# 3PEAK Manufacturer Skill
## MPN Structure
3PEAK MPNs follow this general structure:
```
TP[SERIES][VARIANT]-[PACKAGE][OPTIONS]
│ │ │ │ │
│ │ │ │ └── Optional: voltage options (-5, -33)
│ │ │ └── Package code (TR, QR, MR, DR)
│ │ └── Part number within series
│ └── Series (1xxx=Op-Amp, 2xxx=Precision, 5xxx=ADC, 7xxx=LDO, 1xx=Current Sense)
└── 3PEAK prefix
```
### Example Decoding
```
TP1541-TR
│ │ │
│ │ └── TR = SOT-23 package, Tape & Reel
│ └── 1541 = Op-Amp series
└── TP = 3PEAK prefix
TP7150-MR-33
│ │ │ │
│ │ │ └── -33 = 3.3V output option
│ │ └── MR = MSOP package
│ └── 7150 = LDO regulator series
└── TP = 3PEAK prefix
```

## Handler Implementation Notes
### Component Type Detection
The handler distinguishes between similar-looking part numbers:
```java
// Op-amps have 4-digit part numbers (TP1541, TP2111)
// Current sense amps have 3-digit part numbers (TP181, TP182)
// Comparators share prefix but have specific part numbers (TP1561, TP2345)
// CRITICAL: Comparators must be excluded from op-amp detection
if (COMPARATOR_PATTERN.matcher(mpn).matches()) {
return false; // Not an op-amp
}
```
### Package Code Extraction
```java
// Package code is the 2-letter suffix after the part number
// TP1541-TR -> TR = SOT-23
// TP7150MR -> MR = MSOP (no hyphen variant)
// Remove voltage options before extracting package
String baseMpn = upperMpn.replaceAll("-[0-9]+$", "");
```
### Series Extraction
```java
// Current sense amps: TP18x -> "TP18"
// Standard 4-digit: TP1541 -> "TP1"
// Standard 4-digit: TP7150 -> "TP7"
if (upperMpn.matches("^TP18[0-9].*")) {
return "TP18"; // Special case for current sense
}
```

## Series Descriptions
| Series | Description |
|--------|-------------|
| TP1 | Op-Amps/Comparators |
| TP2 | Precision Op-Amps/Comparators |
| TP5 | ADCs |
| TP7 | LDO Regulators |
| TP18 | Current Sense Amplifiers |

## Voltage Options (LDO Regulators)
LDO regulators often have voltage options encoded as suffix:
| Suffix | Output Voltage |
|--------|---------------|
| -5 | 5.0V |
| -33 | 3.3V |
| -25 | 2.5V |
| -18 | 1.8V |
| -12 | 1.2V |

## Learnings & Edge Cases
- **3-digit vs 4-digit parts**: TP181 (3-digit) is current sense amplifier, TP1541 (4-digit) is op-amp
- **Comparator exclusion**: TP1561 and TP2345 are comparators, NOT op-amps, despite similar prefixes
- **Package code hyphen**: Both `TP1541-TR` and `TP1541TR` formats are valid
- **Voltage option suffix**: `-33` means 3.3V output, not package variation
