Handler Implementation Notes
Issues Found in Current Handler
- HashSet usage (line 41): Should use
Set.of()orEnumSetfor immutability - Series extraction order bug: Checks
IRFbeforeIRFP/IRFB, so "IRFP4560" returns "IRF" - Missing patterns: No patterns for XMC MCUs, OptiMOS (IPP, BSC series), despite being in getSupportedTypes()
- Package extraction incomplete: Only handles legacy IRF suffix codes, not new prefix-based system
Series Extraction Fix
// WRONG - "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
// 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
// OptiMOS/StrongIRFET (should be added)
registry.addPattern(ComponentType.MOSFET, "^IP[PBDIWTA][0-9].*");
registry.addPattern(ComponentType.MOSFET, "^SP[PBDIW][0-9].*");
registry.addPattern(ComponentType.MOSFET, "^BS[CZKOA][0-9].*");
// XMC Microcontrollers (should be added)
registry.addPattern(ComponentType.MICROCONTROLLER_INFINEON, "^XMC[14][0-9]{3}.*");
registry.addPattern(ComponentType.MCU_INFINEON, "^XMC[14][0-9]{3}.*");
// CoolSiC MOSFETs (should be added)
registry.addPattern(ComponentType.MOSFET_INFINEON, "^IM[WZ][0-9]+R[0-9]+.*");

Learnings & Edge Cases
- IRF acquisition: Infineon acquired International Rectifier in 2015, inheriting the IRF/IRL nomenclature
- Dual naming: Many parts have both old IRF names and new Infineon names (cross-reference needed)
- Package prefix vs suffix: Legacy IRF uses suffix (IRFZ44N), new OptiMOS uses prefix (IPP060N06N)
- Logic level: IRL series has lower gate threshold voltage (Vgs < 5V) for direct MCU drive
- PbF suffix: Lead-free (RoHS compliant) designation on some parts
- -7 suffix: Sometimes indicates 7-pin variant (e.g., D2PAK-7)
