Part of the robust P6KE series, this component can safely absorb up to 600 Watts of peak pulse power, clamping dangerous voltage spikes in picoseconds before they reach your delicate microcontrollers or communication ICs.\u003c\/p\u003e\n\u003cp\u003eAvailable at Tomson Electronics, the \"CA\" suffix designates this as a \u003cstrong\u003ebi-directional\u003c\/strong\u003e diode. This means it protects against voltage surges in both positive and negative directions, making it ideal for protecting AC lines, analog signals, and data buses where voltage swings below ground. With a reverse stand-off voltage of 5.8V and a breakdown voltage of 6.8V, it is the perfect heavy-duty protector for standard 5V logic power rails and high-speed data lines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeople also search for:\u003c\/strong\u003e p6ke 6.8 ca diode, 6.8v tvs diode, bi-directional tvs, 600w transient voltage suppressor, p6ke series, surge protection diode.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e P6KE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiode Type:\u003c\/strong\u003e Transient Voltage Suppressor (TVS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirectionality:\u003c\/strong\u003e Bi-Directional (CA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeak Pulse Power (Pppm):\u003c\/strong\u003e 600W (10\/1000 µs waveform)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReverse Stand-Off Voltage (Vrwm):\u003c\/strong\u003e 5.8V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBreakdown Voltage (Vbr):\u003c\/strong\u003e 6.8V (Typical)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Clamping Voltage (Vc):\u003c\/strong\u003e 10.5V at Peak Pulse Current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e DO-15 (Axial Through-hole)\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\/p6ke.pdf?v=1784971438\" target=\"_blank\" rel=\"noopener\"\u003eDownload P6KE6.8CA TVS Diode Datasheet PDF\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5V Rail Protection:\u003c\/strong\u003e Placed across standard 5V power supplies to absorb destructive surges from inductive load switching (like motors or relays).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eData Line Protection:\u003c\/strong\u003e Safeguarding RS-232, RS-485, and CAN bus communication lines from electrostatic discharge (ESD) and electrical fast transients (EFT).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Signal Protection:\u003c\/strong\u003e Protecting analog audio or low-voltage AC sensor lines, as the bi-directional nature allows normal AC waveforms to pass without clipping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eI\/O Port Defense:\u003c\/strong\u003e Adding an essential layer of hardware security to exposed microcontroller pins that interface with the outside world.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eFrequently Asked Questions (FAQ)\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between a TVS diode and a Zener diode?\u003c\/strong\u003e\u003cbr\u003eA: While both clamp voltage, they are built for entirely different purposes. A Zener diode is designed to regulate a continuous, steady voltage at low power. A TVS diode is designed with a much larger P-N junction to absorb massive, instantaneous surges of power (like 600W) for a tiny fraction of a second to prevent circuit destruction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does the \"CA\" mean, and how does it differ from the \"A\" version?\u003c\/strong\u003e\u003cbr\u003eA: The \"CA\" suffix (e.g., P6KE6.8CA) means the diode is Bi-Directional. It has no polarity and protects against spikes in both directions. The \"A\" suffix (e.g., P6KE6.8A) means it is Uni-Directional; it protects against positive spikes but acts like a regular short-circuit diode to negative voltages. A bi-directional TVS does not have a cathode band printed on the body.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I wire this TVS diode in my circuit?\u003c\/strong\u003e\u003cbr\u003eA: TVS diodes are wired in \u003cstrong\u003eparallel\u003c\/strong\u003e with the component or power rail you want to protect. You connect it directly across the power and ground lines (or signal and ground lines). Because this specific model is bi-directional, it does not matter which lead goes to power and which goes to ground.\u003c\/p\u003e\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × P6KE6.8CA 6.8V 600W Bi-Directional TVS Diode\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOMSON ELECTRONICS","offers":[{"title":"Default Title","offer_id":48385623720174,"sku":"DIO-00879","price":4.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/P6KE6.8CADIODE.jpg?v=1784973181","url":"https:\/\/www.tomsonelectronics.com\/products\/6-8v-600w-bi-directional-tvs-diode-p6ke-6-8ca","provider":"Tomson Electronics ","version":"1.0","type":"link"}
