Note 1: Standard tolerance is 5%. “C” suffix is 2% tolerance and “D” suffix is 1% tolerance.
Note 2: Voltage regulation V
Z(reg)
is the measured voltage change at thermal equilibrium between the current of 10% and 50% of maximum zener current (I
ZM
) when the lead temperature is
maintained at 25°C = +8°C, -2°C.
