1.

10 X 1000 us, non–repetitive

2.

1/2 sine wave (or equivalent square wave), PW = 8.3 ms, duty cycle = 4 pulses per minute maximum

3.

Mounted on minimum recommended pad layout

4.

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.

5.

VBR measured at pulse test current IT at an ambient temperature of 25°C.

6.

Surge current waveform per Figure 1 and derate per Figure 3.
