The recommended footprint and land pattern for the 1.5SMBJ48CA can be found in the Bourns Application Note AN164, which provides guidelines for surface mount assembly and layout considerations.
To prevent damage, handle the 1.5SMBJ48CA by the body only, avoiding touching the leads or the glass passivation. Use anti-static wrist straps, mats, or packaging to prevent electrostatic discharge (ESD) damage.
The maximum allowable soldering temperature for the 1.5SMBJ48CA is 260°C (500°F) for 10 seconds. Exceeding this temperature or time may damage the device.
While the 1.5SMBJ48CA is a high-quality device, it may not meet the specific requirements of high-reliability or aerospace applications. Bourns offers other products that are specifically designed and qualified for these applications, such as the SRP050-4R7M or the SMF050-4R7M.
The 1.5SMBJ48CA has a polarity marker on the package, which indicates the cathode (K) end. The cathode should be oriented according to the PCB layout and the specific application requirements.
