Tolerance and Type Number Designation. The type numbers listed have a standard tolerance on the nominal zener voltage of ±5%. 2. Specials Available Include: A. Nominal zener voltages between the voltages shown and tighter voltage tolerances. B. Matched sets. 3. Zener Voltage (VZ) Measurement. Guarantees the zener voltage when messured at 90 seconds while o C± 11oC, from the diode body. maintaining the lead temperature (TL) at 30 C± 4. Zener Impedance (ZZ) Derivation. The zener impedance is derived from the 60 cycle ac voltage, which results when an ac current having and rms value equal to 10% of the dc zener current (IZT or IZK) is superimposed on IZT or IZK. 5. Surge Current (Ir) Non-Repetitive. The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current, IZT, per JEDEC registration; however, actual device capability is as described in Figure 10. 08/22/2007 Rev.1.00 www.SiliconStandard.com 2 1SMA4741 thru 1SMA200Z RATINGS ANAD CHARACTERISTIC CURVES (1SMA4741 THRU 1SMA200Z) FIG.2- TYPICAL FORWARD CHARACTERISTICS 1000 1.25 MINIMUM MAXIMUM 500 IF, FORWARD CURRENT (mA) PD, MAXIMUM POWER DISSIPATION (WATTS) FIG.1- POWER TEMPERATURE DERATING CURVE 1.0 0.75 0.50 0.25 200 100 50 20 10 o 70 C o 150 C o 25 C 5 2 o 0 C 1 0 0 20 40 60 80 100 120 140 160 180 0.4 200 0.5 o AMBIENT TEMPERATURE( C) 10000 7000 5000 TJ = 25 C IZ(rms)= 0.1 IZ(dc) f = 1KHz 47V 2000 0.9 1.0 1.1 27V 1000 700 500 0.8V 200 TYPICAL LEAKAGE CURRENT AT 80% OF NOMINAL BREAKDOWN VOLTAGE 100 50 20 10 100 70 50 5 2 1 0.1 0.2 0.5 1 2 5 10 20 50 100 IZ, ZENER CURRENT (mA) FIG.4- EFFECT OF ZENER VOLTAGE ON ZENER IMPEDANCE 1000 700 500 o TJ = 25 C IZ(rms)= 0.1 IZ(dc) f = 1KHz IZ = 1.0mA 200 100 70 50 5.0mA 20 20mA IR, LEAKAGE CURRENT ( A) ZZ, DYNAMIC IMPEDANCE (OHMS) o ZZ, DYNAMIC IMPEDANCE (OHMS) 0.8 FIG.5- TYPICAL LEAKAGE CURRENT 1000 200 0.7 VF, FORWARD VOLTAGE (VOLTS) FIG.3- EFFECT OF ZENER CURRENT ON ZENER IMPEDANCE 500 0.6 20 10 7 5 2 1 0.7 0.5 o +125 C 0.2 0.1 0.07 0.05 0.02 o 0.01 0.007 0.005 10 7 5 +25 C 0.002 2 0.001 1 1 2 3 5 7 10 20 30 50 70 100 3 4 08/22/2007 Rev.1.00 5 6 7 8 9 10 11 12 13 14 15 VZ, NOMINAL ZENER VOLTAGE (VOLTS) IZ, ZENER CURRENT (mA) www.SiliconStandard.com 3 1SMA4741 thru 1SMA200Z RATINGS ANAD CHARACTERISTIC CURVES (1SMA4741 THRU 1SMA200Z) FIG.6- TYPICAL CAPACITANCE versus Vz FIG.7- TEMPERATURE COEFFICIENTS 400 300 OVZ, TEMPERAYURE COEFFICIENT (mV/oC) a-RANGE FOR UNITS TO 12 VOLTS C, CAPACITANCE (pF) 200 0V BIAS 1.0V BIAS 100 10 8 50% OF BREAKDOWN BIAS 4 1 10 100 +12 +10 +8.0 +6.0 +4.0 +2.0 VZ @ IZT RANGE 0 -2.0 -4.0 2 VZ, FORWARD VOLTAGE (VOLTS) 3 4 6 5 7 8 9 10 11 12 VZ, ZENER VOLTAGE (VOLTS) FIG.8- TEMPERATURE COEFFICIENTS FIG.9- EFFECT OF ZENER CURRENT OVZ, TEMPERAYURE COEFFICIENT (mV/oC) b-RANGE FOR UNITS 11 TO 100 VOLTS OVZ, TEMPERAYURE COEFFICIENT (mV/oC) 100 70 50 30 20 VZ @ IZT RANGE 10 7 5 3 2 1 +6.0 VZ @ IZT TJ=25 oC +4.0 +2.0 20mA 0 0.01mA 1.0mA -2.0 NOTE: BELOW 3 VOLTS AND ABOVE a VOLTS CHANGES IN ZENER CURRENT OO NOT AFFECT TEMPERATURE COEFFICIENTS -4.0 3 10 20 30 50 70 4 100 5 6 7 8 VZ, ZENER VOLTAGE (VOLTS) VZ, ZENER VOLTAGE (VOLTS) Ppk, PEAK SURGE POWER IWATTSO FIG.10- MAXIMUM SURGE POWER 100 70 50 0.8V -10V 30 20 5% D 3 11V -9 -RE 1V N PET UTY C ITIV ON- REP E RECTANGULAR WAVEFORM o TJ = 25 C PRIOR TO INITIAL PULSE ETIT IVE YCLE 10% DUTY 10 7 5 NON CYCLE 20% DUTY CYCLE 2 1 0.01 0.02 0.05 0.1 0.2 0.5 1 2 5 10 20 50 100 200 500 1000 PW, PULSE WIDTH (ms) Information furnished by Silicon Standard Corporation is believed to be accurate and reliable.
