Additional Details:

The BYG21K-HE3/TE has a maximum repetitive peak reverse voltage (VRRM) of 600V and a forward current (IF) of 2.0A. The fast reverse recovery time (trr), typically around 75ns, minimizes switching losses and improves overall circuit efficiency. The low forward voltage drop (VF), approximately 1.0V, reduces power dissipation. The high surge current capability ensures that the diode can withstand transient current spikes without damage. The glass-passivated junction enhances the device's reliability and stability. The AEC-Q101 qualification ensures the diode meets the stringent requirements for automotive applications. The device is housed in a DO-214AC (SMA) package, making it suitable for automated assembly processes. The HE3 suffix indicates an environmentally friendly component and the /TE suffix indicates tape and reel packaging. It's designed to operate over a wide temperature range, typically from -65°C to +175°C.
