Silicon 1N3289-96,R Rectifiers A70S,A70T ATIS,A71T LSS The 1N3289-1N3296 Series is the ultimate in todays High Current Silicon Rectifier field. By taking full advantage of the most advanced semiconductor component manufacturing techniques, General Electric O now offers the industrys first double diffused, all hard solder 100-ampere rectifier in PRV ratings up to 1,200 volts. As a result, circuit designers now receive: Features: DIRECTION OF EASY CONVENTIONAL CURRENT FLOW Freedom from Thermal Fatigue Failure e Higher Surge Current Capabilities e NEMA Overload Ratings Forward and Reverse Polarities CONFORMS TO JEDEC OUTLINE 00-8 RATINGS AND SPECIFICATIONS 1N3289 1N3290 1N3291 1N3292 1N3293 A70S 1N3294 A70T 1N3295 = 1N3296 . : 1N3280R 1N3290R 1N3291R 1N3292R 1N3293R A71S 1N3294R A71T 1N3295R 1N3296R Maximum Allowable Transient Peak Reverse Voltage (non-recurrent, 5 millisecond maximum duration) 300 400 525 650 800 925 1050 1175 1300 1500 volts Maximum Allowable Repetitive Peak Reverse Voltage, Van (rep) 200 300 400 500 600 700 800 900 1000 1200 volts Maximum Allowable RMS Reverse Voltage 140 210 280 350 420 490 560 630 700 840 volts Maximum Allowable DC Blocking Voltage** 200 300 400 500 600 700 800 900 1000 1200 volts Maximum Allowable Average Forward Current (single phase, 130C stud temperature) eee LI amperss __ Maximum Allowable Peak One-Cycle Surge Current (60 cps single-phase basis, non-recurrent) ~< 1600 AMPeT eS emer ere Minimum It Rating (non-recurrent) 4100 amperes-seconds (See Curve 8) _emange Maximum Full Load Voltage Drop (full-cycle average, 130C stud temperature, 100 amperes average single phase) << 0.6 VOLES Maximum Full!

Non-recurrent voltage and current ratings, as contrasted to repetitive ratings, are ratings which apply for occasional or unpredicable overloads. For example, the forward surge current ratings are non-recurrent ratings that are used in fault coordination design work. 234 INSTANTANEOUS FORWARD CURRENT- AMPERES FORWARD POWER DISSIPATION - WATTS DIODE SPECIFICATIONS 1N3289-96, R A70S, A70T A718, A71T 3000 IN3289 IN3291 1000 IN3292 8 IN3293 3 6 A70S g o IN3294 3 A70T a o IN3295 INSTANTANEOUS REVERSE CURRENT - MA 0 5 1.0 LS 20 25 3.0 3.5 Oo 200 400 600 800 1000 1200 1400 1600 INSTANTANEOUS FORWARD VOLTAGE -VOLTS 1.
