The RBR20T40ANZC9: The 620 mV forward voltage at 10 A is the conduction loss figure — at 10 A, each diode dissipates about 6.2 W, which the TO-220FN full-pack case must sink through the mounting tab. The 240 µA reverse leakage at 40 V is typical for a Schottky this size; it climbs with junction temperature, so the 150 °C Tj max sets the thermal budget for the heatsink. AEC-Q101 qualification means this part passed the automotive discrete stress tests: temperature cycling, high-temperature reverse bias, and ESD robustness per the AEC-Q101 appendix. The junction rating to 150 °C supports under-hood ambient conditions where the rectifier sees continuous conduction.
Through-hole TO-220-3 Full Pack, also called TO-220FN. The full-pack (isolated) tab means the back of the package is electrically isolated from the die — no insulating pad needed between the tab and the heatsink, which simplifies the mounting stack. The three leads are standard 0.100-inch pitch; the centre lead is the common cathode. Hot-air removal: preheat the board to 100 °C, then hit the leads with a 350 °C nozzle; the full-pack body soaks heat slower than a standard TO-220, so dwell a few seconds longer before lifting.
