Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be attached. http://www.luguang.cn mail:[email protected] 1SMB5926-1SMB5956 3.0W Surface Mount Silicon Zener Diode ELECTRICAL CHARACTERISTICS (TA=25OC unless otherwise noted) Device (Note 1) 1SMB5926 1SMB5927 1SMB5928 1SMB5929 1SMB5930 1SMB5931 1SMB5932 1SMB5933 1SMB5934 1SMB5935 1SMB5936 1SMB5937 1SMB5938 1SMB5939 1SMB5940 1SMB5941 1SMB5942 1SMB5943 1SMB5944 1SMB5945 1SMB5946 1SMB5947 1SMB5948 1SMB5949 1SMB5950 1SMB5951 1SMB5952 1SMB5953 1SMB5954 1SMB5955 1SMB5956 Device Zener Voltage Range (Note 2) Marking Vz @ Izt IZT Code Nom (V) Min (V) Max (V) mA 926B 11 10.45 11.55 34.1 927B 12 11.4 12.6 31.2 928B 13 12.35 13.65 28.8 929B 15 14.25 15.75 25.0 930B 16 15.2 16.8 23.4 931B 18 17.1 18.9 20.8 932B 20 19 21 18.7 933B 22 20.9 23.1 17.0 934B 24 22.8 25.2 15.6 935B 27 25.65 28.35 13.9 936B 30 28.5 31.5 12.5 937B 33 31.35 34.65 11.4 938B 36 34.2 37.8 10.4 939B 39 37.05 40.95 9.6 940B 43 40.85 45.15 8.7 941B 47 44.65 49.35 8.0 942B 51 48.45 53.55 7.3 943B 56 53.2 58.8 6.7 944B 62 58.9 65.1 6.0 945B 68 64.6 71.4 5.5 946B 75 71.25 78.75 5.0 947B 82 77.9 86.1 4.6 948B 91 6.45 95.55 4.1 949B 100 95 105 3.7 950B 110 1.4.5 11505 3.4 951B 120 114 126 3.1 952B 130 123.5 136.5 2.9 953B 150 142.5 157.5 2.5 954B 160 152 168 2.3 955B 180 171 189 2.1 956B 200 190 210 1.9 Zener Impedance (Note 3) Leakage Current IZM ZZT @ IZT ZZK @ IZK Ohms Ohms mA 5.5 550 0.25 6.5 550 0.25 7 550 0.25 9 600 0.25 10 600 0.25 12 650 0.25 14 650 0.25 17.5 650 0.25 19 700 0.25 23 700 0.25 28 750 0.25 33 800 0.25 38 850 0.25 45 900 0.25 53 950 0.25 67 1000 0.25 70 1100 0.25 86 1300 0.25 100 1500 0.25 120 1700 0.25 140 2000 0.25 160 2500 0.25 200 3000 0.25 250 3100 0.25 300 4000 0.25 380 4500 0.25 450 5000 0.25 600 6000 0.25 700 6500 0.25 900 7000 0.25 1200 8000 0.25 IR uA 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 1.0 1.0 1.0 1.0 1.0 1.0 VR V 8.4 9.1 9.9 11.4 12.2 13.7 15.2 16.7 18.2 20.6 22.8 25.1 27.4 29.7 32.7 35.8 38.8 42.6 47.1 51.7 56.0 62.2 69.2 76.0 83.6 91.2 98.8 114.0 121.6 137 152 IZTC mA(dc) 136 125 115 100 93 83 75 66 62 55 50 45 41 38 34 31 29 26 24 22 20 18 16 15 13 12 11 10 9 8 7 Notes: 1. Tolerance and type number designation the type numbers listed indicate a tolerance of ±5%. 2. Zener voltage (VZ) measurement Nominal Zener voltage is measured with the device junction in thermal equilibrium with ambient temperature at 25oC. 3. 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. http://www.luguang.cn mail:[email protected] PD, MAXIMUM POWER DISSIPATION (WATTS) OVZ, TEMPERATURE COEFFICIENT (mV/oC) 1SMB5926-1SMB5956 3.0W Surface Mount Silicon Zener Diode RATINGS AND CHARACTERISTIC CURVES (1SMB5926 THRU 1SMB5956) FIG.1- STEADY STATE POWER DERATING 6 5 4 TL 3 2 1 TA 0 0 25 50 75 100 125 T, TEMPERATURE(oC) FIG.3- ZENER VOLTAGE - TO 12 VOLTAGES 10 8 VZ @ IZT 6 4 2 0 -2 -4 2 4 6 8 10 VZ, ZENER VOLTAGE (VOLTS) 150 12 FIG.5- VZ = 3.3 THRU 10 VOLTS 100 OVZ, TEMPERATURE COEFFICIENT (mV/oC) PPK, PEAK SURGE POWER (WATTS) FIG.2- MAXIMUM SURGE POWER 1000 500 300 200 100 50 30 20 10 0.1 0.2 0.5 1 2 5 10 20 PW, PULSE WIDTH (ms) 50 100 FIG.4- ZENER VOLTAGE - 14 TO 200 VOLTAGES 200 VZ @ IZT 100 70 50 30 20 10 10 20 30 50 70 100 VZ, ZENER VOLTAGE (VOLTS) FIG.6- VZ = 12 THRU 82 VOLTS 100 200 IZ, ZENER CURRENT (mA) 10 10 11 0.1 0 1 2 3 4 5 6 7 8 9 10 VZ, ZENER VOLTAGE .
