DTA114EUAHE3-TP

Overview

The DTA114EUAHE3-TP is a PNP digital transistor from Micro Commercial Components, housed in an SOT-323 package. It integrates internal bias resistors with R1 at 10 kΩ and R2 at 10 kΩ, yielding a resistance ratio of 1. The device supports a maximum supply voltage (VCC) of -50 V and a continuous collector current (IC) of -100 mA. Key electrical parameters include a DC current gain (hFE) minimum of 30, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 200 mW. It operates within a junction temperature range up to 150°C and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Built-in bias resistors eliminate the need for external input components, simplifying circuit design by enabling direct connection as a switch or inverter.
• AEC-Q101 qualified for automotive reliability requirements.
• Halogen-free 'Green' device compliant with environmental standards.
• Moisture sensitivity level 1 with UL 94 V-0 flammability rating epoxy.

Applications

• Automotive electronic control units requiring pre-biased switching.
• General-purpose digital logic interface circuits.
• High-frequency signal processing applications utilizing 250 MHz transition frequency.

Procurement Notes

Verify authenticity through authorized MCC distributors to avoid counterfeit parts. Confirm RoHS compliance via the '-P' suffix designation. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines. Check for specific automotive grade certifications if used in critical systems. Review datasheet revisions for any updates to mechanical dimensions or electrical limits before finalizing procurement orders.

Selection Notes

Select this component for PNP switching applications requiring integrated base resistance. The 10 kΩ input resistor suits standard logic levels. Verify that the -50 V collector-emitter voltage and -100 mA current ratings exceed circuit demands. Consider the SOT-323 package size for space-constrained PCB layouts. Ensure thermal management accommodates the 200 mW power dissipation limit at expected ambient temperatures.

Part Context

This part belongs to the DTA114 series of pre-biased transistors manufactured by Micro Commercial Components. The HE3 suffix indicates Halogen-free and RoHS-compliant packaging. It serves as a compact solution replacing discrete BJT and resistor combinations in digital switching roles.

Replacement Considerations

DTA114EUA-TP is a similar non-automotive grade variant. DTA114EUAFRA is a discontinued equivalent with identical pinout and specifications. Verify package compatibility and electrical tolerances when substituting.
