## Description

The Multicomp Pro DF04S is a single-phase surface-mount bridge rectifier housed in a compact 4-pin SMD case style, designed for efficient AC-to-DC full-wave rectification on printed circuit boards. Built on a reliable, low-cost glass-passivated molded plastic construction featuring a UL 94V-0 flammability rating, this component delivers a maximum average forward rectified current of 1 A and handles a repetitive peak reverse voltage (VRRM) up to 400 V, with an RMS voltage rating of 280 V and a maximum DC blocking voltage of 400 V. 

Electrically optimized for low power losses, the DF04S exhibits a maximum forward voltage drop of 1.1 V per element at 1 A DC and supports a high peak forward surge current (IFSM) rating of 30 A for an 8.3 ms single half-sine wave superimposed on a rated load, alongside an $I^2t$ fusing rating of 3.735 $A^2s$. Operating across a wide junction temperature range of -55°C to +150°C and offering a typical thermal resistance (RθJA) of 40°C/W when mounted on a PCB with 0.5 x 0.5-inch (13 x 13 mm) copper pads, it maintains stable reverse characteristics with a maximum DC reverse current of 10 µA at 25°C.

This 400 V bridge rectifier diode is well-suited for integration into compact power conversion topologies, AC/DC power supplies, consumer electronics, and industrial control circuits requiring reliable single-phase rectification. Its surface-mount footprint optimizes board space while accommodating resistive, inductive, and capacitive loads—requiring only a standard 20% current derating when operating under capacitive load conditions.
