Description

This well established zener diode series for the 1N3821 thru 1N3830A JEDEC registration in the glass hermetic sealed DO-13 package provides a low voltage selection for 3.3 to 7.5 volts.  It is also well suited for high-reliability applications where it is available in JAN, JANTX, and JANTXV military qualifications.  Higher voltages are also availablA in the 1N3016 thru 1N3051 series (6.8 V to 200 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.
