- Small Signal Diode 1N4447 Small Signal Diode August 2011 DO-35 Color Band Denotes Cathode Absolute Maximum Ratings- TA = 25°C unless otherwise noted Symbol Parameter Value Units VRRM IF(AV) IFSM Maximum Repetitive Reverse Voltage Average Rectified Forward Current Non-repetitive Peak Forward Surge Current Pulse Width = 1.0 second Pulse Width = 1.0 microsecond 100 200 1.0 4.0 V m A TSTG TJ Storage Temperature Range Operating Junction Temperature -65 to +200 175 °C °C - 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.
