* JEDEC Registered Data
NOTE 1: The JEDEC type numbers shown (B suffix) have a +/-5% tolerance on nominal Zener voltage. The suffix A is used to identify +/-
10% tolerance; suffix C is used to identify +/-2%; and suffix D is used to identify +/-1% tolerance; no suffix indicates +/-20%
tolerance.
NOTE 2: Zener voltage (
VZ) is measured after the test current has been applied for 20 +/- 5 seconds. The device shall be suspended by its
leads with the inside edge of the mounting clips between .375” and .500” from the body. Mounting clips shall be maintained at a
temperature of 25 +8/ -2
oC.
NOTE 3: The zener impedance is derived when a 60 cycle ac current having an rms value equal to 10% of the dc zener current (IZT or
IZK) is superimposed on IZT or IZK. Zener impedance is measured at 2 points to ensure a sharp knee on the breakdown curve
and to eliminate unstable units. See MicroNote 202 for variation in dynamic impedance with different zener currents.
NOTE 4: The values of
IZM are calculated for a +/- 5% tolerance on nominal zener voltage. Allowance has been made for the rise in zener
voltage above VZT which results from zener impedance and the increase in junction temperature as power dissipation approaches
400 mW. In the case of individual diodes IZM is that value of current which results in a dissipation of 400 mW at 75
oC lead
temperature at 3/8” from body.
NOTE 5: The surge for IZSM is a square wave or equivalent half-sine wave pulse of 1/120 sec. duration.
