DTA143XE-TP

Overview

The DTA143XE-TP is a pre-biased PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single bipolar junction transistor with internal biasing resistors R1 and R2 within an SOT-523 surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA, with a transition frequency of 250 MHz and maximum power dissipation of 150 mW. Internal resistor values are specified as 4.7 kOhms for the base (R1) and 47 kOhms for the emitter (R2). DC current gain is rated at a minimum of 80 at 10 mA and 5 V, while saturation voltage remains below 300 mV under defined test conditions.

Feature Summary

• Integrates a PNP BJT with dual internal biasing resistors to simplify circuit design
• Utilizes compact SOT-523 surface-mount packaging for space-constrained applications
• Provides high-speed switching capability with a 250 MHz transition frequency

Applications

• General-purpose switching circuits requiring integrated biasing
• Driver stages for logic interfaces and signal conditioning
• Low-power consumer electronics utilizing surface-mount assembly

Procurement Notes

Verify component authenticity through authorized MCC distributors or certified suppliers. Confirm RoHS3 compliance and lead-free status via official datasheets. Request batch-specific documentation to ensure adherence to REACH regulations and halogen-free manufacturing standards. Validate part markings against the SOT-523 package specifications to prevent counterfeit substitution.

Selection Notes

Select this component when a PNP configuration with specific 4.7k/47k resistor ratios is required in an SOT-523 footprint. Ensure the 50 V breakdown voltage and 100 mA current limits align with load requirements. Compare against alternative packages like SOT-23 if higher power dissipation or different thermal characteristics are necessary for the target application.
