This well-established Zener diode series for the 1N3016 thru 1N3051JEDEC 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 datasheet). Microchip also offers numerous other Zener diode products for a variety of other packages including surface mount.
