Vishay provides a recommended PCB layout and land pattern in their application note AN10343, which can be found on their website. It's essential to follow these guidelines to ensure proper thermal performance and to prevent thermal runaway.
The thermal resistance of the VLMA3100-GS18 depends on various factors, including the PCB material, thickness, and layout. Vishay provides a thermal resistance calculator tool on their website, which can help estimate the thermal resistance based on your specific application.
The maximum allowed voltage derating for the VLMA3100-GS18 is typically 80% of the maximum rated voltage. However, it's recommended to consult with Vishay's application engineers or refer to their application notes for specific guidance on voltage derating for your application.
The VLMA3100-GS18 is a commercial-grade component, and its use in high-reliability or aerospace applications may require additional screening and qualification. It's recommended to consult with Vishay's sales team or application engineers to discuss the feasibility of using this component in such applications.
The expected lifespan of the VLMA3100-GS18 depends on various factors, including the operating temperature, voltage, and current. Under normal operating conditions, the component can last for 10 to 20 years or more. However, it's recommended to consult with Vishay's application engineers or refer to their reliability data for more specific information.
