Use the other one. Transistpr just cannot hope for the best that things won’t drift. See details for additional description. What you may measure is the average Vce. This item doesn’t belong on this page. LEDs have a very sharp voltage-current ttansistor.

Post as a guest Name. Parts labeled as “pulls” or “pulled” have been previously installed and are made by the original manufacturer. OK, some comments on your new schematic: I’d recommend that you double-check the LED current. However, since you seem to be having heat problems, I’ll assume that your transistor is not being properly driven.

I will link the datasheets for the two in below. Also Volts is dangerous, 1 A through the transistor.

Rtansistor only way you can make this design usable is to add resistors in series with the LEDs. Maybe the LEDs themselves are better protected internally and this saves the day as you believe but I cannot check this as I don’t have a data sheet or part number I’m not going to follow ebay links btw – if it aint got a data sheet pdf I wouldn’t buy it!

trasistor I have been working on a high-powered LED light bar. Same for D0, not needed. Take a look at this: Please educate yourself first before proceeding. Your LED current is unlimited, no wonder they burn out. I transiwtor know what I’m doing – this is a learning experience.

The rule of thumb is that, when a transistor is in saturation, it has a gain of about 10 to The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Do this by replacing the transistor with a 1 ohm, 2 watt resistor, and check the voltage across it.

As Andy aka has pointed out, you are not measuring the Vce on of the transistor. Your problem is much more fundamental to your design.

But do take power dissipation into account. Ok, first of all thank you for your feedback.

Yes but your meter is not fast enough to show you that Vce is not constant, it is a quickly varying voltage. Fuji C Toshiba 2SC https: Ground at bottom right: Actually, from the data sheet, at 1 amp collector current, a mA base drive will only drop your Vce to 5 trandistor using the C, so I ttransistor recommend using it.

You think you control Vce by changing R2 but you’re not. For high power LED drivers like this you really must know what you’re doing.

Best Selling in Transistors See all. Andy aka k 10 The price may be the seller’s own price elsewhere or another seller’s price. I have measured the output of the timer at 2V RMS and set the resistor values for each transistor according to their Ib vs Vce graphs around 0.

So the resistor should be about 10 ohms. Bad, bad circuit it seems. Skip to main content. You must not treat a string of LEDs as having a resistance! The “off” amount transistoe percentage simply signifies the calculated difference between the seller-provided price for the item elsewhere and the seller’s price on eBay.

Below is a simplified schematic. Your problem is most likely that you are not able to provide enough base current to turn the transistor fully on. What you need to learn first cannot be explained here in a few lines. Foremost, the inductor and feedback diode seem like a very good idea. You must choose at what current you want to operate them, make an estimate of the voltage usually around 2.
