This document describes the features and characteristics of the FL400 to FL408 series of single-phase silicon bridge rectifiers, including voltage rating, input voltage, output current, surge overload rating, and mounting position.
The FL400‑FL408 series provides in‑line miniature single‑phase silicon bridge rectifiers suitable for printed circuit board mounting. The devices feature a plastic package with UL 94V‑0 flammability rating and lead‑solderable terminals per MIL‑STD‑202.
Key specifications include a wide reverse voltage range (50 V to 800 V), a maximum average rectified output current of 4 A, and a peak one‑cycle surge overload current of 200 A. Thermal resistance, operating temperature, and mechanical data are also provided for design reference.

The series supports a maximum recurrent peak reverse voltage ranging from 50 V to 800 V, depending on the specific model.
The devices can deliver up to 4.0 A of average rectified output current at a 50 °C ambient temperature.
They are rated for a peak one‑cycle surge overload current of 200 A.
The rectifiers operate from –55 °C up to +125 °C.
