TOLERANCE AND VOLTAGE DESIGNATION – The JEDEC type numbers shown without a suffix letter prior to the UR are +/-20% with guaranteed limits for only VZ, IR, and VF. Units with A suffix prior to the UR are +/-10% with guaranteed limits for VZ, IR, and VF. Units with guaranteed limits for all six parameters are indicated by a B suffix for +/-5.0% units, C suffix for +/-2.0% and D suffix for +/-1.0% prior to the UR. 2. ZENER VOLTAGE (VZ) MEASUREMENT – Nominal zener voltage is measured with the device junction in thermal equilibrium with ambient temperature of 25 oC. 3. ZENER IMPEDANCE (ZZ) MEASUREMENT – The zener impedance is derived from the 60 Hz ac voltage, which results when an ac current having an rms value equal to 10% of the dc zener current (IZT) is superimposed on IZT. 4. REVERSE CURRENT (IR) – Reverse currents are guaranteed and are measured at VR as shown on the table. 5. MAXIMUM REGULATOR CURRENT (IZM) – The maximum current shown is as shown in MIL-PRF-19500/437. 6. MAXIMUM REGULATION FACTOR ( ∆VZ) – ∆VZ is the maximum difference between VZ at IZT and VZ at IZL measured with the device junction in thermal equilibrium. 7. PART NUMBER – These may be ordered as either 1N5518UR thru 1N5546UR or as MLL5518 thru MLL5546 part numbers. For JAN, JANTX, or JANTXV military types, see separate data sheet for the 1N5518UR-1 thru 1N5546UR-1 part numbers. Microsemi Scottsdale Division 8700 E. Thomas Rd.
