When looking for RB521CS-30 schottky barrier diode from ROHM, you may find an “A” suffix at the end of the part number, i.e. RB521CS-302RA.
- This “A” suffix calls out 100mA series.
Please note that RB521CS-302RA is inactive. You may consider using RB521CM-30T2R, instead. Here is the data sheet for part RB521CM-30T2R which gives quick reference to the part specifications.
