Fast Recovery Diodes Dynex Replacement
Fast Recovery Diodes, also known as Fast Diodes or Fast Switching Diodes in disc design are semiconductor devices with a short reverse recovery time.
Fast Recovery Diodes ADF, ADSF JY ENERGITM are a replacement, analog, alternative semiconductor devices for Fast Recovery Diodes DF, DSF Series Dynex Semiconductor.
The fast recovery diodes converting DC and AC currents up to 3200A in circuits with voltages up to 6000V. Their main applications are for DC-DC converters and inverters, induction heating, high-frequency rectifiers, switching power supplies. Features: 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. The diode has an industry standard ceramic housing making it easy to integrate the device into existing equipment.
This diode has a disc housing with pressure contacts. The polarity of the diode (anode, cathode) is determined by the icon on the case. The technical specifications, part numbering guide, datashets for diodes are listed below.
Rectifier Diodes JY ENERGITM have the following features: low static and dynamic losses, high values of VRSM/VRRM, 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.
Our company provides a quality guarantee for rectifier diodes of 2 years from the date of purchase. When supplying diodes, if necessary, we provide technical passport and certificate of conformity.
The final price of fast recovery diodes depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
