The FR70B05 rectifier, part of the single diode family, is widely used for general purpose power rectification applications such as AC/DC voltage adapters and power inverters.It is based on a high speed Schottky barrier diode which works as a switch in power supplies and converters applications, providing fast switching and low power loss.The FR70B05 rectifier, as part of the single diode family, starts to rectification with anode and cathode connecting to AC power input from either a transformer or mains supply. The rectifier then only allows AC signal to flow in a single direction, blocking any voltage from returning to the source.The working principle of the FR70B05 rectifier is relatively simple. It takes benefit from the electrical behavior of a diode, which behaves as an open circuit during the normal peak of the AC cycle. Then, for the negative peak of the AC cycle, the diode acts as a short circuit and carries electrical current from the source to the load.The FR70B05 rectifier is a step-up or step-down rectifier, depending on its usage. It is normally used as a step-down rectifier to convert AC to DC, while it can be used as a step-up rectifier in dc-ac inverters to convert the input DC to desired AC voltage.The FR70B05 rectifier provides a simple and cost-effective way to rectify component power and offers other advantages such as fast reverse recovery time and low forward voltage drop, as well as very low static power losses due to its low reverse leakage current. It also has a low storage time value, meaning it can switch quickly, which is important in high current applications.In the automotive and industrial fields, the FR70B05 rectifier is mainly used for on-board vehicular power applications such as DC power supply for audio systems and automotive microcontrollers, as well as in power supply, converter and inverter applications.The FR70B05 rectifier offers features such as wide operating temperature range from -40°C to +105°C and halogen-free, RoHS-compliant plastic packages, which provide flame retardance and environmental protection for an efficient, safe and reliable operation.The FR70B05 rectifier also offers a wide input voltage range from 20 V to 80 V, a Schottky barrier diode with a forward voltage drop of 500 mV which provides low power loss and a fast reverse recovery time of 1.5 μs. It guarantees a high voltage withstand withstanding up to 35 V and has a surge power rating of 8000 pF.The FR70B05 rectifier is suitable for a variety of applications across different industries such as automotive, industrial, telecommunication and healthcare. It helps to provide reliable performance, cost-efficiency and a long product life.Overall, the FR70B05 rectifier is a reliable and cost-effective single diode for general purpose power rectification applications, mainly due to its ability to effectively block any current from returning to the source and providing a high voltage withstand.
