Dear Friends,

Application specific MOSFETs are a great way to achieve maximum performance for your design. They can also be used for protection purposes!

Find all my magazines from 2006 on in our free archive on bodospower.com. There is no better way to communicate. We all share one world. As a publisher I serve the world: one magazine, on time, every time.

Kind regards,

Protecting smart thermostats with compact enhanced SOA MOSFETs

In the realm of energy efficiency for residential and commercial spaces, the thermostat emerges as a pivotal player in regulating heating and cooling systems. Evolving from rudimentary manual controls, modern thermostats now boast intelligence, adapting to usage patterns and environmental conditions. This transformation not only enhances comfort but also significantly reduces energy consumption.

Smart thermostats offer an array of features like scheduling, and connectivity to optimize energy usage. While these advancements are impressive, challenges persist, particularly when it comes to connectivity for remote access, or long cable linked connections to boilers, AC units or alarm systems. To address these challenges, engineers are increasingly turning to MOSFET technology as a relay replacement, offering compactness and efficiency.
