Transistor Boundary Depth Scans

Saturation Voltage Floor Three-Row Scan

The stated saturation voltage sets the low output floor and changes load demand.

The stated saturation voltage sets the low output floor and changes load demand. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Zero-volt saturation gives a three-ampere load

Saturation voltage 0 V leaves load current 3 A and sets output floor 0 V.

Four-volt saturation raises the output floor

Saturation voltage 4 V leaves load current 2 A and sets output floor 4 V.
