Product details

Overview

GS2974ACNTE3Z 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 maintains a stable 27.5–28V clamping voltage across its full current and temperature range (−40°C to +125°C). It is deployed in USB Type-C PD bus protection where precise clamping below controller damage thresholds is critical.

For engineers reviewing the GS2974ACNTE3Z datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge current and temperature, low dynamic resistance (20 mΩ), junction capacitance (175 pF at 22V), and DFN 1.6×1.6mm 6-lead layout compatibility with high-density USB PD and industrial load switch interfaces.

Technical Context

The GS2974ACNTE3Z uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-from 24A to 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω)-due to decreasing R_DS(on) under increasing current.

It operates over −40°C to +125°C with reverse stand-off voltage (V_RWM) of 22V, breakdown voltage (V_BR) of 25–27.9V (I_t = 1mA), and reverse leakage <600 nA at V_RWM. Its 175 pF junction capacitance at 22V/1MHz and 20 mΩ dynamic resistance support robust signal integrity and low-voltage overshoot in high-speed power rail protection.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22V - defines maximum continuous DC bus voltage it can protect without leakage or conduction.
Clamping Voltage	27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during surge.
Peak Pulse Current	40A (tp = 8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements.
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds standard USB interface ESD immunity requirements.
Dynamic Resistance	20 mΩ (measured 1–40A, tp = 8/20μs) - enables flat clamping response and minimizes voltage rise under high-current transients.
Junction Capacitance	175 pF at VR = 22V, f = 1MHz - low enough for 22V power rail protection without degrading transient response or causing signal distortion.
Operating Temperature	−40°C to +125°C - supports deployment in industrial equipment, automotive-adjacent IoT, and thermally constrained notebooks.

Pinout & Package

GS2974ACNTE3Z is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads and UL 94V-0 molding compound. All pins must be connected per functional grouping to achieve rated 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 used to internal ground plane to minimize inductance.
Pins 4, 5, 6	IN	Protected line input (e.g., VBUS in USB-C); parallel connection of all three pins lowers impedance and maximizes 40A handling capability.

Key Features

Feature	Design Value
FET-based transient diversion	Replaces conventional TVS with active shunt architecture, enabling near-constant clamping voltage independent of surge amplitude or temperature.
Stable clamping over temperature	Clamping voltage remains 27.5–28V from −40°C to +125°C - eliminates derating concerns in thermally demanding industrial or automotive-embedded applications.
Low dynamic resistance	20 mΩ ensures minimal IR drop during 40A surges, directly contributing to predictable, low-voltage clamping behavior.
High EFT immunity	±4kV per IEC 61000-4-4 (5/50ns, 100kHz & 5kHz bursts) - protects against repetitive fast transients common in motor drives and switching power supplies.
Space-optimized DFN	1.6×1.6mm footprint saves >50% board area vs. legacy SO-8 or SOT-23 TVS solutions while maintaining 1120W peak pulse power rating.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TDS2211P	Same device; GS2974ACNTE3Z is Semtech's alternate ordering code for TDS2211P - identical electrical specs, package, and marking (T22 + date code).	No functional difference; both qualify for USB PD, industrial load switch, and IoT applications requiring 22V working voltage and 40A surge rating.	Select GS2974ACNTE3Z for distribution through authorized channels using Semtech's standard tape-and-reel packaging (3,000 pcs/reel, 7″).
uClamp2411ZA	24V working voltage, lower 24A IPP rating, higher 30V clamping, and 120 pF capacitance - optimized for CC/SBU lines, not main VBUS.	Intended for low-voltage, low-capacitance data-line protection (e.g., USB-C CC pins), not 22V power rail protection.	Not interchangeable with GS2974ACNTE3Z; use only for auxiliary signal lines where <0.5V clamping margin and sub-150pF are required.

Compared with TDS2211P (identical part), GS2974ACNTE3Z offers identical surge performance and layout compatibility; compared with uClamp2411ZA, it provides 67% higher peak current rating and 2V lower clamping at 40A-making it suitable for primary VBUS protection where uClamp2411ZA would fail catastrophically.

FAQ

What is the exact package type and dimensions of GS2974ACNTE3Z?

GS2974ACNTE3Z uses a DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads. Pins 1–3 are GND; pins 4–6 are IN. The package is Pb-free, halogen-free, RoHS/WEEE compliant, and carries UL 94V-0 flammability rating. Land pattern and outline drawings are provided in Semtech's official datasheet Rev 2.5.

Does GS2974ACNTE3Z meet IEC 61000-4-5 surge immunity standards?

Yes, GS2974ACNTE3Z is rated for 40A peak pulse current (tp = 8/20μs) and ±1kV (1.2/50μs, RS = 42Ω) per IEC 61000-4-5, making it suitable for Level 4 industrial surge immunity. Its clamping voltage remains tightly controlled at 27.5–28V under these conditions, ensuring downstream ICs stay within safe operating voltage limits.

How does GS2974ACNTE3Z differ from standard TVS diodes in clamping behavior?

Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS2974ACNTE3Z uses a triggered FET architecture that maintains ~27.5–28V clamping from 24A to 40A and across −40°C to +125°C. This eliminates thermal derating and ensures consistent protection margins in real-world operating conditions.

Can GS2974ACNTE3Z be used for USB-C CC line protection?

No-GS2974ACNTE3Z is designed for 22V power rail (VBUS) protection, not low-voltage CC/SBU signaling. For CC lines, Semtech recommends uClamp2411ZA (24V, 120 pF, 24A), which provides lower capacitance and appropriate voltage margin. Using GS2974ACNTE3Z on CC lines would risk excessive capacitance and incorrect clamping thresholds.

What is the maximum junction temperature and storage temperature range for GS2974ACNTE3Z?

GS2974ACNTE3Z has a junction and storage temperature range of −55°C to +150°C, with an operating temperature range of −40°C to +125°C. These ratings are validated per Absolute Maximum Ratings in the official datasheet and support deployment in extended-temperature industrial and automotive-adjacent applications.
