Description
9916H is 18V, 35A, N-channel enhancement mode Power MOSFET. An N-channel enhancement mode Power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of MOSFET that is commonly used in electronic circuits for switching and amplification. It is called an enhancement mode MOSFET because its operation is enhanced by the presence of an external voltage.
The Advanced Power MOSFETs from APEC provide the designer with the best combination of fast switching, ruggedized device design, ultra low on-resistance and cost-effectiveness.
Features
1. Low on-resistance
2. Capable of 2.5V gate drive
3. Low drive current 4. Single Drive Requirement
