Product details
Overview
GS2988-INTE3Z 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 a stable 27.5–28V clamping voltage across temperature and current range. It is used in USB Type-C PD input protection where precise clamping below controller damage thresholds is critical.
For engineers reviewing the GS2988-INTE3Z datasheet, pinout, applications, or equivalent options, this page provides verified package mapping, validated pin functions, confirmed clamping stability over temperature, real-world USB PD and load switch use cases, and two field-validated alternative suppressors with documented parameter trade-offs.
Technical Context
The GS2988-INTE3Z 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 at both 24A and 40A-due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with <20mΩ dynamic resistance and 175pF junction capacitance at 22V, enabling robust protection without signal integrity compromise on high-speed power buses. 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 maximize surge current handling and minimize parasitic inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - Matches nominal USB PD bus voltage and 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 range, preventing downstream IC damage. |
| Peak Pulse Current | 40A (8/20μs) - Meets IEC 61000-4-5 Level 4 industrial surge requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - Exceeds automotive and industrial ESD immunity standards without derating. |
| Junction Capacitance | 175pF at 22V, 1MHz - Low enough to avoid signal distortion on 20V power rails while maintaining robust surge energy absorption. |
| Dynamic Resistance | 20mΩ - Enables low-voltage drop during clamping, minimizing power dissipation and thermal stress during repeated surges. |
Pinout & Package
GS2988-INTE3Z is housed in a RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with six leads and no exposed thermal pad. All pins must be soldered for full surge rating: three GND pins provide low-inductance return paths, and three IN pins enable parallel connection to the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground terminals - must all be connected to a low-impedance ground plane via multiple vias to sustain 40A surge current. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals - tied directly to the protected 22V bus (e.g., VBUS in USB PD) to distribute surge current and reduce trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers flat clamping voltage (27.5–28V) across 1–40A surge range, unlike TVS diodes whose VC rises linearly with IPP. |
| Stable performance over temperature | Clamping voltage variation <0.5V from −40°C to +125°C - eliminates thermal derating calculations in industrial designs. |
| Low dynamic resistance | 20mΩ enables efficient energy diversion with minimal self-heating, supporting repeated surge events without degradation. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against fast repetitive bursts common in motor drives and PLC environments. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the VBUS line of a USB Type-C port supporting up to 20V/5A PD negotiation against lightning-induced surges and connector ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed immediately after the connector, clamping transients before they reach the PD controller and load switch. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - stays well below the 30–33V absolute maximum rating of common PD controllers like TUSB73x or STUSB4500. |
Use Scenario: Safeguarding the input of an industrial-grade load switch (e.g., TPS229xx, NIS513x) in remote metering or robotics systems exposed to 1kV/42Ω surges. IC Role / Device Role / Timing Role: Primary front-end protector that limits voltage seen by the load switch's internal FET gate oxide and drain-source junction. Use Value: Prevents catastrophic failure of the load switch by holding clamping voltage ≤28V - below typical 30V VDSS ratings and avoiding gate oxide stress. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Auxiliary Rail Protection |
|
Use Scenario: Securing the main 22V input rail of battery-backed IoT gateways operating in uncontrolled environments (e.g., outdoor smart sensors). IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection - eliminating need for multi-stage TVS+MOV designs. Use Value: Reduces BOM count and board area by 60% vs. discrete TVS+capacitor solutions while improving reliability through temperature-stable clamping. |
Use Scenario: Protecting auxiliary 22V rails in NVMe SSD enclosures or enterprise HDD backplanes subject to hot-plug transients and system-level surges. IC Role / Device Role / Timing Role: High-energy shunt device placed at board edge to clamp transients before they propagate into sensitive storage controller ICs. Use Value: 175pF capacitance avoids resonance issues on 22V power distribution networks, and 40A rating supports MIL-STD-461G CS115 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 and pinout; same DFN 1.6×1.6mm package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. GS2988-INTE3Z's standard reel quantity). | Same USB PD, load switch, and industrial power rail use cases; fully interchangeable in layout and schematic. | Select TDS2211P.C for volume procurement where reel size aligns with SMT line setup. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 30V clamping, and smaller 1.0×0.6mm DFN package - optimized for CC/SBU lines, not main VBUS. | Suitable only for low-current control lines (e.g., USB-C CC, SBU); insufficient for 40A VBUS protection. | Use uClamp2411ZA only for auxiliary signal-line protection; not a functional replacement for GS2988-INTE3Z in power-rail roles. |
Compared with TDS2211P.C, GS2988-INTE3Z offers identical protection performance and layout compatibility but may differ in reel logistics; compared with uClamp2411ZA, GS2988-INTE3Z provides 67% higher surge current rating and 2.5V lower clamping-critical for 22V power rail integrity.

FAQ
What is the exact package type and dimensions of GS2988-INTE3Z?
GS2988-INTE3Z uses a DFN package measuring 1.6mm × 1.6mm × 0.55mm with six leads and no exposed thermal pad. Pin 1 is marked by a laser dot. The land pattern requires full soldering of all three GND pins (1–3) and all three IN pins (4–6) to achieve rated 40A surge performance and low-inductance grounding.
Does GS2988-INTE3Z meet IEC 61000-4-5 Level 4 surge immunity?
Yes, GS2988-INTE3Z is rated for 40A peak pulse current with 8/20μs waveform per IEC 61000-4-5, which satisfies Level 4 (2kV open-circuit, RS = 42Ω, CS = 0.5μF) for 22V systems. Its 27.5–28V clamping voltage ensures protected circuits remain within safe operating limits during such events.
How does GS2988-INTE3Z 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-INTE3Z uses a triggered FET architecture that maintains 27.5–28V clamping from 1A to 40A. This eliminates thermal derating and ensures consistent protection across ambient temperatures from −40°C to +125°C.
Can GS2988-INTE3Z be used on USB-C superspeed differential pairs?
No, GS2988-INTE3Z is not suitable for USB-C superspeed (TX/RX) lines due to its 175pF junction capacitance, which would distort high-speed signals. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). GS2988-INTE3Z is intended exclusively for VBUS and other 22V power or single-ended I/O lines.
What is the maximum continuous reverse leakage current for GS2988-INTE3Z at 22V?
At VRWM = 22V and TA = 25°C, GS2988-INTE3Z exhibits a reverse leakage current of 130–600nA. This ultra-low leakage ensures negligible standby power loss in always-on industrial and IoT applications, and remains stable across the full −40°C to +125°C operating range.
