D056-9500 is a welding diode in housingless disc design. It has a repetitive peak reverse voltage VRRM of 200-400 V and low static losses. Industry standard design enables easy installation into existing equipment. Maximal junction temperature Tjmax is 180 °C. Diameter of the contact surface is 50 mm.
An advantage of housingless welding diodes is the absence of a ceramic housing, reducing their weight and dimensions. Besides, lower amount of contact surfaces results in lower thermal resistance allowing these devices conduct high currents even at significant temperature changes.
“D0” series of welding diodes by Nimatek Technology 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.
At the customer’s request Nimatek Technology 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.
