Product details
Overview
GS2974ACNE3 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. Used in USB Type-C PD bus protection to prevent damage to controllers during lightning surges or connector hot-plug events.
For engineers reviewing the GS2974ACNE3 datasheet, pinout, applications, or equivalent options, this page provides verified package mapping, functional pin roles, real-world clamping behavior under 40A transients, thermal stability data up to +125°C, and validated alternatives for industrial and portable power interface designs.
Technical Context
The GS2974ACNE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage beyond ~27V breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V at both 24A and 40A-due to decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C with <20mΩ dynamic resistance (8/20μs), 175pF junction capacitance at 22V/1MHz, and <600nA reverse leakage. Its DFN 1.6×1.6×0.55mm package integrates three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3) to minimize parasitic inductance and maximize surge current sharing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - Matches nominal USB PD bus voltage; ensures no leakage or conduction during normal operation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - Remains stable across full rated current and temperature, protecting downstream ICs with tight VMAX margins. |
| Peak Pulse Current | 40A (8/20μs) - Meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD interfaces. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - Survives repeated human-body-model ESD events without degradation. |
| Junction Capacitance | 175pF at 22V/1MHz - Low enough for DC power rail protection; not suitable for high-speed signal lines. |
| Dynamic Resistance | 20mΩ (8/20μs) - Enables low-voltage drop during surge, minimizing energy dissipation in the device itself. |
Pinout & Package
GS2974ACNE3 is housed in a Pb-free, RoHS-compliant DFN 1.6mm × 1.6mm × 0.55mm 6-lead package with exposed thermal pad (not electrically connected). All six pins are required for full surge rating: Pins 1–3 serve as low-inductance ground return paths; Pins 4–6 form a parallel input node for the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground | Three parallel GND terminals reduce total path inductance and distribute surge return current to maintain clamping integrity. |
| Pins 4, 5, 6 | Input (Protected Line) | Three parallel anode-equivalent terminals connect directly to the 22V bus; all must be routed with equal-length, low-impedance traces. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based transient shunting | Replaces traditional TVS diodes with active switching; enables flat clamping curve instead of linear VC = VBR + IPP×RDYN rise. |
| Temperature-stable clamping | Clamps at 27.5–28V from –40°C to +125°C - eliminates derating concerns in automotive or industrial ambient environments. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) - sustains 40A surges without thermal runaway or parametric shift. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - minimizes IR drop and localized heating during multi-cycle surge stress. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C receptacles against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping at 40A and +125°C - prevents controller latch-up or gate oxide damage where standard TVS would exceed 38V. |
Use Scenario: Shielding e-fuse or load switch inputs in remote meters, robotics, and IoT edge nodes from 1kV/42Ω line surges. IC Role / Device Role / Timing Role: Front-end transient suppressor upstream of integrated load switches like HS2950P or TPS2594L. Use Value: Limits voltage seen by switch's internal FET to ≤28V - avoids overvoltage failure while enabling compact PCB layout with minimal trace inductance. |
| Notebook/Tablet DC Power Rail Protection | Storage Device 22V Backup Power Line Protection |
Use Scenario: Securing 22V auxiliary rails powering SSD controllers, display drivers, or battery charging circuits in thin-client platforms. IC Role / Device Role / Timing Role: Standalone EOS guard on non-switched DC rails where space-constrained DFN placement is critical. Use Value: 1.6×1.6mm footprint saves >60% board area vs. SO-8 TVS solutions - enables routing under BGA packages or near connectors. |
Use Scenario: Safeguarding 22V backup power inputs in NVMe SSDs or enterprise storage enclosures against field-induced transients. IC Role / Device Role / Timing Role: Secondary protection layer after primary front-end filtering, before voltage regulators or PMIC inputs. Use Value: 175pF capacitance avoids signal integrity issues on DC rails - unlike sub-1pF TVS used for data lines, this value is optimized for power integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical electrical specs, same DFN 1.6×1.6mm package, identical pinout and marking code "T22" - confirmed drop-in replacement per Semtech documentation. | No functional difference; used interchangeably in USB-C PD reference designs and industrial schematics. | Select GS2974ACNE3 when requiring Aetrix's traceable sourcing, volume procurement support, or lifecycle continuity management. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 30V clamping, smaller 0.6×0.6mm 2-pin DFN - not pin-compatible and lacks multi-terminal surge sharing. | Suitable only for CC/SBU lines in USB-C, not for 22V power rails; cannot handle 40A surges or sustain industrial temperature range. | Choose uClamp2411ZA only for low-capacitance, low-current auxiliary signal protection - not a functional substitute for GS2974ACNE3. |
Compared with TDS2211P, GS2974ACNE3 offers identical protection performance and mechanical compatibility, enabling seamless supply chain substitution; versus uClamp2411ZA, it delivers 2× peak current capacity, 7V lower clamping, and triple-terminal architecture essential for robust 22V bus protection.

FAQ
What is the exact package type and dimensions of GS2974ACNE3?
GS2974ACNE3 uses a DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads. Pins 1–3 are ground terminals; Pins 4–6 are input terminals. The package is Pb-free, halogen-free, and RoHS/WEEE compliant with UL 94V-0 flammability rating. Pin 1 is marked with a laser dot on the top surface.
Does GS2974ACNE3 meet IEC 61000-4-5 surge immunity requirements?
Yes, GS2974ACNE3 is rated for 40A peak pulse current using the 8/20μs waveform per IEC 61000-4-5, and supports ±1kV combination wave testing (1.2/50μs voltage, 8/20μs current, RS = 42Ω). Its 27.5–28V clamping ensures compliance with industrial surge immunity standards for 22V systems.
How does GS2974ACNE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP×RDYN), GS2974ACNE3 maintains a nearly constant 27.5–28V clamp from 1A to 40A due to its FET-based architecture and decreasing RDS(on). This eliminates need for overrating IPP to meet voltage thresholds.
Can GS2974ACNE3 be used on high-speed data lines like USB SuperSpeed?
No, GS2974ACNE3 is not suitable for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on USB 3.x or PCIe lanes. It is designed exclusively for DC power or low-frequency I/O lines such as USB-C VBUS, load switch inputs, or 22V backup rails.
What is the maximum operating temperature range for GS2974ACNE3?
GS2974ACNE3 operates reliably from –40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range - a key advantage over conventional TVS diodes, whose clamping increases with temperature and reduces effective surge margin at elevated ambient conditions.
