The 1 Ohm maximum impedance at the Zener test current means the regulation slope is tight — the output voltage shifts less than 1V per amp of shunt current, which keeps a 6V rail within tolerance under varying load. With an operating junction temperature range of -65°C to 150°C, this part handles the thermal extremes of military and industrial environments. ## Leakage and forward characteristics Reverse leakage is specified at 1 µA maximum at 3V reverse bias — half the nominal Zener voltage — so the diode does not load the protected rail during normal operation. The forward voltage is 1.2V maximum at 1A, which means the device can survive brief forward-current events such as inductive kickback without immediate failure, though it is not designed for sustained forward conduction. The ±5% tolerance on Vz is the standard grade for general-purpose shunt regulation and overvoltage clamping. For a 6V nominal part, the actual Zener voltage falls between 5.7V and 6.3V across the full operating current range. Microchip lists this part as Active with RoHS compliance confirmed. The base product number is SMBJ5340, and the /TR13 suffix indicates Tape & Reel packaging for automated pick-and-place assembly.","metaTitle":"Microchip SMBJ5340BE3/TR13 Zener Diode, 6V, 5W, DO-214AA","metaDescription":"Active Microchip Zener diode, 6V nominal, 5W power dissipation, ±5% tolerance, DO-214AA SMB package.
