The \u003cstrong\u003e1N5822 Schottky Diode\u003c\/strong\u003e solves this by offering an exceptionally low forward voltage drop and ultra-fast switching speeds, making it an essential component for modern power electronics.\u003c\/p\u003e\n\n\u003cp\u003eAvailable at Tomson Electronics, this 3-Amp, 40-Volt Schottky barrier rectifier is widely used in high-frequency switch-mode power supplies (SMPS) and DC-DC converters. Because it dissipates very little heat, it is also the perfect choice for reverse polarity protection on custom embedded devices—such as battery-powered LoRa nodes or flight controllers—and acts as an excellent freewheeling diode to protect circuits from voltage spikes generated by inductive loads like robotics motors.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eNote: The industry standard part number is 1N5822, though it is frequently typed as IN5822.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAlso searched as:\u003c\/strong\u003e IN5822 diode, 3A schottky barrier diode, 1N5822 rectifier, low voltage drop diode, DO-201AD diode, 3 amp fast switching diode.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 1N5822 (Often searched as IN5822)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiode Type:\u003c\/strong\u003e Schottky Barrier Rectifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Forward Current (If):\u003c\/strong\u003e 3.0A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeak Reverse Voltage (Vrrm):\u003c\/strong\u003e 40V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForward Voltage Drop (Vf):\u003c\/strong\u003e ~0.525V at 3A (significantly lower at lower currents)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e DO-201AD (Axial Lead \/ Through-Hole)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -65°C to +125°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eCommon Applications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supplies:\u003c\/strong\u003e Highly efficient rectification in high-frequency switch-mode power supplies (SMPS) and DC-DC step-down converters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReverse Polarity Protection:\u003c\/strong\u003e Protecting sensitive microcontrollers and custom PCBs from being damaged if a battery is plugged in backward, with minimal voltage loss.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Protection (Snubber):\u003c\/strong\u003e Acting as a flyback\/freewheeling diode across DC motors in mechanical soccerbots or drones to safely dissipate inductive voltage spikes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolar Panels:\u003c\/strong\u003e Used as blocking diodes in small solar charging setups to prevent batteries from discharging back into the solar panel at night.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eFrequently Asked Questions\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between a 1N5822 Schottky diode and a standard 1N4007 diode?\u003c\/strong\u003e\u003cbr\u003e\nA: A standard 1N4007 silicon diode has a forward voltage drop of around 0.7V to 1.0V and switches relatively slowly, making it better for low-frequency AC mains rectification. The 1N5822 Schottky diode has a much lower voltage drop (around 0.3V to 0.5V) and switches incredibly fast, making it ideal for high-frequency DC applications and saving battery power.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How do I know which way to install this diode?\u003c\/strong\u003e\u003cbr\u003e\nA: Like most through-hole diodes, the 1N5822 has a silver band printed on one end of the black cylindrical body. This silver band indicates the Cathode (Negative) side. Current flows from the unbanded end (Anode) toward the banded end.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this in a 12V or 24V circuit?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes. The 1N5822 is rated to safely block up to 40 Volts in reverse, so it will work perfectly in 5V, 12V, or 24V logic and power systems, provided the continuous current does not exceed 3 Amps.\u003c\/p\u003e\n\n\u003ch5\u003eResources\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca title=\"1N5822 Schottky Diode Datasheet\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/1N5820.PDF?v=1787914836\" target=\"_blank\"\u003e1N5820 - 1N5822 Series Datasheet (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × 1N5822 Schottky Diode (3A 40V)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3NIX","offers":[{"title":"Default Title","offer_id":49510229016814,"sku":"DIO-00836","price":26.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/IN_5822_3NIX_DIODE.avif?v=1787915884","url":"https:\/\/www.tomsonelectronics.com\/products\/1n5822-schottky-diode-3a-40v","provider":"Tomson Electronics ","version":"1.0","type":"link"}
