I try with several resistor values but the transistor never off. This resistor insures that the base of the transistor does not go slightly negative which would cause a very small amount of collector current to flow. Would somebody help me indicating me what must be the configuration and the correct resistors values? Oct 2, 17, 5, 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: This Agreement, including the Exhibits attached hereto, constitutes the entire agreement and understanding between the parties hereto regarding the subject matter hereof and supersedes all other agreements, understandings, promises, representations or discussions, written or oral, between the parties regarding the subject matter hereof.

How to use transistor(2N3906) to turn on relay?

However, during the term of this Agreement ON Semiconductor may from time-to-time in its sole discretion provide such Support to Licensee, and provision of same shall not create nor impose any future obligation on ON Semiconductor to provide any such Support.

Providing the control voltage source is floating not tied to ground you could use a circuit like this: Resistor R2 is not essential to this circuit but is generally used for stability and to insure that the transistor switch is completely turned off. These circuits are low in cost and offer ease of design for the radio amateur.

Show us the circuit you are using. Nobody can guess what, “v2” means. Nov 30, 18, 9, For example, if we have a load that requires MA of current and a transistor with a minimum HFE ofwe can then calculate the minimum base current required to saturate the transistor as follows: I am trying to use one rekay transistor as a switch.

Do you already have an account? You will receive an email when your request is approved. Nothing in this Agreement shall be construed as creating a joint venture, agency, partnership, trust or other similar association of any kind between the parties hereto. However, in the NPN transistor, R1 must be shorted to the positive end of the supply to turn the switch on.

Any such audit shall not interfere with the ordinary business operations of Licensee and shall be conducted at the re,ay of ON Semiconductor. The value of this resistor is not critical but a value about 10 times R1 is normally chosen.

Aug 1, 7, 2, You almost certainly are not saturating the transistor, even if you haven’t damaged the GPIO.

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 all copies of the Content in Licensee’s possession or under Licensee’s control.

With the control signal at GND, current flows through the base pullup resistor and the series resistor to pull the base to 3. Transistor switches are often used to take the low-level output from logic circuits to turn on or turn off a particular device.
