I am not trying trabsistor be over critical of an excellent In data sheet it says MHz transition frequency. You are saturating the transistor. This means that the rising waveform in the first photo is 5 x slower-rising than is apparent when making visual comparisons.

Previous 1 2 The higher collector resistor you connect, the worse switching response you will get. Doctorslo 80 1 1 9.

Trransistor at kHz of input signal: You will usually use a drive resistor from a source of maybe 5 volts, and this resistor value can make an immense difference to the result.

If you apply a “perfect” low frequency square wave to your probe, such as is often available on a calibration pin on your oscilloscope’s front panel, does it appear as a perfect square wave, or does it have a rounded leading edge?

Home Questions Tags Users Unanswered. The problem I am having is when I apply input square wave signal above KHz.

The various options that a power transistor designer has are outlined. This makes a difference when you are trying to find out what effects are really happening and where they are occurring. C B E the test assumes a model that is simply two diodes.

The molded plastic por tion of this unit is compact, measuring 2. I am having a transistor S Dand it’s connected like on the schematic below. And also – you do not show the driving source at the transistor base, and it matters.

The switching timestransistor technologies. Adding a capacitor of from under pF to maybe 1 nF across in parallel with the drive resistor may make a significant difference.

Whether construction is hardwired on eg vero board or on a plug in breadboard, whether you are using “bits of wire” or MHz probes or?

Knowing how trsnsistor circuit was built and the model of your scope probe and its settings become relevant at this sort of capacitance level.

To decrease the parasitic capacitance effect, use as low a impedance as you are willing to spend current for. BJT’s turn off slowly, especially when coming out of saturation. Another way is a Schottky diode from base to collector.

Most good or half good probes have an adjustment screw on the side which allows you to connect them to a “known square” waveform source and adjust the screw until a square waveform is applied.

It is likely that the circuit itself is swamping all these effects, but they start to come potentially significant at this level.

While this may seem to be somewhat cheating by MAKING a waveform look square regardless it is a valid operation as long as the waveform is in fact square.
