Notes :
(1) A transient suppressor is normally selected according to the Working Peak Reverse Voltage (VRWM) which should be equal to or
greater than the DC or continuous peak operating voltage level.
(2) VBR measured at pulse test current I
T at ambient temperature of 25 °C.
(3) Surge current waveform per Fig. 2 and derate per Fig. 5.
