Fast Recovery Diode FR207 (2A / 1000V) – High-Voltage Rectifier for High-Speed Switching Applications

The FR207 Fast Recovery Diode (2A / 1000V) is a high-performance rectifier diode designed for applications that require fast switching speed, high reverse voltage capability, and reliable current handling. Compared to standard rectifier diodes, the FR207 features a short reverse recovery time, making it ideal for use in switch-mode power supplies (SMPS), inverters, converters, and high-frequency rectification circuits.

With a maximum average forward current of 2 amperes and a peak repetitive reverse voltage of 1000 volts, the FR207 diode provides excellent electrical performance and durability in demanding electronic environments. Its axial-lead package ensures easy installation and compatibility with through-hole PCB designs.

Fast Recovery Performance for High-Frequency Circuits

The defining feature of the FR207 diode is its fast reverse recovery time, which significantly reduces switching losses when compared to standard rectifier diodes such as the 1N540x series. This fast recovery behavior minimizes heat generation and improves overall system efficiency, especially in high-frequency switching applications.

Fast recovery diodes are essential in circuits where rapid switching occurs, as slow recovery diodes can cause excessive power loss, noise, and reduced efficiency.
