DESCRIPTION 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 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 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.

Zener Voltage Range: to 200V Hermetically sealed DO-13 metal package Internally solder-bonded construction. Also available in JAN, JANTX, JANTXV qualifications per MIL-PRF19500/115 by adding the JAN, JANTX, or JANTXV prefixes to part numbers for desired level of screening, e.g. JANTX1N3016B, JANTXV1N3051B, etc. Surface mount also available with 1N3016BUR-1 thru 1N3051BUR-1 series on separate data sheet

When using JEDEC numbers, B suffix signifies +/-5% tolerance on nominal zener voltage. The suffix A is used to identify +/-10% tolerance; no suffix indicates +/-20% tolerance: suffix C is used to identify 2%; and suffix D is used to identify 1% tolerance.

Zener Voltage (VZ) is measured with junction in thermal equilibrium with still air at a temperature 25 C. The test currents (IZT) at nominal voltages provide a constant 0.25 watts. The zener impedance is derived when a 60 cycle ac current having an rms value equal 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. These values of IZM may often be exceeded in the case of individual diodes. The values shown are calculated for a unit at the high voltage end of its tolerance range. Allowance has also been made for the rise in zener voltage above VZT that results from zener 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 7% to include a +/-20% tolerance unit near the high voltage end of its tolerance range.
