration and tape-and-reel specifications. Ensure that the ordering information matches the exact RoHS compliance status and flammability ratings required for the target assembly process. Cross-reference the component marking with official documentation to prevent substitution errors during procurement.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for space-constrained designs. The SOT-416 package offers a small footprint suitable for dense PCB layouts. Consider the 10 kOhm input resistance value to ensure compatibility with the driving source impedance and logic levels of the control circuitry.

Part Context

This part belongs to the DTA114 series of digital transistors from ROHM Semiconductor. The series includes complementary NPN types such as the DTC114YE. These devices are designed to replace discrete resistor-transistor combinations, reducing board space and assembly costs while maintaining consistent electrical characteristics across production batches.

Replacement Considerations

Publicly confirmed substitute part numbers include DTA114YE3TL and DTA114WE. Verify pinout compatibility and electrical parameter tolerances before substituting. Ensure the alternative component meets the same thermal and voltage requirements for the specific application environment.
