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. MOUNTING POSITION: ANY. * 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 equilibrium 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.)
