At 8 A per diode, the 500 mV Vf is a typical figure for a 40 V Schottky in this current range. That translates to about 4 W conduction loss per diode at full rated current — manageable with a heatsink on the TO-220 tab, but the thermal design needs to account for both diodes conducting simultaneously. The reverse leakage of 700 µA at 40 V is worth noting for standby or low-load conditions: at elevated junction temperatures leakage climbs, so derate the effective current if the ambient is above 85°C.","metaTitle":"STPS16L40CT Schottky Diode, 40V 16A Common Cathode TO-220","metaDescription":"STPS16L40CT Schottky rectifier, 40V Vr, 16A total (2x8A), 500mV Vf at 8A, TO-220-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS16","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TO-220","Current - Reverse Leakage @ Vr":"700 µA @ 40 V","Voltage - DC Reverse (Vr) (Max)":"40 V","Operating Temperature - Junction":"150°C (Max)","Voltage - Forward (Vf) (Max) @ If":"500 mV @ 8 A","Current - Average Rectified (Io) (per Diode)":"8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0ba2f3e012da7855837921b50cd6c635.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS16L40CT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy STPS16L40CT?","answer":"Since the STPS16L40CT is obsolete, it is not available through the factory channel.
