Surface Mount 1.5 W
GLASS ZENER DIODES
SCOTTSDALE DIVISION
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.

NOTE 1: Suffix “B” shown signifies a +/-5% tolerance on nominal zener voltage. No suffix designates a +/-20% and suffix “A” is +/-10%. 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
o
thermal equilibrium in 25 C still air. The test currents (IZT) at nominal voltages provide a constant 0.25 watts for this device series.
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 previously been identified as MLL3016B thru MLL3051B by Microsemi. This alternate name may still be used,
however the Industry name of 1N3016BUR-1 thru 1N3051BUR-1 is preferred.
