FR604 6 A 400 V Fast-Recovery Rectifier Diode

FR604 is a 6 A, 400 V fast-recovery rectifier diode in an axial through-hole package. It is used for rectification where faster reverse recovery is required in circuits designed for its voltage, current and thermal limits.Key specifications Parameter Specification Part number FR604 Device type Fast-Recovery Rectifier Diode Average forward rectified current 6 A under specified datasheet conditions Repetitive peak reverse voltage (VRRM) 400 V Package R-6 axial Mounting / terminals Through hole / 2 axial leads Polarity marking Band identifies cathode Recovery class Fast recovery Typical applications Rectification in appropriately designed switching circuits Power conversion and industrial electronic repair Replacement in circuits specifying FR604 recovery characteristics Selection notesThe reverse-voltage rating is a blocking limit, not a regulated output voltage. Check forward-voltage loss, surge current, ambient temperature, mounting and load waveform. Apply the manufacturer's thermal derating; do not assume the headline current is available under every mounting condition.Frequently asked questionsWhat is FR604?FR604 is a fast-recovery rectifier diode rated for 6 A average forward current and 400 V repetitive peak reverse voltage under its datasheet conditions.How does FR604 differ from P600G?Both have a 6 A, 400 V rating in the referenced specifications, but FR604 is a fast-recovery rectifier and P600G is a standard rectifier. Recovery behaviour matters in switching applications.Which end of FR604 is the cathode?The banded end is the cathode. The opposite end is the anode. Match the orientation to the PCB marking or schematic.Can FR604 replace another diode?Check the full part number, reverse voltage, average and surge current, recovery behaviour, package and thermal limits before substitution. Matching only the physical size is insufficient.Buying from Anu ElectronicsSold by Anu Electronics, Chennai, India.
