Microsemi .C OM ELECTRICAL CHARACTERISTICS* *JEDEC Registered Data. The Type Number indicates 5% Tolerance. (See Note 1.) NOTES: 1. 2. 3. Devices listed have a +/-5% voltage tolerance on nominal Vz with a B suffix. An A suffix is +/-10% and no suffix is +/-20%. Suffix C denotes a +/-2% tolerance and suffix D denotes a +/-1% tolerance. All static parameters measured under pulsed conditions, tp = 300 µs. Dynamic Impedance is derived by measuring the ac voltage when superimposing an ac rms current of 0.2 mA at 1000 Hz on to the dc level of IZT. 1N5728B thru 1N5757B-1 Copyright  2003 11-03-2003 REV A Microsemi Scottsdale Division 8700 E.
