MPN Structure

Yangjie MPNs follow industry-standard patterns:

Pattern Matching

"^YJ1N[0-9]{4}.*"

// MBR Schottky rectifiers
"^MBR[0-9]{4}.*"

// TVS diodes
"^SMBJ[0-9]+\\.?[0-9]*[AC]?.*"

Series Extraction

// YJ prefix removed for series
"YJ1N4007G" -> "YJ"

// 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
"1N4148" -> "1N4148"
"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.
