DTA114EUA-TP

Overview

The DTA114EUA-TP is a pre-biased PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single BJT with bias resistors in an SOT-323 surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of -50 V, a continuous collector current of -100 mA, and a transition frequency of 250 MHz. The device features a minimum DC current gain (hFE) of 30 at 5 mA and 5 V, with a power dissipation rating of 200 mW. Internal resistors are typically 10 kOhms each, yielding a ratio of 1. It operates up to +150°C and meets RoHS standards.

Feature Summary

• Integrates a PNP bipolar junction transistor with dual internal bias resistors for simplified circuit design.
• Optimized for high-speed switching applications with a 250 MHz transition frequency.
• Designed for surface-mount assembly in compact SOT-323 packages.

Applications

• General-purpose switching circuits
• Driver circuits for logic interfaces
• High-frequency signal processing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and electrical tolerances. Ensure that the selected variant matches the required thermal management specifications for the intended operating environment. Cross-reference component markings with official documentation to prevent counterfeit substitution during sourcing.

Selection Notes

Select this component when a compact PNP solution with integrated base and emitter resistors is required. The SOT-323 package suits space-constrained designs. Verify that the -50 V collector-emitter voltage and -100 mA current ratings exceed the maximum load requirements. Confirm that the 200 mW power dissipation capability aligns with the thermal constraints of the PCB layout.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from MCC. It shares the same functional architecture as other variants in the family but differs in resistor values or packaging. The 'EUA' suffix typically denotes specific resistor configurations within the SOT-323 form factor, distinguishing it from larger packages like SOT-23.

Replacement Considerations

Direct substitutes include DTA114EUAHE3-TP, which offers identical electrical characteristics and AEC-Q101 automotive qualification. Other compatible alternatives within the same series should be verified for matching hFE ranges and resistor ratios before implementation.
