Product Description

The 1SS400SM Diode is a high-performance Fast Recovery Diode designed for surface-mount applications, offering efficient rectification in compact SMD packages. This SMD Rectifier 1SS400SM features a maximum reverse voltage of 150V and a forward current rating of 1A, ensuring reliable operation in high-frequency switching circuits. With an ultra-fast recovery time (typically 4ns) and low forward voltage drop (0.95V at 1A), it minimizes power loss and heat generation. Designed for industrial automation, power supplies, and automotive electronics, it operates within -55°C to +150°C and supports a wide voltage range up to 150V. Its miniature SMA-compliant package enables direct integration into densely populated PCBs. While optimized for fast switching and compact designs, its limited surge current tolerance requires careful circuit protection.
