The type numbers shown have a standard tolerance of 5% on the nominal Zener voltage. 4. Nominal Zener voltage is measured with the device junction in thermal equilibrium at TL = 30C 1C. 5. ZZT and ZZK are measured by dividing the AC voltage drop across the device by the ac current applied. The specified limits are for IZ(AC) = 0.1 IZ(dc) with the AC frequency = 1 KHz. http://onsemi.com 3 MMSZ5221BT1 Series VZ, TEMPERATURE COEFFICIENT (mV/C) VZ, TEMPERATURE COEFFICIENT (mV/C) TYPICAL CHARACTERISTICS 8 100 7 TYPICAL TC VALUES FOR MMSZ5221BT1 SERIES 6 5 4 VZ @ IZT 3 2 1 0 -1 -2 -3 2 3 4 5 6 7 8 9 10 VZ, NOMINAL ZENER VOLTAGE (V) 11 12 TYPICAL TC VALUES FOR MMSZ5221BT1 SERIES VZ @ IZT 10 1 10 100 VZ, NOMINAL ZENER VOLTAGE (V) Figure 1.
