Type and meanings



1. M for Module
2. Letter code for subtype of module (D: rectifier diode Z: fast recovery diode T: phase control thyristor K: fast 
    turn-off thyristor F: D+T H: Z+K U: ultra fast and soft recovery diode)
3. Circuit (A: common anode C: in series K: common cathode X: anti-parallel Q: single phase bridge G: three
    phase common anode S: three phase bridge Y: three phase common cathode R: in paraller)
4. Average current
5. Class according to V_DRM,V_RRM

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.
