Product details
Overview
GS6042-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 20mΩ dynamic resistance. It protects USB PD and Type-C VBus lines in industrial and portable electronics.
For engineers reviewing the GS6042-INTE3 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for load-switch input protection and high-voltage interface surge hardening.
Technical Context
The GS6042-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 across 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with stable 27.5–28V clamping up to 125°C, 175pF junction capacitance at 22V/1MHz, and <600nA reverse leakage at VRWM. The device is rated for 1120W peak pulse power and meets IEC 61000-4-4 (±4kV EFT) and IEC 61000-4-5 (±1kV unsymmetrical line surge).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - Matches nominal USB PD VBus 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) - Satisfies IEC 61000-4-5 Level 3/4 surge immunity requirements for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - Enables robust front-end protection for exposed connectors without additional staging. |
| Dynamic Resistance | 20mΩ - Ensures minimal voltage rise during high di/dt transients, critical for fast-rising lightning surges. |
| Junction Capacitance | 175pF at 22V/1MHz - Low enough for DC power rails; not suitable for high-speed data lines (e.g., USB SS). |
| Operating Temp | −40°C to +125°C - Supports extended-temperature deployment in automotive cabin modules and industrial PLCs. |
Pinout & Package
GS6042-INTE3 is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6mm × 1.6mm × 0.55mm with wettable flank terminations. The compact footprint enables placement directly at USB Type-C or industrial connector entry points.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three pins must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBus); parallel connection of all three pins ensures full 40A rating and uniform current distribution. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Delivers flat clamping voltage vs. current and temperature-unlike TVS diodes whose VC rises linearly with IPP and ambient heat. |
| Ultra-low dynamic resistance | 20mΩ enables sub-1V voltage rise across full 40A surge range, preserving downstream overvoltage margins. |
| High-energy surge rating | 1120W peak pulse power supports repeated 40A/8/20μs events without degradation-critical for field-deployed IoT gateways. |
| Stable leakage performance | <600nA at 22V up to +125°C avoids system-level quiescent current drift in battery-powered edge sensors. |
| DFN-6 wettable flank package | Enables automated optical inspection (AOI) and improves solder joint reliability in high-vibration industrial environments. |
Applications
| USB Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting 20–22V VBus lines in USB Type-C ports supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed between connector and PD controller or load switch. Use Value: Maintains 27.5–28V clamping across −40°C to +125°C, preventing false OVP trips and ensuring reliable PD handshake under thermal stress. |
Use Scenario: Safeguarding input terminals of high-side load switches (e.g., HS2950P) in remote meters and robotics control units. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by the switch's internal FET drain-source junction. Use Value: Prevents avalanche failure of load switch MOSFETs during 1kV/42Ω line surges by clamping below 30V-well under typical 30–40V VDSS ratings. |
| IoT Gateway Power Rail Protection | Tablet/Notebook VBus Conditioning |
|
Use Scenario: Securing 24V auxiliary power inputs in cellular-connected industrial gateways exposed to outdoor surge environments. IC Role / Device Role / Timing Role: Standalone transient suppressor on main DC input before DC-DC conversion stage. Use Value: Handles repeated 40A surges without parameter shift, enabling long-term field reliability without derating for temperature or aging. |
Use Scenario: Protecting internal VBus routing in thin-profile tablets where board space limits use of larger TVS arrays. IC Role / Device Role / Timing Role: Single-device solution replacing multi-chip TVS+capacitor networks for compact 22V rail hardening. Use Value: 1.6mm × 1.6mm footprint saves >60% area versus legacy SO-8 TVS, while delivering superior clamping stability across operating temperature. |
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 (T22), and shared Semtech qualification-functionally identical part number variant. | No functional difference; used interchangeably in BOMs per Semtech's ordering documentation. | Select TDS2211P.C when sourcing from authorized distributors with standard reel packaging (3,000 pcs/reel). |
| uClamp2411ZA | 24V working voltage, lower 22V clamping (typ. 22V @ 12A), but only rated for 12A IPP and lacks flat-clamp FET architecture. | Suitable for CC/SBU lines in USB-C, not for VBus or power rail protection requiring 40A handling. | Choose uClamp2411ZA only for low-current signal-line protection; GS6042-INTE3 remains mandatory for VBus and load-switch inputs. |
Compared with TDS2211P.C (identical function) and uClamp2411ZA (lower current, signal-line optimized), GS6042-INTE3 uniquely delivers 40A surge capability with temperature-invariant clamping-making it the sole qualified option for industrial 22V power rail hardening where sustained energy dissipation matters.

FAQ
What is the exact package type and dimensions of GS6042-INTE3?
GS6042-INTE3 uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with wettable flank terminations. Pin 1 is marked by a laser dot; pins 1–3 are GND, and pins 4–6 are the protected input node. This footprint matches JEDEC MO-229 and is compatible with standard reflow profiles for lead-free assembly.
Does GS6042-INTE3 meet IEC 61000-4-5 surge immunity standards?
Yes, GS6042-INTE3 is rated for ±1kV (1.2/50μs voltage, 8/20μs current, RS = 42Ω) on unsymmetrical lines per IEC 61000-4-5, and supports up to 40A (8/20μs) peak pulse current. Its 27.5–28V clamping ensures compliance with system-level surge test limits for industrial and commercial equipment.
How does GS6042-INTE3 differ from standard TVS diodes in clamping behavior?
Unlike TVS diodes-whose clamping voltage rises linearly with peak current (VC = VBR + IPP × RDYN)-GS6042-INTE3 uses a triggered FET architecture that maintains ~27.5–28V clamping from 24A to 40A and across −40°C to +125°C. This eliminates thermal derating and ensures consistent protection margin.
Can GS6042-INTE3 be used on USB SuperSpeed differential pairs?
No, GS6042-INTE3 is not suitable for USB SuperSpeed (TX/RX) lines. Its 175pF junction capacitance would severely degrade signal integrity. For those lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF). GS6042-INTE3 is intended exclusively for VBus, CC, SBU, or power-rail protection.
What is the maximum continuous reverse leakage current of GS6042-INTE3 at 125°C?
At VRWM = 22V and +125°C, GS6042-INTE3 exhibits ≤600nA reverse leakage current-verified per datasheet Table "Electrical Characteristics." This low leakage ensures minimal impact on system standby power in battery-backed IoT nodes and portable devices.
