Notes: 1. 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(TL) 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 IZT or IZK 5. Surge Current (IR) Non-Repetitive. The rating listd in the electrical chatacteristics 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 11 Version:F12 RATINGS AND CHARACTERISTIC CURVES (1N4740A THRU 1M200Z) FIG. 2 TYPICAL FORWARD CHARACTERISTICS FIG. 1 POWER TEMPERATURE DERATING CURVE 1000 1.25 1 IF, FORWARD CURRENT (mA) PD, MAXIMUM POWER DISSIPATION (WATTS) MINIMUM MAXIMUM 0.75 0.5 0.25 100 0 25℃ 25 50 75 100 125 1 150 0.4 AMBIENT TEMPERATURE(℃) 0.5 0.6 0.7 0.8 1 1.1 FIG.5 TYPICAL LEAKAGE CURRENT 10000 TA=25℃ Iz(rms)=0.1 Iz(dc) f=1KHz TYPICAL LEAKAGE CURRENT AT 80% OF NOMINAL BREAKDOWN VOLTAGE 47V 100 0.9 VF, FORWARD VOLTAGE (V) FIG.3 EFFECT OF ZENER CURRENT ON ZENER IMPEDANCE 1000 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) 150℃ 10 0℃ 0 Zz, DYNAMIC IMPEDANCE (Ω) 70℃ 10 1 0.1 125℃ 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:F12 14 15 RATINGS AND CHARACTERISTIC CURVES (1N4740A THRU 1M200Z) FIG. 7 TEMPERATURE COEFFICIENTS FIG.6 TYPICAL CAPACITANCE versus Vz 12 1000 a-RANGE FOR UNITS TO 12 VOLTS θVz, TEMPERATURE COEFFICIENT (mV/℃) C, CAPACITANCE(pF) 10 0V BIAS 100 1.0V BIAS 50% OF BREAKDOWN 10 1 10 100 8 6 4 2 RANGE Vz@ IZT 0 -2 -4 2 3 4 Vz, FORWARD VOLTAGE (V) 6 7 8 9 10 11 12 Vz, ZENER VOLTAGE(V) FIG. 9 EFFECT OF ZENER CURRENT FIG.8 TEMPERATURE COEFFICIENTS 6 100 Vz@ IZT TA=25℃ 10 θVz, TEMPERATURE COEFFICIENT (mV/℃) b-RANGE FOR UNITS 12 TO 100 VOLTS RANGE Vz@ IZT 1 10 100 4 0.01mA 1 mA 2 20mA 0 -2 NOTE:BELOW 3 VOLTAGE ABOVE a VOLTS CHANGES IN ZENER CURRENT NOT AFFECT TEMPERATURE COEFFICIENTS -4 3 Vz, ZENER VOLTAGE(V) 3.5 4 4.5 5 5.5 6 6.5 7 7.5 8 0.9 1 Vz, ZENER VOLTAGE(V) FIG. 10 TYPICAL THERMAL RESISTANCE versus LEAD LENGTH 175 ΘJL, JUNCTION TO LEAD THERMAL RESISTANCE(℃/W) θVz, TEMPERATURE COEFFICIENT (mV/℃) 5 150 125 100 75 50 25 0 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 L, LEAD LENGTH TO HEAT SINK(INCHES) Version:F12 RATINGS AND CHARACTERISTIC CURVES (1N4740A THRU 1M200Z) FIG.11 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 0 1 10 100 1000 PW, PULSE WIDTH (ms) Version:F12 Ordering information Part No. 1N46xxA 1MxxxZ (Note) Package Packing INNER TAPE Packing code Packing code (Green) DO-41 3K / AMMO box 52mm A0 A0G DO-41 3K / AMMO box 26mm A1 A1G DO-41 5K / 13" Reel 52mm R0 R0G DO-41 5K / 13" Reel 52mm R1 R1G DO-41 1K / Bulk packing B0 B0G Note: "xx" is Device Code from 1N47"40"A thru "94"A, 1M"110"Z thru "200"Z AXIAL LEAD TAPING SPECIFICATIONS Outline DO-41 DO-41 A ±0.5 5 5 B ±1.5 26 52.4 Z MAX 1.2 1.2 T ±0.4 6 6 E ∣L1-L2∣ MAX MAX 0.8 1 0.8 1 D 330 330 Suggested Mounting Hole Rule Symbol A B C D Unit(mm) 5.1 0.8 3.0 1.2 D1 ±0.3 85.7 85.7 D0 ±0.4 16.6 16.6 Unit (mm) W ±1.0 76 76 Dimensions DIM.
