DTA114EKA-TP

Overview

The DTA114EKA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It features an integrated single configuration with a typical base resistor of 10 kOhms and an emitter resistor ratio of 1. The device operates in an SOT-23-3L surface-mount package, supporting continuous collector currents up to -100 mA and power dissipation of 200 mW. Key electrical specifications include a maximum operating frequency of 250 MHz, a minimum DC current gain (hFE) of 30 at 5 mA/5 V, and a saturation voltage of -300 mV at 500 µA base current and 10 mA collector current. It functions within a temperature range extending to +150°C.

Feature Summary

• Integrates a pre-biased PNP transistor with internal resistors to simplify circuit design and reduce component count.
• Provides high-speed switching capabilities suitable for applications requiring operation up to 250 MHz.
• Offers low saturation voltage characteristics to minimize power loss during conduction states.

Applications

• General-purpose switching circuits in consumer electronics.
• Driver stages for relays, solenoids, or small motors.
• Logic level translation and buffer interfaces in digital systems.

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm pinout compatibility and electrical tolerances before integration. Ensure that the SOT-23-3L footprint matches the target PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Validate thermal management requirements based on the 200 mW power dissipation limit under expected operating conditions.

Selection Notes

Select this component when a compact PNP solution with built-in biasing is required for space-constrained designs. Compare the 10 kOhm base resistance against other series variants if different drive currents are needed. Consider the SOT-23-3L package dimensions relative to available board real estate. Evaluate the -100 mA current rating against peak load requirements to ensure adequate margin.
