Overview
The PDTC143EQCZ is an NPN Resistor-Equipped Transistor (RET) from the Nexperia PDTC143/114/124/144EQC series. It features a maximum collector-emitter voltage of 50 V and a continuous output current capability of 100 mA. The device integrates bias resistors R1 and R2, both with a typical value of 4.7 kΩ. It is housed in a DFN1412D-3 (SOT8009) leadless surface-mount package measuring 1.4 x 1.2 x 0.48 mm. Key electrical characteristics include a DC current gain (hFE) minimum of 30 at 10 mA, a transition frequency of 230 MHz, and a total power dissipation of 360 mW on a standard FR4 PCB.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Ultra-small DFN1412D-3 package with side-wettable flanks for improved solder joint inspection.
- Low profile height of 0.5 mm suitable for space-constrained applications.
Applications
- Digital logic switching applications
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact reel or cut tape configuration intended for your assembly process. Confirm that the DFN1412D-3 footprint matches your PCB layout guidelines. Ensure compliance with RoHS directives and check for any specific automotive qualification requirements if deploying in vehicle electronics.
Selection Notes
Select this component when a compact NPN transistor with integrated base and emitter resistors is required. The 4.7 kΩ resistor values are suitable for general digital interfacing. Consider the thermal resistance values provided in the datasheet for heat dissipation planning. Verify that the 50 V breakdown voltage meets the system's operating conditions.
Part Context
This part belongs to the PDTC143/114/124/144EQC series, which offers various resistor combinations within the same ultra-small DFN1412D-3 package. The PDTC143 variant specifically utilizes equal 4.7 kΩ resistors for R1 and R2. The PNP complement for this specific configuration is the PDTA143EQC.
Replacement Considerations
Direct pin-compatible replacements within the same series include PDTC114EQC, PDTC124EQC, and PDTC144EQC, though these feature different internal resistor values. The PNP equivalent is PDTA143EQC. Cross-brand replacements require verification of pinout, voltage ratings, and package dimensions.
