For a 5 V rail shunt clamp or a low-voltage reference, that spread sets the guard band the downstream circuit must tolerate. ## Power handling and thermal budget Rated for 2 W maximum power dissipation in the DO-214AC (SMA) package. The junction-to-ambient thermal path is dominated by the copper pad area under the cathode tab — the datasheet derating curve should be referenced when the diode operates above 25 °C ambient. With a maximum Zener impedance of 5 Ohms at the test current, the voltage shift under a 100 mA load step is about 0.5 V — enough to matter in a precision reference but acceptable for general-purpose clamping or transient suppression. ## Temperature range and reverse leakage Reverse leakage is 10 µA maximum at 2 V reverse bias — negligible for most bias networks, but at 150°C the leakage multiplies per the Zener's temperature coefficient and should be budgeted in high-impedance circuits.","metaTitle":"Microchip SMAJ4734E3/TR13 Zener Diode, 5.6 V, 2 W, DO-214AC","metaDescription":"Active Microchip SMAJ4734E3/TR13 Zener diode, 5.6 V nominal, 2 W max, ±10% tolerance, DO-214AC SMA package, -55°C to 150°C.
