scope:

This guideline describes different techniques for specifying a Transient Off-state Withstand Voltage Robustness Indicator in datasheets for lateral GaN power conversion devices. This guideline does not convey preferences for any of the specification types presented, nor does the guideline address formatting of datasheets. This guideline does not indicate nor require that the datasheet parameters are used in production tests, nor specify how the values were obtained.

This guideline is not intended to provide a methodology to convert between the different specification types, nor imply any of the robustness indicators in this guideline are used to calculate lifetimes. This guideline is not meant to imply the robustness indicators are for unlimited pulses or cycle-by-cycle transient withstand voltage excursions. This guideline applies only to off-state, and does not apply to other operating modes, such as hard switching, which may place a different type of stress on the device.

However, this guideline does not preclude the specification of a transient withstand voltage for unlimited pulses or cycle-by-cycle. This guideline also does not preclude specifying a transient voltage for other operating modes, such as hard switching or input surge operation. This guideline also does not prevent having a transient voltage parameter on a datasheet which is tied to detailed lifetime and reliability models.
