60 A dual-Schottky in a TO-247-3 — what the numbers mean
The 30 V reverse voltage rating suits 12 V and 24 V rails with margin, and the 4 mA reverse leakage at 30 V is typical for a Schottky of this die size.
Through-hole mounting and thermal management
The TO-247-3 is a through-hole package with a large metal tab for heatsink attachment. It does not go through a reflow oven — it is hand-soldered, wave-soldered, or pressed into a socket. The tab is the cathode common terminal; the two anode pins carry the individual diode connections. No MSL rating applies to through-hole parts of this class, so no bake-before-reflow concern.
