STMicroelectronics lists the STPS30L40CG as obsolete. ## Hand-solderable D2PAK — a maker-friendly note The D2PAK (TO-263) is a surface-mount package with a large exposed tab. It is hand-solderable with a decent iron and some flux — pre-tin the pad, reflow the tab with a hot-air station or a big tip, then tack the leads. No tiny pitch to worry about, and the tab doubles as the thermal path, so a good solder joint there matters for keeping junction temperature under the 150°C max.","metaTitle":"STPS30L40CG Schottky Diode, 40V 15A Common Cathode, D2PAK","metaDescription":"STPS30L40CG Schottky diode pair: 40V reverse, 15A per diode, 550mV Vf, fast recovery ≤500ns.
