DTA114EM-TP

Overview

The DTA114EM-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN BJT with internal biasing resistors into a compact SOT-323 surface-mount package. The device features a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 50 V. Internal resistors R1 and R2 are both 10 kOhms, providing a typical ratio of 1. Key electrical specifications include a minimum DC current gain (hFE) of 30 at 5 mA/5 V, a transition frequency of 250 MHz, and a maximum power dissipation of 200 mW.

Feature Summary

• Integrates a pre-biased PNP transistor with dual 10 kOhm resistors for simplified circuit design.
• Optimized for high-speed switching applications with a 250 MHz transition frequency.
• Designed for space-constrained layouts using the standard SOT-323 surface-mount package.

Applications

• General-purpose switching in consumer electronics.
• Driver circuits for low-current loads.
• Logic level translation interfaces.

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm pinout compatibility and resistor values. Ensure the ordering quantity aligns with the manufacturer's reel packaging requirements. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP solution with integrated base and emitter resistors is required. The 10 kOhm resistor values provide a balanced drive capability suitable for standard logic families. Verify that the 50 V voltage rating and 100 mA current limit meet the specific load requirements of the target application circuit.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from Micro Commercial Components. The 'E' suffix typically denotes the SOT-323 package variant within this family. It serves as a direct replacement for discrete resistor-transistor networks, reducing board space and assembly complexity while maintaining consistent electrical performance across production batches.

Replacement Considerations

Cross-reference with other manufacturers' PNP digital transistors in SOT-323 packages. Verify that substitute parts match the 10k/10k resistor configuration and 50V/100mA ratings. Check for identical pinout assignments to ensure mechanical interchangeability without PCB redesign.
