600 V Housingless Welding Diode Housingless Welding Diode 600 V, 5.8 kA*/ 6.5 kA ** with a diameter of 38 mm. Designed with improved losses for medium frequency resistance welding and high current rectifier applications. The low on-state voltage allows very high forward current of around 5.8 kA continuously. The 38DN06B02 is mechanically compatible to 38DN06 and very compact with a diameter of 38 mm and a height of 4 mm. *IFAV @ Tc= 100°C **IFAV @ Tc= 85°C
