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 Suffix denotes + 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 of 25C + 3C. 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.
