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 management and minimize thermal resistance.
The VS-15ETH03SHM3 comes with a pre-applied TIM. However, if you need to rework or replace the TIM, Vishay recommends using a thermal interface material with a thermal conductivity of at least 1 W/m-K. Follow the manufacturer's instructions for application and curing.
Vishay recommends derating the maximum voltage by 10% to ensure reliable operation. For example, if the maximum voltage rating is 15 V, the derated voltage would be 13.5 V.
While the VS-15ETH03SHM3 is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz. However, you should carefully evaluate the device's performance and consider the effects of parasitic inductance and capacitance.
To ensure reliability, follow Vishay's recommended operating temperature range and derate the device's power rating accordingly. Also, consider using a heat sink or thermal management system to keep the junction temperature below 150°C.
