The recommended footprint and land pattern for the SZ1SMB28CAT3G can be found in the Littelfuse application note AN9313, which provides guidelines for PCB layout and assembly.
To ensure reliability in high-temperature applications, it is recommended to follow the derating curves provided in the datasheet, and to consider the maximum junction temperature (Tj) of 150°C. Additionally, ensure proper thermal management and heat sinking to prevent overheating.
While the SZ1SMB28CAT3G is primarily designed for surge protection, it can be used in high-frequency applications up to 1 GHz. However, the device's performance may degrade at higher frequencies due to parasitic inductance and capacitance. Consult with Littelfuse application engineers for specific guidance.
To select the correct variant, consider the specific requirements of your application, including the maximum voltage, current, and power rating. Consult the datasheet and Littelfuse's selection guide to determine the most suitable device for your needs.
The SZ1SMB28CAT3G provides ESD protection up to ±30 kV air discharge and ±30 kV contact discharge, exceeding the requirements of IEC 61000-4-2.
