TE Connectivity provides a recommended PCB layout and land pattern in their application note AN-1043, which can be found on their website. It's essential to follow these guidelines to ensure proper assembly and minimize thermal resistance.
The thermal pad on PBES22N10R is designed to be connected to a thermal plane on the PCB. During assembly, apply a thin layer of thermal interface material (TIM) to the thermal pad. For rework, use a thermal pad removal tool to avoid damaging the component or PCB.
While the datasheet specifies a maximum voltage rating, TE Connectivity recommends derating the voltage by 10-15% to ensure long-term reliability and to account for voltage spikes or transients in the application.
While PBES22N10R is rated for operation up to 150°C, TE Connectivity recommends limiting the junction temperature to 125°C or lower for optimal reliability and lifespan. Exceeding this temperature may reduce the component's lifespan or cause premature failure.
To ensure reliability in harsh environments, apply a conformal coating to the PCB and component. Additionally, consider using a moisture-resistant or hermetically sealed package option, if available. Consult TE Connectivity's application notes and environmental testing guidelines for more information.
