PDTC114YU-QF

Overview

The PDTC114YU-Q is an NPN Resistor-Equipped Transistor (RET) housed in a SOT323 (SC-70) surface-mount package. It integrates bias resistors R1 and R2, with nominal values of 10 kΩ and 47 kΩ respectively. The device supports a collector-emitter voltage (VCEO) of 50 V and an output current capability of 100 mA. Key electrical characteristics include a DC current gain (hFE) of at least 100 at 5 mA, a transition frequency (fT) of 230 MHz, and a maximum power dissipation of 200 mW. It operates within an ambient temperature range of -65 °C to +150 °C.

Feature Summary

• Qualified according to AEC-Q101 for automotive applications.
• Low profile SC-70 plastic package reduces pick and place costs.

Applications

• Digital applications in automotive and industrial segments
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel size or tape-and-reel specifications. Confirm that the requested part number matches the exact electrical parameters and qualification standards required for the target application before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN transistor solution with integrated base and emitter resistors is required. Ensure the 50 V collector-emitter voltage rating and 100 mA current capacity align with the load requirements. Verify that the SC-70 package dimensions fit the available PCB space constraints.

Part Context

This component belongs to Nexperia's family of resistor-equipped transistors designed to replace multiple discrete components. It serves as a cost-effective alternative for general-purpose switching tasks, offering a simplified design approach by integrating necessary biasing elements directly into the semiconductor package.

Replacement Considerations

The PDTA114YU-Q is the PNP complement within the same series. For direct replacement in existing designs, verify pin compatibility and ensure the opposite polarity meets the circuit requirements.
