Maximum impedance (Zzt) is 2.5 Ohms, which governs the voltage shift under load current. Reverse leakage is specified at 5 µA maximum when the applied voltage is 5.2 V — well below the Zener knee, so the diode draws negligible current in the off state until it reaches breakdown. Forward voltage drop is 1.2 V max at 200 mA forward current. ## Package, mounting, and compliance The supplier device package is designated DO-214AC (SMAJ).","metaTitle":"Microchip SMAJ5921BE3/TR13 Zener Diode, 6.8 V, 1.56 W","metaDescription":"Microchip SMAJ5921BE3/TR13 Zener diode, 6.8 V nominal, ±5% tolerance, 1.56 W max dissipation.
