Tolerance and Type Number Designation. The type numbers losted 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 maintaining the lead temperature(T L) at 30℃±1℃, from the diode body 4. Zener Impedance (Zz) Derivation. The zener impedance is derives from the 60 cycle AC voltage, which results when an accurrent having and rms value equal to 10% of the DC zener current (IZT or IZK) is superimposed on I ZT or IZK 5. Surge Current (IR) Non-Repetitive. The rating listd in the electrical chatacteristics table is maximum peak, non-repetitive, reverse surge curren of 1/2 square wave or equivalent sine wave pulse of 1/120 second duration superimposed on the test current, I ZT per JEDEC registration; however, actual device capability is as described in Figure 10 Version:G11 RATINGS AND CHARACTERISTIC CURVES (1SMA4737 THRU 1SMA200Z) FIG. 2 TYPICAL FORWARD CHARACTERISTICS FIG. 1 POWER TEMPERATURE DERATING CURVE PD, MAXIMUM POWER DISSIPATION (WATTS) 1.5 1000 MINIMUM MAXIMUM IF, FORWARD CURRENT (mA) 1.25 1 0.75 0.5 0.25 100 70℃ 150℃ 10 25℃ 0℃ 0 0 25 50 75 100 125 1 150 0.4 AMBIENT TEMPERATURE(℃) 1 1.1 10000 TA=25℃ Iz(rms)=0.1 Iz(dc) f=1KHz TYPICAL LEAKAGE CURRENT AT 80% OF NOMINAL BREAKDOWN VOLTAGE 47V 100 1000 27V 10 100 0.8V 1 0 1 10 100 Iz, ZENER CURRENT (mA) FIG.4 EFFECT OF ZENER VOLTAGE ON ZENER IMPEDANCE 1000 Iz = 1mA 100 TA=25℃ Iz(rms)=0.1 Iz(dc) f=1KHz IR, LEAKAGE CURRENT(uA) Zz, DYNAMIC IMPEDANCE (Ω) 0.6 0.7 0.8 0.9 VF, FORWARD VOLTAGE (V) FIG.5 TYPICAL LEAKAGE CURRENT FIG.3 EFFECT OF ZENER CURRENT ON ZENER IMPEDANCE 1000 Zz, DYNAMIC IMPEDANCE (Ω) 0.5 10 1 125℃ 0.1 5 mA 20mA 0.01 10 25℃ 0.001 3 1 1 10 100 4 5 6 7 8 9 10 11 12 13 Vz, NOMINAL ZENER VOLTAGE(V) Iz, ZENER CURRENT(mA) Version:G11 14 15 RATINGS AND CHARACTERISTIC CURVES (1SMA4737 THRU 1SMA200Z) FIG. 7 TEMPERATURE COEFFICIENTS FIG.6 TYPICAL CAPACITANCE versus Vz 12 1000 θVz, TEMPERATURE COEFFICIENT (mV/℃) C, CAPACITANCE(pF) a-RANGE FOR UNITS TO 12 VOLTS 0V BIAS 1.0V BIAS 100 50% OF BREAKDOWN 10 1 10 Vz, FORWARD VOLTAGE (V) 10 8 6 4 2 RANGE Vz@ IZT 0 -2 -4 100 2 3 5 6 7 8 Vz, ZENER VOLTAGE(V) 9 10 11 12 FIG. 9 EFFECT OF ZENER CURRENT FIG.8 TEMPERATURE COEFFICIENTS 6 100 b-RANGE FOR UNITS 12 TO 100 VOLTS θVz, TEMPERATURE COEFFICIENT (mV/℃) θVz, TEMPERATURE COEFFICIENT (mV/℃) 4 RANGE Vz@ IZT 10 1 10 100 Vz, ZENER VOLTAGE(V) Vz@ IZT TA=25℃ 4 0.01mA 1 mA 2 20mA 0 -2 NOTE:BELOW 3 VOLTAGE ABOVE a VOLTS CHANGES IN ZENER CURRENT NOT AFFECT TEMPERATURE -4 3 3.5 4 4.5 5 5.5 6 6.5 Vz, ZENER VOLTAGE(V) 7 7.5 8 FIG.10 MAXIMUM SURGE POWER PPK, PEAK SURGE POWER WATTS 100 5% DUTY CYCLE 11V-91V NON-REPETITIVE RECTANGULAR WAVEFORM TA=25℃ PRIOR TO INITIAL PULSE 0.8V-10V NON-REPETITIVE 10 10% DUTY CYCLE 20% DUTY CYCLE 1 0.01 0.1 1 10 100 1000 PW, PULSE WIDTH (ms) Version:G11
