3EZ Series

      3EZ Series are silicon zener diodes.Here you can get some information about the features.The first one is that the complete voltage range is from 3.9 to 400 Volts.Secondly,it has high peak reverse power dissipation.Thirdly,it has high reliability.Fourthly,it has low leakage current.
      The following is about the mechanical data of 3EZ Series. The case is made of DO-41 Molded plastic.The epoxy is UL94V-O rate flame retardant.Axial lead is solderable per MIL-STD-202,method 208 guaranteed.Color band denotes cathode end.Besides,the mounting position is not limited.The weight is 0.339 gram.
      You have to understand the maximum ratings if you are interested in the product.3EZ Series has five maximum ratings as follows at 25 °C ambient temperature.The DC power dissipation at T_L = 75 °C (P_D) is 3.0 Watts(T_L = Lead temperature at 3/8 " (9.5mm) from body).The maximum forward voltage at I_F = 200 mA  (V_F) is 1.5 Volts.
The maximum thermal resistance junction to ambient air (R^_JA) is 60 K/W.The junction temperature range (T_J) is from - 55 to + 175 °C.The storage temperature range (T_s) is from - 55 to + 175 °C
