DTA143XCA-TP

Overview

The DTA143XCA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single base resistor (R1) of 4.7 kOhms within an SOT-23 surface-mount package. The device supports a maximum collector current (Ic) of 100 mA and a collector-emitter breakdown voltage (Vceo) of 50 V. Key electrical characteristics include a minimum DC current gain (hFE) of 30 at Ic=10mA, Vce=5V, and a maximum saturation voltage (Vce(sat)) of 300 mV at Ib=500µA, Ic=10mA. The component features a transition frequency of 250 MHz, a power dissipation rating of 200 mW, and a maximum collector cutoff current of 500 nA.

Feature Summary

• Integrates a pre-biased PNP transistor with a single internal base resistor for simplified circuit design.
• Provides high-speed switching capabilities with a transition frequency of 250 MHz.
• Offers low saturation voltage to minimize power loss during conduction states.

Applications

• General-purpose switching applications in consumer electronics.
• Driver circuits for small-signal loads requiring pre-biasing.
• Logic interface circuits between microcontrollers and peripheral devices.

Procurement Notes

Verify the specific suffix 'CA' against the manufacturer's datasheet to confirm the integrated resistor configuration and pinout compatibility. Ensure the SOT-23 package dimensions align with the target PCB footprint. Confirm RoHS compliance status through official documentation prior to procurement.

Selection Notes

Select this component when a PNP digital transistor with a 4.7 kOhm base resistor is required. Verify that the 50 V collector-emitter voltage and 100 mA collector current ratings exceed the application's maximum operating conditions. Consider the SOT-23 package size constraints and thermal dissipation requirements relative to the 200 mW power rating.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from MCC. It is functionally similar to other DTA143 variants but distinguished by its specific resistor value and packaging. The 'TP' suffix typically indicates tape and reel or cut tape packaging options available from distributors.

Replacement Considerations

Cross-reference with DTA143ZCA-TP for higher hFE gain (80 vs 30) while maintaining similar voltage and current ratings. Verify pinout compatibility and resistor values before substitution.
