Order 1N32__R for stud anode (reverse polarity) types. Ratings and specifications are for frequencies from 50 up to 400 cycles/second, except where noted differently. Rating assumes a rectifier diode heat sink dissipation of 2.0C/watt, or less. Rating assumes a rectifier diode heat sink dissipation of 1.0C/watt, or less. Use of a silicone grease (G-E #G623) between the rectifier base and heat sink is recommended. *Indicates JEDEC Registration Parameters. 232 INSTANTANEOUS FORWARD CURRENT - AMPERES MAXIMUM ALLOWABLE CASE TEMPERATURE - C PEAK FORWARD CURRENT - AMPERES 10,000 190 180 170 iso 140 (30 20 0 100, 2000 {600 200 800 400 Ty= 190C 2 Ty#25C 4 5 INSTANTANEOUS FORWARD VOLTAGE VOLTS 1, MAXIMUM FORWARD CHARACTERISTICS AVERAGE FORWARD POWER DISSIPATION - WATTS N SN 60 AVERAGE FORWARD CURRENT AMPERES 3.
