Diodes are widely used in electronics applications, and particularly in the field of Zener diodes. Zener diodes are designed specifically for reverse-biasing, or “Zener-doping,” where the voltage and current applied to the diode are in opposite direction to the normal forward-biasing. The 1PGSMA4748 R3G is a Zener diode designed to be used in high-voltage applications. In this article, we will discuss the application field for the 1PGSMA4748 R3G, as well as its working principle. The 1PGSMA4748 R3G is a single-phased Zener diode with a maximum reverse breakdown voltage (VBR) of 547V. The device is based on planar technology, meaning that a metal layer is inserted between the P-type and N-type layers to act as a current limiter. The Zener diode is capable of dissipating up to 1.5W of power when used in a high-voltage application. It is available in three different package types: TO-220, SOT-223 and SOT-227. The 1PGSMA4748 R3G is ideal for applications where a high-voltage and current-limiting device is required. It is used in a variety of fields, including power supplies, overvoltage protection, surge protection and automotive electronics. The Zener diode is also well-suited for medical applications due to its high-voltage and high-current capabilities. The 1PGSMA4748 R3G can be used in both forward- and reverse-biased applications. In forward-biased applications, the Zener diode operates like a regular diode, allowing current to flow when a certain voltage is applied across it. In reverse-biased applications, the device acts like a voltage regulator, controlling the output voltage when connected in series with other components. The 1PGSMA4748 R3G works by utilizing the junction between the P- and N-type materials. When voltage is applied to the diode, the electric field created by the charge carriers causes electrons to move from the P to the N layer. This movement of current creates a depletion region near the junction, which prevents further current from flowing. When the applied voltage is greater than the breakdown voltage of the device, it can no longer sustain the electric field and the junction begins to conduct current. This effect is known as Zener Breakdown. In summary, the 1PGSMA4748 R3G is a single-phased Zener diode with a VBR of 547V. The device is well-suited for high-voltage and current-limiting applications, such as power supplies and surge protection. Its ability to be used in both forward- and reverse-biased applications makes it an ideal choice for a wide range of applications. The 1PGSMA4748 R3G utilizes the Zener breakdown effect to control the voltage when connected in series with another device.
