DTA124XCA-TP

Overview

The DTA124XCA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN bipolar junction transistor with internal biasing resistors in a compact SOT-23 surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. Internal resistor values are specified as R1 at 4.7 kOhms and R2 at 47 kOhms. Key electrical characteristics include a DC current gain (hFE) minimum of 100 at 10 mA and 5 V, a saturation voltage of 300 mV at 250 µA base current and 5 mA collector current, and a transition frequency of 250 MHz.

Feature Summary

• Integrates an NPN transistor with dual biasing resistors for simplified circuit design
• Provides high DC current gain to reduce drive requirements
• Optimized for low saturation voltage to minimize power dissipation
• Utilizes a compact SOT-23 package for efficient space utilization

Applications

• General-purpose switching applications
• Driver circuits for logic interfaces
• Level shifting between different voltage domains

Procurement Notes

Verify the specific suffix 'CA' against the manufacturer's latest datasheet to confirm pinout configuration and internal resistance tolerances. Ensure compliance with RoHS directives and check for automotive qualification status if required for the target application environment.

Selection Notes

Select this component when a PNP digital transistor with integrated dual biasing resistors is required. Compare the 4.7 kOhm input resistance and 47 kOhm emitter resistor values against circuit requirements. Consider the SOT-23 package constraints and thermal dissipation limits relative to the load current.

Part Context

This part belongs to the DTA124 series of pre-biased transistors from MCC. The series offers various resistor combinations within standard packages like SOT-23. The DTA124XCA-TP specifically denotes the PNP type with defined internal resistance ratios, distinguishing it from other variants in the family with different resistor values or configurations.

Replacement Considerations

Cross-reference with other manufacturers offering PNP digital transistors in SOT-23 packages. Verify that substitute parts match the 50 V rating, 100 mA current capacity, and similar internal resistor values (R1=4.7k, R2=47k) to ensure functional compatibility without redesign.
