Product details
Overview
GS3441-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 PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the GS3441-INTE3 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, clamping stability across temperature and current, and real-world implementation insights for high-reliability surge protection design.
Technical Context
The GS3441-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-27.5–28V-from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with stable 22V reverse stand-off voltage, <600nA leakage at VRWM, and 175pF junction capacitance at 22V/1MHz. Its thermal robustness and low dynamic resistance enable reliable protection where traditional TVS devices exhibit rising clamping voltage with temperature and current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - Matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - Stays below 30V damage threshold of common load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - Eliminates need for secondary ESD stages in USB Type-C connectors. |
| Dynamic Resistance | 20mΩ - Enables minimal voltage rise during surge, critical for maintaining safe margin below IC absolute maximum ratings. |
| Junction Capacitance | 175pF at 22V/1MHz - Low enough for DC power line protection without affecting load switch response or regulation loop stability. |
| Operating Temperature | –40°C to +125°C - Fully specified performance across automotive-grade and extended industrial ambient ranges. |
Pinout & Package
GS3441-INTE3 is housed in a compact, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals must be connected per functional role to achieve rated 40A surge capability and optimal thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be connected to minimize inductance and maximize current sharing. |
| Pins 4, 5, 6 | IN | Protected input node - connects directly to VBus or power line; all three pins are internally tied and must be shorted externally for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A - eliminates design uncertainty caused by TVS voltage drift under surge stress. |
| Temperature-stable clamping | 27.5–28V clamping maintained from –40°C to +125°C - ensures consistent protection margin across full operating range. |
| Low dynamic resistance | 20mΩ enables sub-1V IR drop at 40A - preserves system-level voltage integrity during surge events. |
| High-energy EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive fast transients in motor drives and PLC environments. |
| DFN-6 footprint | 1.6mm × 1.6mm area - saves >60% board space vs. SO-8 or SOT-23 alternatives while enabling high-current PCB routing. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting the 20–22V VBus line in USB Type-C ports supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary high-energy EOS suppressor placed between connector and PD controller/load switch. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents latch-up or gate oxide damage in downstream PD controllers. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end surge diverter that limits transient voltage before it reaches the load switch's internal FET. Use Value: Keeps clamping voltage below 30V - avoids exceeding the 32V absolute max rating typical of industrial load switches. |
| IoT Edge Node Power Rail Protection | Storage Device 24V Backup Supply Protection |
|
Use Scenario: Securing 22V auxiliary rails in battery-backed IoT gateways exposed to lightning-induced surges.

Use Value: Delivers 1120W peak pulse power handling in 2.56mm² footprint - enables conformal coating and sealed enclosure integration. |
Use Scenario: Protecting 24V backup power inputs in NVMe SSD enclosures and enterprise storage controllers. IC Role / Device Role / Timing Role: Standoff protector for hot-swap and insertion transients on redundant power inputs. Use Value: 175pF capacitance avoids signal integrity issues on high-speed control lines sharing the same PCB layer. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical electrical specs, pinout, and package - direct manufacturer-recommended replacement for GS3441-INTE3. | Same use cases: USB PD, load switch, industrial 22V rail protection. | Select when sourcing from Semtech-authorized channels with full traceability and revision-controlled documentation. |
| uClamp2411ZA | 24V working voltage, ±30kV ESD, but lower 20A IPP rating and higher 33V clamping at 20A. | Better suited for CC/SBU lines in USB Type-C; insufficient for 40A VBus protection. | Choose only for lower-energy signal-line protection where 27V clamping and 40A rating are not required. |
Compared with TDS2211P and uClamp2411ZA, GS3441-INTE3 delivers identical high-current clamping performance and package compatibility as TDS2211P, while uClamp2411ZA serves distinct low-capacitance, lower-IPP roles-making GS3441-INTE3 the optimal choice for 22V power rail surge hardening where 40A capability and 28V clamping are mandatory.

FAQ
What is the exact package type and dimensions of GS3441-INTE3?
GS3441-INTE3 uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad. Pin 1 is marked by a laser dot; pins 1–3 are GND, and pins 4–6 are IN. The land pattern requires full copper connection to both GND and IN pads to achieve rated 40A surge performance.
Does GS3441-INTE3 meet IEC 61000-4-5 surge immunity standards?
Yes, GS3441-INTE3 is rated for 40A peak pulse current with 8/20μs waveform per IEC 61000-4-5, and supports ±1kV combination wave (1.2/50μs voltage, 8/20μs current, RS = 42Ω) for unsymmetrical lines - satisfying Level 4 industrial surge requirements.
How does GS3441-INTE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN), GS3441-INTE3 maintains 27.5–28V clamping from 24A to 40A due to its FET-based shunt architecture and decreasing RDS(on), delivering predictable protection across full surge range and temperature.
Can GS3441-INTE3 be used on USB Type-C superspeed differential pairs?
No, GS3441-INTE3 is not suitable for USB SS TX/RX lines due to its 175pF junction capacitance. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); GS3441-INTE3 is intended exclusively for VBus, CC, SBU, or power rail protection.
What is the maximum operating temperature and thermal derating for GS3441-INTE3?
GS3441-INTE3 is fully specified from –40°C to +125°C with no derating required. Clamping voltage remains stable at 27.5–28V across this range, and peak pulse current rating holds at 40A - unlike TVS diodes whose IPP degrades above 85°C.
