1N3821UR-1 thru 1N3830AUR-1, e3 or MLL3821 thru MLL3830A, e3 SCOTTSDALE DIVISION LEADLESS GLASS ZENER DIODES 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. WWW .

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. 1N3821UR-1 thru 1N3830AUR-1,e3 or MLL3821 thru MLL3830A,e3 Copyright © 2006 3-12-2006 REV C Microsemi Scottsdale Division 8700 E.
