The ±2% tolerance on Vz means the actual Zener voltage at the test current will fall between 4.998 V and 5.202 V — tight enough for a 5 V rail clamp or reference in a low-power bias supply. ## Thermal and leakage profile Rated for continuous operation from -65 °C to +150 °C, this diode suits environments from cold-start outdoor gear to hot-side industrial enclosures. Reverse leakage is specified at 10 µA maximum when 1 V is applied across the junction — a low enough draw to avoid loading a high-impedance bias node in standby circuits. Maximum Zener impedance (Zzt) is 7 Ohms, which governs the voltage regulation under varying current; a stiffer supply demands a lower-impedance Zener, but 7 Ohms is typical for a 5.1 V, 1 W part. ## DO-41 axial package for through-hole assembly Housed in a DO-204AL (DO-41) axial-lead package, the 1N4733CP/TR8 is supplied on Tape & Reel for automated insertion into through-hole boards. The axial body and 0.025-inch diameter leads are compatible with standard 0.100-inch pitch PCB layouts and wave-solder profiles.","metaTitle":"Microchip 1N4733CP/TR8 Zener Diode, 5.1 V, 1 W, DO-41","metaDescription":"Active-production 5.1 V Zener diode, 1 W, ±2% tolerance, DO-204AL (DO-41) axial package. -65 to +150 °C range.
