When designing custom hardware with physical user interfaces—like push buttons, rotary encoders, or exposed sensor headers—the static electricity from a user's finger can instantly fry a delicate 3.3V microcontroller (such as an ESP32, RP2040, or STM32). While ultra-low capacitance diodes are meant for high-speed USB lines, this robust diode array features a higher capacitance (207pF), allowing it to absorb massive amounts of electrostatic energy from direct human contact without breaking a sweat.\u003c\/p\u003e\n\u003cp\u003eDesigned to protect two independent signal lines (or one differential pair) within a single, easy-to-solder SOT-23 package, it significantly reduces your component count. It is strictly optimized for 3.3V logic, ensuring the clamping voltage engages precisely when needed, long before dangerous voltage spikes can reach the processor. It is the absolute standard for securing reset pins, power buttons, UART debug ports, and slow-speed I2C buses on professional-grade DIY development boards.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003e3.3V Logic Guardian:\u003c\/b\u003e Specifically tuned for modern low-voltage microcontrollers, providing a much tighter and safer clamping threshold than generic 5V TVS diodes.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDual-Line Protection:\u003c\/b\u003e A single SOT-23 chip safeguards two separate GPIO pins against lethal electrostatic discharge (compliant with IEC 61000-4-2 standards).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eMaximum Energy Absorption:\u003c\/b\u003e The 207pF capacitance makes it incredibly robust for absorbing high-energy static shocks from mechanical switches and physical user interfaces.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eSpace-Saving SOT-23:\u003c\/b\u003e The industry-standard 3-pin surface-mount package is easy to hand-solder and requires minimal PCB real estate.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePart Number:\u003c\/b\u003e PESD3V3S2UT\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eIC Type:\u003c\/b\u003e TVS Diode Array (ESD Protection)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eWorking Voltage (Vrwm):\u003c\/b\u003e 3.3V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDiode Capacitance (Cd):\u003c\/b\u003e 207 pF (Typical)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eNumber of Channels:\u003c\/b\u003e 2 Lines\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePackage Type:\u003c\/b\u003e SOT-23 (TO-236AB, SMD\/SMT)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RC-LIFE","offers":[{"title":"Default Title","offer_id":54288016638290,"sku":null,"price":1.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1065\/8067\/2850\/files\/03e18a7a734889a8d6f95a787995e355_lFmUwl-kb1OY5YVUlA-jpg.webp?v=1786973312","url":"https:\/\/rc-life.com\/pl\/products\/pesd3v3s2ut-dual-tvs-diode-array-esd-protection-3-3v-207pf-sot-23","provider":"rc-life","version":"1.0","type":"link"}
