ONSEMI FDPF18N50 N-Channel Power MOSFET, 500V 18A, TO-220F
ONSEMI FDPF18N50 N-Channel MOSFET. 500V, 18A, low Rds(on). For PFC, ATX supplies, lighting ballasts & power management. TO-220F package.
The ONSEMI FDPF18N50 is a high-voltage, N-Channel power MOSFET engineered using advanced UniFET™ planar stripe and DMOS technology. This design is specifically tailored to minimise ON-state resistance (Rds(on)), delivering superior switching performance and enhanced avalanche energy strength for demanding power applications.
A key feature of this device is its 100% avalanche ruggedness testing, ensuring reliable operation under stressful conditions. It boasts a typically low gate charge of 45nC and a low reverse transfer capacitance (Crss) of 25pF, which contribute to reduced switching losses and improved efficiency in high-frequency circuits.
Applications
This MOSFET is ideally suited for a wide range of switching power converter applications, making it a versatile component for modern electronic designs. Its robust performance characteristics make it perfect for:
- Power Factor Correction (PFC) circuits
- Power supplies for Flat Panel Display (FPD) televisions
- ATX computer power supplies
- Electronic lamp ballasts for lighting
- General power management systems
- Consumer electronics
Housed in a industry-standard TO-220F through-hole package, it offers excellent thermal performance and ease of mounting on printed circuit boards (PCBs). With a high maximum operating temperature and significant power dissipation capability, the FDPF18N50 is built for reliability and long-term stability in critical power conversion roles.
