The recommended land pattern for the SMLJ28CA-Q can be found in the Bourns Application Note S-8153, which provides detailed guidelines for PCB layout and assembly.
While the SMLJ28CA-Q is rated for operation up to 125°C, it's essential to consider the derating curves and thermal management to ensure reliable operation in high-temperature environments. Consult with a Bourns application engineer for specific guidance.
To prevent ESD damage, follow proper ESD handling and assembly procedures, such as using ESD-safe workstations, wrist straps, and packaging materials. Bourns also recommends using ESD-protective devices during assembly and testing.
Bourns recommends following the IPC/JEDEC J-STD-020D.1 standard for soldering profiles, with a peak temperature of 260°C and a dwell time of 30-45 seconds. However, it's essential to consult with a Bourns application engineer for specific guidance on soldering profiles.
While the SMLJ28CA-Q is designed to be robust, it's crucial to consider the mechanical stress and vibration tolerance of the device. Consult with a Bourns application engineer to determine the suitability of the device for your specific application.
