ESD Protection Diode, 0402, 9V, 162mW

This single-channel ESD Protection Diode from Texas Instruments features a 10pF capacitance and a 9V breakdown voltage, providing robust circuit protection. It offers ±20kV IEC 61000-4-2 (level 4) contact and air-gap ESD protection, ensuring reliable defence against electrostatic discharge events. The back-to-back TVS diode configuration allows for bipolar or bidirectional signal support, making it highly versatile for various circuit designs.

With a 10pF line capacitance, this diode is suitable for a wide range of applications supporting data rates up to 500Mbps. It provides system-level ESD protection for low voltage I/O interfaces up to ±9V, alongside IEC 61000-4-5 surge protection of 4.5A (8/20µs). It boasts a maximum ultralow leakage current of 100nA and operates within a temperature range of -40°C to 125°C.

Typical applications include circuit protection for audio lines (such as microphones, earphones, and speakerphones), SD interfacing, keypads or other buttons, VBUS and ID pins of USB ports, and general-purpose I/O ports. It is ideally suited for safeguarding end equipment like eBooks, tablets, remote controllers, wearables, set-top boxes, and electronic point of sale equipment. The compact 0402 case style ensures it fits seamlessly into dense circuit board layouts, with product dimensions of 43 mm x 33 mm x 15 mm and a lightweight profile of just 0.454 grams.
