Suffix letter A denotes +10%. No Suffix denotes + 20% tolerance, "C" suffix denotes + 2% and "D" suffix denotes + 1%. Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C. Zener impedance is derived by superimposing on 1 A 60Hz rms a.c. current ZT equal to 10% of 1 ZT FIGURE 1 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 POLARITY: Diode to be operated with the banded (cathode) end positive.
