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 ±2%. 3. For detailed information on price, availability and delivery of nominal zener voltages between the voltages shown and tighter voltage tolerances, 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 : A11 BZY55B2V4~BZY55B36 500mW,2% Tolerance SMD Zener Diode Small Signal Diode Rating and Sharacteristic Curves FIG 2 Zener Breakdown Characteristics FIG 1 Typical Forward Characteristics 100 Zener Current (mA) Forward Current (mA) 100 10 1 0.1 Ta=25°C 0.01 Ta=25°C 80 60 40 20 0.001 0 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0 4 Forward Voltage (V) 12 16 20 Zener Voltage (V) FIG 4 Admissible Power Disspation Curve FIG 3 Zener Breakdown 50 8 Zener Current (mA) Power Dissipation (mW) 600 40 30 20 10 500 400 300 200 100 0 0 15 20 25 30 35 0 30 60 90 120 150 180 Ambient Tempeture (°C) Zener Voltage (V) FIG 5 Typical Capacitance Capacitance(pF) 200 160 120 Ta=150°C 80 Ta=25°C 40 0 0 5 10 15 20 25 Zener Voltage (V) Version : A11
