* JEDEC registered data for 1N3016B thru 3051B equivalents except reverse (leakage) currents IR are lower and maximum Zener current IZM is higher.
** When applicable, add MQ, MX, MV, MSP prefix for 1N3016B to 1N3051B screening options in accordance with MIL-PRF-19500/115.
† Not JEDEC Data.
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
thermal equilibrium in 25oC 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.
