The dual-diode common-cathode configuration fits center-tapped full-wave rectifiers and OR-ing arrays where the two anodes connect to separate AC or supply legs and the common cathode ties to the output bus. ## Switching speed and conduction loss Rated Fast Recovery ≤500 ns at >200 mA — this is a line-frequency rectifier, not a high-speed switching diode. For 50-60 Hz rectification the recovery time is irrelevant; for a 100 kHz boost converter the stored charge will cause significant reverse-recovery loss. Forward drop is 720 mV maximum at 15 A per diode — the conduction loss at half-rated current is 10.8 W per diode. At 30 A the Vf will be higher; the junction temperature must stay within the 150°C limit, which demands a low-thermal-resistance board layout with adequate copper area on the cathode tab. Reverse leakage is 10 µA at 30 V — this off-state current doubles roughly every 10°C above 25°C. At 125°C junction the leakage can reach several milliamps, adding to the thermal budget in elevated-temperature environments.","metaTitle":"ROHM RB228NS-30TL Schottky Diode, 30A, 30V, TO-263-3","metaDescription":"ROHM RB228NS-30TL dual common-cathode Schottky rectifier, 30A per diode, 30V reverse, 720mV Vf at 15A, TO-263-3 D²Pak.
