6N (Siemens) – Low Input Current, High Gain Optocoupler | eet
C free-air temperature at a rate of 2. Using a resistor between pin 5 and 7 will decrease gain and delay time. Exposure to absolute maximum ratings for extended periods of the time can adversely affect reliability.
If the gate is closed, we get a logic-0, if it’s open the resistor will pull the level to logic-1 Best Regards, Thorsten. I would like to understand how the output side of a 6N works.

If we’re taking the MBSIDv2 core schematic as a concrete reference with resistors, we have 5,6k at pin 7 going to ground, and pin 6 is connected to signal out and via a 1,2k resistor to ground.

I guess R2 can be found out using an oscilloscope, to see which size enables the shortest propagation delay like explained in the video at this point.
Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this document. Here is a 6N datasheet: I understand that the 5,6k resistor enables the output transistor to operate faster, but what about the 1,2k at pin 7?
There’s different MIDI out schematics on the net with the value varying a lot from R to 10k, even though the latter was on a 6N which might make a differenceso is it that the output current doesn’t really matter as long as it’s not too bigwhat matters is only whether the voltage at pin 6 is high or low? The MIDI specification gives a schematic only for PC optocoupler and mentions that 6N or others can be used with modifications, but doesn’t say what those modifications are.
Typical values are for information only and are not part of the testing requirements.

The circuit that I have is the one below sorry that the image is a bit darkand my question is what function do the resistors R1 and R2 serve, and how would one go about determining the best values.
Access to the base terminal allows adjustment to the gain datashewt.
This is a pull-up resistor. You need to be a member in order to leave a comment.
Sorry if my original mail wasn’t clear enough. Compliance with the safety ratings shall be ensured by means of protective circuits. Especially I’d be interested in a step by step walkthrough on how the transistors work when the first one in the series a phototransistor, I take it gets a signal from the LED.

Posted 26 Sep edited. I’ve tried R1 values for circuit below at R, 1k, 4. Please contact authorized Vishay personnel to obtain written terms and conditions regarding products designed for such applications. Refer to wave profile for soldering conditions for through hole devices DIP.
High common mode transient immunity and very high current ratio together with VAC insulation are achieved by coupling an LED with an integrated high gain photo detector in an eight pin dual-in-line package. Sign In Sign Up. Posted 27 Sep
