The RS2ABF-RS5ABF SMBF surface-mount fast-recovery diodes, packaged in an SMBF package, are designed for ultra-high power density applications. The full series covers reverse voltage ratings from 50V to 1000V, delivering average rectified currents of 2A, 3A, and 5A, respectively, at a case temperature of 125°C, with peak surge currents of 50A, 80A, and 150A. Glass-passivated chip junction technology ensures reliability under extreme operating conditions, with a maximum forward voltage drop of 1.3V and reverse leakage current limited to 5μA to 10μA at the rated voltage of 25°C. The devices are compliant with EU RoHS Directive 2011/65/EU, and feature a 1.3mm package height and 57mg weight for enhanced thermal management.
The thermal resistance ranges from 60°C/W to 40°C/W, based on a 5×5cm copper pad. The operating temperature range spans -55°C to +150°C, making them suitable for heavy resistive or inductive loads. Capacitive loads require a 20% current derating. Key advantages include fast recovery speeds of 150ns to 500ns and junction capacitance of 28pF to 45pF. Certified to MIL-STD-750 Method 2026 welding, this device provides ultra-high load capacity solutions for industrial power systems, electric vehicle charging modules, and high-power inverters.
