TIP32C transistor characteristics
The figure shows the DC current gain characteristics of the TIP32C transistor, the graph is plotted with dc current gain vs collector current.
At a fixed collector to emitter voltage, the current gain value starts from a fixed point and becomes constant with respect to collector current.
In the end, the DC current gain decreases.
The figure shows the saturation voltage characteristics of the TIP32C transistor, the graph is plotted with the base to emitter saturated voltage/emitter to collector saturated voltage with collector current.
At the fixed base current and collector current, the VCE(sat) voltage increases from the lowest value to a higher value and the VBE (sat) voltage will start from a higher value towards.
