Working Principle

The SML4729-E3/61 is a high-performance zener diode that functions by controlling the flow of current between two points. It is composed of a positive and negative lead on the anode and cathode respectively. When a voltage is applied, the p-n junction of the diode begins to conduct. When the diode reaches a certain voltage threshold, the voltage regulation ceases and the reverse current flow, or the zener current, begins to flow. This process is known as the zener breakdown. The diode stays in this state until the voltage drops below the breakdown voltage and the original current flow resumes. The zener voltage point of the SML4729-E3/61 is 49.3V.

The SML4729-E3/61’s low reverse leakage current and high zener breakdown voltage make it an optimal choice for use in many consumer electronics applications. It is also capable of withstanding a wide range of temperatures, up to +175°C and -65°C. Additionally, the diode is available in a variety of packages and can be easily integrated into existing designs.
