Product details
Overview
GS2975ACNE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O 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 PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the GS2975ACNE3 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for EOS protection design-in.
Technical Context
The GS2975ACNE3 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) under surge conditions.
It operates from –40°C to +125°C with stable 27.5–28V clamping at 40A, 22V reverse stand-off voltage, and 175pF junction capacitance at 22V/1MHz - enabling robust protection without signal integrity compromise in high-speed bus interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - maximum continuous operating voltage before conduction begins; matches USB PD 20V nominal + margin. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - limits transient overvoltage to safe levels for downstream 24V-tolerant ICs. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD systems. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 requirements for handheld and connector-facing applications. |
| Dynamic Resistance | 20 mΩ - ensures minimal voltage rise under high-current transients, enabling tighter clamping control than TVS diodes. |
| Junction Capacitance | 175 pF at 22V/1MHz - low enough to avoid signal distortion on 22V power rails while maintaining robust surge handling. |
Pinout & Package
GS2975ACNE3 is housed in a RoHS-compliant DFN-6 package measuring 1.6 mm × 1.6 mm × 0.55 mm, with exposed thermal pad not required - energy dissipation occurs within the silicon FET structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to maximize current sharing and minimize inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., USB VBus, load switch VIN); parallel connection ensures uniform current distribution during 40A transients. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage vs. current | 27.5–28 V across full 24–40A rated range - eliminates need for over-spec'ed IPP to meet voltage thresholds. |
| Temperature-stable clamping | No increase in VC from –40°C to +125°C - enables reliable protection in automotive under-hood or industrial ambient conditions. |
| FET-based shunt architecture | Replaces PN-junction TVS with low-RDS(on) switch - reduces thermal stress and improves longevity under repeated surges. |
| Low dynamic resistance | 20 mΩ - minimizes IR drop during surge, preserving voltage margin for downstream 24V-rated components. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting USB Type-C VBus lines operating up to 20V nominal with 22V tolerance against lightning-induced surges and hot-plug ESD. IC Role / Device Role / Timing Role: Primary EOS suppressor placed adjacent to the Type-C connector, clamping transients before they reach the PD controller or e-fuse. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents damage to 24V-tolerant PD controllers where conventional TVS would exceed safe voltage margins. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) exposed to 40A surges in remote meters or robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage across the load switch's internal FET drain-source junction during EOS events. Use Value: Prevents gate oxide rupture and latch-up in the protected load switch by holding clamping voltage below its absolute maximum rating. |
| IoT Device Power Rail Protection | Notebook/Tablet DC Power Input Protection |
Use Scenario: Securing 22V-rated power inputs in battery-powered IoT gateways subjected to EFT bursts and contact ESD in field deployments. IC Role / Device Role / Timing Role: Single-device solution for IEC 61000-4-4 (±4kV EFT) and IEC 61000-4-2 (±30kV ESD) compliance on main supply rail. Use Value: Delivers 175pF capacitance and 22V working voltage - avoids filtering trade-offs while meeting Class 4 immunity without additional RC networks. |
Use Scenario: Hardening 20V DC input rails in ultrabooks and tablets against accidental AC adapter surges and connector hot-swap transients. IC Role / Device Role / Timing Role: High-energy clamping device placed between barrel jack/USB-C port and system PMIC input stage. Use Value: Enables compact 1.6×1.6mm footprint with no thermal pad - saves PCB area versus SOD-123 or SMA TVS solutions while delivering superior clamping consistency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Identical electrical specs, same DFN-6 package, identical marking code T22; manufactured by Semtech as direct variant. | No functional difference - used interchangeably in USB PD and industrial designs per Semtech ordering documentation. | Select when requiring tape-and-reel delivery (3,000 pcs/reel) and standard Semtech logistics traceability. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but lower 20A IPP (8/20μs); uses standard TVS architecture, not FET-based shunt. | Suitable for CC/SBU lines in USB-C, not VBus - higher clamping voltage drift with temperature and current limits use to lower-energy paths. | Choose only for auxiliary signal lines where 20A surge capability suffices and cost sensitivity outweighs clamping stability needs. |
Compared with TDS2211P.C, GS2975ACNE3 offers identical performance and form factor but may differ in date-code marking or reel packaging; compared with uClamp2411ZA, GS2975ACNE3 provides 2× peak current rating and thermally stable clamping essential for primary power rail protection.

FAQ
What is the exact package type and dimensions of GS2975ACNE3?
GS2975ACNE3 uses a 6-pin DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed pad not required. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern follows Semtech's recommended layout with multiple vias to ground plane for optimal surge current handling.
Does GS2975ACNE3 meet IEC 61000-4-5 surge immunity standards?
Yes, GS2975ACNE3 is rated for 40A peak pulse current with 8/20μs waveform per IEC 61000-4-5, and supports ±1kV combination wave (1.2/50μs voltage, 8/20μs current, RS = 42Ω) for unsymmetrical lines - satisfying Level 4 industrial surge requirements.
How does GS2975ACNE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), GS2975ACNE3 maintains 27.5–28V clamping from 24A to 40A due to its FET-based shunt architecture and decreasing RDS(on), ensuring consistent protection across temperature and surge magnitude.
Can GS2975ACNE3 be used on USB Type-C superspeed differential pairs?
No - GS2975ACNE3 is intended for VBus or power-line protection, not high-speed data lines. Its 175pF junction capacitance would degrade signal integrity on SS TX/RX lanes. For those, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF).
What is the maximum operating temperature range for GS2975ACNE3?
GS2975ACNE3 is specified for continuous operation from –40°C to +125°C ambient, with clamping voltage and leakage current fully characterized across this range. Junction temperature can reach +150°C, supporting use in thermally demanding industrial and automotive under-hood environments.
