DESIGN DATA
CASE: Hermetically sealed glass case, DO41. LEAD MATERIAL: Copper clad steel LEAD FINISH: Tin / Lead THERMAL RESISTANCE: (ROJEC): 80 °C/W maximum at L = .375 inch THERMAL IMPEDANCE: (ZOJX): 15
°C/W maximum
NOTE 1 NOTE 2 NOTE 3
No suffix = + 10% tolerance on nominal Zener voltage, suffix "A" signifies +5%, suffix "C" signifies + 2%, suffix "D" signifies + 1%. Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of 1ZT. Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25°C + 3°C.
POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any.
