SBR545SAFQ-13

SBR545SAFQ-13 is a Schottky barrier rectifier diode in a surface-mount package used for power rectification in switch‑mode power supplies and DC‑DC converters.
Key points:
- SBR = Schottky Barrier Rectifier: low forward voltage drop and fast switching, aiding efficiency.
- 545 typically implies a 5 A class device with a nominal reverse rating around 40–45 V, but exact values depend on the -13 variant. Always confirm from the manufacturer’s datasheet.
- SAFQ-13 denotes the specific SMT package/revision and lead-free format.
- Common uses: rectification and freewheeling in SMPS, buck/boost converters, and OR-ing diodes.
How to get exact specs:
- look up the official datasheet for SBR545SAFQ-13 (manufacturer or distributor site) for VRRM, IF, VF, IFSM, TRR, and package footprint.
- verify pinout and recommendations for reflow soldering and thermal performance.

Two pins. It is a Schottky barrier rectifier diode (SBR), i.e., a two-terminal device (anode and cathode) used for low-forward-voltage- drop rectification.

SBR545SAFQ-13 is a Schottky barrier rectifier diode (high-speed, low forward drop; ~5 A, ~45 V class).
Common application areas:
- High-efficiency rectification in switch‑mode power supplies and DC‑DC converters
- Freewheeling/footnote diodes in switching regulators
- OR-ing and reverse-polarity protection for power rails
- Battery charging circuits
- Automotive and consumer electronics
- Solar power electronics and LED driver circuits requiring fast, low-loss rectification

I don’t have enough info to identify SBR545SAFQ-13’s package reliably. Please provide the manufacturer or a datasheet/link and I’ll confirm the package type.
