Indicates peak inverse voltage (PIV).
For supply voltage 110 volts to 415 volts replace with “16”
For supply voltage 525 volts replace with “18”
Note
: 16 = 1600 volt
18 = 1800 volt
Note
The Thyristors listed will in all cases be suitable as spares but installed thyristors may not necessary be
the same.
