The recommended land pattern for the SMLJ40CA-TP is a rectangular pad with a size of 2.5mm x 1.5mm, with a 0.5mm radius corner and a 0.3mm spacing between pads.
Handle the SMLJ40CA-TP by the body, avoid touching the leads or the glass passivation, and use an anti-static wrist strap or mat to prevent electrostatic discharge (ESD) damage.
The maximum allowable voltage derating for the SMLJ40CA-TP is 10% of the rated voltage, but it's recommended to derate by 5% to ensure reliable operation.
The SMLJ40CA-TP is rated for operation up to 150°C, but it's recommended to derate the voltage and current ratings by 10% for every 10°C above 125°C to ensure reliable operation.
Store the SMLJ40CA-TP in a dry, cool place, away from direct sunlight and moisture. Use a moisture barrier bag or a desiccant to maintain a relative humidity below 60%.
