PDTA143XT,215

Overview

The PDTA143XT,215 is a PNP Resistor-Equipped Transistor (RET) in an SOT23 surface-mounted package. It integrates bias resistors R1 and R2 with a single PNP transistor to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, an output current (IO) of -100 mA, and a total power dissipation (Ptot) of 250 mW at 25 °C. The typical input bias resistor R1 is 4.7 kΩ, with a bias resistor ratio (R2/R1) of 2.1. The device features a transition frequency (fT) of 180 MHz and a DC current gain (hFE) of 50 at IC = -10 mA.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact packaging configuration and manufacturing site code. Ensure compatibility with standard reflow soldering processes as specified in the datasheet. Confirm RoHS compliance status for the specific batch prior to integration into production designs.

Selection Notes

Select this component when a compact PNP switching solution with integrated base biasing is required. The SOT23 package offers a small footprint suitable for space-constrained designs. Consider the thermal resistance characteristics and power derating curves if operating in high ambient temperature environments or under continuous load conditions.

Part Context

This part belongs to the PDTA143X series of PNP resistor-equipped transistors from Nexperia. The series includes variants in different packages such as SOT416, SOT883, and SOT323. The PDTA143XT specifically utilizes the SOT23 package, providing a cost-saving alternative to discrete transistor and resistor combinations in digital logic circuits.

Replacement Considerations

PDTC143XT is the NPN complement within the same family. Other package variants like PDTA143XE, PDTA143XM, and PDTA143XU share similar electrical characteristics but differ in physical dimensions and thermal properties.
