DESCRIPTION
APPEARANCE
This surface mountable zener diode series is similar to the 1N3016 thru
1N3051 JEDEC registration in the DO-13 package except that it meets the
surface mount DO-213AB outline. It is an ideal selection for applications of
high density and low parasitic requirements. Due to its glass hermetic seal
qualities and metallurgically enhanced internal construction, it is also well
suited for high-reliability applications. This can be acquired by a source
control drawing (SCD), or by ordering device types with MQ, MX, or MV
prefix to part number for equivalent screening to JAN, JANTX or JANTXV.
