Introduction to the SiC Chip in TO-220AB Package

Performance Advantages:

For example, SiC Schottky barrier diodes (SBDs)—compared with conventional silicon fast-recovery diodes (FRDs)—do not exhibit reverse recovery current, thereby significantly reducing switching losses, and can withstand voltages of 600 V or higher.

What is the difference in the TO-220AB package for SiC chips?

TO‑220AB refers to a silicon carbide chip packaged in the TO‑220AB form factor. The TO‑220AB is a standard through-hole package widely used in power electronics, commonly employed for silicon carbide power devices such as SiC MOSFETs, and well-suited to meet the mounting and thermal management requirements of medium- to high-power applications.

Structure and Installation

This package typically features a 3‑pin configuration, housed in a plastic enclosure, and is designed for through-hole mounting. Its key advantage is an insulating base that allows direct attachment to a heat sink, eliminating the need for additional insulating shims. This not only streamlines the assembly process but also minimizes thermal losses, thereby enhancing thermal management efficiency. The typical dimensions are approximately 8.24 × 10.5 × 4.7 mm, and the package offers high mechanical robustness, making it suitable for a wide range of operating environments.

Heat Dissipation and Load-Bearing Capacity

It delivers outstanding thermal performance, with a typical junction-to-case thermal resistance of approximately 3 °C/W, efficiently dissipating the heat generated during operation of silicon carbide chips and accommodating the high power density of SiC devices. Additionally, it can handle substantial current levels: for instance, certain SiC devices employing this package achieve a continuous drain current of up to 29 A and a pulsed current of up to 72 A, meeting the current requirements of medium- to high-power applications.
