A J-lead package curls its leads back underneath the body, so most of the solder joint sits where you cannot see it. On a 44-pin

The HTSSOP-28 outline is standardized. Its thermal pad is not. Body size, lead pitch and lead span come from JEDEC MO-153-AET and match across vendors,

HTSSOP-38 is not one package. Two incompatible outlines ship under that name: a 9.7 mm × 4.4 mm body on 0.5 mm pitch, and a

The HTSSOP-20 package has no single thermal pad size. Texas Instruments exposes 2.96 mm × 2.96 mm at maximum material condition on PWP0020T. Renesas exposes

HTSSOP-24 is not one footprint. Texas Instruments publishes three separate 24-pin PowerPAD TSSOP drawings whose solder mask openings run from 2.44 mm × 3.42 mm

HTSSOP-16 is a 16-lead, 0.65 mm-pitch TSSOP body with an exposed thermal pad on the underside, built to Texas Instruments’ PWP0016A outline. It’s the standard

HTSSOP-14 is a 14-lead, 0.65 mm-pitch TSSOP body with an exposed thermal pad added to the underside, marketed by Texas Instruments as PWP0014A. The pad

An HTSSOP (Heat-sink/thermally-enhanced Thin Shrink Small Outline Package) is a standard TSSOP body with an exposed metal pad added to the underside for direct PCB

An HSOP package is a gull-wing small-outline body with a thick copper heat slug mechanically riveted to the leadframe and exposed on the underside. That

A gull-wing lead exits the package body, bends down, then bends out flat against the board. That second bend is the whole point: it puts
