LEADLESS GLASS ZENER DIODES  
DESCRIPTION  
APPEARANCE  
This surface mountable zener diode series is similar to the lower voltage  
1N3821 thru 1N3830 JEDEC registration except it is in a surface mount  
DO-213AB package outline. It is an ideal selection for applications of high  
density and low parasitic requirements. Due to its glass hermetic qualities  
and enhanced metallurgical bonded internal construction, it is also well  
suited for high reliability applications. This can be acquired by a source  
control drawing (SCD), or simply by ordering device types with a MQ, MX  
or MV prefix for equivalent screening to JAN, JANTX or JANTXV  
respectively.
