So the stability of the tube is inseparable from the manufacturing process, and poor workmanship may result in the inconsistency of the parameters of these small tubes. Their various switching actions are almost the same. Of course, when they burn out, there must be a small tube that can't bear it first.

When necessary, an accelerating capacitor can be connected in parallel with R4. R1 provides the base current limit for Q3 and Q4, and R4 provides the gate current limit for the MOS tube, that is, the Ice limit of Q3 and Q4. .

The circuit that makes the transistor work only in the 1 and 3 states is called a switching circuit. Generally, the transistor is turned off, and the collector does not absorb current to indicate the off; when the transistor is saturated, the voltage difference between the emitter and the collector is close to 0V. .
