What's the use of 5th diode in this schematic..(which is in parallel with cap)?
This is a circuit to drive led from mains AC.
Sorry if this question is too simple or obvious.. I just want to know what that diode's doing there.
It is not zener.... it is clearly written top right "1n4007 x5", 4 used for bridge rectifier and last one is parallel with capacitor.Is there any chance that it is a zener diode for clamping the DC voltage at the output?
It is not zener..It IS a zener diode
I still disagree, it SHOULD be a zener, and having now heard the origin of this hand drawn circuit it's likely that it's been drawn out wrongly - or it was 'designed' (and I use the term VERY loosely) by someone with no knowledge of what they were doing.It is not zener.... it is clearly written top right "1n4007 x5", 4 used for bridge rectifier and last one is parallel with capacitor.
