Additional Details:

The RRE02VSM4S comes in a compact surface-mount package (typically a SOD-123 or similar). Key specifications include a repetitive peak reverse voltage (VRRM) of around 200V, a forward current (IF) of about 1A to 2A depending on the temperature, and a typical reverse recovery time (trr) of less than 35ns. Its low junction capacitance also helps in reducing switching losses at higher frequencies. This diode is designed for automated assembly, simplifying the manufacturing process.
