Product details
Overview
GS2989-INTE3 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 its full current and temperature range (−40°C to +125°C). It is deployed in USB Type-C PD bus protection where precise clamping below controller damage thresholds is critical.
For engineers reviewing the GS2989-INTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge current and temperature, low dynamic resistance (20 mΩ), junction capacitance (175 pF at 22V), and DFN 1.6×1.6mm 6-lead package compatibility with high-density USB and industrial PCB layouts.
Technical Context
The GS2989-INTE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under increasing transient current - not fixed dynamic resistance.
It operates across −40°C to +125°C with guaranteed clamping performance up to 40A (8/20μs) and ±1kV (1.2/50μs, RS = 42Ω) on unsymmetrical lines. Its functional architecture isolates protection path (pins 4–6 → pins 1–3) with no internal thermal pad required, dissipating energy directly in the shunt FET.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 22 V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction |
| Clamping Voltage (VC) | 27.5–28 V at 24–40 A (1.2/50μs + 8/20μs combo wave, RS = 2 Ω) - ensures downstream 24V-rated controllers remain within safe voltage margin |
| Peak Pulse Current (IPP) | 40 A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 industrial surge immunity |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds USB IF and industrial ESD immunity requirements |
| Dynamic Resistance (RDYN) | 20 mΩ (measured 1–40 A, 8/20μs) - enables flat clamping curve and minimal voltage rise under surge |
| Junction Capacitance (CJ) | 175 pF at 22 V, 1 MHz - low enough for 22V bus protection without signal integrity degradation |
| Operating Temperature | −40°C to +125°C - supports operation in automotive cabin, industrial control, and ruggedized IoT environments |
Pinout & Package
GS2989-INTE3 is housed in a RoHS-compliant DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed thermal pad (no internal thermal slug). All six terminals are surface-mount; pin 1 is marked by laser dot. The package supports tape-and-reel delivery (3,000 units/reel, 7″ reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current - all three must be connected to maximize current sharing and minimize parasitic inductance |
| Pins 4, 5, 6 | IN | Protected line input - tied together externally to interface with 22V bus or power rail; simultaneous connection ensures full 40A rating |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5 V across 24–40 A and −40°C to +125°C - eliminates derating uncertainty in thermal design |
| FET-based shunt topology | Replaces pn-junction TVS with <0.1 Ω effective RDS(on) - reduces voltage overshoot during fast-rising transients |
| Low dynamic resistance | 20 mΩ enables >95% of surge current to bypass protected ICs - critical for load switch input protection |
| High-energy surge rating | 1120 W peak pulse power (8/20μs) - sustains multiple industrial surges without degradation |
| Ultra-low leakage | Max 600 nA at 22 V - prevents battery drain in always-on IoT and portable applications |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V USB PD bus against lightning-induced surges and connector ESD during hot-plug events. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed between VBus and GND, upstream of PD controller and load switch. Use Value: Maintains clamping at ≤28 V across temperature and current - avoids false OVP trips and enables use of cost-optimized 24V-rated controllers. |
Use Scenario: Safeguarding input of industrial-grade load switches (e.g., HS2950P) against 1.2/50μs surges in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage stress on internal FET gate oxide and overvoltage protection circuitry. Use Value: Prevents latch-up or permanent damage to load switch during ±1kV surge events - extends field reliability without adding external crowbar circuits. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors exposed to EFT bursts (IEC 61000-4-4, ±4 kV). IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge immunity on compact PCBs with limited real estate. Use Value: Eliminates need for multi-stage protection (TVS + MOV + filter) - reduces BOM count and layout complexity while meeting IEC 61000-4-x suite. |
Use Scenario: Protecting 22V backup power inputs in NVMe SSDs and enterprise storage controllers against power-rail transients. IC Role / Device Role / Timing Role: High-reliability clamping device placed at board edge before PMIC or LDO regulators. Use Value: 175 pF capacitance avoids resonance with typical 10–100 μF bulk capacitors - preserves transient response without oscillation risk. |
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 1.6×1.6mm package, identical marking (T22 + date code), same tape-and-reel packaging (3,000/reel) | No functional difference - GS2989-INTE3 is Semtech's alternate ordering code for TDS2211P.C per official cross-reference documentation | Select TDS2211P.C when sourcing from distributors listing only that part number; both are functionally and physically interchangeable. |
| uClamp2411ZA | 24 V working voltage, lower 20 A IPP, higher 33 V clamping, SOD-323 package (smaller footprint but lower surge handling) | Targeted at CC/SBU lines in USB Type-C, not main VBus; insufficient for 40A industrial surges | Use only for low-energy signal-line protection; not suitable as direct replacement for GS2989-INTE3 in power-rail applications. |
Compared with TDS2211P.C (identical device) and uClamp2411ZA (lower-energy signal protector), GS2989-INTE3 provides verified 40A surge capability and stable 28V clamping essential for 22V power rail protection - making it the sole option among the three qualified for industrial-level IEC 61000-4-5 compliance.

FAQ
What is the exact package type and dimensions of GS2989-INTE3?
GS2989-INTE3 uses a DFN (Dual Flat No-lead) package measuring 1.6 mm × 1.6 mm × 0.55 mm with six terminals and no exposed thermal pad. Pin 1 is identified by a laser-marked dot. The land pattern follows Semtech's recommended layout with three GND pins (1–3) and three IN pins (4–6), all requiring solid copper connections for full 40A surge rating. GS2989-INTE3 is supplied in 7″ tape-and-reel format with 3,000 units per reel.
Does GS2989-INTE3 meet IEC 61000-4-5 Level 4 surge immunity?
Yes, GS2989-INTE3 is rated for 40A peak pulse current (8/20μs waveform) and ±1kV (1.2/50μs, RS = 42Ω) on unsymmetrical lines - satisfying IEC 61000-4-5 Level 4 requirements for industrial environments. Its 27.5–28V clamping voltage at 40A ensures protected devices remain within safe operating limits during full-rated surge events. GS2989-INTE3 achieves this without derating across temperature, unlike standard TVS diodes.
How does GS2989-INTE3 differ from traditional TVS diodes in clamping behavior?
GS2989-INTE3 uses a triggered FET shunt instead of a pn-junction, resulting in near-constant clamping voltage (27.5–28V) across its full 24–40A surge range and −40°C to +125°C operating temperature. Traditional TVS diodes exhibit linear VC = VBR + IPP × RDYN, causing clamping to rise with current and temperature. GS2989-INTE3's 20 mΩ dynamic resistance enables this flat response - a key differentiator confirmed in Semtech's Figure 3 clamping comparison.
Can GS2989-INTE3 be used for USB Type-C CC and SBU line protection?
No - GS2989-INTE3 is optimized for 22V power rail (VBus) protection and is not suitable for CC or SBU lines. Those low-voltage, high-speed signal lines require ultra-low-capacitance protectors like uClamp2411ZA (0.25 pF). GS2989-INTE3's 175 pF junction capacitance would severely degrade signal integrity on differential pairs. Its pin configuration (3-input/3-ground) and clamping threshold are specifically intended for high-energy bus protection, not signal-line ESD.
Is GS2989-INTE3 pin-compatible with other Semtech TDS devices like TDS2411P?
No - GS2989-INTE3 (22V-rated) is not pin-compatible with TDS2411P (24V-rated). Although both use the same DFN 1.6×1.6mm 6-lead package and share identical pinout (pins 1–3 = GND, pins 4–6 = IN), their electrical specifications differ: TDS2411P has VRWM = 24 V, VBR = 27–30 V, and VC = 30–31 V. Substituting them requires validation of system overvoltage margins. GS2989-INTE3 must be used where 22V working voltage and 28V clamping are specified.
