STMicroelectronics Buttresses Presence in RF Power arena via Moisture-Resisting Devices

STMicroelectronics

India, December 17, 2013 – STMicroelectronics unveiled two new moisture-resistant radio-frequency (RF) power transistors that increases the endurance and reliability of applications operating in high-moisture environments.

The cavity of the two 50V RF DMOS devices is filled with gel, protecting the same from electro-migration such as silver dendrite migration, a well-known phenomenon that appears in standard ceramic packages due to a combination of contributing factors viz, high temperature, biasing and humidity. The use of gel-filled packages helps reduce the overall maintenance costs of the applications running in high-moisture environments.

ST’s 150W SD2931-12MR and 300W SD4933MR provides a cost-effective solution for 50V industrial RF power generators in applications such as induction heating, CO2 laser-beam sources, PECVD (Plasma-enhanced chemical vapor deposition) sputtering, and solar-cell manufacturing equipment.

The SD4933MR also features the industry’s peak breakdown voltage, which is greater than 200V combined with a 65:1 load mismatch capability in all phases, meeting the most robust design needs.

The SD2931-12MR and SD4933MR are in full production and are priced, in quantities of 1,000 units, at $53 and $77.60, respectively.
