Details	Datasheets BAT54A datasheet1 Oct 2022 · 1–4, 6	Differences & datasheets Check power dissipation when both diodes conduct. Verify reverse-voltage margin, forward drop, leakage, surge current, and temperature for the actual circuit. Check the complete package drawing and land pattern or lead spacing. Recovery behavior over temperature, parasitics, thermal layout, and qualification equivalence are not fully matched. BAT54 datasheetDS11005 Rev. 34-2, Nov 2023 · 1–2; package outline	—	—
