IRFB4321PBF

MOSFETs - Single

N-ChannelMOSFET200VTO-220

The IRFB4321PBF is a 200V N-Channel MOSFET in a TO-220 package, optimized for power conversion applications requiring high efficiency and robust thermal performance.

Best for

  • DC-DC power converters
  • UPS DC-AC inverters
  • Motor control circuits

Avoid if

  • Space-constrained designs requiring SMD packages (this is TO-220).
  • Applications requiring extremely low gate charge for ultra-high frequency switching.

Check before use

  • Thermal management requirements.
  • Gate driver capability for 154nC gate charge.
