VNH3SP30-E maximum current

[APDahlen]

Hello @SouthernAtHeart,

Heat dissipation for the VNH3SP30-E is a challenge.

This diagram for the datasheet may be useful:

You may also want to use thermal via to transfer heat to the other side of the PCB. Ref

Heatsink for Surface Mount Components Using Thermal Via

Thermal PCB design is an important consideration as temperature can have a profound influence on the life of electronics. Perhaps you already know the “rule of 10” that suggests the life of a product is reduced by a factor of two for every ten-degree Celsius raise in temperature. Surface Mount technology (SMT) cooling presents a unique challenge as the devices tend to concentrate heat into smaller areas. Also, conventional heatsinks are not as readily available. In this engineering brief, we wi…

Pease share your solution as this sounds like an excellent learning opportunity.

Best wishes,
