ROHM Schottky Diodes Description
ROHM Schottky Diodes are high-performance semiconductor devices designed for low forward voltage drop and fast switching speed. These diodes are commonly employed in power supply circuits, voltage clamping, reverse current protection, and high-frequency applications due to their high efficiency and compact design. ROHM Schottky diodes are available in a range of voltage and current ratings, offering excellent thermal stability and energy-saving performance, making them ideal for use in automotive, industrial, and consumer electronics.
ROHM Schottky Diodes Applications
-DC-DC Converters - For efficient voltage regulation in power management circuits
-Switched Mode Power Supplies (SMPS) - Used as high-speed rectifiers to minimise power losses
-Reverse Polarity Protection - Prevents damage from incorrect power connections
-Freewheeling Diodes - In motor drive and inductive load circuits to suppress voltage spikes
-LED Lighting Circuits - Enhances energy efficiency and thermal performance
-Automotive Electronics - Ideal for compact and highly reliable systems under harsh conditions
