Minimum Limits

Author: Leonard Krugman

The minimum limits of the transistor are generally not critical in practical cases. The minimum collector voltage is set by the non-linear portion of the characteristic curve, which is not reached until the collector voltage is reduced to a few tenths of a volt. The minimum collector current must be greater than the saturation current Ico, which is considerably less than 100 microamperes in most junction types. The error introduced by assuming the minimum limits to be Ec = 0 and Ic - 0 is generally negligible.
