PDTA143TMB,315

Overview

The Nexperia PDTA143TMB is a PNP Resistor-Equipped Transistor (RET) housed in a DFN1006B-3 (SOT883B) leadless ultra-small SMD plastic package. It integrates a single bias resistor R1 of 4.7 kΩ with an open emitter-base resistor configuration. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous output current (IO) of -100 mA. Total power dissipation reaches 250 mW at 25 °C ambient temperature, with a junction temperature limit of 150 °C. Transition frequency (fT) is typically 180 MHz at IC = -10 mA. The component is AEC-Q101 qualified for automotive environments.

Feature Summary

• Integrates built-in bias resistors to reduce component count and simplify circuit design
• Features a leadless ultra-small SMD plastic package with a low profile height of 0.37 mm
• Qualified according to the AEC-Q101 standard for automotive applications

Applications

• Low-current peripheral driver circuits
• Control of IC inputs
• Replacement for general-purpose transistors in digital applications
• Mobile applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details and availability status. Confirm that the DFN1006B-3 footprint matches the target PCB layout requirements. Ensure compliance with RoHS directives and check for any recent product change notices affecting the manufacturing process or material composition before finalizing procurement orders.

Selection Notes

Select this component when a compact PNP switching solution with integrated base biasing is required. The open R2 configuration distinguishes it from variants with parallel emitter-base resistors. Verify that the -50 V rating and -100 mA current capability align with the load requirements. Consider the thermal resistance characteristics if operating in high-temperature environments without adequate PCB copper area for heat dissipation.

Part Context

This part belongs to the PDTA143T series of PNP resistor-equipped transistors manufactured by Nexperia. It serves as the PNP counterpart to the PDTC143TMB NPN variant. The device utilizes the SOT883B package version, providing a smaller footprint compared to traditional SOT-23 packages while maintaining similar electrical performance characteristics for space-constrained designs.

Replacement Considerations

PDTC143TMB is the complementary NPN device within the same series.
