10 A per leg, 60 V blocking — the OR-ing and rail-protection workhorse
The RB088T-60NZC9 is a dual common-cathode Schottky rectifier from ROHM, rated 10 A average rectified current per diode at 60 V reverse voltage. Forward drop is 830 mV at 5 A — a reasonable trade-off for the ultra-low reverse leakage (3 µA at 60 V) that ROHM flags as the part's defining characteristic. In a TO-220FN full-pack (isolated tab) through-hole package, it bolts directly to a heatsink without an insulating pad — the tab is electrically isolated, so you can share a common heatsink across multiple devices in a bridge or OR-ing array without worrying about shorting the cathodes.
That is the absolute ceiling — the thermal design target should stay well below it. With 10 A per diode and 830 mV Vf at 5 A, conduction loss at full load is roughly 8.3 W per diode. The TO-220FN's junction-to-case thermal resistance (not listed here but typically 2–3°C/W for this package) determines how much heatsink you need to keep Tj under 125°C for reliability margin. The fast recovery spec (<500 ns at >200 mA) is characteristic of Schottky diodes — they are majority-carrier devices with no stored charge, so recovery is essentially instantaneous. The <500 ns figure confirms this is a standard-speed Schottky, not a hyper-fast SiC or GaN part. It handles 50/60 Hz line rectification and low-frequency switching without issue.
Active production, ROHS3 — sourcing posture
The common-cathode configuration in a single TO-220FN package saves board space and reduces part count compared to two discrete Schottkys. If your layout calls for a dual common-anode instead, that is a different ROHM order code — verify the pinout before committing the PCB.
