SE20PB-M3/85A is a type of diodes which is a semiconductor device made of silicon or germanium, which allows electric current to pass in one direction and blocks it in the other. It is used for a variety of applications, mostly for purposes of rectification or rectifying the voltage in order to convert alternating current (AC) to direct current (DC). This type of diode is usually used for higher-power applications, such as electrical power transmission, motor control, and inverters.These diodes come in several sizes and voltage ratings, from 75 volts to 850 volts. The SE20PB-M3/85A is a single diode with a maximum continuous forward current of 20A, and a peak-inverse voltage rating of 850 volts. It is used in a variety of applications, including lighting panel controls, over-voltage protection circuits, high-efficiency switching 4V converters, and single-phase generators.The working principle of a diode is based on the fact that it only allows current to flow in one direction, but not in the other direction. This is achieved by a voltage-dependent rectifying effect, which is caused by the presence of a depletion region that blocks current flows in the reverse direction. The depletion region occurs at the junction between the p-type and n-type semiconductors of the diode. When a forward biased voltage is applied across the diode, electrons from the n-type layer are attracted to the more positively charged p-type layer, thus forming the depletion region in the middle, known as the barrier potential. When a reverse bias voltage is applied, the electric field at the depletion region prevents the electrons from crossing over, and thus blocks any current from flowing in the reverse direction. The SE20PB-M3/85A is especially useful in power systems because of its excellent performance under high currents and voltage. Its operating temperature is between -55°C and 125°C, giving it a wide range of applications. It\'s low forward voltage drop, low reverse leakage current, and low forward recovery time, mean that it is ideal for use in a variety of power rectification systems. The SE20PB-M3/85A is also used in automotive applications, as it stands up to the environmental conditions present in cars. It can also be used in domestic appliances, LED lighting, battery chargers, and other consumer electronics.The SE20PB-M3/85A is available in both axial-lead and surface-mount packaging, making it easy to use in various applications. It is also designed to meet the strict safety requirements of IEC, UL, CSA, and other related agencies, making it a reliable and safe choice for many applications.In conclusion, the SE20PB-M3/85A single diode is a highly reliable and versatile device which is widely used in a variety of power rectification systems. It is capable of handling high currents and voltages, and its stringent safety requirements make it ideal for a variety of applications. Its wide operating temperature range and availability in two different packaging options add to its versatility.
