Vishay provides a recommended PCB layout and land pattern in their application note AN42171, which can be found on their website. It's essential to follow these guidelines to ensure proper thermal performance and reliability.
The TIM should be applied according to Vishay's recommendations, typically a thin layer (around 0.05 mm) of thermal interface material, such as thermal grease or thermal tape, to ensure optimal thermal performance. Improper TIM application can lead to reduced thermal performance and reliability issues.
Vishay recommends derating the voltage by 10% to 20% to ensure reliable operation and prevent premature failure. This means that if the maximum rated voltage is 1200 V, the maximum allowed voltage derating would be 1080 V to 960 V.
Follow Vishay's recommended soldering profile, which typically includes a peak temperature of 260°C to 270°C, and a soldering time of 3 to 5 seconds. Ensure the PCB is clean and free of oxidation, and use a solder with a melting point above 217°C. Avoid excessive soldering temperature, as it can cause damage to the component.
Store the components in their original packaging, away from direct sunlight, moisture, and extreme temperatures. Handle the components by the body, avoiding touching the leads or electrical contacts to prevent electrostatic discharge (ESD) damage.
