Hello given the situation below, i see that Ve>Vb and Vc>Vb so i assume its in saturation.
Given the attached datasheet,how do i know that my PNP is sutrated from the currents in the bjt?
Thanks.

 

Given the attached datasheet

That curve isn't for saturation mode. Vce will be low when the transistor is saturated.

how do i know that my PNP is sutrated from the currents in the bjt?

If you go by currents, it's when further increases in base current don't result in corresponding increases in collector current.

Saturation mode is defined as when the collector base junction becomes forward biased.

 

If I was trying to get to the graph you showed in post #1, I would use this circuit. I1 is a current source and will force the base current you see. 100uA or 200uA or ....
Now measure the C-E voltage and the C current.

 

Hello ronsimpson, I dont like doing simulations with current sources because ia m thinking with PCB logic.
In the lab i have voltage sources.
Could you make a voltage source interpretaion of the circuit?

 

You need to go back and review your voltage source/current source equivalents. Any problem you can solve with a voltage source has an equivalent solution with current source. LTspice may actually do that for you in some cases to improve the simulation.

To get saturation you need to force a situation where Ie is approximately 10 times Ib. You are not there yet. Your ratio is 24.8 ma / 758µA = 31.67
To get closer, set V1 to 4.2 Volts and reduce R4.

 

Could you make a voltage source interpretaion of the circuit?

Base current is the same as R1 current. (remember to subtract 0.67V)

ADDED:

Transistors respond to current not voltage.

Transistor controls by B-E voltage.
Base current is secondary parameter,
because it is part of emitter current, which
can not reach collector due parasitical
recombination of charge carriers in base volume.

 

The saturation region is the vertical line at the left of the graph.

 

It is not good to force a voltage on the B-E junction of a transistor. The graph in the data sheet does not have a line for 0.70V on the B-E. It has lines for Base current. Transistors respond to current not voltage.
Use a voltage source and resistor to set the base current.
