†
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1 The notation 10/1000 refers to a waveshape having tr = 10 µs and tw = 1000 µs ending at 50% of the peak value. The notation 10/160
is tr = 10 µs and tw = 160 µs. The notation 2/10 is tr = 2 µs and tw = 10 µs.
2. This value applies when the case temperature is at or below 85°C. The surge current may be repeated after the device has returned
to thermal equilibrium.
