## Series Extraction Rules

The handler extracts series using these patterns:

| Pattern | Extracted Series |
|---------|------------------|
| PSMN* | "PSMN" |
| PSMP* | "PSMP" |
| PMV* | "PMV" |
| BSS* | "BSS" |
| 2N7002* | "2N7002" |
| PMBT* | "PMBT" |
| PBSS* | "PBSS" |

| BAVxx* | Specific (e.g., "BAV99") |
| BATxx* | Specific (e.g., "BAT54") |
| BZXxx* | Specific (e.g., "BZX84") |
| 74family* | Family (e.g., "74LVC", "74AHC") |
| PCA* | "PCA" |
| PCF* | "PCF" |
| PTN* | "PTN" |

---

## Package Code Extraction Logic

### Step 1: Check for Comma-Separated Suffix

```java
// Nexperia uses ,215, ,315, etc. for tape & reel packaging
if (mpn.contains(",")) {
    String suffix = mpn.substring(mpn.indexOf(',') + 1);
    // Lookup in NEXPERIA_PACKAGES map
}
```

### Step 2: Series-Specific Extraction

**Power MOSFETs (PSMN/PSMP):**
- Extract letter suffix after last digit
- T=LFPAK56, U=LFPAK88, V=LFPAK33, B=SOT754, L=TO-220

**Small Signal (PMV/BSS/2N7002):**
- Extract suffix after last digit
- Lookup in package map or return default SOT23

**Transistors (PMBT/PBSS):**
- Single letter suffix after grade letter = default SOT23
- Multi-letter suffix = lookup in map

**Zener Diodes (BZX):**
- BZX84 = SOT23
- BZX384 = SOD323
- BZX55/79 = DO-35
- BZX85 = DO-41

**Signal Diodes (BAV/BAS/BAT):**
- Most default to SOT23

**Schottky Rectifiers (PMEG):**
- Suffix-based: AEH=SOD123, AED=SOD323F, BEA=SOD128

**ESD Protection (PESD):**
- BL=SOD882, BA=SOD323, UB=SOT23, UD=SOT323

**Logic ICs (74xxx):**
- GW=SOT353, GM=XSON6, BQ=DHVQFN, PW=TSSOP, D=SO14
- Also handles underscore format: 74HC00_D

## Official Replacement Rules

The handler supports `isOfficialReplacement()` for:

### Logic ICs
- Same function number across families are compatible
- HCT is backward compatible with HC
- Same family, different packages are compatible

### Transistors
- PMBT2222A, 2N2222, PN2222 are equivalent (base "2222")
- PMBT3904 and 2N3904 are equivalent
- PMBT3906 and 2N3906 are equivalent

### MOSFETs
- Same base part, different package = compatible
- e.g., PSMN013-30YL and PSMN013-30YT (same specs, different packages)

---

## Handler Implementation Notes

### MPN Normalization

```java
// Remove tape & reel suffix before pattern matching
private String normalizeForMatching(String mpn) {
    if (mpn.contains(",")) {
        return mpn.substring(0, mpn.indexOf(','));
    }
    return mpn;
}
```

### Pattern Matching

The handler overrides `matches()` with explicit checks to avoid cross-handler false matches. It does NOT fall back to the PatternRegistry default implementation.

### Supported Types Use Set.of()

```java
return Set.of(
    ComponentType.MOSFET,
    ComponentType.TRANSISTOR,
    ComponentType.DIODE,
    ComponentType.IC,
    ComponentType.MOSFET_NEXPERIA,
    ComponentType.BIPOLAR_TRANSISTOR_NEXPERIA,
    ComponentType.ESD_PROTECTION_NEXPERIA,
    ComponentType.LOGIC_IC_NEXPERIA
);
```

## Related Files

- Handler: `manufacturers/NexteriaHandler.java` (note: typo in filename)
- Component types: `MOSFET_NEXPERIA`, `BIPOLAR_TRANSISTOR_NEXPERIA`, `ESD_PROTECTION_NEXPERIA`, `LOGIC_IC_NEXPERIA`

---

## Learnings & Quirks

### Handler Filename Typo
- The file is named `NexteriaHandler.java` but the manufacturer is **Nexperia**
- This is documented in the class-level Javadoc comment
- All ComponentTypes use the correct "NEXPERIA" suffix

### Comma-Separated Package Codes
- Unlike most manufacturers, Nexperia uses comma-separated suffixes (,215, ,315)
- These MUST be stripped before pattern matching
- The comma suffix encodes both package AND tape/reel configuration

### Logic IC Families
- When extracting logic family, check longer prefixes first: AHCT before AHC, LVCH before LVC
- The `extractLogicFamily()` method iterates through families in correct order

### Package Extraction Complexity
- Different series have completely different package encoding schemes
- PMEG uses full suffix codes (AEH, AED), while PSMN uses single letters (T, U, V)
- BZX series encodes package in the series name itself (BZX84 = SOT23)

### Transistor Equivalents
- PMBT2222A = 2N2222A = PN2222A (same transistor, different packages)
- The handler correctly identifies these as equivalent in `isOfficialReplacement()`

### No ManufacturerComponentTypes
- `getManufacturerTypes()` returns `Collections.emptySet()`
- All types are standard ComponentType enums

### Pattern Registration
- Each pattern is registered for BOTH base type and Nexperia-specific type
- Example: `MOSFET` and `MOSFET_NEXPERIA` both get the PSMN pattern
