PDTC143TU/ZLF

Overview

The PDTC143TU/ZLF is an NPN resistor-equipped transistor from the PDTC143T series, manufactured by Nexperia. It integrates a single bias resistor (R1) with a nominal value of 4.7 kΩ, while R2 remains open. The device is housed in the SOT323 surface-mount package and supports a collector-emitter voltage (VCEO) of -50 V and a continuous DC output current (IO) of -100 mA. Total power dissipation is rated at 200 mW at 25 °C ambient temperature. The component operates within an ambient temperature range of -65 °C to +150 °C.

Feature Summary

Built-in bias resistors simplify circuit design and reduce component count.
Reduces pick and place costs for automated assembly processes.

Applications

General purpose switching
Amplification circuits
Inverter and interface circuits

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance details. Confirm that the ZLF designation aligns with the required RoHS status and halogen-free specifications for your project. Ensure compatibility with standard reflow soldering profiles as specified in the datasheet thermal characteristics section.

Selection Notes

Select this component when a compact NPN solution with integrated base biasing is required. The SOT323 package offers a small footprint suitable for space-constrained designs. Verify that the 4.7 kΩ internal resistor value meets the drive requirements for the intended load current and logic levels.

Part Context

This part belongs to the PDTC143T series, which includes various packages such as SOT23, SOT346, and SOT883. The TU suffix specifically denotes the SOT323 (SC-70) plastic surface-mounted package variant. The series provides a standardized solution for replacing discrete resistor-transistor combinations in digital logic applications.

Replacement Considerations

Direct pin-compatible alternatives within the same series include PDTC143TT (SOT23) or PDTC143TK (SOT346), provided the package footprint can be adapted. Ensure the replacement maintains the same electrical ratings and internal resistor configuration.
