* 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 25
oC still air. The test currents (I
ZT) 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.
