8541.29.00 - Other

This HTS classification, 8541.29.00, covers transistors that are not photosensitive and do not meet the specific criteria of the sibling category, 8541.21.00. Unlike its sibling, which is defined by a dissipation rate of less than 1 Watt, this category encompasses transistors with a dissipation rate of 1 Watt or greater. The scope includes a wide range of transistor types, such as bipolar junction transistors (BJTs), field-effect transistors (FETs), and insulated-gate bipolar transistors (IGBTs), regardless of their packaging, provided they are not specifically classified elsewhere.

The key distinguishing factor for this category is the power dissipation capability of the transistor. While 8541.21.00 is reserved for lower-power transistors, 8541.29.00 is intended for those designed to handle higher thermal loads and operate at greater power levels, commonly found in power amplification, switching, and high-power electronic circuits.

Within this category, further distinctions are made to refine classification. Subcategories exist for "Unmounted chips, dice and wafers" (8541.29.00.40), which are the raw semiconductor material before being integrated into a protective package. The remaining subcategory, "Other," captures all remaining transistors that meet the power dissipation criteria and are not unmounted, encompassing a broad array of packaged transistors used in various industrial and commercial applications.
