The recommended footprint and land pattern for SMCJ120A can be found in the onsemi application note AND8308/D, which provides guidelines for surface mount assembly of SMC packages.
To ensure reliability in high-temperature applications, it is recommended to follow the derating guidelines provided in the datasheet, and to consider the maximum junction temperature (Tj) and storage temperature (Tstg) ratings. Additionally, onsemi provides a reliability report for the SMCJ120A, which can be requested through their website.
Yes, the SMCJ120A is lead-free and RoHS compliant, making it suitable for use in lead-free soldering processes. However, it is recommended to follow the soldering guidelines provided in the onsemi application note AND8308/D to ensure reliable assembly.
The SMCJ120A is a proprietary part number from onsemi, but equivalent parts from other manufacturers may include the 1.5KE120A from Diodes Incorporated, the SA120A from Vishay, or the P6KE120A from Littelfuse. However, it is recommended to review the datasheets and specifications of these parts to ensure they meet the requirements of your application.
To select the correct TVS diode, consider the following factors: voltage rating, peak pulse current, clamping voltage, and response time. The SMCJ120A is a 120V TVS diode with a peak pulse current rating of 3000A, making it suitable for applications requiring high surge protection. Consult the onsemi TVS diode selection guide or application notes for more information.
