The 300 µA reverse leakage at 90 V is a room-temperature figure; Schottky leakage doubles with every 10 °C rise, so at 125 °C junction the leakage current into the load dominates the standby budget and must be accounted for in the thermal design. The speed rating — fast recovery under 500 ns at over 200 mA — is the Schottky's natural switching behaviour: no stored minority carriers, so reverse-recovery charge is negligible. This makes the RB205T-90NZC9 a candidate for the secondary-side rectifier in a 50-100 kHz forward converter or the freewheeling diode in a buck converter where the switching edge is under 100 ns. ## Package and mounting — TO-220FN with full-pack isolation Housed in a TO-220-3 Full Pack (TO-220FN), the RB205T-90NZC9 is a through-hole device with the mounting tab fully encapsulated — no exposed metal pad. This eliminates the need for a mica insulator and thermal grease between the tab and the heatsink, simplifying the assembly step and reducing the thermal resistance path. The full-pack construction also provides electrical isolation between the tab and the heatsink, so a single common heatsink can be shared across multiple devices without isolation pads.","metaTitle":"ROHM RB205T-90NZC9 Schottky Diode, 15A, 90V, TO-220FN","metaDescription":"ROHM RB205T-90NZC9 Schottky diode, 15A average rectified per diode, 90V Vr, 780mV Vf at 7.5A, TO-220FN, active, ROHS3.
