RB218BM200FH
Super Low IR, 200V, 20A, TO-252 (DPAK), Schottky Barrier Diode for Automotive

RB218BM200FH is the 200V ultra-low IR SBD optimized for automotive applications including powertrains and xEVs. It offers ultra-low leakage current (IR) characteristics to achieve high withstand voltage of 200V. Replacing FRDs and rectifier diodes typically used in vehicle systems with ROHM's new SBDs make it possible to improve forward voltage (VF) characteristics significantly (11% lower than conventional FRDs). This reduces application power losses and allows smaller package designs by reducing heat generation, contributing to greater space savings.

About the RBxx8 series: SBDs featuring superior efficiency are expected to replace conventional rectifier diodes and FRDs in automotive power supply exposed to high temperature. However, one drawback of SBDs is degraded IR characteristics at higher operating temperatures that can lead to thermal runaway, requiring products that provide stable operation at higher temperatures. The RBxx8 series utilizes a barrier metal optimized for high temperature that significantly improves the IR characteristics (which is perhaps the most important challenge when using SBDs in automotive power supply). This ensures safe operation at high temperatures in automotive and industrial applications, eliminating the possibility of thermal runaway.
