±2% are indicated by a “B” instead of “C.”
The zener impedance is derived from the 1 kHz cycle ac voltage, which results when an ac

APPLICATION NOTE
Since the actual voltage available from a given zener diode
temperature and may be found as follows:
is temperature dependent, it is necessary to determine junc-
tiontemperatureunderanysetofoperatingconditionsinorder
to calculate its value. The following procedure is recom-
mended:
∆T = θ P .

vary with time and may also be affected significantly by the
zenerresistance. Forbestregulation, keepcurrentexcursions
as low as possible.
Surge limitations are given in Figure 5. 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 5 be exceeded.
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-
sured value of T , the junction temperature may be deter-
L
mined by:
T = T + ∆T .
