The SMA4733A with Zener Diodes is a type of SMA RoHS (Restriction of Hazardous Substances) compliant component manufactured by AnBon. It is a two-element, two-terminal, single-diode surface mount series of low-power Zener diodes, designed for use in voltage regulator applications. The SMA4733A is constructed using ultra-thin oxide and low-resistance layers, allowing for tighter tolerances, better break-down voltage stability, and reliable electrical performance. It offers a low reverse leakage current with a maximum of 30 µA, a voltage range of 3.3V to 39V, a maximum rated power of 500 mW, a Zener voltage of +/-2%, and a maximum reverse operating voltage of 40V. The SMA4733A meets the JEDEC SOD-123FL standard test requirements and is ideal for a variety of consumer electronics devices.
