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.

* JEDEC registered data for 1N3821 thru 3830A equivalents except for lower reverse (leakage) current IR and higher maximum zener current IZM
.
** When applicable, add MQ, MX, or MV prefix to the 1N3821AUR-1 thru 1N3828AUR-1 part numbers for screening options in accordance with MIL-PRF-19500/115.
NOTE 1: Suffix A signifies a +/-5% tolerance on nominal zener voltage. No suffix designates +/-10% tolerance. If tighter tolerance is
required, suffix C is used to identify +/-2%; and suffix D is to identify +/-1% tolerance. VZ is measured with the diode in
thermal equilibrium in 25oC still air. The test currents (IZT) at the listed nominal zener voltages provide a constant 0.25 watts
for this device series per JEDEC registration.
NOTE 2: The zener impedance is derived when a 60 cycle ac current having an rms value equal to 10% of the dc zener current
(IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measured at 2 points to ensure a sharp knee on the
breakdown curve and to eliminate unstable units. See MicroNote 202 for variation in dynamic impedance with different
zener currents.
NOTE 3: This product series has been previously identified as MLL3821 thru MLL3830A by Microsemi. This alternate name
may still be used, however the Industry name of 1N3821UR-1 thru 1N3830UR-1 is preferred.
