Moisture-resistant 50 V RF DMOS transistors
Thanks to the gel-filled package cavity, the 150 W
and 300 W
provide a cost-effective solution for industrial equipment operating in high-moisture environments. The gel protects the die from electro-migration such as silver dendrite migration, a well-known phenomenon in standard ceramic packages that occurs due to a combination of high temperature, biasing and humidity. The SD4933MR also features the industry’s highest breakdown voltage (> 200 V) combined with a 65:1 load mismatch capability in all phases for the most robust design needs.
