Home

Using ground-breaking new silicon technology, Westcode has launched a new Welding Diode that offers a low voltage rating of 200V. The new 8mm thick, 44.4mm pole face diameter diode is a fully hermetic, press-pack ceramic walled package and is mechanically compatible with industry standard outlines. Samples and data sheet for the first 200V device, W7023DB200, are available now with new larger 200V and 400V versions currently in development.
