soft recovery diode SPTECH SPT50U65SK2 with high repetitive peak reverse voltage and low IR value
Product Overview
The SPT50U65SK2 is an ultrafast soft recovery diode optimized for high-frequency power conditioning systems, offering reduced losses and improved EMI/RFI performance. Its soft recovery characteristic provides buffering in most applications, making it suitable for power converters and other scenarios where switching losses are not a primary concern. Key advantages include ultrafast recovery, a high operating junction temperature of 175, high-frequency operation, low IR value, and very low forward voltage, all achieved with an epitaxial chip construction.
