DTA114YE-TP

Overview

The DTA114YE-TP is a pre-biased PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single bipolar junction transistor with internal biasing resistors within an SOT-523 surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. It features a transition frequency of 250 MHz and a power dissipation rating of 200 mW. The integrated resistor network typically includes a base resistor (R1) of 10 kOhms and an emitter resistor (R2) of 10 kOhms, providing a resistance ratio of approximately 1. This component is designed for high-speed switching applications requiring simplified circuit design.

Feature Summary

Procurement Notes

Verify the specific manufacturer part number against official MCC documentation to ensure authenticity. Confirm that the SOT-523 package type matches the design requirements. Check for RoHS compliance status as indicated in the latest datasheet revisions. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage during assembly.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required for high-frequency switching. Compare the 10 kOhm resistor values against the driving source impedance to ensure adequate base current. Verify that the 50 V voltage rating exceeds the maximum circuit operating voltage. Consider the thermal performance of the SOT-523 package under expected load conditions.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from Micro Commercial Components. The series offers various configurations with different resistor ratios and packages. The YE suffix specifically denotes the SOT-523 package variant with defined internal resistance values. This series is commonly used to replace discrete resistor-transistor networks in modern electronic designs.

Replacement Considerations

Cross-reference with other manufacturers offering PNP digital transistors in SOT-523 packages. Verify pinout compatibility and electrical parameter equivalence, particularly Vceo, Ic, and R1/R2 values. Examples include equivalent parts from ROHM or Diodes Incorporated, provided they match the specific resistance ratio and package dimensions.
