1N457/A www.BDTIC.com/FAIRCHILD 1N457/A DO-35 Color Band Denotes Cathode BDTIC Small Signal Diode Absolute Maximum Ratings* Symbol TA = 25°C unless otherwise noted Value Units VRRM Maximum Repetitive Reverse Voltage Parameter 70 V IF(AV) Average Rectified Forward Current 200 mA IFSM Tstg Non-repetitive Peak Forward Surge Current Pulse Width = 1.0 second Pulse Width = 1.0 microsecond Storage Temperature Range 1.0 4.0 -65 to +200 A A °C TJ Operating Junction Temperature 175 °C Value Units *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.
