Surface mount equivalent to JEDEC registered
1N5518 thru 1N5546 series
Internal metallurgical bond with the 鈥?1鈥?suffix
Also available in JAN, JANTX, and JANTXV
qualifications per MIL-PRF-19500/437 by adding
the JAN, JANTX, or JANTXV prefixes to part
numbers for desired level of screening; (e.g.
JANTX1N4099UR-1, JANTXV1N4109CUR-1, etc.)
Nonbonded types also available without the 鈥?1鈥?/div>
suffix for both the axial and surface mount
packages
DO-7 or DO-35 glass body axial-leaded Zener
equivalents also available per JEDEC registration
with part numbers 1N5518 thru 1N5546 on
separate data sheets
