Infineon IRFP4321PBF N-Channel Power MOSFET 78A 150V TO-247AC
Infineon IRFP4321PBF 78A, 150V N-Channel MOSFET in TO-247AC package. Low RDS(ON) for high-efficiency power management & industrial use.
The Infineon IRFP4321PBF is a high-performance HEXFET® N-channel power MOSFET, engineered to deliver superior efficiency and reliability in demanding electronic applications. It features improved diode recovery characteristics, which significantly enhance switching performance and reduce electromagnetic interference (EMI), making it an excellent choice for noise-sensitive designs.
This component is ideally suited for high-efficiency synchronous rectification in switch-mode power supplies (SMPS), as well as hard-switched and high-frequency circuits. Its low on-state resistance (RDS(ON)) minimises conduction losses, while the low gate charge contributes to faster switching speeds and improved overall system efficiency. The device also boasts a fully characterised avalanche safe operating area (SOA) and a robust 30V gate voltage rating, increasing its durability and reliability under stressful operating conditions.
