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

NOTE 1 NOTE 2 NOTE 3

Zener voltage tolerance on "A" suffix is +5%. No Suffixdenotes + 10% tolerance, "C" suffix denotes + 2% tollerance and "D" suffix denotes + 1% tolerance. Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of25°C + 3°C. Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of 1ZT

POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING...
