Yamaha RX A-1030

[Smoothjazz]

Hello,
I am starting to troubleshoot a power supply board for this Yamaha RX A-1030
receiver.I have pulled out a diode RB215T.I looked it up and its called a
Shotky Barrier Diode. Can someone explain to me how this 3 legged diode
works and what would good readings be?

The RB215T is a Schottky Diode. The -60 behind the first part of the RB215T is the voltage rating on it. Basically you put your multi meter into diode mode. Then you put your black probe to the middle pin and the red probe to either pin 1 or pin 3. Coording to the spec sheet you should see the Forward Voltage drop on your meter. On the RB215T-60 it would be 0.58V. Now reverse the leads and do the same test over again. But now your meter should show "OL". That would mean the diode is good.

For a bad diode the DMM shows a short, a 0.0V drop. If either pin 1 and or pin 3 are shorted to GND, the diode is bad. There are tons of youtube vids on this.
