APPLICATION NOTE — ZENER VOLTAGE

Since the actual voltage available from a given zener diode
is temperature dependent, it is necessary to determine junc­tion temperature under any set of operating conditions in order
to calculate its value. The following procedure is recom­mended:

Lead Temperature, TL, should be determined from:

TL = θLAPD + TA.

θLA is the lead-to-ambient thermal resistance (°C/W) and PD is

the power dissipation. The value for θLA will vary and depends
on the device mounting method. θLA is generally 30 to 40°C/W
for the various clips and tie points in common use and for
printed circuit board wiring.

The temperature of the lead can also be measured using a
thermocouple placed on the lead as close as possible to the tie
point. The thermal mass connected to the tie point is normally
large enough so that it will not significantly respond to heat
surges generated in the diode as a result of pulsed operation
once steady-state conditions are achieved. Using the mea­sured value of TL, the junction temperature may be deter­mined by:

TJ = TL + ∆TJL.

∆TJL is the increase in junction temperature above the lead
temperature and may be found from Figure 2 for dc power:

∆TJL = θJLPD.

For worst-case design, using expected limits of IZ, limits of
PD and the extremes of TJ(∆TJ) may be estimated. Changes in
voltage, VZ, can then be found from:

∆V = θVZTJ.

θVZ, the zener voltage temperature coefficient, is found from

Figures 4 and 5.

Under high power-pulse operation, the zener voltage will
vary with time and may also be affected significantly by the
zener resistance. For best regulation, keep current excursions
as low as possible.

Surge limitations are given in Figure 7. They are lower than
would be expected by considering only junction temperature,
as current crowding effects cause temperatures to be ex­tremely high in small spots, resulting in device degradation
should the limits of Figure 7 be exceeded.

NOTE 1. TOLERANCE AND VOLTAGE DESIGNATION
Tolerance Designation

The type numbers shown have tolerance designations as follows:
1N4370A series: ±5% units, C for ±2%, D for ±1%.
1N746A series: ±5% units, C for ±2%, D for ±1%.
1N957B series: ±5% units, C for ±2%, D for ±1%.

NOTE 2. ZENER VOLTAGE (VZ) MEASUREMENT

Nominal zener voltage is measured with the device junction in thermal equilibrium at the lead
temperature of 30°C ±1°C and 3/8″ lead length.

NOTE 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.

NOTE 4. MAXIMUM ZENER CURRENT RATINGS (IZM)

Values shown are based on the JEDEC rating of 400 mW. Where the actual zener voltage
(VZ) is known at the operating point, the maximum zener current may be increased and is
limited by the derating curve.

NOTE 1. TOLERANCE

The JEDEC type numbers shown indicate a tolerance of ±5%. For tighter tolerance devices
use suffixes “C” for ±2% and “D” for ±1%.

NOTE 2. TEMPERATURE COEFFICIENT (θVZ)

Test conditions for temperature coefficient are as follows:

a. IZT = 7.5 mA, T1 = 25°C,

a. T2 = 125°C (1N5221B through 1N5242B).

b. IZT = Rated IZT, T1 = 25°C,

a. T2 = 125°C (1N5243B through 1N5281B).

Device to be temperature stabilized with current applied prior to reading breakdown voltage
at the specified ambient temperature.

NOTE 3. ZENER VOLTAGE (VZ) MEASUREMENT

Nominal zener voltage is measured with the device junction in thermal equilibrium at the lead
temperature of 30°C ±1°C and 3/8″ lead length.

NOTE 4. 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.
