Exchange of Thyristors for Size D6 
3ADW000195R0501 DCS800 Service Manual e e
Disk type thyristors 
  Some converter modules size D6 are equipped with different disc type thyristors. 
For easy identification the name plate of the converter module is marked with “a” 
after the voltage identification:

Parts list 
 
  The current and voltage ratings of original and second thyristor type are the same, 
but the sizes of gate and cathode terminals are different. Thus it is not possible to 
interchange both thyristor types as spares. 
 
 
Attention: Use always the correct spare thyristor!
