DTA114YUA-TP

Overview

The DTA114YUA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in an SOT-323 package. It integrates thin-film bias resistors with complete isolation to enable negative input biasing and minimize parasitic effects. Key electrical specifications include a maximum supply voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation rating of 200 mW at 25°C. The device features a typical transition frequency of 250 MHz and a DC current gain (GI) of 68. Internal resistance values are R1 = 10 kΩ and R2 = 47 kΩ, yielding a resistance ratio of 4.7.

Feature Summary

• Built-in bias resistors allow inverter circuit configuration without external input resistors
• Thin-film resistors provide complete isolation for negative input biasing capability
• Halogen-free construction meets UL 94 V-0 flammability rating

Applications

• Inverter circuits requiring simplified design
• Switching applications utilizing on/off conditions
• High-frequency signal processing up to 250 MHz

Procurement Notes

Verify component authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Unauthorized sources lack traceability and quality assurance. Confirm RoHS compliance via the 'P' suffix designation. Ensure storage and handling procedures adhere to Moisture Sensitivity Level 1 standards to maintain device integrity prior to assembly.

Selection Notes

Select this component for designs requiring PNP logic inversion with integrated biasing. The SOT-323 package suits space-constrained surface-mount applications. Verify that the -50 V supply voltage and -100 mA current limits accommodate the specific circuit requirements. Consider the 200 mW power dissipation limit when evaluating thermal management needs at elevated ambient temperatures.
