What Is IC Saturation?

What is VCE saturation?

saturation voltage, collector-emitter (VCE(sat)) The voltage between the collector and emitter terminals under conditions of base current or base-emitter voltage beyond which the collector current remains essentially constant as the base current or voltage is increased.

(Ref.

IEC 747‑7.).

How do you know if a BJT is in saturation?

Monitor the collector-emitter voltage of your circuit with a DMM. If the reading is below 0.3V, the transistor is at saturation. Transistors are having saturation voltage range from 0.7V and below but for a circuit designed for hard saturation, the VCE will be lower.

How do you calculate IC saturation?

Therefore Ic= a*Ie and Ic= B*Ib. Therefore Ic(saturation)<=aIe and Ic(saturation)<=BIb. And the corresponding saturation voltages are, Vbe(sat)= 0.8 volts, Vce(sat)= 0.2 volts, Vcb(sat)= -0.6 volts.

What is meant by saturation region?

Saturation region This is the region in which transistor tends to behave as a closed switch. The transistor has the effect of its collector and Emitter being shorted. The collector and Emitter currents are maximum in this mode of operation.
