PDTA143TT,215

Overview

The PDTA143TT,215 is a PNP resistor-equipped transistor (RET) manufactured by Nexperia in the SOT-23 (TO-236AB) surface-mount package. It integrates a single internal bias resistor (R1) with an open R2 configuration. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -50 V and a continuous DC output current (IO) of -100 mA. The typical input resistance (R1) is 4.7 kΩ, with a specified range of 3.3 kΩ to 6.1 kΩ. The device supports a total power dissipation of 250 mW at 25 °C ambient temperature and operates within a junction temperature range up to 150 °C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Reduces pick and place costs through consolidated discrete functionality.
• Features a standard SOT-23 plastic surface-mounted package for compact PCB layouts.

Applications

• General purpose switching and amplification
• Inverter and interface circuits

Selection Notes

Select this component when a PNP digital transistor with a 4.7 kΩ base resistor is required. Ensure the -50 V voltage rating and -100 mA current capacity meet the load requirements. Verify that the SOT-23 footprint aligns with the PCB layout constraints and that the thermal resistance characteristics are suitable for the intended operating environment.

Part Context

This part belongs to the PDTA143T series of PNP resistor-equipped transistors from Nexperia. The series includes variants with different packages such as SOT883, SOT323, and TO-92. The PDTA143TT specifically denotes the SOT-23 package version. The NPN complement for this device is the PDTC143TT.

Replacement Considerations

Direct substitutes within the same series include PDTA143TM (SOT883 package). Cross-package equivalents require verifying pinout compatibility and thermal performance differences between SOT-23 and alternative footprints like SOT323 or SOT883.
