The ±2% tolerance on the Zener voltage means the regulation point stays between 4.998 V and 5.202 V at the test current — tight enough to bias a logic supply rail or clamp a 5 V bus without overshooting the absolute-maximum ratings of downstream 5 V logic. Maximum impedance (Zzt) is 7 Ohms at the Zener test current — the dynamic resistance determines how much the output voltage shifts with load current; a 7 Ohm Zzt at 5.1 V means a 10 mA change in bias current shifts the regulation point by roughly 70 mV. Reverse leakage is specified at 10 µA maximum at 1 V reverse — well below the Zener knee, confirming the diode blocks cleanly below the breakdown region with minimal standby current. Forward voltage is 1.2 V maximum at 200 mA forward current — if the diode is used in a bidirectional clamp or as a general-purpose rectifier in a low-current path, the forward drop adds to the conduction loss. Supplied in Tape & Reel (TR) packaging for automated pick-and-place assembly, though the DO-41 axial-leaded body is through-hole — the reel format suits high-volume insertion equipment with radial or tape-fed lead formers.","metaTitle":"Microchip 1N4733CP/TR12 Zener Diode, 5.1 V, 1 W, DO-41","metaDescription":"Active 5.1 V Zener diode in DO-204AL (DO-41) axial package. 1 W power dissipation, ±2% tolerance, -65°C to 150°C range.
