TOLERANCE AND TYPE NUMBER DESIGNATION The type numbers listed indicate a tolerance of ±5%. 3. ZENER VOLTAGE (VZ) MEASUREMENT Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature at 25°C. 4. ZENER IMPEDANCE (ZZ) DERIVATION 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 = 60 Hz. *Include SZ-prefix devices where applicable. www.onsemi.com 3 1SMB59xxBT3G Series, SZ1SMB59xxT3G Series P D, MAXIMUM POWER DISSIPATION (WATTS) 6 PPK , PEAK SURGE POWER (WATTS) 1K 5 4 TL 3 2 1 TA 0 0 25 50 75 100 T, TEMPERATURE (°C) 125 RECTANGULAR NONREPETITIVE WAVEFORM TJ=25°C PRIOR TO INITIAL PULSE 500 300 200 100 50 30 20 10 0.1 150 0.2 0.3 0.5 10 8 VZ @ IZT 6 4 2 0 -2 -4 2 4 6 8 VZ, ZENER VOLTAGE (VOLTS) 10 12 VZ @ IZT 100 70 50 30 20 10 10 20 30 50 70 100 VZ, ZENER VOLTAGE (VOLTS) 200 Figure 4.
