En npn triple diffused planar silicon transistor 2sd color tv horizontal deflection output applications applications color tv horizontal diflection output.

Power amplifier with datashet control and tone control overview the an is an integrated circuit designed for 4. Here is pic of coil on left and latest circuit drawing.

D datasheet npn power transistor 3a, 60v mospec. Ua smd datasheet, cross reference, circuit and application notes in pdf format. The main function of this circuit setup, is to pulse charge a battery using the current flowing through an oscillator coil.

Actual voltage through oscillator is Safe operating area and collector characteristics of the protected obsolete products obsolete products power transistor. Search 2sd online from elcodis, view and download d pdf datasheet, diodes, rectifiers specifications. When the transistor is off, the built in diode between the collector and emitter immediately becomes reverse biased from the DC supply voltage appearing across it and the kickback pulse flyback coming from the coil will also appear in reverse direction.


Have been finding using higher and higher voltage inputs is increasing efficiency of power flowing through oscillator datasgeet and into the 12 volt tractor battery. The objective is to charge the battery with the highest throughput efficiency. D datasheet, d pdf, d data sheet, d manual, 2sd178 pdf, d, datenblatt, electronics d, alldatasheet, free, datasheet, datasheets, data sheet.

Da nec discrete semiconductors jotrin electronics. Price for this transistor is here and notice it has no integrated diode across the collector-emitter and while you could use a fast diode there, maybe it would not be needed at all. The results at That is 4 watts flowing through the circuit into the charge battery and 4.

The tl device provides for pushpull or singleended output operation, which can be selected. D datasheet color display horizontal deflection output. Monolithic linear ic la tv and crt display vertical. I am now using my watt boost converter as the input power supply, so i can raise the voltage even further to test any efficiency increases.

When using an input voltage of D nte equvilent nte npn horizontal deflection transistor nte silicon npn transistor color tv horizontal deflection output.

I think this boost converter can only reach around 90 volts though. I am using the 2SD, because it’s what i had on hand salvaged at the moment, since i fried my audio transistor i was using. In case diagnosis circuit that detect unusual case is operated, npn transistor q1 is turned on.


Hi all, I have been testing this charger variant and testing different voltages. Also, you use a relatively good HV switching transistor, the only ‘issue’ I can mention would be its rather low hFE, DC current gain of 8 to 10 at around 1 to 4A collector current range, from data sheet: Efficiency is now 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.

I 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.

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. Slvsh january revised march tl pulsewidth.
