Electrical Specifications @ +25 ºC (Unless Otherwise Specified)
NOTE1: No Suffix type numbers are +20% with guaranteed limits for only VZ, lR, and VF. Units with “A” suffix are +10% with guaranteed limits for
VZ, lR, and VF. Units with guaranteed limits for all six parameters are indicated by a “B” suffix for +5.0% units, “C” suffix for +2.0% and
“D” suffix for +1.0%.
NOTE 2: Delta VZ is the maximum difference between VZ@ IZT and VZ@ IZL measured with the device junction in thermal equilibrium.
