Product details

Overview

GS2975ACNTE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across temperature and current range. It is used in USB Type-C PD bus protection where low, temperature-invariant clamping prevents damage to PD controllers.

For engineers reviewing the GS2975ACNTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability over 40A surge current, DFN-6 package thermal and layout constraints, 22V working voltage compliance, and compatibility with industrial-grade transient standards including IEC 61000-4-5 ±1kV (RS = 42Ω).

Technical Context

The GS2975ACNTE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit upon detection of overvoltage. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing R_DS(on) under surge-enabling predictable protection at 27.5–28V up to 40A.

It operates across –40°C to +125°C with <600nA reverse leakage at 22V and 175pF junction capacitance at 1MHz/22V. Its functional architecture separates input (pins 4–6) and ground (pins 1–3) terminals to minimize parasitic inductance and maximize surge current handling.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22V - defines maximum continuous DC or RMS operating voltage on protected line without triggering
Clamping Voltage	27.5–28V at 40A (8/20μs) - ensures downstream ICs see ≤28V during worst-case surge, critical for 30V-tolerant USB PD controllers
Peak Pulse Current	40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds USB IF and industrial ESD robustness requirements
Junction Capacitance	175pF at 22V/1MHz - low enough for 22V power rail protection without signal integrity impact
Dynamic Resistance	20mΩ - enables flat clamping curve; reduces voltage rise under increasing surge current
Package	DFN 1.6 × 1.6 × 0.55 mm, 6-lead - supports high-density PCB layouts with minimal board area and thermal resistance

Pinout & Package

GS2975ACNTE3 is housed in a Pb-free, RoHS-compliant DFN-6 package (1.6 mm × 1.6 mm × 0.55 mm) with exposed thermal pad not required-energy is dissipated in the FET channel, not the junction. All six terminals must be connected per layout guidelines to achieve rated 40A surge performance.

Pin/Terminal	Circuit Role	Design Meaning
Pins 1, 2, 3	GND	Common ground return path for surge current; all three must be soldered and vias-to-plane used to minimize inductance
Pins 4, 5, 6	IN	Protected line input (e.g., VBUS in USB-C); parallel connection ensures current sharing and derating-free 40A rating

Key Features

Feature	Design Value
Constant-clamp architecture	Clamping voltage varies ≤0.5V from 24A to 40A surge-eliminates design margin uncertainty vs. TVS diodes
Temperature-stable protection	Clamping remains 27.5–28V from –40°C to +125°C-enables reliable operation in uncooled industrial enclosures
Low dynamic resistance	20mΩ R_DYN ensures minimal IR drop during surge-critical for maintaining tight voltage ceilings on sensitive rails
High-energy EOS handling	1120W peak pulse power (8/20μs) supports repeated lightning-surge events without degradation
Compact DFN footprint	1.6 × 1.6 mm area saves >60% board space vs. SO-8 TVS solutions-ideal for thin client and IoT edge devices

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

uClamp2411ZA	24V working voltage, lower 24A IPP rating, higher 30V clamping, smaller 0.6×0.6mm DFN-2 package	Targeted at CC/SBU lines-not rated for 22V VBUS or 40A surges; unsuitable for primary power rail protection	Use uClamp2411ZA only for auxiliary signal-line protection; not a functional substitute for GS2975ACNTE3 in power-rail roles

Compared with TDS2211P, GS2975ACNTE3 offers identical protection performance and drop-in compatibility; versus uClamp2411ZA, it provides 67% higher surge current rating and 2V tighter clamping-making it the sole suitable option for 22V power rail EOS defense.

FAQ

What is the maximum continuous operating voltage for GS2975ACNTE3?

The GS2975ACNTE3 has a reverse stand-off voltage (V_RWM) of 22V, meaning it can continuously withstand up to 22V DC or RMS on its input terminal without conducting. This makes it suitable for 20V USB PD VBUS and other 22V-rated power rails. Exceeding this voltage risks premature conduction and reduced reliability.

Does GS2975ACNTE3 require a thermal pad or heatsink?

No, GS2975ACNTE3 does not require a thermal pad or external heatsink. Its architecture dissipates surge energy in the FET channel rather than the PN junction, and its DFN-6 package is qualified for 40A surge without additional thermal relief. Layout best practice focuses on low-inductance grounding via multiple vias-not thermal copper.

How does GS2975ACNTE3 differ from standard TVS diodes in clamping behavior?

Unlike standard TVS diodes-whose clamping voltage rises linearly with surge current (V_C = V_BR + I_PP × R_DYN)-the GS2975ACNTE3 maintains ~27.5–28V clamping from 24A to 40A due to its FET-based shunt architecture and decreasing R_DS(on). This eliminates voltage-margin uncertainty in high-surge designs.

Can GS2975ACNTE3 be used on high-speed data lines like USB SuperSpeed?

No, GS2975ACNTE3 is not intended for high-speed data lines. With 175pF junction capacitance, it would severely degrade signal integrity on USB 3.x or PCIe lanes. It is designed exclusively for power or low-frequency I/O lines (e.g., VBUS, CC, SBU, load switch inputs). For SuperSpeed lines, use sub-0.3pF devices like RClamp3371ZC.

Is GS2975ACNTE3 compliant with automotive AEC-Q200?

No, GS2975ACNTE3 is not AEC-Q200 qualified. It is specified for industrial and commercial applications with operating temperature from –40°C to +125°C, but lacks the stress testing, failure analysis, and qualification documentation required for automotive use. For AEC-Q200-compliant transient protection, consult Semtech's automotive-grade TDS variants.
