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 maintaining the lead temperature (TL) at 30 C 1 C, from the diode body. 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. o o - 587 - Version: B07 RATINGS AND CHARACTERISTIC CURVES (1SMA4741 THRU 1SMA200Z) FIG.1- POWER TEMPERATURE DERATING CURVE PD, MAXIMUM POWER DISSIPATION (WATTS) FIG.2- TYPICAL FORWARD CHARACTERISTICS 1000 500 IF, FORWARD CURRENT (mA) 1.25 MINIMUM MAXIMUM 1.0 200 100 50 20 10 5 2 o 0.75 0.50 70 C 150 C 25 C 0C o o o 0.25 0 0 20 40 60 80 100 120 140 o 1 160 180 200 0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.1 AMBIENT TEMPERATURE( C) VF, FORWARD VOLTAGE (VOLTS) FIG.3- EFFECT OF ZENER CURRENT ON ZENER IMPEDANCE 1000 ZZ, DYNAMIC IMPEDANCE (OHMS) FIG.5- TYPICAL LEAKAGE CURRENT o 500 200 100 50 20 10 5 2 1 0.1 0.2 0.5 1 2 5 TJ = 25 C IZ(rms)= 0.1 IZ(dc) f = 1KHz 47V 10000 7000 5000 2000 1000 700 500 200 100 70 50 IR, LEAKAGE CURRENT ( A) TYPICAL LEAKAGE CURRENT AT 80% OF NOMINAL BREAKDOWN VOLTAGE 27V 0.8V 20 10 7 5 2 1 0.7 0.5 0.2 0.1 0.07 0.05 0.02 0.01 0.007 0.005 0.002 0.001 3 4 5 6 7 8 9 10 11 12 13 14 15 10 20 50 100 IZ, ZENER CURRENT (mA) FIG.4- EFFECT OF ZENER VOLTAGE ON ZENER IMPEDANCE ZZ, DYNAMIC IMPEDANCE (OHMS) 1000 700 500 200 100 70 50 20 10 7 5 2 1 1 2 3 5 7 IZ = 1.0mA 5.0mA 20mA TJ = 25 C IZ(rms)= 0.1 IZ(dc) f = 1KHz o +125 C o +25 C o 10 20 30 50 70 100 IZ, ZENER CURRENT (mA) VZ, NOMINAL ZENER VOLTAGE (VOLTS) Version: B07 RATINGS AND CHARACTERISTIC CURVES (1SMA4741 THRU 1SMA200Z) FIG.6- TYPICAL CAPACITANCE versus Vz 400 300 200 C, CAPACITANCE (pF) FIG.7- TEMPERATURE COEFFICIENTS a-RANGE FOR UNITS TO 12 VOLTS OVZ, TEMPERAYURE COEFFICIENT (mV/oC) +12 +10 +8.0 +6.0 +4.0 +2.0 0 -2.0 -4.0 2 3 4 5 6 7 8 9 10 11 12 VZ, ZENER VOLTAGE (VOLTS) 100 0V BIAS 1.0V BIAS 10 8 4 1 RANGE VZ @ IZT 50% OF BREAKDOWN BIAS 10 VZ, FORWARD VOLTAGE (VOLTS) 100 FIG.8- TEMPERATURE COEFFICIENTS b-RANGE FOR UNITS 11 TO 100 VOLTS FIG.9- EFFECT OF ZENER CURRENT OVZ, TEMPERAYURE COEFFICIENT (mV/oC) OVZ, TEMPERAYURE COEFFICIENT (mV/oC) 100 70 50 30 20 10 7 5 3 2 1 10 20 30 50 70 100 VZ, ZENER VOLTAGE (VOLTS) +6.0 +4.0 VZ @ IZT TJ=25 oC +2.0 RANGE VZ @ IZT 20mA 0 0.01mA 1.0mA NOTE: BELOW 3 VOLTS AND ABOVE a VOLTS CHANGES IN ZENER CURRENT OO NOT AFFECT TEMPERATURE COEFFICIENTS -2.0 -4.0 3 4 5 6 7 8 VZ, ZENER VOLTAGE (VOLTS) FIG.10- MAXIMUM SURGE POWER Ppk, PEAK SURGE POWER IWATTSO 100 70 50 30 20 10 7 5 3 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) 0.8V -10V NON 11V -9 -RE PET ITIV E 1V N ON- REP 5% D UTY C ETIT YCLE IVE RECTANGULAR WAVEFORM o TJ = 25 C PRIOR TO INITIAL PULSE 10% DUTY CYCLE 20% DUTY CYCLE Version: B07 |
