Product details
Overview
GS2988-INTE3D from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated I/O or power lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 27.5–28V under 40A 8/20μs surge, and maintains stable clamping across –40°C to +125°C - enabling robust USB Type-C PD bus protection in industrial and mobile systems.
For engineers reviewing the GS2988-INTE3D datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, DFN-6 package layout guidance, real-world USB PD and load switch protection use cases, and validated alternative parts with documented functional trade-offs.
Technical Context
The GS2988-INTE3D 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) across 24–40A peak pulse current due to decreasing RDS(on) under surge stress.
It operates over –40°C to +125°C with <20mΩ dynamic resistance and 175pF junction capacitance at 22V reverse bias. Its 6-pin DFN 1.6×1.6×0.55mm package integrates three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3), requiring all six pins to be connected for full 40A surge rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and protects downstream 22V-tolerant controllers without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below typical 30V damage threshold of USB PD controllers across full temperature range. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Level 4 system-level ESD requirements for consumer and industrial ports. |
| Peak Pulse Current | 40A (8/20μs) - satisfies IEC 61000-4-5 Level 3 surge immunity (±1kV, RS=42Ω) for industrial equipment interfaces. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during surge conduction, minimizing energy dissipation in protected ICs. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with DC-biased power rails; not suitable for high-speed data lines without additional low-C protection. |
| Operating Temp. | –40°C to +125°C - supports operation in automotive cabin, industrial control, and ruggedized IoT environments. |
Pinout & Package
GS2988-INTE3D is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All six leads are soldered to PCB for maximum surge current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected with low-inductance vias to ground plane. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBus); all three required to achieve rated 40A capability. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A surge - eliminates need for oversized IPP margin to meet voltage safety limits. |
| FET-based shunt topology | Surge energy diverted through low-RDS(on) channel instead of PN-junction - avoids thermal runaway and de-rating at high ambient temperatures. |
| Multi-terminal input & ground | Three parallel IN and GND pins reduce trace inductance and distribute current - critical for maintaining 40A rating in compact layouts. |
| Stable performance over temperature | Clamping voltage drift <±0.2V from –40°C to +125°C - enables reliable protection without thermal derating calculations. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C receptacles supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and PD controller or e-fuse IC. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents latch-up or gate oxide damage in PD controllers where standard TVS would exceed 35V. |
Use Scenario: Safeguarding input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and factory automation. IC Role / Device Role / Timing Role: Front-end transient shunt that limits voltage seen by load switch FET's drain-source rating. Use Value: Clamps below 28V during lightning-induced surges - avoids avalanche failure or SOA violation in integrated load switch MOSFETs. |
| IoT Device DC Power Rail Protection | Notebook/Tablet Main Power Input Protection |
Use Scenario: Securing 22V-rated auxiliary power inputs in battery-powered edge sensors and wireless gateways. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection per IEC 61000-4-2/4/5. Use Value: Delivers ±4kV EFT immunity and ±30kV ESD in 1.6×1.6mm footprint - replaces multi-component TVS+filter networks. |
Use Scenario: Hardening 20V DC-in ports on ultrabooks and 2-in-1 tablets against accidental adapter surges and connector hot-plug transients. IC Role / Device Role / Timing Role: First-line defense before buck converter or battery charge management IC. Use Value: 1120W peak pulse power rating handles worst-case 1.2/50μs + 8/20μs combination waveforms - meets EN 61000-4-5 Class 3 compliance. |
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 with same revision history. | No functional difference - direct material equivalence; used interchangeably in BOMs and procurement. | Select TDS2211P.C when sourcing from authorized Semtech channels with full traceability and warranty coverage. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping, smaller 0.6×0.6mm DFN-2 package - optimized for CC/SBU lines, not main VBus. | Not suitable for 22V power rail protection; intended for low-capacitance, low-current signal line protection only. | Choose uClamp2411ZA only for auxiliary USB-C lines (CC, SBU); avoid for VBus due to insufficient IPP and elevated clamping. |
Compared with GS2988-INTE3D, TDS2211P.C offers identical protection performance and board-level compatibility, while uClamp2411ZA serves a different voltage/current class and cannot replace GS2988-INTE3D in main power rail applications without risking overvoltage damage.

FAQ
What is the exact package type and dimensions of GS2988-INTE3D?
GS2988-INTE3D uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed copper pad. 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 for low-inductance surge return - critical to achieving the full 40A rating.
Does GS2988-INTE3D meet IEC 61000-4-5 Level 3 surge immunity?
Yes, GS2988-INTE3D is rated for ±1kV (1.2/50μs voltage, 8/20μs current, RS = 42Ω) per IEC 61000-4-5, satisfying Level 3 industrial surge requirements. Its 40A 8/20μs capability and 27.5–28V clamping ensure protected circuits remain within safe operating voltage margins during standardized surge events.
Can GS2988-INTE3D be used on high-speed data lines like USB SuperSpeed or DisplayPort?
No, GS2988-INTE3D is not suitable for high-speed data lines. With 175pF junction capacitance at 22V, it would severely degrade signal integrity on >100MHz differential pairs. For USB SS, DP, or HDMI lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), which are designed specifically for signal-line protection.
How does GS2988-INTE3D differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS2988-INTE3D uses a triggered FET shunt that maintains near-constant clamping (27.5–28V) from 24A to 40A. This eliminates the need to overspecify IPP just to hold VC below IC damage thresholds - especially valuable at elevated temperatures where TVS clamping degrades.
Is GS2988-INTE3D pin-compatible with other Semtech TDS devices like TDS2411P?
No, GS2988-INTE3D is not pin-compatible with TDS2411P. While both are 6-pin DFN devices, TDS2411P is rated for 24V working voltage and has different internal trigger thresholds and clamping characteristics. Substituting them requires validation of voltage margin, surge rating, and thermal behavior - they are functionally distinct parts within the TDS family.
