5.6 V Zener, 2 W, DO-214AC — parametric fit for voltage reference and clamping
The Microchip SMAJ4734CE3/TR13 is a 5.6 V Zener diode in the standard DO-214AC (SMA) surface-mount package, rated for 2 W continuous power dissipation. The ±2% tolerance on the nominal voltage means the actual Vz stays between 5.488 V and 5.712 V — tight enough for a reference rail or a low-voltage clamp where the margin matters. Maximum impedance (Zzt) is 5 Ohms at the test current, so the regulation slope across the operating current range is shallow — the output voltage shifts less than 50 mV per mA of load change. The 10 µA reverse leakage at 2 V confirms the knee is sharp; this diode starts conducting well below the nominal voltage.
