Nexperia Manufacturer Skill

Use this skill when working with Nexperia components - discrete semiconductors including transistors, MOSFETs, diodes, ESD protection devices, and logic ICs.

Handler Location

• Handler: src/main/java/no/cantara/electronic/component/lib/manufacturers/NexteriaHandler.java
• Tests: src/test/java/no/cantara/electronic/component/lib/handlers/NexteriaHandlerTest.java

NOTE: The filename uses "Nexteria" which is a typo - the manufacturer is "Nexperia".

Company Background

Nexperia was spun off from NXP Semiconductors in 2017. The company inherited:

• NXP Standard Products division
• Philips Semiconductors discrete components (acquired by NXP in 2006)
• Wide portfolio of transistors, diodes, MOSFETs, ESD protection, and logic ICs

Example Usage

NexteriaHandler handler = new NexteriaHandler();
PatternRegistry registry = new PatternRegistry();
handler.initializePatterns(registry);

// Detect component type
handler.matches("PMBT2222A,215", ComponentType.TRANSISTOR, registry);  // true
handler.matches("PMBT2222A,215", ComponentType.BIPOLAR_TRANSISTOR_NEXPERIA, registry);  // true

// Extract package code
handler.extractPackageCode("PMBT2222A,215");  // "SOT23"
handler.extractPackageCode("BZX84-C5V1");     // "SOT23"
handler.extractPackageCode("PSMN3R5-30YLT");  // "LFPAK56"

// Extract series
handler.extractSeries("PMBT2222A,215");  // "PMBT"
handler.extractSeries("74LVC08D");       // "74LVC"
handler.extractSeries("PESD5V0S1BL");    // "PESD"

Cross-Manufacturer Equivalents

| Nexperia | Equivalent | Notes | |----------|------------|-------| | PMBT2222A | 2N2222, MMBT2222 | SOT23 version | | PMBT3904 | 2N3904, MMBT3904 | General purpose NPN | | PMBT3906 | 2N3906, MMBT3906 | General purpose PNP | | BC547 | BC107, BC171 | General purpose NPN | | 2N7002 | BSS138, Si2302 | Small signal N-ch MOSFET | | BAV99 | BAS19 pair | Dual series diode | | 74HC00 | SN74HC00, TC74HC00 | Quad NAND gate |

Replacement Rules

1. Logic ICs: 74HCT is backward compatible with 74HC (accepts TTL levels)
2. Transistors: PMBT, MMBT, and 2N series with same number are equivalent
3. MOSFETs: Same base part number with different package suffix are interchangeable (e.g., PSMN3R5-30YLT vs PSMN3R5-30YLU)
4. Zeners: Same voltage rating across BZX84/BZX55/BZX79 are functionally equivalent (different packages)

Learnings & Quirks

Comma Suffix Handling

• Nexperia uses ,215, ,315, etc. as tape & reel packaging codes
• The handler normalizes these before pattern matching
• Package extraction uses the comma suffix to determine the actual package

BC Series Numbering

• BC5xx (BC546-BC550) are low noise NPN
• BC5x7 (BC547, BC557) are complementary pairs
• BC8xx are SMD versions (BC846 = BC546 in SOT23)

Logic IC Family Hierarchy

When checking for 74-series families, check longer prefixes first:

1. AHCT before AHC
2. LVCH before LVC
3. HCT before HC

2N7002 vs BSS138

Both are popular small signal N-channel MOSFETs from Nexperia:

• 2N7002: 60V, 115mA, lower Rds(on)
• BSS138: 50V, 220mA, higher current capability

Adding New Patterns

When adding support for new Nexperia component lines:

1. Add patterns to initializePatterns() for both base type and Nexperia-specific type
2. Add explicit checks to matches() method to prevent cross-handler false matches
3. Add package code mappings for any new suffix formats
4. Add series extraction logic
5. Add comprehensive tests for new patterns

Example:

// In initializePatterns()
registry.addPattern(ComponentType.DIODE, "^NEW_SERIES[0-9].*");

// In matches()
boolean isNewSeries = normalizedMpn.matches("^NEW_SERIES[0-9].*");
if (type == ComponentType.DIODE && isNewSeries) {
    return true;
}
