The common-cathode pair shares the same cathode tab, which simplifies layout for center-tap secondary rectification or dual-output OR-ing where both anodes connect to separate windings or rails. ## Package and mounting — TO-247-3 through-hole Through-hole TO-247-3 with the metal tab as the common cathode. The tab is electrically live, so the heatsink must be isolated or the mounting hardware must use an insulating pad and shoulder washer. The three-lead form factor matches the standard TO-247 footprint used by many 150 V dual Schottkys — layout reuse across vendors is straightforward as long as the pin 1 assignment (anode 1, cathode common, anode 2) is verified against the existing PCB. ST lists the STPS40150CW as Active product status. RoHS compliance is standard for ST's current TO-247 Schottky portfolio — no separate exemption certificate needed for EU markets.","metaTitle":"STPS40150CW dual Schottky rectifier, 150 V 20 A TO-247","metaDescription":"STPS40150CW dual common-cathode Schottky rectifier, 150 V, 20 A per diode, 920 mV Vf at 20 A, TO-247-3.

The TO-220 body is smaller and the tab current rating is lower — it fits a lower-power board where the TO-247 package is overkill.
