MBR30200CT Schottky Barrier Diode — 30A, 200V Rectifier
The MBR30200CT is a dual Schottky barrier diode in a common-cathode TO-220AB package, designed for applications that require low conduction loss and stable rectification performance. With a 200 V reverse voltage rating and 30 A average forward current, it supports efficient operation in switching power supplies, DC–DC converters, LED drivers, and battery-charging systems. Its forward voltage range of approximately 0.9–1.2 V at high load helps reduce thermal stress and conduction loss in high-frequency circuits.
The device incorporates high-temperature epoxy encapsulation, a guard-ring structure, and a robust terminal layout to maintain electrical and mechanical stability under industrial operating conditions. It also supports high surge current capability and consistent junction performance across a wide temperature range, making it suitable for equipment that operates in elevated-temperature or demanding environments.
With low reverse leakage, fast switching characteristics, and a thermal design optimized for heatsink mounting, the MBR30200CT provides dependable performance in rectification, free-wheeling, and output-stage applications. Designers can refer to the manufacturer datasheet for detailed electrical characteristics, thermal curves, derating guidance, and mechanical drawings.
