Diodes, often referred to as rectifiers, are one of the most widely used electronic components in the world. A single diode, such as a S1KBHR5G, is used when current needs to be directed in one direction only. In this article, we’ll take a look at the application field and working principle of the S1KBHR5G diode.The S1KBHR5G diode is a medium-power, fast-recovery diode with a voltage rating of 500V and is widely used in switch-mode power supplies. It is typically used for phase-control rectification, inverter free-wheeling, and DC chopper circuits. The fast-recovery feature is an important attribute as it helps to reduce power loss and electromagnetic interference (EMI). The device also exhibits low leakage current, which is beneficial in applications that require a low level of standby current.The inner workings of a diode can be explained using a simple circuit diagram. A diode is comprised of an anode and a cathode, connected to a resistor. When the diode is off, the resistor forms an open circuit, meaning current will not flow. When the diode is turned on, the resistor forms a closed circuit, and current will flow from the anode to the cathode.In the case of the S1KBHR5G diode, when a positive voltage is applied to the anode, electrons flow from the anode to the cathode, and the diode begins to conduct. This type of diode is referred to as an ‘on-state’ diode. When a negative voltage is applied to the anode, the diode will become reversed-biased, and cease to conduct. This type of diode is referred to as an ‘off-state’ diode.The typical applications of the S1KBHR5G diode can be divided into two main areas: AC to DC conversion and DC to AC conversion. The S1KBHR5G diode can be used in an AC to DC converter to produce a rectified DC voltage. This is often used in switching mode power supplies (SMPS), where an AC voltage is rectified and then filtered to produce a DC output voltage.The S1KBHR5G diode can also be used in DC to AC converters, such as inverters. In this application, a DC voltage is rectified and then filtered. This rectified, filtered DC voltage is then fed into an inverter circuit, where it is converted back into an AC voltage.In addition to its use in AC to DC and DC to AC converters, the S1KBHR5G diode is also used as a free-wheeling diode in various motor control applications. A free-wheeling diode is a special type of diode that is used to pass the current from the load to the source in alternate directions. This helps to prevent the motor from stalling, due to the generated inductive kick-back voltage, during a voltage surge.To summarise, the S1KBHR5G diode is a medium-power, fast-recovery diode, primarily used in SMPS, DC to AC converters, and motor control applications. Its fast-recovery feature helps to reduce power loss and EMI, and its low leakage current attribute is beneficial in applications that require a low level of standby current. The diode is most effective when used to direct current in one direction only.
