The COE of the MountingSurface System Should Be Selected ToProvide A Suitable Match With ThisDevice.NOTE 1No Suffix type numbers are +20% with guaranteed limits for only VZ, lR, and VF. Units with “A” suffix are +10% with guaranteed limits for VZ, lR, 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%. Zener voltage is measured with the device junction in thermal equilibrium at an ambienttemperature of 25°C +3°C. Zener impedance is derived by superimposing on 1ZTA 60Hz rms a.c. current equal to 10% of1ZT.NOTE 2NOTE 3NOTE 4NOTE 5Reverse leakage currents are measured at VRas shown on the table.∆VZis the maximum difference between VZat lZTand VZat lZLmeasured with the device junction in thermal equilibrium.6 LAKE STREET, LAWRENCE, MASSACHUSETTS01841PHONE (978) 620-2600FAX (978) 6-0803WEBSITE: http://www.microsemi.com143元器件交易网www.cecb2b.com)SMHO(TZZ ECNADEPMI RENEZ144CDLL5518 thruCDLL56DFIGURE 2r)ewW500omP(400 dneoi300ttaaRpi ,s200disPD10000255075100125150175TEC , End cap temperature (C°)POWER DERATING CURVE1000500400300200100504028 VOLT30201011 VOLT326.8 VOLT1.1 .2 .5 1 2 5 10 20 50 100OPERATING CURRENT IZT(mA)FIGURE 3ZENER IMPEDANCE VS.
