1 I need 510 K 5 Watt resostor but unable to find in market.can any body suggest where to procure?

2 I want to replace double diode (S20LC20)20A200V.Can I use D92-02/BYV34 along with S20LC20?

3 How to check the voltage output of an IC.I.E. KA7535 is 16 pin IC,I want to measure volt at 15 no pin.I will put one prob on 15 no pin and another prob on which pin? which is ground pin?

Please do reply asap

 

1) Try Allied Electronics, google them. They will have, if not 510K, then 500K, which is close enough. Or 2 1Meg resistors in parallel will work. So will a 470K. Just be sure they are rated 5W or Greater.

2) not sure, no time to research that for you!

3) Check the data sheet for the KA7535, it will show you the gnd connection. Google it! But your method to check the voltage is correct.
