The RBR20T30ANZC9 is a Schottky barrier diode from ROHM Semiconductor, configured as a 1 Pair Common Cathode in a single TO-220FN package. It is rated for 10 A average rectified current per diode and a maximum reverse voltage of 30 V. Reverse leakage is 200 µA at the rated 30 V reverse voltage and 150°C junction temperature — the leakage doubles the thermal burden at high ambient, so the heatsink must account for it. The Fast Recovery classification (≤ 500 ns, > 200 mA Io) confirms this is a standard-speed Schottky, not an ultrafast or SiC device — suitable for line-frequency rectification and moderate-frequency switching up to a few tens of kHz.
Housed in a TO-220-3 Full Pack (TO-220FN) through-hole package, the fully molded case provides electrical isolation between the tab and the heatsink — no insulating pad or washer is needed when mounting to a grounded chassis or heatsink. The three leads are standard 0.100-inch pitch, compatible with 0.040-inch diameter PCB holes. The through-hole mounting requires a soldering iron or wave-solder profile; the large tab area conducts heat to the board or external heatsink. Junction temperature is rated to 150°C, so the thermal interface must keep the junction below this under full load.
