SOT-883 (Small-outline Transistor 883) is a 3-lead SMD component package that is very similar to a DFN package. It is also very similar to the SOD-882 component package (note: that’s SOD, not SOT!). It has the same outside dimensions as the SOD-882, except with the addition of an extra pad. This presumably explains the transition from SOD to SOT — the two pin package is used for diodes, whilst this three pin package is used for transistors.

Synonyms:

  • CASE 506DB (onsemi1)
  • DFN1006-3 (NXP2)
  • SC-101 (JEITA, EIAJ)3
  • XDFN3 (onsemi)

Package Dimensions:

  • Length: 1.0mm (nom)2
  • Width: 0.6mm (nom)2
  • Height: 0.50mm (nom)2

Pitch:

  • 0.35mm between the centers of the two small pads (called the nominal pitch by Nexperia)2
  • 0.65mm between the centers of the small pads and the large pad (called the minimal pitch by Nexperia)2

Solderability: Almost impossible to solder with a hand-held soldering iron due to the pads being on the bottom of the package. Need to use reflow oven/hot air soldering techniques.

Typical PCB Land Area: 1.17mm21.17mm^2 (1.30x0.90mm)2

Common Uses:

  • MOSFETs

Similar To:

  • DFN
  • SOD-882 (2 pins instead of 3, in the same sized package)

onsemi (formally On Semiconductor) calls this package the XDFN31. However, you have to be careful as onsemi also uses the name XDFN3 for slightly different packages, for example, the NTNS5K0P021Z MOSFET, which has a smaller package size of 0.62x0.42x0.4mm4, rather than 1.0x0.6x0.5mm of the SOT-883. The key difference is the “case code” which is CASE 506CB11 for the SOT-883, but CASE 711BH4 for the smaller 0.62x0.42x0.4mm package.
