Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. Nonrepetitive current pulse per Figure 4 and derated above TA = 25°C per Figure 2.
2. 1/2 sine wave (or equivalent square wave), PW = 8.3 ms, duty cycle = 4 pulses per minute maximum.
*Bidirectional device will not be available in this device

3. Square waveform, PW = 8.3 ms, Non−repetitive duty cycle.
4. 1N5908 is JEDEC registered as a unidirectional device only (no bidirectional option)
5. A transient suppressor is normally selected according to the maximum working peak reverse voltage (VRWM), which should be equal to or
greater than the dc or continuous peak operating voltage level.
6. VBR measured at pulse test current IT at an ambient temperature of 25°C and minimum voltages in VBR are to be controlled.
7. Surge current waveform per Figure 4 and derate per Figure 2 of the General Data − 1500 W at the beginning of this group
