Electrical Characteristics (Cont’d):
Clamping Factor: 1.33 @ full rated power
1.20 @ 50% rated power
The clamping factor is defined as: The ratio of the actual V
C
(Clamping voltage) to the actual BV
(Breakdown Voltage) as measured on a specific device.

off voltage
(V
WM
) and should be equal or greater than DC or continuous peak operating voltage.
