This well established zener diode series for the 1N3016 thru 1N3051 
JEDEC registration in the metal case DO-13 package provides a glass 
hermetic seal for 6.8 to 200 volts. It is also well suited for high-reliability 
applications where it is available in JAN, JANTX, and JANTXV military 
qualifications. Lower voltages are also available in the 1N3821 thru 
1N3830 series (3.3 V to 7.5 V) in the same package (see separate data 
sheet). Microsemi also offers numerous other Zener diode products for a 
variety of other packages including surface mount.

2. Zener Voltage ( 
nominal voltages provide a constant 0.25 watts. 
3. The zener impedance is derived when a 60 cycle ac current having an rms value equal to 10% of the dc zener current (I
) is superimposed on IZT or IZK. Zener impedance is measured at 2 points to ensure a sharp knee on the breakdown curve 
I
ZK
and to eliminate unstable units. See MicroNote 202 for variation in dynamic impedance with different zener currents. 
4. These values of I 
voltage end of its tolerance range. Allowance has also been made for the rise in zener voltage above V 
impedance and the increase in junction temperature as a unit approaches thermal equilibrium at a dissipation of 1 watt. The IZM 
values shown for +/-5% tolerance units may be used with little error for +/-10% tolerance units, but should be reduced by 7% to 
include a +/-20% tolerance unit near the high voltage end of its tolerance range.
