With a ±10% tolerance and a maximum Zener impedance of 4 Ohms at the nominal voltage, this diode provides a stable reference or shunt regulator for low-power rails where the load current stays within the 1 W ceiling. ## Leakage and forward characteristics Reverse leakage is specified at 10 µA maximum when biased at 5 V — this is the standby current the downstream circuit sees before the diode enters breakdown. Forward voltage (Vf) is 1.2 V maximum at 200 mA forward current, typical for a silicon Zener in this power class; the forward drop matters if the diode is also used as a low-current rectifier or clamping element. Supplied in Tape & Reel (TR) packaging for automated assembly; the through-hole DO-41 body requires no special handling beyond standard axial component insertion.","metaTitle":"Microchip 1N4737PE3/TR12 Zener Diode, 7.5 V, 1 W","metaDescription":"Microchip 1N4737PE3/TR12 7.5 V Zener diode, 1 W, ±10% tolerance, DO-41 axial package.
