The 6.2 V nominal breakdown at 2 Ohms impedance means it clamps the rail at that voltage with minimal slope — useful as a shunt regulator or voltage reference in a low-power supply where the load current stays under the 320 mA thermal limit at 25°C ambient. The ±5% tolerance on Vz means the actual breakdown sits between 5.89 V and 6.51 V — tight enough for a 5 V rail clamp but not for a precision reference where a 1% or 2% part would be specified. ## Leakage and forward drop — the secondary specs that matter Reverse leakage is 10 µA max at 3 V reverse voltage — this is the quiescent draw when the Zener is below breakdown. In a battery-powered circuit the leakage at the operating point (3 V on a 6.2 V Zener) is negligible, but if the rail sits near breakdown the leakage rises exponentially. Forward voltage is 1.2 V max at 200 mA — this is the drop when the diode is forward-biased. It matters if the part is used as a bidirectional clamp or if the forward conduction path carries significant current during a transient. The Tape & Reel packaging (TR suffix) is the standard reel quantity for automated pick-and-place assembly.","metaTitle":"Microchip SMAJ4735AE3/TR13 Zener Diode, 6.2V, 2W, DO-214AC","metaDescription":"Microchip SMAJ4735AE3/TR13 Zener diode, 6.2V nominal, 2W power, ±5% tolerance, DO-214AC SMA package.
