Housed in an SMB (DO-214AA) package, the device uses glass-passivated junction technology and a clip-bonded leg structure that provides high thermal performance and low electrical resistance. The Schottky construction offers several key advantages over standard PN junction rectifiers: extremely low forward voltage drop of 500 mV at rated current, zero reverse recovery time for high-frequency operation, and low power loss for improved efficiency. The device achieves a high surge current rating of 50A (8.3 ms half-sine wave) and operates over the full -65\u00b0C to +125\u00b0C junction temperature range. The SS23 is Pb-Free, Halogen Free, and RoHS compliant.","working_principle":"The SS23 operates as a Schottky barrier rectifier using a metal-semiconductor junction (typically platinum or molybdenum on N-type silicon) rather than a conventional PN junction. In forward bias, majority carriers (electrons) cross the metal-semiconductor barrier, conducting current with a low forward voltage drop of 500 mV at 2A. Because conduction is via majority carriers only, there is no minority carrier storage \u2014 the diode switches off almost instantly with zero reverse recovery time (trr \u2248 0), making it ideal for high-frequency switching applications. In reverse bias, a small leakage current of 0.4 mA flows at 25\u00b0C (increasing to 10 mA at 100\u00b0C) due to thermionic emission over the barrier. The glass-passivated junction provides edge termination protection, ensuring stable breakdown characteristics and preventing premature failure at the junction periphery. The clip-bonded internal construction reduces parasitic resistance and improves thermal dissipation compared to traditional wire-bonded packages. The 50A surge current rating allows the device to withstand transient overcurrent events without damage.","pin_description":"\n
