Electrical characteristics of MOSFETs (Static Characteristics IGSS/IDSS/V(BR)DSS/V(BR)DXS)

Gate leakage current (I GSS)

Gate leakage current (I GSS)

The leakage current that occurs when the specified voltage is applied across gate and source with drain and source short-circuited

IGSSmeasurement

Drain cut-off current (I DSS)

Drain cut-off current (I DSS)
The leakage current that occurs when a voltage is applied across drain and source with gate and source short-circuited

IDSSmeasurement

Drain-source breakdown voltage (V (BR)DSS/V (BR)DXS)

Drain-source breakdown voltage (V (BR)DSS/V (BR)DXS)

The maximum voltage that the device is guaranteed to block between drain and source 
V (BR)DSS: With gate and source short-circuited 
V (BR)DSX: With gate and source reverse-biased
