The new 60-Volt (V) P-channel MOSFET delivers power conditioning and control in satellite applications, and at typical 16miliohms (mohm), offers the lowest rDS(ON) in the industry.

Intersil's FST9055 P-channel, 60V, size five, Rad Hard MOSFET has been designed to act as a switch to either control or supply power to an entire system or to a single object such as a solenoid or motor.

Delivering an rDS(ON) of 16mohm, the devices reduces heat sink requirements and improves system loses. The result is less weight, cost and size for the entire system.

"The entire Rad Hard family includes a range of voltages that results in a greater number of breakdown voltage options for the designer," said Jerry Kim product manager at Intersil.

"Many satellite bus systems designers utilize 500V devices. Intersil provides designers with the opportunity to employ a range of lower voltage FETs that dramatically reduce the rDS(ON) of the FET switch. In this case, Intersil's FST9055 represents a 60V alternative. The direct result is a reduction in system loss leading to lower system costs or higher performance and efficiency," added Kim.

The MOSFET is an enhancement-mode silicon-gate power field effect transistor of the vertical double-diffused metal-oxide semiconductor (DMOS) structure. It is the only industry MOSFET with guaranteed SEE capability with safe operating area (SOA) curves.

The device is suited for applications exposed to radiation environments, such as switching regulation, switching converters, motor drives, relay drivers and drivers for high-power bipolar switching transistors requiring high speed and low gate drive power.

Intersil's FST9055 is immediately available in a TO254 package, part number FSTJ9055 and an SMD 2 package, part number FSTYC9055. For more information, visit Intersil's Web site or contact Intersil at 1-888-INTERSIL.
