300 V MOSFET replacement for electro-mechanical relays

29 January 2003 Power Electronics / Power Management Products & Solutions

International Rectifier's IRF3000 is a 300 V, N-channel HEXFET power MOSFET developed to replace electro-mechanical relays in many telecom and networking applications. Because it is solid-state and has no mechanical parts, it increases overall system reliability, and is up to 30% smaller than an electro-mechanical relay.

The IRF3000 is more efficient than an electro-mechanical relay, with more than 90% reduction in on-state resistance compared to mechanical relays, minimising conduction losses. Ultra-low gate charge minimises switching loss. The IRF3000 is easier to drive than a relay, simplifying circuits and reducing overall system cost. Since typical networking and telecom systems use thousands of relays, minimising switching loss, conduction loss and cost of individual devices is critical.

According to IR, electromechanical relays have a life expectancy of 100 000 to 10 million operations, and under similar load conditions, the IRF3000 could expect a life expectancy approaching a billion switching cycles.

The IRF3000 is designed for switching applications requiring a low current switch (1,6 A) with up to 200 V input that do not require isolation, or when the load voltage does not reverse in polarity. It is also suitable for use in high frequency DC-DC converters. The device is rated at 300 V breakdown voltage providing the required safety margin for up to 200 V input switching applications.
