General description highvoltage,highspeed switching npn transistors in a plastic envelope with integrated efficiency diode,primarily for use in switching power circuites of colour. That is 4 watts flowing through the circuit into the charge battery and 4. It is possible though that the older types will have a low value hFE so you would need to pre-bias the base.

I will look at what transistors i can get, that are similar to what you describe, any improvements in efficiency is what i need. A1, february mje npn epitaxial silicon transistor absolute maximum ratings tc25c unless otherwise noted electrical characteristics tc25c unless otherwise noted.

Current flowing through circuit is. Have been finding using higher and higher voltage inputs is increasing efficiency of power flowing through oscillator circuit and into the 12 volt tractor battery. Which limits the peak charging voltage and in far less cycles, will cause the battery to sulphate and dxtasheet.

Then, use the flyback recovery of the coil to try and increase efficiency further and also help to reduce sulphation of battery and increase capacity.

Npn general purpose transistor book, halfpage m3d It is possible the DC pre-bias role of the 23 kOhm resistor would become obsolote i. In case of being unused this function, use this ic as openconnection on pin In case the coil has conditions for ringing like an LC circuit, then the diode may have a chance to conduct, this is not the likely case in your circuit.
Another advantage would be the lower dissipation in such transistor due to the much lower saturation voltage. I find these results promising, i will continue to raise the voltage by 10 volt increments and tune and share the data with you folks. Browse by manufacturer get instant insight into any electronic component.

Ics for audio common use an technical information continued volume control continued alternative responses of volume control may be obtained by addition of a diode across the resistor r4. Your thoughts on these 22sd1878 are very welcome, not much interest at the other forum apparently.
Question is what benefits such a transistor would bring versus the presently used one?

Datqsheet wonder if the built in diode is causing any loss of charging efficiency, i can’t see how it would though, unless it somehow conducts when the transistor is not conducting. I also have a capacitor in parallel with each of the resistors shown in the circuit drawing, it helps to adjust frequency and lower input.
The main function of this circuit setup, is to pulse charge a battery using the current flowing through an oscillator coil.
