Does such a diode exist? The whole point of a diode is that it's unidirectional. Unless you mean a Zener, but I don't think it's a Zener. In any case I would assume the polarity is going to be opposite the relays triggering voltage, otherwise when the relay is "switched on" the current will go through the diode itself and not the relay. You can use a multimeter to find which way the current flows into the relay to switch it. | |

| Nov 19 at 8:31 | comment | added | fikri najmi | if i know the relay used? will i be able to know what kind of diode to use? the relay used is marked as jzc-42f. | |
| Nov 19 at 8:28 | comment | added | winny | Check the datasheet for the relay to tell for sure, but most probably just a flyback diode as you say. Try to trace out the circuit around the relay or find a service manual for it. | |
| Nov 19 at 8:26 | comment | added | fikri najmi | it is placed between a 24v relay. it is on the speaker output section. | |
