Handler Implementation Notes
Issues Found in Current OnSemiHandler
- HashSet usage (line 39): Uses mutable
HashSet instead of Set.of() or EnumSet for immutability
- Limited MOSFET patterns: No patterns for NTD, FQP, FDP series MOSFETs
- Limited transistor patterns: No patterns for 2N, MMBT, MPSA series transistors
- Missing NCP regulator patterns: Only covers MC78xx/MC79xx, missing NCP series
- Package extraction logic: Only handles diode packages, missing MOSFET/transistor package codes
- Series extraction incomplete: Does not extract series for MOSFETs or transistors

Learnings & Edge Cases
- Fairchild acquisition: ON Semiconductor acquired Fairchild in 2016, inheriting FQP/FDP/FDD nomenclature
- Motorola heritage: MC78xx, MC79xx, MUR, MBR series come from Motorola semiconductor division
- JEDEC standards: 2N and 1N prefixes follow JEDEC numbering (no encoded specs in number)
- Logic level: "L" suffix indicates logic-level gate threshold (~2.5V Vgs max)
- Automotive grade: NCV prefix indicates AEC-Q100/Q101 qualified automotive parts
- Cross-reference needed: Many parts have equivalents across ON Semi, Fairchild, and other sources
- Package suffix variations: CT vs T both mean TO-220; DT means DPAK

377## Handler Implementation Notes
378
379### Issues Found in Current OnSemiHandler
380
3811. **HashSet usage** (line 39): Uses mutable `HashSet` instead of `Set.of()` or `EnumSet` for immutability
3822. **Limited MOSFET patterns**: No patterns for NTD, FQP, FDP series MOSFETs
3833. **Limited transistor patterns**: No patterns for 2N, MMBT, MPSA series transistors
3844. **Missing NCP regulator patterns**: Only covers MC78xx/MC79xx, missing NCP series
3855. **Package extraction logic**: Only handles diode packages, missing MOSFET/transistor package codes
3866. **Series extraction incomplete**: Does not extract series for MOSFETs or transistors

464## Learnings & Edge Cases
465
466- **Fairchild acquisition**: ON Semiconductor acquired Fairchild in 2016, inheriting FQP/FDP/FDD nomenclature
467- **Motorola heritage**: MC78xx, MC79xx, MUR, MBR series come from Motorola semiconductor division
468- **JEDEC standards**: 2N and 1N prefixes follow JEDEC numbering (no encoded specs in number)
469- **Logic level**: "L" suffix indicates logic-level gate threshold (~2.5V Vgs max)
470- **Automotive grade**: NCV prefix indicates AEC-Q100/Q101 qualified automotive parts
471- **Cross-reference needed**: Many parts have equivalents across ON Semi, Fairchild, and other sources
472- **Package suffix variations**: CT vs T both mean TO-220; DT means DPAK
