7 A Ideal Diode Shields Electronics from Reversed Supplies

The Power by Linear LTC4376, an active diode with an internal 7 A MOSFET and −40 V reverse input protection. The LTC4376 replaces power Schottky diodes in diode-OR and supply holdup circuits, which reduces voltage and power losses by 10×.

Key Features

• Low loss replacement for power Schottky diode
• 4 V to 40 V operating range
• Internal 7 A, 15 mΩ N-channel MOSFET
• −40 V reverse input protection
• Blocks dc reverse current
• Smooth oscillation-free supply switchover
• 0.6 V to 5.5 V output voltage
