FR804 Description

Short technical summary and product information.

The FR804 is a fast recovery rectifier diode manufactured by Diodes Incorporated. It is designed for general purpose rectification and high-frequency switching applications requiring fast reverse recovery. With a maximum repetitive peak reverse voltage (VRRM) of 400V and an average forward rectified current of 8A, it suits moderate power levels.

 

The diode offers a maximum forward voltage of 1.3V at 8A and a fast reverse recovery time (trr) of 250ns, enabling efficient switching. Its peak forward surge current (IFSM) is 150A, ensuring robustness during transient conditions. The operating junction temperature range is -65°C to +175°C.

 

The FR804 is packaged in a TO-220AC through-hole case with plated axial leads, solderable per MIL-STD-202. The package is UL 94V-0 rated for flammability. The device is RoHS3 compliant and REACH unaffected.

 

Typical applications include power supplies, inverters, and freewheeling diodes in inductive loads. The diode's fast recovery characteristics minimize switching losses, making it suitable for high-frequency rectification.
