While standard diodes block reverse current, this Zener diode is specifically engineered to safely conduct in reverse once the applied voltage hits its 5.6V breakdown threshold, effectively clamping the voltage and preventing it from rising further.\u003c\/p\u003e\n\u003cp\u003eAvailable at Tomson Electronics, this 5.6V Zener is capable of dissipating up to 400mW of power. This specific voltage rating is incredibly popular among hardware engineers for protecting standard 5V logic rails (like those on an Arduino). Because it clamps at 5.6V, it allows normal 5V signals to operate without interference but immediately shorts dangerous overvoltage spikes to ground. Additionally, Zener diodes in the 5V to 6V range exhibit an extremely low temperature coefficient, meaning your reference voltage will remain highly stable even as ambient temperatures fluctuate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeople also search for:\u003c\/strong\u003e 5.6v zener diode, 5v6 zener, 400mw zener diode, logic protection diode, voltage clamping diode, zener voltage regulator.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiode Type:\u003c\/strong\u003e Zener Diode\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZener Voltage (Vz):\u003c\/strong\u003e 5.6V (Typical)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Dissipation (Pd):\u003c\/strong\u003e 400 mW (0.4W)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e DO-35 (Standard Glass Axial Through-hole)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolarity:\u003c\/strong\u003e Marked with a cathode band\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range:\u003c\/strong\u003e -65°C to +200°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eDatasheet\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/1N957-1N978.pdf?v=1784968343\" target=\"_blank\" rel=\"noopener\"\u003eDownload 5.6V 400mW Zener Diode Datasheet PDF\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5V Logic Protection:\u003c\/strong\u003e Safely clamping voltage spikes on 5V communication lines or power rails to protect sensitive microcontrollers and sensors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature-Stable References:\u003c\/strong\u003e Serving as a highly accurate voltage reference point for analog-to-digital converters (ADCs) and op-amps due to its minimal temperature drift.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Regulation:\u003c\/strong\u003e Providing a stable 5.6V DC output from a higher, unregulated DC power supply when paired with a series current-limiting resistor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWaveform Clipping:\u003c\/strong\u003e Shaping analog signals and clipping AC waveforms in function generators and audio circuits.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eFrequently Asked Questions (FAQ)\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why use a 5.6V Zener to protect a 5V circuit instead of a 5V Zener?\u003c\/strong\u003e\u003cbr\u003eA: A Zener diode does not have a perfectly sharp turn-on point. If you use a 5.0V or 5.1V Zener on a 5V rail, it might start \"leaking\" small amounts of current even during normal operation, which can degrade your signals. A 5.6V Zener stays completely invisible during normal 5V operation but acts fast enough to clamp dangerous spikes before they destroy standard 5V logic chips.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I wire this Zener diode in my circuit?\u003c\/strong\u003e\u003cbr\u003eA: To use it as a voltage regulator or clamp, you must install it in \u003cstrong\u003ereverse bias\u003c\/strong\u003e. Connect the cathode (the side with the black band) to the positive voltage line, and the anode to ground. If installed forwards, it will act like a standard diode and drop only about 0.7V.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Do I need a resistor to use this diode?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Once the diode hits its 5.6V breakdown, its internal resistance drops drastically. You must place a series resistor between your power source and the Zener to limit the current, otherwise the diode will draw too much power, exceed its 400mW limit, and burn out.\u003c\/p\u003e\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × 5.6V 400mW Zener Diode (DO-35)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORTED","offers":[{"title":"Default Title","offer_id":48385581514990,"sku":"DIO-00755","price":0.94,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/ZenerDIODEall.jpg?v=1784966998","url":"https:\/\/www.tomsonelectronics.com\/products\/5-6v-400mw-zener-diode","provider":"Tomson Electronics ","version":"1.0","type":"link"}
