3V3
Zener 3.3 V.15 circuits use this part. Listed as: Zener diode, 3.3V 1/2W; Zener diode 1/2W, 3.3V; Zener diode, 3.3V, DO-35; Zener diode 3.3V, 1/2W.
Zeners for 3.3 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.
