Note 1 The continuous inverse operating voltage rating, V
operated at elevated junction temperature. The percent derating of V
perature increment above 25°C is equal to V
/10. For critical high temperature–high volt-

age applications, is recommended that diodes be 100% tested and specified at the elevated
temperature.
Note 2 The peak operating current is generally the controlling factor in AC rectifier service and may
be exceeded for pulses of less than 200µs duration.
