Overview
The PDTC124XT-QR is a single NPN digital transistor manufactured by Nexperia, housed in an SOT-363 surface-mount package. It integrates a bipolar junction transistor with built-in bias resistors to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. The device features a typical base resistor (R1) of 22 kΩ and an emitter resistor (R2) of 22 kΩ, resulting in a resistor ratio of 1. It operates within a temperature range of -55°C to +150°C and has a power dissipation rating of 250 mW.
Feature Summary
- Integrates a single NPN transistor with dual bias resistors for simplified switching applications
- AEC-Q101 qualified for automotive electronics reliability standards
- Utilizes SOT-363 packaging for compact surface-mount assembly
Applications
- Automotive logic level shifting
- General-purpose switching circuits
- Interface between microcontrollers and peripheral devices
Procurement Notes
Verify the specific suffix XT against official Nexperia documentation to confirm the exact reel size and tape-and-reel configuration. Confirm AEC-Q101 qualification status through the manufacturer's datasheet before finalizing procurement for automotive-grade requirements.
Selection Notes
Select this component when a single NPN switch with integrated biasing is required in a small footprint. Ensure the 50 V voltage rating and 100 mA current capacity meet the load requirements. Compare with the PDTC124ET series if a different package like SOT-23 is preferred instead of SOT-363.
Part Context
This part belongs to Nexperia’s portfolio of Resistor-Equipped Transistors (RETs). These components combine discrete transistors with on-chip resistors to reduce board space and assembly costs. The PDTC124XT-QR specifically targets applications requiring reliable NPN switching with minimal external components.
Replacement Considerations
The PDTC124ET-QR serves as a functional substitute but utilizes an SOT-23 package rather than the SOT-363 form factor of the PDTC124XT-QR. Verify pinout compatibility and physical footprint constraints before substituting.
