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 Marking Code BZX79C2V4 BZX79C2V7 BZX79C3V0 BZX79C3V3 BZX79C3V6 BZX79C3V9 BZX79C4V3 BZX79C4V7 BZX79C5V1 BZX79C5V6 BZX79C6V2 BZX79C6V8 BZX79C7V5 BZX79C8V2 BZX79C9V1 BZX79C10 BZX79C11 BZX79C12 BZX79C13 BZX79C15 BZX79C16 BZX79C18 BZX79C20 BZX79C22 BZX79C24 BZX79C27 BZX79C30 BZX79C33 BZX79C36 BZX79C39 BZX79C43 BZX79C47 BZX79C51 BZX79C56 BZX79C62 BZX79C68 BZX79C75 VZ @ IZT (Volt) Min 2.3 2.6 2.9 3.1 3.4 3.7 4.1 4.5 4.8 5.3 5.9 6.5 7.1 7.8 8.6 9.5 10.5 11.4 12.4 14.3 15.2 17.1 19.0 20.9 22.8 25.7 28.5 31.4 34.2 37.1 40.9 44.7 48.5 53.2 58.9 64.6 71.3 Nom 2.4 2.7 3.0 3.3 3.6 3.9 4.3 4.7 5.1 5.6 6.2 6.8 7.5 8.2 9.1 10 11 12 13 15 16 18 20 22 24 27 30 33 36 39 43 47 51 56 62 68 75 Max 2.5 2.8 3.2 3.5 3.8 4.1 4.5 4.9 5.4 5.9 6.5 7.1 7.9 8.6 9.6 10.5 11.6 12.6 13.7 15.8 16.8 18.9 21.0 23.1 25.2 28.4 31.5 34.7 37.8 41.0 45.2 49.4 53.6 58.8 65.1 71.4 78.8 IZT(mA) 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 2 2 2 2 2 2 2 2 2 2.5 2.5 2.5 ZZT @ IZT(Ω) Max 100 100 95 95 90 90 90 80 60 40 10 15 15 15 15 20 20 25 30 30 40 45 55 55 70 80 80 80 90 130 150 170 180 200 215 240 255 IZK(mA) 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 1.0 0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.5 0.5 ZZK @ IZK(Ω) IR @ VR(μA) Max Max 600 600 600 600 600 600 600 500 480 400 150 80 80 80 100 150 150 150 170 200 200 225 225 250 250 300 300 325 350 350 375 375 400 425 1000 1000 1000 100 75 50 25 15 10 5 3 2 1 3 2 1 0.7 0.5 0.2 0.1 0.1 0.1 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 0.05 VR(V) 1.0 1.0 1.0 1.0 1.0 1.0 1.0 2.0 2.0 2.0 4.0 4.0 5.0 5.0 6.0 7.0 8.0 8.0 8.0 10.5 11.2 12.6 14.0 15.4 16.8 18.9 21.0 23.1 25.2 27.3 30.1 32.9 35.7 39.2 43.4 47.6 52.5 Version : B11 BZX79C2V4-BZX79C75 500mW,5% Tolerance Zener Diode Small Signal Diode Rating and Sharacteristic Curves 600 1000 Total Capacitance [pF] f = 1MHz Ta = 25℃ 100 VR = 0V VR = 2V VR = 5V PD-Power Passipation [mW] 500 400 300 200 100 VR = 20V 10 VR = 30V 0 0 40 1 Temperature [℃ ] 80 120 160 200 0 20 40 VZ - Reverse Voltage [V] 60 80 Figure 1.
