Description
The Advanced Power MOSFETs from APEC provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and costeffectiveness.
4501GSD is N and P-Channel Power MOSFET. N-channel and P-channel power MOSFETs are types of metal-oxide-semiconductor field-effect transistors designed to handle high power levels in electronic circuits. They are commonly used in various applications such as power supplies, motor drives, amplifiers, and switching circuits.
Features
1. Simple Drive Requirement
2. Low On-resistance
3. Fast Switching Characteristic
