The ±5% tolerance on the nominal voltage means the actual breakdown falls between 5.32 V and 5.88 V — tight enough for a reference rail or input clamp where the downstream regulator can absorb the spread. ## Impedance and leakage — what they mean for the bias point Maximum Zener impedance (Zzt) is 5 Ohms at the test current — the dynamic resistance at the knee. A 5.6 V rail loaded with a few mA sees the output shift by roughly 5 mV per mA of load change, which is acceptable for a simple shunt regulator but not for a precision ADC reference. Reverse leakage is 10 µA maximum at 2 V reverse bias, well below the self-heating threshold in a high-impedance divider. The DO-214AC package with a copper pad under the cathode tab sets the thermal resistance — the 2 W rating assumes adequate board copper for heat spreading. In a dense layout, derate based on the actual trace area and adjacent component heating.","metaTitle":"Microchip SMAJ4734AE3/TR13 Zener Diode, 5.6 V, 2 W, DO-214AC","metaDescription":"Microchip SMAJ4734AE3/TR13 Zener diode, 5.6 V nominal, 2 W, DO-214AC SMA, ±5% tolerance, -55 to 150°C.
