The Zener Voltage (VZ) is tested under pulse condition of 10ms 2. The device numbers listed have a standard tolerance on the nominal zener voltage of ±5%. 3. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter voltage tolerances, contact your nearest Taiwan semiconductor representative. 4. The zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having an rms value equal to 10% of the DC zener current Version : C11 BZX79C2V0-BZX79C75 500mW,5% Tolerance Zener Diode Small Signal Diode Rating and Sharacteristic Curves 1000 500 Total Capacitance [pF] PD-Power Passipation [mW] 600 400 300 200 f = 1MHz Ta = 25℃ VR = 0V 100 VR = 2V 100 VR = 30V 1 0 40 80 120 160 Temperature [℃ ] 0 200 20 40 VZ - Reverse Voltage [V] Figure 1.
