The recommended land pattern for the SMBJ20CA-Q can be found in the Bourns Application Note S-8151, which provides a detailed layout and footprint recommendation for optimal performance and reliability.
To ensure proper soldering, follow the recommended soldering profile and guidelines provided in the Bourns Soldering Guide, which includes temperature and time recommendations for reflow and wave soldering.
While the datasheet specifies an operating temperature range of -55°C to 150°C, it's essential to note that the device's performance and reliability may degrade above 125°C. It's recommended to derate the device's voltage and current ratings above 125°C.
While the SMBJ20CA-Q is designed for transient voltage suppression, it's not optimized for high-frequency applications. For high-frequency applications, consider using a TVS diode with a lower capacitance and inductance, such as the Bourns CDSOD323-T24C.
When selecting an SMBJ20CA-Q variant, consider the required standoff voltage, peak pulse current, and clamping voltage. The 'CA' suffix indicates a unidirectional device, while the 'A' suffix indicates a bidirectional device. Consult the Bourns TVS Diode Selection Guide for more information.
