TO-PMOD-7 Component Package

A 3D render of the TO-PMOD-7 component package.

Transistor Outline Power Module 7 is a rather large SMD package with good heat sinking abilities. Texas Instruments uses this package for some of their DC/DC power modules, which have built in shielded inductors.

Pitch is 1.27mm (between the six pins, excluding the pad).

Height: 4.57mm.

Land Area: $10.16x13.77mm = 140mm^2$

Thermal Resistances

• $T_{JC} = 1.9^{\circ}{\rm C}/W$
• $T_{JA} = 16^{\circ}{\rm C}/W$ (with the recommended land pattern)
