DTA114TE-TP

Overview

The DTA114TE-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in an SOT-523 surface-mount package. It integrates thin-film bias resistors to simplify circuit design. Key electrical specifications include a collector-emitter voltage of -50 V, continuous collector current of -100 mA, and power dissipation of 150 mW at 25°C. The device features a typical input resistance of 10 kΩ, a DC current gain ranging from 100 to 600, and a transition frequency of 250 MHz.

Feature Summary

• Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors
• Thin-film resistors provide complete isolation to allow negative biasing of the input and eliminate parasitic effects
• Halogen-free "Green" device with moisture sensitivity level 1 and epoxy meeting UL 94 V-0 flammability rating

Applications

• Inverter circuits
• Switching applications requiring simplified base drive
• General-purpose digital logic interfacing

Procurement Notes

Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit components. Confirm RoHS compliance via the "-TP" suffix designation. Ensure storage conditions adhere to Moisture Sensitivity Level 1 standards. Check for Product Change Notifications prior to large-scale procurement.

Selection Notes

Select this component for designs requiring a PNP digital transistor with integrated biasing in a compact SOT-523 footprint. Verify that the -50 V voltage rating and -100 mA current capacity meet the specific load requirements. Consider the 10 kΩ input resistance value for appropriate base drive calculations.

Part Context

This part belongs to the DTA114 series of single PNP digital transistors produced by Micro Commercial Components. It is designed as a replacement for discrete resistor-transistor networks, offering space savings on printed circuit boards while maintaining standard switching performance characteristics.

Replacement Considerations

Cross-reference with other PNP digital transistors in the SOT-523 package having similar -50V ratings and ~10kΩ internal bias resistors. Verify pinout compatibility and thermal dissipation limits before substitution.
