avalanchestandardrectifier

Fast Recovery Diode ADF451 AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for fast recovery diode DF451 Dynex Semiconductor. Average forward current IFAV – 295 ampere, repetitive peak reverse voltage VRRM – 1600V. Features of Fast Recovery Diodes: optimised for line frequency; high surge capability; low recovery charge; low reverse recovery time; high switching speed; high reverse voltage and high current handling capabilities. The peculiarity of diodes is their fast recovery (short reverse recovery time trr and small recovery charge) and application at high frequencies. Diodes have a high current-carrying capacity at high frequencies. Their main applications are for DC-DC converters and inverters, induction heating, high-frequency rectifiers, switching power supplies. Air and water heat sinks for diode cooling are also available to order. "Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series" for thyristors and diodes cooling are also available to order. Rectifier Diodes AS ENERGITM have the following features: industry standard housing; low static and dynamic losses, high values of VRRM/VRSM, extensive experience of using the devices in various industries, range of voltages from 100 to 9000 V and amperages from 100 to 7500 A, high resistance to thermal and electric cycling. The technical specifications and parameters of DF451 and replacement ADF451, datasheet PDF, outline drawing and dimensions are listed below. Our company provides a quality guarantee for fast recovery diodes of 2 years from the date of purchase.
