DESIGN DATA
CASE:
Hermetically sealed glass
case. DO – 35 outline.
LEAD MATERIAL:
Copper clad steel.
LEAD FINISH:
Tin / Lead
THERMAL RESISTANCE: (R
OJEC):
250 ˚C/W maximum at L = .375 inch
THERMAL IMPEDANCE: (Z
OJX): 35
˚C/W maximum
POLARITY:

* JEDEC Registered Data.
NOTE 1
The JEDEC type numbers shown above have a Zener voltage tolerance of + 5% of
the nominal Zener voltage. Vz is measured with the device junction in thermal equilib-
rium at an ambient themperature of 25°C + 3°C. A “C” suffix denotes a + 2%
tolerance and a “D” suffix denotes a + 1% tolerance.
Zener impedance is derived by superimposing on l ZT A 60Hz rms a.c. current equal
to 10% of l ZT (25
µ
A a.c.)
