  • Designed to switch DC current from a source to a load Low voltage , high current capability Industry-leading, ultra-low on-state resistance response to low or high voltage thresholds (optional) timers to delay on or off (optional) precision circuit breaker functionality (optional) Sleep mode for ultra-low current draw (optional) Internationally patented arrayed MOSFET technology Light weight No heat sinks or airflow required No de-rating required over full temperature range Fully encapsulated solid state design Differentiation between in-rush and shorted conditions over-current protection

Specifically designed for automotive, military, marine, aerospace, industrial, test fixtures, and various 12 and 24 volt OEM applications, POWER-GATE devices are engineered to handle shock and high-vibration environments. Our MOSFET-based relays are well suited for switching both large inductive loads and sensitive electronic equipment like power inverters, communications apparatus, or compressors. Unlike conventional mechanical relays, POWER-GATE relays have no contacts to arc, bounce, and degrade over time. Ultra-low trigger current makes POWER-GATE perfect for power sipping electrical systems where battery management is critical. Capable of switching currents between 100 amps and 300 amps, POWER-GATE may be the solid state switching solution you’ve been looking for.

Devices can be customized for opto-isolation, latching, external Vcc, external status, logic feedback, and other various features. If you need to switch from a source to a load, and mechanical relays won’t cut it, POWER-GATE may be your solution.
