It is an ideal selection for applications of high density and low parasitic requirements. Due to its glass hermetic qualities, it may also be considered for high reliability applica- tions when required by a source control drawing (SCD).

Also available with suffix C for +2%, and D for 1%, while the absence of a suffix letter denotes + 10% tolerance. NOTE 2: The Zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10% of the DC Zener current (Iz7 or Iz) is superimposed on I7+ or I7x. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and eliminate unstable units. NOTE 3: The reverse surge current is measured at 25C ambient using a 1/2 square wave or equivalent sine wave pulse 1/120 second duration superimposed on I zr. NOTE 4: Voltage measurements to be performed 90 seconds after application of DC current.
