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 3. ZENER IMPEDANCE (Z ) DERIVATION

andZ aremeasuredbydividingtheacvoltagedropacrossthedevicebytheaccurrent

applied. The specified limits are for I (ac) = 0.1 I (dc) with the ac frequency = 60 Hz.

NOTE 4. MAXIMUM ZENER CURRENT RATINGS (I

)

Values shown are based on the JEDEC rating of 400 mW. Where the actual zener voltage

(V ) is known at the operating point, the maximum zener current may be increased and is

limited by the derating curve.

NOTE 2. ZENER VOLTAGE (V ) 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.

Since the actual voltage available from a given zener diode

is temperature dependent, it is necessary to determine junc-

tiontemperatureunderanysetofoperatingconditionsinorder

to calculate its value. The following procedure is recom-

mended:

Lead Temperature, T , should be determined from:

T = θ

+ T .

2.4–60 V

isthelead-to-ambientthermalresistance(°C/W)andP is

the power dissipation. The value forθ willvaryanddepends

onthedevicemountingmethod.θ isgenerally30to40°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

thermocoupleplacedontheleadascloseaspossibletothetie

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 mea-

mined by:

∆T is the increase in junction temperature above the lead

temperature and may be found from Figure 2 for dc power:

∆T = θ P .

voltage, V , can then be found from:

VZ J

, 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

zenerresistance. Forbestregulation, keepcurrentexcursions

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 ex-

tremely high in small spots, resulting in device degradation

should the limits of Figure 7 be exceeded.
