If I were to employ the schematic below will the transistors survive.
I ask this because I was able to operate 3 low voltage(I'm guessing 1.5v), run of the mill junk LED's in series at a voltage of 340V @ 113uA using a 3M resistor with no ill result.
Is the same true for other semiconductor devices?
I'm building an off line power supply and making a linear regulator to power the primary control ICs seems like a terribly inefficient use of power.
The schematic works in simulation using LTSpice, but will the oscillator work on the breadboard or am I setting myself up for dead transistors?
EDIT The original reason for this question was because my reasoning was that .25W of power has the same charge (number of electrons) no matter the voltage. I = dq/dt, so that is essentially .25 coulombs per second at .25W.
if I=.25 and V=1 then P = .25 (P=VI) and since Q = 1 Ampere second or 1 Ampere is 1 Coulomb per second, therefore 1V at .25W should be .25Cu/sec and even if the voltage is 340V @ .25W, it is sill only .25Cu/sec. Transistors require sufficient current to operate correctly and even MOSFETs that are voltage controlled devices wont fully turn on unless they get sufficient charge (I know from personal experience), so that is why I think they may work in simulation.
I'm still a student in AC Theory, so I'm jumping ahead a little, but I figured in reality I would see an expectable voltage drop, like I did over the LEDs. There was a 335V (5V remaining) drop over just 3 little crap LEDs running at 340V in the uA range.
In a search for a totally different topic I came across this post where in the answer the user states:
The problem is that you are expecting a model to have more functionality than it has. Most models are simply parameters in an equation. They are designed to approximate the actual device behavior within specific operating conditions. For example, a diode is modeled using the following equation:
\$\Large I_f = I_S(e^{\frac{Vf}{NV_t}} - 1)\$ Where Vf is the applied voltage and If is the forward current. Notice that there's nothing stopping me from putting 50V as the applied forward voltage, and I will definitely get an answer from the simulator. It will be completely nonsense, but the model is assuming that the behavior of the diode is always described by that equation.
Which combined with the answers below provides me with a complete understanding of why the 2N2222 worked in simulation but WILL NOT work in a "real world" application.
Thank you all for your assistance. I is well appreciated.
