SMD rectifier optimized for space constrained applications

SMC Diode Solutions has announced the availability a general-purpose high voltage SMD rectifier in low-profile (DO-214AA) size format. The SD560B rectifier uniquely combines a compact footprint and 2.5mm profile with an average rectified output current (IO) rating of 5A continuous and a reverse voltage (VRRM) rating of 600V. The component additionally provides a robust forward surge rating (IFSM) of 200A, making it well suited for switching and linear power supplies. Primarily specified as an input rectifier to convert alternating line voltage to usable DC, the device is appropriate in an extensive range of uses, such as a general-purpose rectifier, freewheeling diode, or reverse polarity protection device in applications where space is limited and long life and reliability are critical. The device is employed in an array of electronic devices and equipment, including high voltage regulated power supplies, switchmode power supplies, UPSs, AC/DC adapters/chargers, DC-DC converters, lighting circuits, industrial ballasts, temperature and motor speed control circuits. This device provides a low forward voltage drop (VF) of 1.2V max. (IF = 5A) to reduce heat dissipation and maximize energy efficiency, as well as a low idle current of 9µA max. (TA = 25C, 600V) to minimize reverse energy loss. Typical junction capacitance (Cj) is 50pF @ 4V, 1MHz. Designed for automated placement efficiencies, the glass-passivated component features a rugged maximum operating junction temperature range of -65C to 175C and an MSL moisture sensitivity level of 1 per J-STD-020. It is RoHS-compliant and supplied in a UL 94V-O rated molded plastic case, made of a “Green” molding compound. Its solder plated terminals are solderable per MIL-STD-750, Method 2026. The rectifier measures 2.5mm (H) x 4.65mm (L) x 3.75mm (W), and weighs approximately 0.68 grams.
