12V
Zener 12 V.129 circuits use this part. Listed as: Zener diode, 12V, DO-41; Zener diode 1/2W, 12V; Standard Diode; Zener diode, 12V 1W DO-41; Diode BZX55C12.
Zeners for 12 V
The parts list gives only the voltage, so any zener of that voltage fits. A 500 mW part in DO-35 suits clipping and most pedal uses; the 1 W and 1.3 W parts are larger (DO-41) and only needed where the zener carries real current, such as clamping a supply rail. Check the spacing on the board before ordering the bigger body.
