GSMBZ5221B

      The GSMBZ5221B is designed as zener diodes.
      Some absolute maximum ratings of GSMBZ5221B have been concluded into several points as follow.The first one is about its total device dissipation FR-5 board with condition of Ta=25°C, derate above 25°C which would be 225 mW and would be 1.8 mW/°C.The second one is about its total device dissipation alumina substrate with condition of Ta=25°C, derate above 25°C which would be 300 mW and would be 2.4 mW/°C.The third one is about its thermal resistance junction to ambient which would be 417 °C/W.The last one is about its junction and storage temperature which would have the minimum of -55 °C and the maximum of 150 °C.That are all the ratings.
      Also there are some electrical characteristics of GSMBZ5221B with condition of Vf= 0.9V max @ If= 10mA have been concluded into several points as follow.The first one is about its marking code which would be 18A.The second one is about its test current which would be 20mA.The third one is about its zener voltage which would have the minimum of 2.280V and would have the nominal of 2.4V and would have maximum of 2.520V.The fourth one is about its ZZK with condition of Iz= 0.25mA which would have the maximum of 1200.The fifth one is about its ZZT with condition of Iz=Izt which would have the maximum of 30.The sixth one is about its maximum reverse current which would be 100uA.
      Something should be noted that the GSMBZ5221B is within a series which would be from it to GSMBZ5270B.For example of the type GSMBZ5270B,its marking code which would be 81W.Its test current which would be 1.4mA.GSMBZ5221B's zener voltage which would have the minimum of 86.450V and would have the nominal of 91V and would have maximum of 95.550V.Its ZZK with condition of Iz= 0.25mA which would have the maximum of 2300.Its ZZT with condition of Iz=Izt which would have the maximum of 400.GSMBZ5221B's maximum reverse current which would be 0.1uA.And so on.For more information please contact us.
