Variants

There is a variant of the TSSOP with a solder pad on the underside. Texas Instruments calls this the HTSSOP package. It is used for ICs which require good thermal conductivity (e.g. half-bridges).

The HTTSOP-28 component package has the following thermal resistances:

SymbolDescriptionThermal Resistance
\( R_{\theta JA} \)Junction-to-ambient thermal resistance\(31.6^{\circ}C/W\)
\( R_{\theta JC (top)} \)Junction-to-case (top) thermal resistance\(15.9 ^{\circ}C/W\)
\( R_{\theta JC (bottom)} \)Junction-to-case (bottom) thermal resistance\(1.4^{\circ}C/W\)
\( R_{\theta JB} \) Junction-to-board thermal resistance \(5.6^{\circ}C/W\)
