Finish: External Surfaces Corrosion Resistant
Polarity: Cathode Indicated by Band
Max. Ratings:
DC Power Dissipation (@TA=50°C): 1.0W
Derated above 50°C: 6.67mW/°C
Operating & Storage Temperature: -65°C to 200°C
Electrical Characteristics (TA=25°C unless otherwise noted, VF=1.2V max., IF=200mA)
Nominal Zener Voltage: 47V @ 5.5mA nom.
Zener Impedance: 80 ohms @ 5.5mA
Zener Knee Impedance: 1500 ohms @ 0.25mA
(The zener impedance is derived from the 60 cycle ac voltage, which results when an ac current
having an rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed
on IZT or IZK)
Leakage Current: 5µA, 35.8V
Surge Current: 95mA @ TA=25°C
(The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse
surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration
superimposed on the test current, IZT, per JEDEC registration; however, actual device
capability is as described in Figure 5 of the General Data — DO-41 Glass)
