1 / 2 page 1N457/A, Rev. A 1N457/A Small Signal Diode Absolute Maximum Ratings* T A = 25°C unless otherwise noted *These ratings are limiting values above which the serviceability of any semiconductor device may be impaired. NOTES: 1) These ratings are based on a maximum junction temperature of 200 degrees C. 2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
