"IRF" matches before "IRFP" is checked if (mpn.startsWith("IRF")) return "IRF"; if (mpn.startsWith("IRFP")) return "IRFP"; // Never reached for IRFP4560! // CORRECT - Check longer prefixes FIRST if (mpn.startsWith("IRFP")) return "IRFP"; // Specific series first if (mpn.startsWith("IRFB")) return "IRFB"; // Specific series first if (mpn.startsWith("IRFZ")) return "IRFZ"; // Specific series first if (mpn.startsWith("IRF")) return "IRF"; // General fallback last ``` ### Package Code Extraction ```java // Legacy IRF suffix-based if (mpn.matches(".*[0-9]N$")) return "TO-220"; if (mpn.matches(".*[0-9]S$")) return "D2PAK"; if (mpn.matches(".*[0-9]L$")) return "TO-262"; if (mpn.matches(".*[0-9]P$")) return "TO-247"; // New prefix-based (OptiMOS/StrongIRFET) if (upperMpn.startsWith("IPP") || upperMpn.startsWith("SPP")) return "TO-220"; if (upperMpn.startsWith("IPB") || upperMpn.startsWith("SPB")) return "D2PAK"; if (upperMpn.startsWith("IPD") || upperMpn.startsWith("SPD")) return "DPAK"; if (upperMpn.startsWith("IPW") || upperMpn.startsWith("SPW")) return "TO-247"; if (upperMpn.startsWith("IPI") || upperMpn.startsWith("SPI")) return "I2PAK"; if (upperMpn.startsWith("BSC")) return "SuperSO8"; if (upperMpn.startsWith("BSZ")) return "PQFN-3.3x3.3"; ``` ### Missing Pattern Registration ```java // OptiMOS/StrongIRFET (should be added)
