Overview
The PDTC143XUF is an NPN Resistor-Equipped Transistor (RET) housed in a SOT323 (SC-70) plastic surface-mounted package. It integrates bias resistors to simplify circuit design and reduce component count. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, an output current (IO) of 100 mA, and a typical input bias resistor (R1) of 4.7 kΩ with a ratio (R2/R1) of 2.1. The device operates within a temperature range of -65 °C to +150 °C and has a total power dissipation of 200 mW at 25 °C ambient.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce pick-and-place costs.
- Qualified to AEC-Q101 standards for automotive applications.
- Provides high breakdown voltage with 100 mA output current capability.
Applications
- Digital applications in automotive and industrial segments
- Control of IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and packing method. The datasheet lists standard tape and reel options for the SOT323 package. Confirm compliance requirements such as RoHS status directly with the supplier or through the latest product data sheet before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN switching solution with integrated base biasing is required. The SOT323 package offers a very small footprint suitable for space-constrained designs. Ensure the application voltage does not exceed the 50 V collector-emitter rating and that the load current remains within the 100 mA continuous limit.
Part Context
This part belongs to the PDTC143X series of NPN Resistor-Equipped Transistors from Nexperia. The 'U' suffix specifically denotes the SOT323 (SC-70) package variant. The series serves as a cost-saving alternative to discrete transistor and resistor combinations, commonly replacing older BC847/857 series components in digital logic circuits.
Replacement Considerations
The PNP complement for this device is PDTA143XU. Other members of the PDTC143X series include variants in SOT23, SOT416, and SOT883 packages, which share similar electrical characteristics but differ in physical dimensions and thermal performance.
