The INFINEON IRFR540ZPBF (marking code FR540Z) is a high-performance HEXFET® single N-channel Power MOSFET designed for high efficiency and extreme reliability. Utilising advanced processing techniques, this surface-mount (SMD) transistor achieves an exceptionally low ON-resistance per silicon area, minimising power loss in demanding circuits.

Engineered for durability, it features a rugged 175℃ operating junction temperature, ultra-fast switching speeds, and an improved repetitive avalanche rating. Whether you are replacing a faulty component or designing a new power supply module, the IRFR540Z delivers the robust performance required for modern electronics.

Key Features & Benefits

  • Advanced HEXFET® Technology: Optimised for ultra-low on-resistance to maximise energy efficiency.
  • High-Temperature Resilience: Operates reliably up to a 175℃ junction temperature, ideal for high-heat environments.
  • Fast Switching Speed: Reduces switching losses in high-frequency applications.
  • Improved Avalanche Rating: Enhanced ruggedness against voltage spikes and inductive load energy.
  • Compact SMD Package: Housed in a standard TO-252 (D-Pak) casing for efficient automated PCB assembly.
