Handler Implementation Notes

Issues Found in Current Handler

1. HashSet usage (line 61): Should use Set.of() or EnumSet for immutability
2. Missing TRANSISTOR in getSupportedTypes(): Patterns exist for 2SC/2SA but type not in supported set
3. Missing base IC type in getSupportedTypes(): Patterns for IC (IGBTs, motor drivers, optocouplers) exist but base IC not declared
4. Package extraction incomplete: Only handles TPC/TPH/TMP, missing TK, TLP, SSM, TB, 2SC/2SA series
5. Series extraction incomplete: Missing TLP, 2SC, 2SA, TB series extraction
6. extractSeries returns empty for optocouplers: TLP series not handled

Package Extraction Fix

// Add TK series package extraction
if (upperMpn.startsWith("TK")) {
    // TK024N60Z1 - package in suffix after generation
    if (upperMpn.contains("Z")) return "TO-220SIS";
    if (upperMpn.endsWith("L") || upperMpn.endsWith("LQ")) return "DPAK";
    if (upperMpn.endsWith("S")) return "D2PAK";
}

// Add TLP optocoupler package extraction
if (upperMpn.startsWith("TLP")) {
    if (upperMpn.contains("SO6L") || upperMpn.contains("S06L")) return "SO-6";
    if (upperMpn.matches(".*\\(.*\\).*")) {
        // Has parentheses - likely SOP variant
        return "SOP-4";
    }
    return "DIP-4"; // Default for TLP
}

// Add SSM small signal package extraction
if (upperMpn.startsWith("SSM")) {
    if (upperMpn.endsWith("TU")) return "UFM";
    if (upperMpn.endsWith("F")) return "S-Mini";
    if (upperMpn.endsWith("FU")) return "USM";
}

// Add TB motor driver package extraction
if (upperMpn.startsWith("TB")) {
    if (upperMpn.contains("FNG")) return "SSOP24";
    if (upperMpn.contains("AFG")) return "QFN";
    if (upperMpn.contains("PG")) return "HTSSOP";
}

Series Extraction Fix

// Add TLP optocoupler series
if (upperMpn.startsWith("TLP")) return "TLP Series";

// Add transistor series
if (upperMpn.startsWith("2SC")) return "2SC Series";
if (upperMpn.startsWith("2SA")) return "2SA Series";
if (upperMpn.startsWith("2SB")) return "2SB Series";
if (upperMpn.startsWith("2SD")) return "2SD Series";

// Add digital transistor series
if (upperMpn.startsWith("RN")) return "RN Series";
if (upperMpn.startsWith("RP")) return "RP Series";

// Add voltage regulator series
if (upperMpn.startsWith("TAR")) return "TAR Series";

Missing Pattern Registration

// 2SK JIS N-channel MOSFETs (legacy series, still common)
registry.addPattern(ComponentType.MOSFET, "^2SK[0-9].*");
registry.addPattern(ComponentType.MOSFET_TOSHIBA, "^2SK[0-9].*");

// Missing digital transistors
registry.addPattern(ComponentType.TRANSISTOR, "^RN[0-9].*[A-Z]?$");
registry.addPattern(ComponentType.TRANSISTOR, "^RP[0-9].*[A-Z]?$");

getSupportedTypes Fix

@Override
public Set<ComponentType> getSupportedTypes() {
    // Use Set.of() for immutability
    return Set.of(
        ComponentType.MOSFET,
        ComponentType.MOSFET_TOSHIBA,
        ComponentType.TRANSISTOR,           // ADD - patterns exist
        ComponentType.IC,                   // ADD - patterns exist
        ComponentType.IGBT_TOSHIBA,
        ComponentType.MOTOR_DRIVER_TOSHIBA,
        ComponentType.GATE_DRIVER_TOSHIBA,
        ComponentType.OPTOCOUPLER_TOSHIBA,
        ComponentType.VOLTAGE_REGULATOR,
        ComponentType.VOLTAGE_REGULATOR_TOSHIBA,
        ComponentType.MICROCONTROLLER,
        ComponentType.MICROCONTROLLER_TOSHIBA
    );
}

Learnings and Edge Cases

• JIS naming: 2SA/2SB/2SC/2SD follow Japanese Industrial Standard for transistors
• Complementary pairs: 2SC5200/2SA1943 are matched PNP/NPN pairs for audio amplifiers
• DTMOS: Digital Trench MOS technology for improved switching efficiency
• TLP numbering: 3-digit (TLP127) typically older, 4-digit (TLP3910) typically newer products
• hFE ranks: Transistors sorted by gain (O, P, Q, R, Y grades) - same base part, different gain bins
• Tape suffix variations: L, L1, L3 indicate different reel quantities
• Photocoupler variants: Same base number with different CTR grades (A, B, C, D, GB, GR, GC)
• Motor driver generations: TB66xx (older) vs TB67xx (newer brushed DC) vs TB9xxx (automotive)
• ARM MCU naming: TXZ family uses TMP prefix with core indicator (M for ARM, V for RISC-V)
