DPG80C400HB fast recovery diode, current 80A, voltage 400V, fast recovery time 45ns, standard TO-247 package. Soft recovery characteristics, short reverse recovery time, improved thermal performance, and high reliability. Can be used in rectifiers, switching power supplies, etc.

The fast recovery diode is similar to the PN junction of the general diode structure, but its N region near the PN junction has a low impurity concentration and a narrow width, but the P region and N region on both sides of it have a high impurity concentration. The PIN structure of the fast recovery diode. When the fast recovery diode is working in the forward direction, it is actually represented by a short circuit with a very low impedance, but it is actually represented by a high capacitive reactance when it is working anyway. Therefore, fast recovery diodes have higher switching speeds, so they can be used to form generators with very short pulses.

Fast recovery diodes are widely used in pulse width modulators, AC motor inverters, uninterruptible power supplies, switching power supplies, high-frequency heating and other devices and equipment. In these applications, it is nothing more than using its high frequency, high current rectification, freewheeling, high voltage and protection functions.
