- VDS: 250V
- ID: 33A (continuous)
- RDS(on): 85mΩ (max at 10V VGS)
Commonly used in power switching applications like motor drives and inverters.

Manufacturer

The FDP33N25 is an N-channel MOSFET manufactured by Fairchild Semiconductor, a well-known American company specializing in power electronics and semiconductor solutions.
Fairchild Semiconductor, founded in 1957, was a pioneer in transistor technology and later became a key supplier of power management components. It was acquired by ON Semiconductor in 2016, which continues to produce many Fairchild legacy products, including the FDP33N25.
The company was known for high-performance discrete semiconductors, analog ICs, and power solutions used in computing, automotive, and industrial applications. Today, ON Semiconductor maintains Fairchild’s product lines while expanding its own portfolio.

Application

The FDP33N25 is an N-channel MOSFET commonly used in:
1. Power Supplies – Switching regulators, DC-DC converters.
2. Motor Control – Drives for brushed DC and stepper motors.
3. Inverters – Power conversion in UPS and solar inverters.
4. Automotive Systems – Electronic control units (ECUs), lighting.
5. Industrial Equipment – High-efficiency switching applications.
With a 250V drain-source voltage (VDS) and 33A current rating, it suits medium-to-high-power switching tasks requiring low on-resistance (RDS(on)).

Package

The FDP33N25 is a N-channel MOSFET typically available in a TO-220 package. This package type is common for power transistors, offering good thermal performance and ease of mounting. The TO-220 package has three leads and a metal tab for heat dissipation, making it suitable for high-power applications.
