DESCRIPTION
APPEARANCE
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 available 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.
