DTA114EUBTL

Overview

The DTA114EUBTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in biasing resistors within a single SOT-323FL-3 (UMT3F) package. It provides a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. The device includes an input resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 10 kOhms, resulting in a typical resistance ratio of 1. Key electrical characteristics include a minimum DC current gain (hFE) of 30 at -5 mA and -5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 200 mW. The unit supports surface mount installation with a maximum operating temperature of +150°C.

Feature Summary

• Integrates PNP transistor with dual internal biasing resistors to simplify circuit design
• Eliminates the need for external input components by providing configured R1 and R2 values
• Optimized for high-speed switching applications with a 250 MHz maximum operating frequency

Applications

• Inverter circuits requiring compact pre-biased switching elements
• General-purpose digital logic interface and level shifting
• Battery-powered portable devices where space and component count are constrained

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm package dimensions and tape/reel specifications. Ensure that the selected variant meets all required automotive or industrial qualification standards if applicable to the target system environment.

Selection Notes

Select this component when a PNP configuration with equal 10kOhm biasing resistors is required. Compare the -50 V breakdown voltage and -100 mA current limits against the load requirements. Consider the SOT-323FL-3 footprint compatibility during PCB layout planning.

Part Context

This part belongs to the DTA series of digital transistors from ROHM Semiconductor. The 'EUB' designation typically indicates the specific resistor network configuration and the UMT3F/SOT-323FL package style. It serves as a discrete solution for replacing multiple discrete components in low-power switching applications.

Replacement Considerations

DTA114EU3HZG offers similar electrical specifications but utilizes the standard SOT-323 package instead of the thinner SOT-323FL form factor.
