The formula to calculate the Collector to Emitter Leakage Current is:
\[ ICEO = (\beta + 1) \cdot Icbo \]
Collector to Emitter Leakage Current is a small collector current that flows if the base is open-circuited and the collector is reverse biased with respect to the emitter. Base Transport Factor is the factor of base current required to transfer emitter current to the collector of the BJT transistor. Collector Base Leakage Current is a small collector current which flows if the emitter is open-circuited and the collector-base junction is reversed biased.
Let's assume the following values:
Using the formula:
\[ ICEO = (2.5 + 1) \cdot 0.00034 = 0.00119 \text{ A} \]
