The recommended footprint and land pattern for the SMBJ28A-E3/52 can be found in the Vishay Intertechnologies' application note AN10364, which provides guidelines for PCB layout and assembly.
To ensure proper soldering, follow the recommended soldering profile and guidelines provided in the Vishay Intertechnologies' application note AN10365. Additionally, use a soldering iron with a temperature range of 250°C to 260°C, and avoid applying excessive force or pressure during soldering.
The SMBJ28A-E3/52 has an operating temperature range of -55°C to 150°C, as specified in the datasheet. However, it's essential to note that the device's performance and reliability may degrade if operated at extreme temperatures for extended periods.
While the SMBJ28A-E3/52 is a high-quality TVS diode, it may not meet the specific requirements for high-reliability or aerospace applications. For such applications, it's recommended to consult with Vishay Intertechnologies' sales team or application engineers to determine the suitability of the device or identify alternative solutions.
To prevent damage or degradation, handle the SMBJ28A-E3/52 by the body, avoiding touching the leads or the glass passivated junction. Store the devices in their original packaging or in a dry, cool place, away from direct sunlight and moisture.
