Overview
The PDTC123ET-QR is an NPN digital transistor manufactured by Nexperia, designed for surface-mount applications. It integrates a single NPN bipolar junction transistor with an internal base resistor within a compact SOT-23 (TO-236AB) package. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 100 mA. Internal specifications include a typical input resistance of 2.2 kΩ and a power dissipation capacity of 250 mW. The component operates across a temperature range from -55°C to +150°C and holds AEC-Q101 qualification for automotive reliability.
Feature Summary
- Integrated NPN transistor with built-in base resistor simplifies circuit design by reducing external component count.
- Qualified to AEC-Q101 standards for robust performance in demanding automotive electronic environments.
- Compact SOT-23 packaging enables efficient space utilization on high-density printed circuit boards.
Applications
- Switching applications in automotive infotainment and control modules
- Level shifting and logic interface circuits in vehicle electronics
- General-purpose switching in industrial control systems
Procurement Notes
Verify the specific suffix ET against official Nexperia documentation to confirm pinout configuration and reel specifications. Ensure the QR designation aligns with required automotive qualification standards. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when an NPN digital switch with integrated biasing is required in space-constrained designs. Verify that the 50 V collector-emitter voltage and 100 mA current ratings exceed the maximum operational loads. Confirm compatibility with the SOT-23 footprint and ensure the operating temperature range meets the environmental requirements of the target application.
Part Context
This part belongs to the Nexperia PDTA series of pre-biased transistors, which combine discrete transistors with resistors to simplify switching circuits. The PDTC123ET variant specifically denotes an NPN configuration with a 2.2 kΩ base resistor. The product line targets applications requiring reliable, low-component-count solutions for signal switching and level translation in consumer and automotive electronics.
Replacement Considerations
Equivalent parts include the PDTC123ET,215 and PDTC123ET,235 from Nexperia, which share identical electrical characteristics but may differ in packaging quantities or tape-and-reel specifications. Verify pinout compatibility and thermal performance before substitution.
