Reverse leakage is 10 µA maximum at 5 V reverse bias, so in a high-impedance divider the leakage current does not shift the bias point significantly. Microchip Technology lists this part as Active, meaning the die and assembly lines are still running. The Tape & Reel packaging (TR suffix) is the standard reel option for automated insertion — the same die is also available in bulk or ammo-pack variants under the base number 1N4737.","metaTitle":"1N4737P/TR8 Zener Diode, 7.5 V, 1 W, DO-41, Active","metaDescription":"Microchip Technology 1N4737P/TR8 Zener diode, 7.5 V nominal, 1 W power, ±10% tolerance, DO-41 axial package.
