high current transistor

Its my first time here. The circuit may be understood as follows: The voltage from the solar panel enters the IC7812 first, the three diodes connected at the GND of the IC elevates the output voltage to about 14.26V which is the ideal voltage for charging 12V batteries. provide the coil details and the battery details. If not, how many cellphones can it charge at once? My phone needs atleast 800ma to charge. so in that case the BJT will hardly conduct….you can try increasing the 1 ohm to 2 ohms or use a higher rated load that would consume at least 1 amp from the IC. One interesting and very useful application circuit using a couple of TIP36 transistor can be made for charging high current batteries in the order of 150 AH, directly from solar panels. The main datasheet, specifications and features are as follows: Collector to Emitter Continuous Voltage:VCEO(sustained) = 300V minimum for (TIP150)VCEO(sustained) = 350V minimum for (TIP151)VCEO(sustained) = 400V minimum for (TIP152)Collector−Emitter Saturation Voltage: VCE(sat) = 2V maximum at I current of 5A. ok, it is correct as a working principle, but with current values ​​it can only deliver 1 or 2 amps, not 25 amps as you say. The output will be current controlled and safe. That’s not correct. To enhance the current gain of the circuit, you can add a TIP127 with the TIP36, as shown below. Collector Current (Ic) = 25 Amp continuous, peak 50 Amp for 5 ms only. And if i use L7805 with it, the current output will drop to 10mA.

Hi..It's great to see this sort of resource freely available and supported..I've been searching unsuccessfully to find a 10 amp (or similar)constant current battery charger circuit for 12v lead acid batteries using an LM317 with power transistors inside the feedback loop. Absolute Maximum Ratings: The device will not tolerate anything above the following parameter magnitudes: Collector-base Voltage (Vcbo) = 100 volts I know that, but these are the absolute maximum values.It cannot be practically reached. l •‰6.ö:ƒáÌ3„Ï,Ö .AÿDw› bSè„.n Å? Hi my name is john and I liked the project solar battery charger using the tip 36 transistor I liked the way the diagram showed the orientation of the components it showed the acual pinout of the reg as is I have been studying electronics for 20 years and I think diagrams should show the pinouts for example every time I see a transistor in a diagram I have to refer to my manual for the correct pinout when it can be shown on the acual diagram at glance the orientation of each and every part. Should I try to plug in the 150W solar panel and a 100Ah battery? Please sir, i have a 650VA UPS that is powered with a 12v, 7AH rechargeable battery. Even if the diagram is powered by 24v the transistor must dissipate approximately 200w, Yes I agree, so here too it is assumed to be the absolute maximum value. Let's proceed and learn the datasheet and the specifications of this outstanding high current transistor - the TIP36: Typical Applications: Audio Amplifier; Inverters; Motor Control; Solar Chargers. TIP36 is rated to dissipate 125 watts without heatsink if the ambient temperature is at 25 degrees Celsius. However at this point the TIP36 stays inactive, because of the absence of any voltage across its base/emitter 1 Ohm resistor.

Datasheet has clearly suggested that the device is designed to work with 25 amp continuous current, and I am sure they must have also applied some margin to it.
