Product details
Overview
GS3490-INTE3D 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, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the GS3490-INTE3D datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for 22V bus protection in high-reliability embedded and USB PD systems.
Technical Context
The GS3490-INTE3D implements a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and drives the shunt FET into low-RDS(on) conduction. Unlike conventional TVS diodes, its clamping voltage remains nearly constant - 27.5–28V - across 24A to 40A peak pulse current and from –40°C to +125°C operating temperature.
It operates with a 22V reverse stand-off voltage (VRWM) and 25–27.9V breakdown voltage (VBR), delivering <600nA leakage at VRWM, 1120W peak pulse power handling, and ultra-low 20mΩ dynamic resistance measured between 1A and 40A (8/20μs). Its functional architecture eliminates thermal derating limitations typical of junction-based TVS devices.

| FET-based shunt topology | Replaces PN-junction TVS with surge-rated MOSFET, reducing energy dissipation in silicon junction and improving reliability under repeated surges |
| Low dynamic resistance | 20mΩ enables near-linear current sharing across pins 4–6 and minimizes IR drop during transient conduction |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against fast repetitive bursts in motor drives and PLCs |
| Space-efficient packaging | 1.6mm × 1.6mm DFN footprint saves >60% board area vs. comparable SO-8 or SOT-23 TVS solutions |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20V–22V VBUS lines in USB-C receptacles where PD negotiation occurs and lightning-induced surges may exceed 1kV. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed adjacent to connector, clamping transients before they reach USB PD controller and e-fuse ICs. Use Value: Maintains 27.5–28V clamping at full 40A and 125°C - prevents false overvoltage shutdown and ensures PD communication continuity during surge events. |
Use Scenario: Front-end protection of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT gateways exposed to induced surges on long cables. IC Role / Device Role / Timing Role: Shunt protector that limits voltage across load switch drain-source to safe levels (<28V), preventing internal FET avalanche failure. Use Value: Enables use of cost-optimized load switches rated only to 30V, eliminating need for higher-voltage (and higher-RDS(on)) alternatives. |
| Industrial Equipment Power Rail Protection | Notebook/Tablet DC Input Protection |
|

IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks, providing coordinated clamping without follow-on current risk. Use Value: Delivers 1120W peak pulse power handling in 2.56mm² footprint - reduces BOM count and improves surge test pass rate in compact enclosures. |
Use Scenario: Input protection for 20V DC adapters feeding notebook or tablet main power rails, where space constraints limit discrete protection options. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA) suppressor that avoids affecting adapter regulation loop stability or standby power budget. Use Value: Supports compliance with IEC 61000-4-2 Level 4 and IEC 61000-4-5 without requiring additional filtering or layout isolation. |
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 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 authorized Semtech distribution channels with standard reel packaging (3,000 pcs/reel) |
| uClamp2411ZA | 24V VRWM, lower 24A IPP rating, 12pF capacitance, optimized for CC/SBU lines - not rated for 40A or 22V bus-level protection | Designed for low-capacitance data-line protection (e.g., USB-C CC pins), not power-rail clamping | Use uClamp2411ZA only for auxiliary signal lines; GS3490-INTE3D remains required for main VBUS protection due to higher IPP and thermal stability |
Compared with TDS2211P.C, GS3490-INTE3D offers identical performance but may differ in traceability or tape-and-reel configuration; versus uClamp2411ZA, GS3490-INTE3D provides 67% higher peak current rating and 15× higher capacitance tolerance - making it suitable for power rail, not signal line, protection.

FAQ
What is the maximum continuous operating voltage for GS3490-INTE3D?
The GS3490-INTE3D has a reverse stand-off voltage (VRWM) of 22V, meaning it can continuously withstand up to 22V DC on its input terminals without triggering. This makes GS3490-INTE3D suitable for nominal 20V USB PD buses and 22V industrial auxiliary rails where sustained voltage operation is required prior to transient events.
How does GS3490-INTE3D achieve stable clamping voltage across temperature?
GS3490-INTE3D achieves stable clamping by using a surge-rated FET as the conduction element instead of a PN junction. Its trigger circuit activates the FET to conduct with extremely low RDS(on), resulting in clamping voltage dominated by the fixed trigger threshold - not junction characteristics. As confirmed in the datasheet, GS3490-INTE3D maintains 27.5–28V clamping from –40°C to +125°C at 40A.
Can GS3490-INTE3D replace standard TVS diodes in existing 22V designs?
Yes - GS3490-INTE3D is a drop-in replacement for 22V TVS diodes in power rail protection, provided the PCB layout accommodates its 6-pin DFN package and all six pins are properly connected (pins 1–3 to ground, pins 4–6 to input). Its constant clamping eliminates thermal derating calculations required for traditional TVS devices, simplifying design validation.
What is the recommended PCB layout for optimal surge performance with GS3490-INTE3D?
For optimal surge performance, place GS3490-INTE3D as close as possible to the protected connector. Connect all three GND pins (1, 2, 3) directly to a solid ground plane using ≥3 vias each, and tie all three IN pins (4, 5, 6) together with a short, wide trace. Avoid stubs or splits - the layout must ensure symmetrical current sharing to achieve the full 40A rating specified for GS3490-INTE3D.
Does GS3490-INTE3D meet IEC 61000-4-5 surge immunity standards?
Yes - GS3490-INTE3D is rated for 40A peak pulse current with an 8/20μs waveform and supports ±1kV combination wave testing (1.2/50μs voltage, 8/20μs current, RS = 42Ω), satisfying IEC 61000-4-5 Level 4 requirements. Its 1120W peak pulse power rating and stable clamping ensure reliable pass performance in industrial and commercial surge testing protocols for GS3490-INTE3D.
