The recommended footprint and land pattern for the SMBJ90A-TP can be found in the Micro Commercial Components' application note AN-102, which provides guidelines for PCB layout and assembly.
To select the correct TVS diode, consider factors such as the maximum voltage, current, and power rating required for your application. Also, consider the clamping voltage, response time, and capacitance of the TVS diode. The SMBJ90A-TP is suitable for applications requiring a high surge current rating and low clamping voltage.
A TVS diode is designed to protect against high-voltage transients and surges, whereas a Zener diode is used for voltage regulation and reference applications. TVS diodes have a faster response time and can handle higher surge currents than Zener diodes.
The SMBJ90A-TP is rated for operation up to 150°C, but its performance may degrade at higher temperatures. If your application requires operation above 150°C, consider using a TVS diode with a higher temperature rating or consulting with the manufacturer for guidance.
To ensure reliability and longevity, follow proper PCB design and assembly guidelines, use a suitable thermal management strategy, and avoid exceeding the recommended operating conditions. Also, consider using a TVS diode with a high surge current rating and low clamping voltage to minimize stress on the component.
