D471N90TXPSA1 Application Field and Working Principle

Diodes - Rectifiers - Single: A diode is an electronic component that, when biased in the forward direction, allows the flow of electric current through it, while blocking it in the reverse direction. The diode itself is usually a semiconductor material, typically silicon or germanium, which has been doped with impurities to achieve the desired type of electrical behavior. The most common type of diode is the single-junction (or single-pin) diode, in which one p-type material is sandwiched between two n-type materials. The single-junction diode is characterized by its voltage drop (Vf) and its maximum current that can be passed through it (If).The D471N90TXPSA1 is a single-junction, ultra-fast-recovery rectifier diode and is used in a variety of applications, such as power supplies, relay and solenoid drivers, lamp drivers, and EMI suppression. Its rated maximum reverse voltage is 90 volts and its rated surge forward current is 350 amperes. The D471N90TXPSA1 is designed to rectify high frequency and high amplitude alternating current signals. It uses a combination of forward and reverse-biased junctions to perform the diode rectification. In the forward bias, the diode acts as a low resistance pathway (or “short circuit”) between its positive and negative terminals and facilitates the flow of current. Conversely, in the reverse bias, the diode acts as an open circuit, blocking current from flowing. The D471N90TXPSA1 also has a reverse recovery time of less than 4 nanoseconds, allowing it to efficiently switch high frequency signals, such as those commonly encountered in power electronics applications.The D471N90TXPSA1 is also notable for its relatively low voltage drop and high reverse current capability. Its rated voltage drop is only 0.8 volts, and its rated maximum reverse current is 200 amperes. This enables the diode to substantially reduce power consumption in a wide array of applications. Furthermore, the diode is designed to dissipate low to moderate levels of heat in order to maintain thermal stability and reduce the risk of thermal runaway.The D471N90TXPSA1 is a versatile, high-performance diode that is capable of meeting the needs of a wide range of applications. Its features, such as its fast recovery time, low voltage drop, and high reverse current capability, make it a reliable and cost-effective solution for many rectification tasks.
