Vishay provides a recommended PCB layout and land pattern in their application note AN1025, which can be found on their website. It's essential to follow these guidelines to ensure proper thermal management and minimize thermal resistance.
The datasheet recommends using a thermal interface material (TIM) with a thermal conductivity of at least 1 W/m-K. Apply a thin, even layer of TIM to the base plate of the device, and ensure it's free of voids and air pockets. Vishay also recommends using their own TIM, part number MAL-TIM-1.
While the datasheet specifies the maximum voltage rating, it's essential to derate the voltage based on the operating temperature. As a general rule, derate the voltage by 1% per degree Celsius above 25°C. Consult Vishay's application notes or contact their technical support for specific guidance.
Follow the recommended soldering profile and guidelines provided in the datasheet. Use a solder with a high melting point (e.g., SAC305) and ensure the PCB is designed with a sufficient solder mask to prevent solder bridging. Inspect the solder joints for voids and ensure they meet the acceptance criteria outlined in IPC-A-610.
Vishay provides reliability data and lifespan expectations in their application notes and technical documentation. The MDP160110K0GE04 is designed to meet or exceed industry standards for reliability, with a typical lifespan of 10-15 years or more, depending on operating conditions and environmental factors.
