Description
D443-800 is a rectifying diode in disc design. It has a repetitive peak reverse voltage VRRM of 3800-4400 V and low static losses. Mean forward current IFAV is 800А. Industry standard design enables easy installation into existing equipment. Maximal junction temperature Tjmax is 150 °C. Diameter of the contact surface is 34 mm.

Rectifying diodes are one of the most widespread types of power switches. They are designed for use in AC/DC systems up to 500 Hz in general purpose electric devices. Anode and cathode are flat bases. Polarity of the diode is marked by a polarity symbol on its housing. The devices have a sealed housing insulating the semiconductor element from environment.

Rectifying diodes by Proton-Electrotex have the following features:
∙ high resistance to electric and thermal cycling;
∙ low static and dynamic losses;
∙ high reliability means minimal equipment downtime;
∙ optimized for industrial use.

At the customer's request Proton-Electrotex is able to select the optimal power diode for given operation modes. It is also possible to ship ready-to-use power semiconductors in assembly with heatsinks.
