The recommended footprint and land pattern for SMAJ28CA-Q can be found in the Bourns application note AN-19, which provides guidelines for surface mount assembly and layout considerations.
To ensure reliability in high-temperature applications, it is recommended to follow the derating curves provided in the datasheet, and to consider the thermal resistance and power dissipation of the device. Additionally, proper PCB design, thermal management, and cooling mechanisms should be implemented.
While the SMAJ28CA-Q is primarily designed for transient voltage suppression, 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. It is recommended to consult with Bourns' application engineers for specific guidance.
To select the correct SMAJ28CA-Q variant, consider the following factors: working voltage, peak pulse current, and clamping voltage. Refer to the datasheet and consult with Bourns' application engineers if necessary. They can help determine the most suitable variant for your specific application.
The SMAJ28CA-Q is RoHS and REACH compliant, and meets the requirements of various environmental regulations. However, it is recommended to consult with Bourns' documentation and regulatory experts to ensure compliance with specific regional and industry regulations.
