This Schottky Barrier Plastic Rectifier series—1N5817, 1N5818, and 1N5819—is engineered for high-speed switching and efficient low-voltage operation. Designed in the DO-41 (DO-204AL) package, these diodes are ideal for applications such as high-frequency inverters, DC/DC converters, and polarity protection systems. Featuring a guardring for overvoltage protection and minimal conduction losses, they ensure superior performance in demanding circuits.

Key Features:

• Guardring for enhanced overvoltage protection
• Extremely fast switching capability
• Very low forward voltage drop (as low as 0.45 V)
• Excellent high-frequency performance
• RoHS-compliant, commercial-grade construction
• Solder dip withstands up to 275 °C for 10 seconds (per JESD 22-B106)
• UL 94 V-0 rated molding compound for flammability resistance
