BAY73 Small Signal Diode DO-35 Color Band Denotes Cathode Absolute Maximum Ratings * T a Symbol = 25°C unless otherwise noted Parameter Value Unit VRRM Maximum Repetitive Reverse Voltage 125 V IF(AV) Average Rectified Forward Current 500 mA IFSM Non-repetitive Peak Forward Surge Current Pulse Width = 1.0 second Pulse Width = 1.0 microsecond 1.0 4.0 A A -65 to +200 °C 175 °C Value Unit TSTG Storage Temperature Range TJ Operating Junction Temperature * These ratings are limiting values above which the serviceability of the diode may be impaired. NOTES: 1) These ratings are based on a maximum junction temperature of 200 degrees C. 2) These are steady limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
