BAV21W-HE3-18

The BAV21W-HE3-18 single rectifier is a high current rectifier designed specifically for high power applications which require extremely low forward voltage drops and ultra-fast switching. This device can handle up to 18A in steady-state operation and can withstand a peak current of 30A for a limited amount of time. The device features a standard rated temperature range of -65 to 175°C and has a max peak junction temperature of 200°C.

With its low forward voltage drop and ultra-fast switching characteristics, the BAV21W-HE3-18 is ideal for use in high power converters, chargers, and motor controllers. It can also be used in power management applications such as DC/DC converters, battery charging and protection systems, and AC/DC converters. The device can be used in both AC and DC circuits, depending on the specific application.

The BAV21W-HE3-18 rectifier has a low reverse leakage current, making it suitable for use with low voltage switching applications such as notebook computer batteries and Point of Load converters. The device also operates at a higher temperature range than other single rectifiers, allowing for operation in a wider range of environmental conditions. The device is constructed using high frequency epoxy molds for improved thermal and mechanical stability.

Working principle: BAV21W-HE3-18 uses the theory of electron movement to build a bridge rectifier. In a traditional AC circuit, there is equal positive and negative voltage. The positive voltage is passed through the diode and it converts the AC to DC. The BAV21W-HE3-18 uses a combination of four diodes and uses a single power supply to convert the AC voltage to DC voltage. It also has a higher current capability due to its bridge construction, which allows it to handle higher current applications.

In addition, the device also has surge and transient suppression capabilities, which enable it to control the output voltage during a fault condition, reducing the chances of damage to downstream loads and components. This makes the device well suited for use in automotive environments and harsh industrial applications. The device is also RoHS compliant and meets UL and IEC safety standards.

Overall, the BAV21W-HE3-18 single rectifier is a powerful, reliable, and versatile device designed for demanding power management applications. Its low forward voltage drop and ultra-fast switching capabilities make it ideal for use in high power converters, chargers, and motor controllers. The device is also RoHS compliant and meets UL and IEC safety standards, making it a popular choice for automotive and industrial applications.
