Product Description

STMicroelectronics 1N5817 is a Through Hole Schottky Rectifier rated for 20 V maximum reverse voltage and 1 A continuous forward current, packaged in the axial DO-41 form factor. It is suited for high-frequency, low voltage power conversion applications including switch mode power supplies, DC to DC converters, free wheeling diodes, polarity protection, and battery chargers.

The device features extremely fast switching speeds and very low forward voltage drops (750 mV max) which reduce conduction losses and improve overall circuit efficiency. With an operating temperature range from -65°C to 150°C, it is capable of reliable operation under demanding thermal environments. The DO-41 package measures 25.4 mm in length with a diameter of 2.71 mm, fitting compact circuit footprints easily.

Additional benefits include a peak non-repetitive forward surge current rating of 25 A for transient tolerance and compliance with UL 94 V-0 flammability standards enhancing system safety. This single diode with two axial pins is optimized for through hole mounting on printed circuit boards (PCB).

Maximum continuous forward current: 1 A. Peak repetitive reverse voltage: 20 V. Low forward voltage drop: 750 mV. Peak forward surge current: 25 A. Operating temperature range: -65°C to 150°C. Package type: DO-41 axial. Length: 25.4 mm, Diameter: 2.71 mm, Height: 5.2 mm.

UL 94 V-0 flammability rated. Applications include switch mode power supplies, DC/DC converters, polarity protection, and battery charging circuits.

This product is ideal for industrial, electronic manufacturing, and power conversion applications where efficient, robust, and reliable diode performance is required. Browse the Electronics & Electricals category at EnvMart for more Schottky Diodes and Rectifiers compliant with industry standards.
