PDTB143ETVL

Overview

The PDTB143ETVL is a PNP Resistor-Equipped Transistor (RET) from the PDTB1xxxT series, housed in an SOT23 (TO-236AB) surface-mounted plastic package. It features built-in bias resistors with a nominal value of 4.7 kΩ for both input and base-emitter connections, maintaining a ±10% ratio tolerance. The device supports a collector-emitter voltage of -50 V and an output current capability of -500 mA. Qualified under AEC-Q101 standards, it operates within a junction temperature range up to 175 °C, providing high-temperature reliability for digital switching applications.

Feature Summary

• Integrates dual bias resistors to simplify circuit design and reduce component count
• AEC-Q101 qualified for automotive environment reliability
• Supports high-temperature operation up to 175 °C junction temperature

Applications

• IC inputs control
• Switching loads
• Cost-saving alternative to BC807 or BC817 series transistors in digital applications

Procurement Notes

Verify the specific suffix 'VL' against official Nexperia documentation to confirm tape-and-reel packaging specifications and manufacturing origin. Ensure the ordering code matches the required resistor tolerance and package variant. Confirm availability through authorized distributors as supply chain parameters are subject to change.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for space-constrained designs. The 4.7 kΩ resistor configuration suits standard logic interface levels. Verify that the -50 V rating and -500 mA current capacity meet the load requirements. Consider the SOT23 footprint constraints during PCB layout planning.

Part Context

This part belongs to the PDTB1xxxT family of PNP resistor-equipped transistors manufactured by Nexperia. The series offers various resistor values and configurations within the SOT23 package. The PDTB143ET variant specifically denotes the 4.7 kΩ / 4.7 kΩ resistor combination, while the 'VL' suffix indicates specific packaging or manufacturing details defined by the manufacturer.

Replacement Considerations

BC807 or BC817 series transistors may serve as functional replacements in digital applications if external biasing resistors are added to the circuit design. Verify pin compatibility and thermal characteristics before substitution.
