FBS-GAM01-P-R100

Power Distribution Switches, Load Drivers Overview

The FBS-GAM01-P-R100 is a radiation-hardened, single low-side power driver module designed for space applications. It integrates an N-Channel GaN HEMT and a Schottky rectifier within a 9-SMD package. The device features a fully de-rated 100 V/10 A rating, with internal components rated at 200 V. It operates with a supply voltage of 4.5V to 5.5V and supports load voltages up to 200V. The output current capability ranges from 0.0065 A to 0.09 A in specific gate driver configurations, while the power stage handles up to 12A. Operating temperature spans -40°C to 85°C.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix (R100) against official EPC Space documentation to confirm the exact voltage and current ratings. Ensure compatibility with space-grade environmental requirements. Confirm moisture sensitivity level and mounting specifications prior to integration. Request updated datasheets directly from the manufacturer to validate current production status and technical parameters.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for applications requiring radiation tolerance and high-voltage isolation in a compact form factor. The integrated GaN HEMT offers high-speed switching capabilities. Consider the 9-SMD module size for PCB layout constraints. Verify that the 4.5V to 5.5V supply range aligns with the system logic levels. Evaluate the de-rating benefits for long-term mission reliability.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the FBS series of radiation-hardened power modules from EPC Space. These modules combine power switching and driving functions into a single unit. The series includes variants with different voltage ratings, such as 50V and 100V options. The R100 variant specifically targets 100V applications with robust de-rating margins for critical space missions.

Power Distribution Switches, Load Drivers Replacement Considerations

Direct substitutes are not publicly confirmed. Similar radiation-hardened GaN drivers may exist but require rigorous qualification matching. Consult EPC Space for approved cross-reference parts. Generic commercial GaN drivers lack the necessary radiation hardness for space use.
