Product details
Overview
GS2988-INTE3 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 ultra-low 20mΩ dynamic resistance. It protects USB Type-C PD buses, load switch inputs, and industrial interfaces where stable clamping under temperature and current stress is critical.
For engineers reviewing the GS2988-INTE3 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 clamping and thermal behavior differences.
Technical Context
The GS2988-INTE3 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 up to 40A and maintains <600nA reverse leakage at 22V. Its 175pF junction capacitance at 22V/1MHz and 20mΩ dynamic resistance enable low-voltage overshoot control in high-speed power bus applications without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges |
| 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 immunity mandates |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage rise under increasing surge current |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 20V power rails without affecting load switch response or PD negotiation timing |
| Operating Temperature | −40°C to +125°C - supports deployment in automotive cabin, industrial PLC, and outdoor IoT enclosures |
Pinout & Package
GS2988-INTE3 is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound. All pins must be soldered for full 40A surge rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; requires low-inductance PCB connection via multiple vias to internal ground plane |
| Pins 4, 5, 6 | IN | Protected line input - all three pins must be connected in parallel to the same bus node to achieve rated 40A capability and minimize trace inductance |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A surge range - eliminates design margin inflation needed with traditional TVS devices |
| FET-based shunt topology | Surge energy dissipated in low-RDS(on) channel instead of PN junction - enables stable performance up to +125°C ambient |
| Low dynamic resistance | 20mΩ measured between 1A–40A - reduces voltage overshoot during fast-rising transients (e.g., ESD, lightning-induced surges) |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive burst noise in motor drives and industrial comms |
| Space-optimized footprint | 1.6mm × 1.6mm DFN-6 - saves >60% board area vs. comparable SO-8 or SOT-23 TVS solutions while maintaining 1120W peak power rating |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD profiles against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at connector entry point, clamping transients before they reach PD controller or load switch. Use Value: Maintains 27.5–28V clamping across −40°C to +125°C - prevents false overvoltage shutdowns and ensures reliable PD negotiation under thermal stress. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters, robotics actuators, and programmable logic controllers exposed to field wiring surges. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage across the load switch's internal FET drain-source terminals during surge events. Use Value: Keeps clamping voltage below 30V - avoids gate oxide damage and latch-up in integrated load switches rated for ≤30V absolute max VDS. |
| IoT Edge Node Power Rail Protection | Industrial Storage Device Interface Protection |
|
Use Scenario: Securing 22V auxiliary power rails in battery-backed smart sensors and gateway modules deployed in uncontrolled environments (e.g., factory floors, outdoor kiosks). IC Role / Device Role / Timing Role: Single-component solution for combined ESD, EFT, and surge protection on always-on supply lines feeding MCU, PMIC, and wireless SoCs. Use Value: Delivers ±30kV ESD + ±4kV EFT + 40A surge in one 1.6×1.6mm device - eliminates need for cascaded TVS + RC filter networks and reduces BOM count by 2–3 parts. |
Use Scenario: Shielding SATA or PCIe 3.3V/12V auxiliary power lines in ruggedized SSD enclosures and NAS systems subjected to electrostatic discharge during maintenance or cable insertion. IC Role / Device Role / Timing Role: Low-capacitance (<200pF), high-power suppressor placed at backplane connector interface to prevent transient coupling into storage controller ICs. Use Value: 175pF capacitance at 22V ensures no measurable impact on 12V rail rise/fall time - preserves power sequencing integrity during hot-swap operations. |
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 and DFN-6 package; same manufacturer, same revision history; marked T22XX on top | No functional difference - direct Semtech-recommended alternate with identical tape-and-reel packaging (3,000 pcs/reel) | Select when requiring Semtech's standard production variant with full traceability and qualification documentation |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.5A; higher clamping (+7.5V), fixed RDYN, degrades above 85°C | Higher clamping voltage risks PD controller damage; unsuitable for sustained high-temp industrial operation | Acceptable only for cost-sensitive, non-critical 22V rails where 35.5V clamping is within downstream IC tolerance and ambient stays <70°C |
Compared with GS2988-INTE3, TDS2211P.C offers identical performance and sourcing continuity, while SMAJ22A trades clamping stability and thermal robustness for lower unit cost - making GS2988-INTE3 the preferred choice for USB PD, industrial load switches, and thermally demanding IoT deployments.

FAQ
What is the maximum continuous operating voltage for GS2988-INTE3?
The GS2988-INTE3 has a reverse stand-off voltage (VRWM) of 22V, meaning it reliably blocks voltages up to 22V DC in normal operation without leakage exceeding 600nA. This makes GS2988-INTE3 ideal for protecting 20V USB PD buses and 22V industrial auxiliary rails where sustained voltage compliance is required.
How does GS2988-INTE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN), GS2988-INTE3 uses a triggered FET shunt that maintains near-constant 27.5–28V clamping from 24A to 40A. This eliminates design margin uncertainty and improves protection predictability in high-surge environments.
Can GS2988-INTE3 be used to protect bidirectional data lines like USB CC or DP/DM?
No - GS2988-INTE3 is optimized for unidirectional 22V power or I/O line protection and lacks the sub-0.3pF capacitance required for high-speed differential data lines. For CC/SBU or DP/DM protection, Semtech recommends dedicated low-capacitance devices such as uClamp2411ZA or RClamp3371ZC alongside GS2988-INTE3 in full USB-C solutions.
What is the recommended PCB layout for achieving full 40A surge rating with GS2988-INTE3?
To achieve the rated 40A (8/20μs) performance, all three IN pins (4, 5, 6) must connect via a single low-inductance trace to the protected bus, and all three GND pins (1, 2, 3) must connect to a solid ground plane using ≥3 thermal vias. GS2988-INTE3 must be placed within 5mm of the connector to minimize parasitic inductance and prevent transient coupling.
Is GS2988-INTE3 compliant with RoHS and halogen-free standards?
Yes - GS2988-INTE3 is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound carries UL 94V-0 flammability rating, and lead finish is 100% matte tin, ensuring compatibility with lead-free reflow processes and environmental regulatory requirements for industrial and consumer products.
