| What's the smallest package available in the market today? Is there something smaller than SOT-23?

| Assy Engr 2,
We’re all familiar with the SOT-23, which is about 1.3 mm x 2.9 mm x 1 mm, and the SC-70, which is about 1.25 mm x 2 mm x 0.9 mm. But there are proprietary packages from some companies that are smaller than these. Below are some examples. Toshiba has developed its TESQ package for its transistors. The package requires 34% less space than the standard 4-pin SOT-343 surface mount package. The TESQ package measures only 1.2 mm x 1.2 mm x 0.52 mm. For IC packages requiring at least 14 or so leads, Philips came out with its Depopulated very thin Quad Flat-pack No-leads (DQFN) package, which is 2.5 mm x 3 mm. Not bad for something with 14 pins.

| There are now JEDEC-registered QFN packages. See quote from ChipScale Review below.
