THERMAL RESISTANCE: (ROJEC):
250 ˚C/W maximum at L = .375 inch
NOTE 1
No Suffix type numbers are +20% with guaranteed limits for only VZ, lR, and VF. Units
with “A” suffix are +10% with guaranteed limits for VZ, lR, and VF. Units with guaranteed limits for
all six parameters are indicated by a “B” suffix for +5.0% units, “C” suffix for +2.0% and “D” suffix
for +1.0%.
NOTE 2
Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C + 3°C.
NOTE 3
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of 1ZT.

FIGURE 1
DESIGN DATA
CASE: Hermetically sealed glass
case. DO – 35 outline.
LEAD FINISH: Tin / Lead
THERMAL IMPEDANCE: (ZOJX): 35
˚C/W maximum
Reverse leakage currents are measured at VR as shown on the table.
∆VZ is the maximum difference between VZ at lZT and VZ at lZL measured with
the device junction in thermal equilibrium at the ambient temperature of +25°C +3°C.
POLARITY: Diode to be operated with
the banded (cathode) end positive.
MOUNTING POSITION: Any.
