Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Ratings at 25°C ambient temperature unless otherwise specified.
2. Derate by 20% for capacitive loads.
†Indicates JEDEC Registered Data for 1N4933 Series.
