The BAS321-QF is a general purpose, power, and switching diode manufactured by Nexperia, and is packaged in an SOD323/SOD2 package. It offers a single PN junction device with low forward voltage drop, low reverse leakage current, and high surge avalanche capability. The BAS321-QF is designed for general purpose switching applications in low power circuits. Its high surge current rating makes it ideal for rectification of low-power AC/DC power supplies or for general signal diode applications. Its low thermal resistance junction can sustain high di/dt loads, making it the ideal choice for low-power power switching needs. It features a maximum forward voltage drop of 1V, a continuous forward current rating of 200 mA, and an FT rating of 250V.
