Note 1. A Transient Suppressor is usually selected according to the "Reverse Stand Off Voltage (VR)" which should be equal to or greater than the DC or continuous peak operating voltage level.
Note 2. Steady State Power Dissipation is 5 Watts. Forward Surge Current is 200 Amps.
Storage & Operating Temperature Range is -65°C to +175°C.
