ESD122DMXR is a two‑channel bidirectional transient‑voltage‑suppression (TVS) ESD protection array manufactured by Texas Instruments, optimized to safeguard high‑speed differential data lines from destructive electrostatic discharges and fast electrical transients. Packaged in an ultra‑compact 3‑pin X2SON surface‑mount housing measuring only 1.0 mm × 0.6 mm, this protection device delivers ±17 kV contact and air‑gap ESD compliance with IEC 61000‑4‑2 Level 4 standards, maintains ultra‑low 0.2 pF typical I/O‑to‑ground capacitance to preserve signal integrity for interfaces above 10 Gbps, and supports reliable long‑term operation over the wide industrial temperature range from ‑40 °C to 125 °C for portable, consumer and industrial high‑speed communication hardware.
Key Features & Applications
● Dual‑channel bidirectional ESD protection with ±17 kV contact discharge and ±17 kV air‑gap discharge rating under IEC 61000‑4‑2 Level 4 specification.
● Ultra‑low typical capacitance of 0.2 pF from I/O to ground and 0.1 pF between channels, eliminating signal distortion for data rates up to and exceeding 10 Gbps.
● Maximum leakage current limited to 10 nA, minimizing idle‑mode power consumption on sensitive high‑speed signal traces.
● Extra transient protection for electrical fast transients of 80 A (5/50 ns) and surge events of 2.5 A (8/20 µs).
ESD122DMXR is widely deployed to protect high‑speed differential signal lines inside USB Type‑C connectors, USB 3.1 Gen 2 communication ports, HDMI 2.0 video interfaces, SATA storage links, PCI‑E signal traces, MHL connections, wearable gadgets, smartphone peripheral circuits, industrial data‑transfer modules and high‑speed test equipment, wherever high‑bandwidth differential signals require ESD shielding without signal‑speed‑related performance loss.
FAQ
Q: Why is ultra‑low capacitance critical for this ESD chip?
A: High capacitance will degrade high‑speed differential signals, while its 0.2 pF rating preserves signal integrity for 10 Gbps and faster interfaces.
Q: Can it protect single‑ended signal lines?
A: Yes, though it is primarily optimized for differential pair protection.
Alternative ESD protection diode Models
● ESD122DMYR: Function‑identical dual‑channel high‑speed TVS diode in the larger 1.3 mm × 0.6 mm X2SON‑3 package, providing extra soldering pad area for improved assembly yield.
● TPD4E02B04: Four‑channel ultra‑low‑capacitance ESD protector from Texas Instruments, suitable for projects requiring ESD coverage for multiple differential pairs with one single component.
● SRV05‑2: Bidirectional 2‑channel ESD protection diode with slightly higher capacitance, a cost‑effective substitute for interfaces operating below 5 Gbps when budget constraints apply.
