- Description
D063-11500 is a welding diode in disc design. It has a repetitive peak reverse voltage VRRM of 200-400 V and low static losses. Mean forward current IFAV equals 11500 A. Industry standard design enables easy installation into existing equipment. Maximal junction temperature Tjmax is 180 °C. Diameter of the contact surface is 57 mm.
"D0" series of welding diodes by Proton-Electrotex has the following features:
∙ ability to conduct high mean forward current, allowing to reduce the amount of parallel devices
∙ high resistance to electric and thermal cycling ensures a long service life;
∙ minimal static losses;
∙ high maximal junction temperature (Tjmax) allows these diodes to conduct higher current with the same cooling system;
∙ possibility of double-sided cooling;
∙ optimized for high current rectifiers;
∙ very low thermal resistance;
∙ designed for medium-frequency welding equipment.

- Applications
Welding diodes are mostly used in contact welding machines. Operation in welding machines is characterized by short impulses of current causing the semiconductor structure to heat and then cool down, as a result of limitations of welding machine duty cycle (modes "operation - cooling"). As a result, the semiconductor is exposed to frequent cyclical thermal and mechanical stress. All this imposes harsh requirements to static and dynamic properties of the devices.
