PDTC143TE,115

Overview

The PDTC143TE,115 is an NPN resistor-equipped transistor manufactured by Nexperia (formerly NXP Standard Products). It integrates a single bias resistor (R1) of 4.7 kΩ with the emitter left open (R2 = open). The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous DC output current (IO) of 100 mA. It is housed in the SOT416 surface-mount package (SC-75), which has a maximum total power dissipation of 150 mW at 25 °C ambient temperature. The component features a minimum DC current gain (hFE) of 200 at IC = 1 mA.

Feature Summary

• Built-in bias resistor simplifies circuit design and reduces component count
• Reduces pick and place costs for automated assembly
• Suitable for general purpose switching and amplification applications

Applications

• General purpose switching
• Amplification circuits
• Inverter and interface circuits

Procurement Notes

Verify the manufacturer origin code associated with the ordering suffix to confirm production location. Confirm that the specific package variant matches the required footprint dimensions and pin configuration for the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a single base resistor is sufficient for biasing requirements. Ensure the application current does not exceed 100 mA and the voltage remains below 50 V. Verify thermal constraints as the SC-75 package limits power dissipation to 150 mW.

Part Context

This part belongs to the PDTC143T series of NPN resistor-equipped transistors. The series includes multiple package options such as SOT490, SOT346, and SOT883. The PDTC143TE specifically utilizes the SOT416 (SC-75) plastic surface-mounted package with three leads.

Replacement Considerations

The PDTA143TE is the PNP complement within the same series. Other packages in the series include PDTC143TEF (SOT490), PDTC143TK (SOT346), and PDTC143TM (SOT883).
