Diodes - Rectifiers - Arrays: BYQ42E-200Q Application Field and Working Principle

BYQ42E-200Q is a type of diode array, which is used as a rectifier in power electronics. It has two diodes connected in series – a PN Junction (with a forward voltage drop of 0.75-0.8 V) and an NPN Junction (with a forward voltage drop of 0.1-0.2V).The BYQ42E-200Q is a self-contained diode rectifier array with a maximum surge current of 8A and a voltage range of 30-500V. It has two terminals for anode and cathode connection, and has a low forward voltage drop and low reverse leakage current. It also features a low leakage current, reverse voltage protection, and an increased power rating. The BYQ42E-200Q is typically used in applications such as electronic motor drives, inverters, solar converters, protection circuits, power supplies, and other rectifier circuits that require high surge current capability, high power rating, low forward and reverse voltage drops, and low reverse leakage current. The working principle of the BYQ42E-200Q is quite simple. When a DC voltage is applied between its anode and cathode, the p-type and n-type diodes become forward and reverse biased, respectively. This results in current flow in the forward direction, wherein the voltage across the diode is 0.8V (for PN junction) and 0.2V (for NPN junction). The output of the diode rectifier array is a DC voltage that is proportional to the sum of the forward voltages across the two diodes in the array. Since the array has two diodes connected in series, the total forward voltage is always higher than the voltage of either of the two individual diodes. This results in higher efficiency, since the two diodes are sharing the load more evenly.The BYQ42E-200Q also features reverse voltage protection, which prevents excessive current flow in the reverse direction when the voltage exceeds a certain threshold. This also prevents damage to the circuitry in case of an unexpected spike or surge in current or voltage. In summary, the BYQ42E-200Q is an efficient and reliable rectifier array that is suitable for a wide range of applications. It is easy to use and offers an increased power rating, low forward and reverse voltage drops, low reverse leakage current, and reverse voltage protection.
