PDTD113ZUF

Overview

The PDTD113ZUF is an NPN Resistor-Equipped Transistor (RET) from the PDTD1xxxU series, manufactured by Nexperia USA Inc. It integrates a transistor with built-in bias resistors in a SOT323 (SC-70) surface-mount package. Key electrical parameters include a collector-emitter voltage of 50 V and an output current capability of 500 mA. The device features a 1 kΩ input bias resistor (R1) and a 10 kΩ base-emitter bias resistor (R2). It offers a DC current gain (hFE) of at least 70 at 50 mA and 5 V, with a maximum collector-emitter saturation voltage of 100 mV under specified conditions.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce component count
• AEC-Q101 qualified for automotive applications
• High temperature operation up to 175 °C junction temperature
• ±10% resistor ratio tolerance

Applications

• Controlling IC inputs
• Switching loads
• Cost-saving alternative to BC807 or BC817 series transistors in digital applications

Procurement Notes

Verify the specific suffix 'F' against official Nexperia documentation to confirm tape and reel packaging details, as datasheets may list standard bulk or cut tape options. Ensure the ordering code matches the required quantity format. Confirm RoHS compliance status and manufacturing origin codes via the latest product data sheet before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN switching solution with integrated biasing is required. The PDTD113ZUF variant specifically provides a 1 kΩ input resistor and a 10 kΩ base-emitter resistor, suitable for driving logic outputs directly. Consider the SOT323 package size constraints and the 50 V voltage rating relative to the application's supply voltage and load requirements.

Part Context

This part belongs to the PDTD1xxxU series of NPN resistor-equipped transistors. It is complemented by the PDTB113ZU PNP counterpart. The series shares common thermal characteristics and package dimensions but varies in internal resistor values. The 'ZU' designation indicates specific resistor ratios within the SC-70 footprint family.

Replacement Considerations

Direct functional substitutes within the same series include PDTD113EU, which shares identical pinout and general specifications but differs in internal resistor configurations. Verify compatibility with existing PCB footprints and ensure that the alternative part's resistor values meet the specific biasing requirements of the target circuit design.
