I have the following circuit that uses a NPN transistor as a switch:
I've built the circuit on a PCB, and while testing I noticed the following plateau in Vce (blue trace) when Vb transitions to zero (yellow trace):
Does anyone know what is causing this? It never showed up in any of my simulations with LTSpice.
I've played around with including a BAT54 Schottky diode between base and collector to prevent saturation, but the odd plateau remains.
