B2 January 2007 1N/FDLL 914/A/B / 916/A/B / 4148 / 4448 Small Signal Diode Absolute Maximum Ratings* T a=25°C unless otherwise noted * 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 state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations. Thermal Characteristics Symbol Parameter Value Units VRRM Maximum Repetitive Reverse Voltage 100 V IO Average Rectified Forward Current 200 mA IF DC Forward Current 300 mA if Recurrent Peak Forward Current 400 mA IFSM Non-repetitive Peak Forward Surge Current Pulse Width = 1.0 second Pulse Width = 1.0 microsecond 1.0 4.0 A A TSTG Storage Temperature Range -65 to + 175 °C TJ Operating Junction Tempera -65 to + 175 °C Symbol Parameter Max.
