Selection Guidance

When selecting the MBRS540T3G, verify the forward voltage drop and thermal characteristics against your specific operating conditions. The 40V reverse voltage rating is suitable for low-voltage rails; for higher voltage applications, consider other series options. Ensure adequate PCB copper area for heat dissipation, as the SMC package relies on board thermal paths.
