These diodes are made in batches at the factory, many actually come out at the highest rated voltage but are only printed at the voltage requested by the customer at the time of purchase. This means that many marked diodes actually function at a higher rated voltage and can be used at that higher rating.
Diodes in this particular batch have been printed as W0508RBA040, and W0508RBA060, but are actually rated and certified/tested as 1400V making them equivalent to a W0508RBA140. The original labelling has been left intact to authenticate the Westcode manufacturing.
These diodes have been independently tested using a Tektronix 576 Curve Tracer to verify the higher rated voltage (Vrrrm) from that marked on the body of the diode. We will provide a FOC Certificate of Conformity to verify these test results on purchase of these devices.
W0608RBA140 was SW14HXR300 can be used as W0508RBA120 was SW12HXR300; W0508RBA100 was SW10HXR300; W0508RBA080 was SW08HXR300; W0508RBA060 was SW06HXR300; W0508RBA040 was SW04HXR300; W0508RBA020 was SW02HXR300 as mechanically equivalent and electrically superior to all the above.
