PDTC143TMB,315

Overview

The PDTC143TMB,315 is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia. It integrates a single NPN transistor with internal biasing resistors in a compact SOT-883 surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a continuous collector current rating of 100 mA. Internal resistance values include a base resistor (R1) of 4.7 kΩ and an emitter-base resistor (R2) of 10 kΩ. It operates within a temperature range of -65°C to +150°C and complies with RoHS standards.

Feature Summary

• Integrates NPN transistor with dual biasing resistors for simplified circuit design
• Compact SOT-883 surface-mount package suitable for space-constrained applications
• High thermal stability with extended operating temperature range up to 150°C

Applications

• Switching applications in portable electronic devices
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the complete part number including the suffix ,315 to ensure correct packaging configuration. Confirm RoHS compliance status and check for any specific automotive or industrial qualification requirements relevant to the target application environment before finalizing procurement specifications.

Selection Notes

Select this component when a pre-biased NPN solution is required to reduce external component count. Ensure the 50 V voltage rating and 100 mA current capacity meet the load requirements. Verify that the SOT-883 footprint matches the PCB layout constraints and that the internal resistor ratios suit the drive conditions.

Part Context

This part belongs to the PDTC143 series of NPN resistor-equipped transistors. It serves as the SOT-883 packaged variant of the standard PDTC143T, offering a smaller form factor compared to traditional SOT-23 packages while maintaining identical electrical characteristics and internal resistor configurations for equivalent performance.

Replacement Considerations

Direct substitutes include other NPN RETs with similar 50V/100mA ratings and comparable R1/R2 values. Check pinout compatibility and package dimensions when considering alternatives from other manufacturers to ensure seamless integration without PCB redesign.
