Product details
Overview
GS2989-INTE3Z from Semtech is a Transient Diverting Suppressor IC 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, Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the GS2989-INTE3Z datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability data across temperature and current, and validated alternatives for 22V bus protection design.
Technical Context
The GS2989-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-from 24A to 40A and across –40°C to +125°C due to decreasing RDS(on) under surge.
It operates with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and exhibits only 175pF junction capacitance at 22V/1MHz. Its 6-pin DFN package integrates three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3) to minimize parasitic inductance and maximize surge current handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage of protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream 24V-rated components (e.g., USB PD controllers, load switches) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness requirements for external connectors. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and low voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for VBus protection without distorting power delivery signaling (e.g., USB PD communication). |
| Operating Temp | –40°C to +125°C - supports deployment in extended-temperature industrial, automotive, and outdoor IoT environments. |
Pinout & Package
GS2989-INTE3Z is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals must be connected: Pins 1–3 serve as low-inductance ground return paths; Pins 4–6 form a parallel, low-impedance input node for the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | Ground (GND) | Three parallel GND terminals reduce total path inductance and distribute surge return current to maintain stable clamping under 40A pulses. |
| Pins 4, 5, 6 | Input (IN) | Three parallel input terminals connect directly to protected VBus or power rail-mandatory connection for full 40A rating and optimal ESD coupling suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A and remains stable across –40°C to +125°C-enables reliable protection without derating. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during surge, preventing voltage overshoot beyond 28V even at 40A peak. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) supports repeated lightning-surge events per IEC 61000-4-5 without degradation. |
| Ultra-low leakage | ≤600nA at 22V enables use on always-on power rails without measurable standby current penalty. |
| DFN-6 space efficiency | 1.6mm × 1.6mm footprint saves >60% board area vs. comparable SO-8 or SOT-23 TVS solutions while improving thermal and electrical performance. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the VBus line of USB Type-C ports supporting up to 20V/5A PD negotiation against ESD, lightning surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary high-energy shunt protector placed adjacent to the Type-C connector, clamping transients before they reach the PD controller or buck converter. Use Value: Maintains 27.5–28V clamping across temperature and current-prevents false overvoltage shutdowns and eliminates need for oversized TVS devices. |
Use Scenario: Safeguarding the input of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and programmable logic controllers exposed to field wiring surges. IC Role / Device Role / Timing Role: Front-end EOS suppressor that limits voltage seen by the load switch's internal FET gate oxide and drain-source junction. Use Value: Keeps clamping voltage below 30V-ensuring safe operation of 30V-rated load switches even at 125°C ambient and 40A surge. |
| IoT Edge Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
|
Use Scenario: Securing 22V auxiliary power rails in battery-backed smart sensors and gateways subjected to ESD during field servicing and conducted surges via long cables. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks-provides fast turn-on (<1ns trigger latency) and low-capacitance interface to 22V LDOs or PMICs. Use Value: 175pF capacitance avoids signal integrity issues on shared power rails; ±30kV ESD rating eliminates need for secondary ESD arrays. |
Use Scenario: Protecting 22V supercapacitor or LiFePO₄ backup supplies in enterprise SSDs and NVMe modules against EOS during hot-swap or power-fail recovery. IC Role / Device Role / Timing Role: Standby-mode protector that remains non-conductive until surge detection-preserving backup energy while blocking transients from reaching storage cells. Use Value: 130–600nA leakage at 22V minimizes self-discharge; flat clamping prevents overvoltage stress on backup capacitor dielectrics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Identical electrical specs, same DFN-6 package, identical marking (T22), and fully compatible pinout-manufactured by Semtech as direct variant. | No functional difference; used interchangeably in USB PD and industrial designs per Semtech's ordering documentation. | Select TDS2211P.C when sourcing from standard Semtech distribution channels; GS2989-INTE3Z may reflect specific end-customer or program-level traceability. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher 33V clamping at 24A, and 0.25pF capacitance-optimized for CC/SBU lines, not VBus. | Designed for low-capacitance data-line protection-not rated for 40A surges or VBus power rail duty. | Use uClamp2411ZA only for auxiliary signal lines (CC, SBU); GS2989-INTE3Z remains mandatory for main 22V power rail protection. |
Compared with TDS2211P.C, GS2989-INTE3Z offers identical protection performance and layout compatibility; versus uClamp2411ZA, it delivers 67% higher surge current capacity and 20% lower clamping voltage-making it the sole suitable choice for 22V power rail EOS hardening.

FAQ
What is the exact clamping voltage of GS2989-INTE3Z at 40A surge current?
The GS2989-INTE3Z clamps at 27.6–28V under 40A peak pulse current (8/20μs waveform, 2Ω source impedance), as guaranteed by design and confirmed in the official datasheet. This value remains stable across –40°C to +125°C ambient, distinguishing it from conventional TVS diodes whose clamping rises with temperature and current.
Is GS2989-INTE3Z pin-compatible with TDS2211P.C?
Yes-GS2989-INTE3Z shares identical pin configuration, DFN-6 package dimensions (1.6mm × 1.6mm), terminal assignment (Pins 1–3 = GND, Pins 4–6 = IN), and solder land pattern with TDS2211P.C. Both parts are manufactured by Semtech and intended for drop-in replacement in existing layouts.
Can GS2989-INTE3Z protect USB PD 3.0 VBus lines operating up to 20V?
Yes-GS2989-INTE3Z has a 22V reverse stand-off voltage and clamps at ≤28V during 40A surges, providing 2V margin below the absolute maximum rating of common USB PD 3.0 controllers. Its flat clamping behavior ensures consistent protection even at elevated temperatures encountered in compact portable enclosures.
What is the maximum junction temperature rating for GS2989-INTE3Z?
The GS2989-INTE3Z has a junction temperature range of –55°C to +150°C, with continuous operation specified from –40°C to +125°C ambient. Its FET-based architecture maintains clamping stability across this full range, unlike silicon avalanche TVS diodes whose performance degrades above 85°C.
Does GS2989-INTE3Z require a thermal pad or heatsink for 40A surge handling?
No-GS2989-INTE3Z dissipates surge energy primarily through its low-RDS(on) FET channel, not junction heating. The datasheet explicitly states no thermal pad is needed; instead, low-inductance PCB layout (multiple vias to ground plane, short traces to connector) is critical for maintaining 40A capability and sub-1ns response.
