Product details
Overview
GS2974ACNTE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or data lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance. It protects USB Type-C power delivery buses, load switch inputs, and industrial I/O interfaces where stable clamping under temperature and current stress is critical.
For engineers reviewing the GS2974ACNTE3 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world USB PD and load switch protection use cases, and two validated alternative suppressors with documented functional trade-offs.
Technical Context
The GS2974ACNTE3 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 across 24–40A (8/20μs) due to decreasing RDS(on), not fixed dynamic resistance.
It operates from −40°C to +125°C with <600nA reverse leakage at 22V, 175pF junction capacitance at 22V/1MHz, and maintains stable 27.5–28V clamping over temperature - a key differentiator versus standard TVS devices whose clamping rises with both current and ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below typical 30V damage threshold of USB PD controllers and load switches. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds USB IF and IEC 61000-4-2 Class 4 requirements. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during surge conduction, minimizing energy dissipation in the device. |
| Junction Capacitance | 175pF at 22V/1MHz - suitable for DC power rails and low-speed signal lines; not for >100MHz data paths. |
| Operating Temperature | −40°C to +125°C - supports extended-range industrial, automotive under-hood, and outdoor IoT deployments. |
Pinout & Package
GS2974ACNTE3 is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required per datasheet). All six terminals are electrically active: pins 1–3 form a common ground plane, pins 4–6 form a parallel input node for surge current routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path; all three must be connected to maximize surge current handling and minimize parasitic inductance. |
| 4, 5, 6 | IN | Parallel-connected input node for protected line (e.g., VBUS or load switch input); shared surge conduction path to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across full 24–40A surge range - eliminates design margin inflation needed with TVS diodes. |
| FET-based shunt topology | Surge energy diverted through low-RDS(on) channel instead of PN-junction - reduces thermal stress and improves longevity. |
| Temperature-stable clamping | Clamps at 27.5–28V from −40°C to +125°C - enables reliable protection in uncontrolled thermal environments. |
| High EFT immunity | Withstands ±4kV burst (IEC 61000-4-4, 5/50ns) - protects against switching noise in motor drives and PLCs. |
| Space-optimized footprint | 1.6mm × 1.6mm DFN-6 saves >60% board area vs. SO-8 TVS solutions - critical for USB Type-C connectors and compact IoT modules. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBUS lines in USB Type-C ports supporting up to 20V/5A PD negotiation, exposed to ESD events during hot-plug and lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed directly at connector, clamping transients before they reach PD controller ICs (e.g., TUSB73x, CYPD3177). Use Value: Maintains 27.5–28V clamping across temperature and current - avoids overvoltage damage to PD controllers rated for ≤30V absolute max. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., TPS229xx, AP22653) in remote meters, robotics, and factory automation systems. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by the load switch's internal MOSFET gate oxide and drain-source junction. Use Value: Prevents latch-up or permanent failure of the load switch during 1kV/42Ω IEC 61000-4-5 surges by holding clamping below 28V - well under typical 30–35V FET breakdown. |
| IoT Edge Node Power Rail Protection | Storage Device DC Bus Protection |
|
Use Scenario: Securing 22V-rated power inputs on battery-backed edge gateways and sensor hubs deployed outdoors or near EMI sources. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on main DC input, replacing multi-component TVS+MOV stacks. Use Value: Delivers ±30kV ESD, ±4kV EFT, and 40A surge capability in one 1.6mm² footprint - simplifies BOM and improves field reliability. |
Use Scenario: Protecting 22V auxiliary rails in NVMe SSD enclosures, SAS expanders, and enterprise HDD backplanes subject to hot-swap transients and system-level surges. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA) suppressor placed at power entry point to prevent data corruption or controller reset. Use Value: Stable clamping ensures no voltage overshoot triggers brown-out detection or resets storage controller logic during transient events. |
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-6 package, identical marking code "T22" - confirmed pin-to-pin and functionally equivalent per Semtech documentation. | No difference; used interchangeably in USB PD reference designs and industrial schematics. | Select when sourcing from Semtech-authorized channels with full traceability and lifecycle support. |
| SP1003-02HTG | TVS diode (not TDS architecture); 24V working voltage, 33.2V clamping at 30A, higher dynamic resistance (~150mΩ), 12pF capacitance. | Better for high-frequency signal lines (e.g., USB SS lanes) due to ultra-low capacitance, but clamping rises with temperature and current. | Choose only for low-capacitance signal protection; avoid for power rail clamping where stable voltage is required. |
Compared with GS2974ACNTE3, TDS2211P offers identical performance and drop-in compatibility, while SP1003-02HTG trades clamping stability for lower capacitance - making it unsuitable as a direct replacement for 22V power rail protection but viable for adjacent signal-line hardening.

FAQ
What is the exact package type and dimensions of GS2974ACNTE3?
GS2974ACNTE3 uses a DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with no exposed thermal pad. Pins 1–3 are GND, pins 4–6 are the parallel input node. Land pattern follows Semtech's recommended 1.45mm × 1.45mm solder pad layout with 0.30mm pitch and 0.50mm via clearance - critical for achieving full 40A surge rating.
Does GS2974ACNTE3 meet IEC 61000-4-5 Level 4 surge immunity?
Yes, GS2974ACNTE3 is rated for 40A peak pulse current with 8/20μs waveform per IEC 61000-4-5, which satisfies Level 4 (2kV open-circuit, 1kV into 42Ω source impedance) for industrial environments. Its 27.5–28V clamping ensures downstream components remain within safe operating voltage limits during such events.
How does GS2974ACNTE3 differ from standard TVS diodes in clamping behavior?
Unlike TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), GS2974ACNTE3 uses a triggered FET shunt that maintains ~27.5–28V clamping from 24A to 40A and across −40°C to +125°C - eliminating design uncertainty caused by temperature- and current-dependent voltage overshoot.
Can GS2974ACNTE3 be used on USB SuperSpeed differential pairs?
No - GS2974ACNTE3 has 175pF junction capacitance, making it unsuitable for USB 3.x/PCIe high-speed lanes. For those, Semtech recommends low-capacitance TVS like RClamp3371ZC (<0.25pF). GS2974ACNTE3 is intended exclusively for VBUS, CC, SBU, or load switch power inputs - not signal integrity-critical paths.
Is GS2974ACNTE3 RoHS and REACH compliant?
Yes, GS2974ACNTE3 is Pb-free, halogen-free, and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Its molding compound meets UL 94V-0 flammability rating, and marking includes date code and "T22" identification per Semtech's tape-and-reel specification.
