NEXPERIA PDTD123YT NPN Digital Transistor, SOT-23, 50V, 500mA, R1 2.2kΩ R2 10kΩ
NEXPERIA PDTD123YT NPN digital transistor with 2.2kΩ & 10kΩ bias resistors. 50V, 500mA, SOT-23 package for industrial & automotive use.
The NEXPERIA PDTD123YT is a compact, high-performance NPN resistor-equipped transistor (RET) designed for efficient surface-mount assembly. This digital transistor integrates bias resistors directly into the SOT-23 package, significantly simplifying circuit board design and reducing overall component count.
Key Features & Benefits
- Integrated Bias Resistors: Features built-in base input (R1: 2.2kΩ) and base-emitter (R2: 10kΩ) resistors, eliminating the need for external discrete components.
- Simplified Design: Streamlines circuit design and layout, saving valuable PCB space.
- Reduced Assembly Costs: Lowers pick-and-place costs by decreasing the total number of parts required on the board.
- Tight Tolerance: Offers a precise ±10% resistor ratio tolerance for consistent and reliable performance.
- Robust Specification: Capable of handling a maximum collector-emitter voltage (VCE) of 50V and a continuous collector current of 500mA, with a minimum DC current gain (hFE) of 70.
Ideal for a wide range of applications, including industrial control systems, automotive electronics, and power management circuits, where reliability and space savings are critical. Its 7X marking code ensures easy identification, and it is complemented by the PNP-type PDTB123YT for design flexibility. The device has a maximum power dissipation of 250mW and can operate at temperatures up to 150°C, making it suitable for demanding environments.
This surface-mount component is supplied on tape and reel for automated production, offering a practical and cost-effective solution for modern electronic designs that demand high integration and reliability.
