A true equivalent must satisfy these 5 pillars:
When in doubt for a power supply MOSFET, overspec ( V_DSS ) by 20% and ( I_D ) by 50%, but never overspec ( Q_g ) beyond 30% of the original. all mosfet equivalent book datasheet
While you won’t find one book containing every MOSFET ever made (there are over 50,000+ active part numbers), the exists in the form of master cross-reference indexes (like those from NTE, ECG, or TCE) and digital aggregators (like DatasheetArchive, Alldatasheet, or Mouser). A true equivalent must satisfy these 5 pillars:
Introduction: The Myth of the Single Universal Book For decades, electronics repair technicians and hobbyists have dreamed of a single, mythical volume: "The All MOSFET Equivalent Book." In reality, such a book does not exist as a singular, published tome. Instead, the concept represents a methodology —a combination of cross-reference guides, parametric databases, and datasheet analysis used to find a replacement for a missing or obsolete MOSFET. 000+ active part numbers)
