DTA114TUA-TP

Overview

The DTA114TUA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in an SOT-323 surface-mount package. It integrates thin-film bias resistors to enable inverter circuit configuration without external input components. Key electrical parameters include a collector-emitter breakdown voltage of -50 V, continuous collector current of -100 mA, and power dissipation of 200 mW at 25°C. The device features a typical input resistance of 10 kOhms, a DC current gain minimum of 250, and a transition frequency of 250 MHz.

Feature Summary

• Built-in bias resistors allow for inverter circuit configuration without connecting external input resistors
• Thin-film resistors provide complete isolation to eliminate parasitic effects and permit negative biasing
• Simplified operation requires setting only On/Off conditions

Applications

• Inverter circuits
• Switching applications requiring simplified design
• Digital logic interface circuits

Procurement Notes

Verify the component authenticity through authorized MCC distributors or direct manufacturer channels to ensure full traceability and compliance with quality standards. Confirm that the ordering suffix indicates RoHS compliance as specified in the official documentation. Check for specific packaging requirements such as tape and reel quantities before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs using the SOT-323 package. Ensure the application voltage does not exceed the -50 V collector-emitter rating and that the thermal environment supports the 200 mW power dissipation limit. Verify compatibility with the 10 kOhm internal resistance for the intended drive conditions.

Part Context

This part belongs to the DTA114 series of pre-biased NPN/PNP transistors from Micro Commercial Components. These devices are designed to replace discrete resistor-transistor combinations, reducing board space and assembly complexity. The 'TP' suffix typically denotes the specific packaging and compliance configuration offered by the manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing should be performed carefully against datasheet parameters such as pinout, voltage ratings, and internal resistance values.
