PDTC143TT,215

Overview

The PDTC143TT,215 is an NPN resistor-equipped transistor (RET) manufactured by Nexperia. It integrates a single bias resistor (R1 = 4.7 kΩ) with the collector-base junction left open. The device is housed in a SOT23 surface-mounted plastic package and supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous DC output current (IO) of 100 mA. Total power dissipation is rated at 250 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 resistor simplifies circuit design and reduces component count
• Single NPN transistor configuration with integrated base resistor
• Surface-mount construction for automated pick-and-place assembly

Applications

• General purpose switching and amplification
• Inverter circuits
• Interface circuits

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Confirm that the SOT23 package variant matches the required footprint for PCB layout. Ensure the R1 value of 4.7 kΩ aligns with the target biasing requirements before finalizing procurement orders.

Selection Notes

Select this component when a discrete NPN transistor requires a fixed base bias network. The internal 4.7 kΩ resistor eliminates external components, saving board space. Verify that the 100 mA current rating and 50 V voltage limits accommodate the peak load conditions of the intended application without exceeding thermal constraints.

Part Context

This part belongs to the PDTC143T series of NPN resistor-equipped transistors. It serves as the complement to the PDTA143TT PNP RET. The 'TT' designation indicates the SOT23 package style, while the ',215' suffix denotes the standard reel packaging format used for high-volume surface-mount production lines.

Replacement Considerations

Direct functional substitutes include other NPN RETs with identical 4.7 kΩ base resistance and SOT23 footprints. Cross-reference with PDTA143TT if a PNP equivalent is required. Verify pinout compatibility, as some RET packages utilize different emitter-collector arrangements.
