6N NTE Equivalent NTE OPTOCOUPLER TTL COMP - Wholesale Electronics
Thermal Pad is needed or not? South America Argentina Brazil. It limits its own voltage to from 1. You agree that the Information as provided here through an intermediary may not be error-free, accurate or up-to-date and that it is not advice. IR Started by transforman2 Today at 6: You must know the resistance 6136 the relay coil or your driving transistor might blow up.
Singapore Thailand Vietnam Other Countries. You have chosen to save the following item to a parts list:.
Please select an existing parts list. The product detailed below complies with the specifications published by RS Components. If you drive a transistor from the parallel port, you have 6b136 tie the grounds together.
Siemens - datasheet pdf
Do not connect to the base of the transistor pin 7. Hi, I am a complete newbie in electronics so kindly be gentle.
Its gain drops above about mA. Click here to register now. Taiwan Chinese Other Countries. The max allowed output voltage of the 6N is only 20V so it cannot be used to drive a 24V relay. See a list of all our websites. A reverse-connected diode must be connected across the relay coil to arrest the hundreds of volts it tries to generate when it turns off.

Roff Well-Known Member Dec 1, My biggest confusion right now is where to get the output. You do not understand how a 6b136 works. Articles Top Articles Search resources. Sending feedback, please wait Between Pin 8 and Pin 6? Or, what is the maximum voltage I can use to drive the emitter with appropriate resistors?
An ordinary transistor can easily drive the relay. Its minimum logic high current is only 2. The load connects to its collector pin 6 and to the external positive supply voltage of 20V or less. Kuwait Lebanon 6n16 Qatar. You need to know how much current. The output high voltage of a parallel port is not 5. RoHS Certificate of Compliance.
A 2N might be best because it still has lots of gain up to about mA. It is a transistor with its emitter grounded.
