// MBR base
"MBR1045CT" -> "MBR"
// TVS voltage
"SMBJ15A" -> "SMBJ"
"SMAJ24CA" -> "SMAJ"
// Schottky
"SS14" -> "SS"
"SK34" -> "SK"
// Transistors - specific series
"2N7002" -> "2N7002" // MOSFET
"2N3904" -> "2N"
// MMBT
"MMBT3904" -> "MMBT"
// Signal diodes

"1N914" -> "1N914"
// Rectifier series
"1N4007" -> "1N4xxx"
"1N5408" -> "1N5xxx"
Replacement Logic
// Rectifier voltage upgrade
"1N4007" can replace "1N4001-1N4007"
// MBR: same ratings, different package
"MBR1045CT" == "MBR1045S" (electrically)
// TVS: bidirectional can replace unidirectional
"SMBJ15CA" can replace "SMBJ15A"
// (But A cannot replace CA in AC applications)
// SS Schottky: same rating comparison
"SS14" vs "SS24" - same voltage, different current
// Transistor series
"MMBT3904" == "2N3904" (different package)

Learnings & Edge Cases
- 2N7002 is a MOSFET: Despite the 2N prefix (usually transistors), 2N7002 is an N-channel MOSFET. Handler returns MOSFET type.
- YJ prefix: Yangjie uses YJ prefix for their branded versions of industry standard parts (YJ1N4007 = 1N4007).
- MBR naming: Format is MBR[current][voltage]. MBR1045 = 10A, 45V. MBR2545 = 25A, 45V.
- TVS polarity: A suffix = unidirectional, CA suffix = bidirectional. Critical distinction for circuit protection.
- SS/SK current: First digit is current (1-5A). SS14 = 1A/40V, SS34 = 3A/40V.
- Check suffix ordering: When extracting packages from SS/SK, check longer suffixes (FL) before shorter (L).
- Bridge rectifier series: YJB and YJDB are similar bridge rectifiers. YJDB typically in DIP package.
- 1N series signal vs rectifier: 1N4148 is a signal diode (different from 1N4xxx rectifiers). Check specific pattern first.
