I was looking at making a fast pulse generator.its a very simple circuit using an avalanche transistor.It works like a flame detector where the diode conducts because of the UV light from the flame ,the HV on its anode collapses and it switches off,and it oscillates.
The circuit is very simple a 40 volt transistor supplied with 90 volts on its collector through a 1Meg resistor ,so it breaks into oscillation.
The question is "what exactly is a switching transistor? If you look a some data sheets like 2N4401 ,Philips say it is a switching transistor ,other manufacturers say it is a General Purpose transistor ?
