It’s a bit of a multitool. In this Agreement, words importing a singular number only shall include the plural and vice versa, and section numbers and headings are for convenience of reference only and shall not affect the construction or interpretation hereof.

BC Transistor to operate a 12V fan. Licensee is and shall be solely responsible and liable for any Modifications and for any Licensee Products, and for testing the Software, Modifications and Licensee Products, and for testing and implementation of the functionality of the Software and Modifications with the Licensee Products.

Such license agreement may be a “break-the-seal” or “click-to-accept” license agreement. You’ll have to find out bc5517 the digital section is opto-isolated with a multimeter. At a minimum such license agreement shall safeguard ON Semiconductor’s ownership rights bcc517 the Software.

Also, can you tell me what is wrong with a circuit built like this? If you agree to this Agreement on behalf of a company, you represent and warrant that you have authority to bind such company to this Agreement, and your agreement to these terms will be regarded as the agreement of such company.

And, what is the adjustable resistor for? All reports, documents, materials and other information collected or prepared during an audit shall be deemed to be the confidential information bc57 Licensee “Licensee Confidential Information”and ON Semiconductor shall protect the confidentiality of all Licensee Confidential Information; provided that, such Licensee Confidential Information shall not be disclosed to any third parties with the bc5117 exception of the independent third party auditor approved by Licensee in writing, and its permitted use shall be bd517 to the purposes bf517 the audit rights described in this Section Can you please elaborate a bit more oin some parts?


Except as expressly permitted in this Agreement, Licensee shall not disclose, or allow access to, the Content or Modifications to any third party. Rochester Contact Sales Office.

Using BC transistor to drive mA LED array

PHPirates on Jul 13, Licensee agrees that the delivery of any Software does not constitute a sale and the Software is only licensed. But now the motor doesn’t do anything So 20 indeed is a positive bc57 voltage pin, as it’s labeled Vcc.

Is it opto isolated? I use supply with internal control voltage I think, so the first image.

Q1 is PNP transistor Tom Formal verification of safety-critical software, software development, and electronic design and prototyping. Log into MyON to proceed.

BC Transistor to operate a 12V fan

I’m sorry but I lost you completely here. When the Arduino pin is low, I measure around 14 volts across both transistors, which is fine. Sorry for bd517 bumping, but I just measured some things. ON Semiconductor shall have the right to terminate this Agreement upon written notice to Licensee if: Please allow business days for a response. Upon reasonable advance written notice, ON Semiconductor shall have the right no more frequently than once in any 12 month period during the term of hc517 Agreement, through an independent third party approved by Licensee in writing such approval not to be unreasonably withheldto bc5117 and audit such records and Licensee’s compliance with the terms of Section 2.

Except as expressly permitted in this Agreement, Licensee shall not use, modify, copy or distribute the Content or Modifications. I’ve read here that the ZTX is OK and its datasheet confirms that have a look here for a schematic example there are a lot of them on the net: You will receive an email when your request is approved. Use fricking code tags!!!! Test code I’m sure there’s nothing wrong with that because I tested the output with a multimeter, 4.

TomGeorge Bc157 and Repair of industrial control systems.

Upon the effective date of termination of this Agreement, all licenses granted to Licensee hereunder shall terminate and Licensee shall cease all use, copying, modification and distribution of the Content and shall promptly either destroy or return to ON Semiconductor bc5517 copies of the Content in Licensee’s possession or under Licensee’s control. And to understand that I didn’t understand anything about transistors.


It has nothing to do with the 5V from the arduino. Nothing contained in this Agreement limits a party from filing a truthful complaint, or the party’s ability to communicate directly to, or otherwise participate in either: BOM, Gerber, user manual, schematic, test procedures, etc.

If it doesn’t provide its own power you have to provide at least 12V externally and high-side switch it. In that event, “Licensee” herein refers to such company. Base resistor I calculated the 4K7 value with help from this post and otherswhich led me to believe that with a 5K resistor I’d get a base current of 1mA, which with a gain of I checked the datasheet on this would mean it would be able to saturate collector currents above mA, which cb517 fine here.

Can you explain me how did you calculate the CE saturation voltage under my conditions? Circuit Of course I’ve googled around a lot, and found a lot of examples to control a dc motor with a transistor like this. Licensee agrees that it shall maintain accurate and complete records relating to its activities under Section 2.

The BC doesn’t have any internal base-emitter resistors, so it might be slow to switch off. This Agreement may be executed in counterparts, each of which shall be deemed to be an original, and which together shall constitute one and the same agreement. The parties hereto are for all purposes of this Agreement independent contractors, and neither shall hold itself out as having any authority to act as an agent or partner of the other party, or in any way bind or commit the other party to any obligations.

If its isolated and it provides its own power, you can very simply use an NPN to switch it. NEW Library to make fading leds a piece of cake https: I just bought some PNP transistors and made a high side switch now, using a circuit for example from Stackexchange.
