If you don’t know what I’m talking about, then look it up and study it.

Furthermore, the Vbe will be about 0. The only way you can make this design usable is to add resistors in series with the LEDs.

You need to keep in mind that, with a 5 volt supply, trabsistor putting out. However, since you seem to be having heat problems, I’ll assume that your transistor is not being properly driven.

Parts labeled as “pulls” or “pulled” have been previously installed and are made by the original manufacturer. The price may be the seller’s own price elsewhere or another seller’s price. Actually, from the data sheet, at 1 amp collector current, a mA base drive will only drop your Vce to 5 volts using the C, so I don’t recommend using it.

Fuji C Toshiba 2SC https: The only hold-up is that I have tried two different NPN transistors salvaged from old CRTs and both end up with Vce voltages around 35V causing them to heat up rather quickly since the current is around 1 amp. Yes but your meter is not fast enough to show you that Vce is not constant, it is a quickly varying voltage. So the resistor should be about 10 ohms. I have been working on a high-powered LED light bar.

But do take power dissipation into account. 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.

As Andy aka has pointed out, you are not measuring the Vce on of the transistor.

I will link the datasheets for the two in below. You can’t bring Vce down – you are operating it with pulse width modulation therefore the transistor is either fully-on of fully-off. Please educate yourself first before proceeding. This means that, for a load current of 1 amp, you’ll need about mA of base current, which should be well within the capabilities of a The design powers them almost directly from the mains, but tranisstor current using a and beefier NPN. Second, I probably should have indicated that I am used 9x 10W 12V LEDs which I did a few tests on before hand to obtain a general range of internal resistance.

Below is a simplified schematic. You must not treat a string of LEDs as having a resistance! Essentially I know the circuit works.

This is the price excluding shipping and handling fees a seller has provided at which the same item, or one that is nearly identical to it, trsnsistor being offered for sale or has been offered for sale in the recent past. Andy aka k 10 Skip to main content. You may also like.
