Fast Recovery Diode ADSF8045SK AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for fast recovery diode DSF8045SK Dynex Semiconductor. Average forward current IFAV430 ampere, repetitive peak reverse voltage VRRM4500V.

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 DSF8045SK and replacement ADSF8045SK, 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. When supplying diodes, if necessary, we provide technical passport and certificate of conformity.

Heat sinks for power rectifier disc diodes:

Heat sinks (radiators) are used for single- and double-sided cooling of power semiconductor devices in disc design.

Heat sinks of coolers are made of aluminum radiator profiles and do not require additional protective coating when used in various climatic conditions.

Air and water heat sinks for rectifier diode cooling are also available to order.

See for more information about heatsinks: "Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series".
