Remarks: this part is omitted usually.Its usage is as below: (TD), (DT),(KZ), (ZK) means the sequence ofdevices in thyristor/diode mixedmodules. (NA), (NK), (A), (K) meansthe bottom of non-isolated moduleis the anode and cathode of devices.(N) means the bottom plate ofmodules is common electrode. (AA)means modules are in compliancewith low-voltage standard.
