Product details
Overview
GS1679-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 temperature and current range. It is deployed in USB Type-C PD bus protection to safeguard controllers from overvoltage transients.
For engineers reviewing the GS1679-INTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability under 40A surge, low dynamic resistance (20mΩ), 175pF junction capacitance at 22V, DFN 1.6×1.6mm package constraints, and compatibility with industrial and portable power delivery interfaces.
Technical Context
The GS1679-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-27.5–28V-across 24A to 40A peak pulse currents due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with reverse stand-off voltage of 22V, breakdown voltage of 25–27.9V, and reverse leakage ≤600nA at VRWM. Its functional architecture separates input (pins 4–6) and ground (pins 1–3) terminals to minimize parasitic inductance during transient conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage it can protect without leakage or degradation |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds standard USB interface ESD robustness requirements |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during high-current shunting, minimizing energy dissipation in the device |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with 22V power rail protection without signal integrity impact on adjacent low-speed lines |
Pinout & Package
GS1679-INTE3 is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with six terminals. The compact footprint supports high-density PCB layouts while maintaining thermal and surge performance via symmetric terminal grouping.
| 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-handling capability and minimize inductive impedance |
| Pins 4, 5, 6 | IN | Protected line input; tied together to distribute surge current across parallel paths and reduce trace inductance to the connector |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across 24–40A and −40°C to +125°C - eliminates derating concerns in thermally demanding environments |
| FET-based shunt architecture | Replaces traditional TVS diodes with lower dynamic resistance and superior thermal stability - avoids voltage rise with increasing IPP or temperature |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive fast transients in industrial control and IoT edge nodes |
| Low leakage | ≤600nA at 22V - prevents excessive quiescent current draw in battery-powered USB-C devices and remote sensors |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB-C receptacles supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Transient diverting suppressor placed between connector and PD controller or load switch input. Use Value: Maintains clamping at 27.5–28V even at 40A surge and 125°C ambient-prevents controller latch-up or gate oxide damage where standard TVS would exceed 38V. |
Use Scenario: Safeguarding enable and input pins of industrial-grade e-fuses (e.g., HS2950P) exposed to lightning-induced surges in metering or robotics. IC Role / Device Role / Timing Role: Primary front-end EOS protector on VIN or EN inputs of load switches handling 22V rails. Use Value: Limits voltage seen by internal FET gate oxide to <28V during ±1kV/42Ω combo-wave surges-avoids permanent gate rupture or parametric shift. |
| IoT Edge Node Power Rail Protection | Notebook/Tablet 22V System Bus Protection |
Use Scenario: Securing 22V auxiliary power rails in battery-backed smart sensors or gateway modules operating in electrically noisy factory environments. IC Role / Device Role / Timing Role: Standalone EOS suppressor on main system supply before PMIC input. Use Value: Delivers 40A surge handling in 1.6×1.6mm DFN-enables compact, ruggedized designs without sacrificing surge margin or thermal headroom. |
Use Scenario: Protecting 22V system rails in ultrabooks and tablets using USB-C PD charging, where space and thermal management are critical. IC Role / Device Role / Timing Role: Secondary protection layer after upstream fuse, directly at PMIC or buck converter input. Use Value: 175pF capacitance avoids resonance or filtering issues on 22V rails; stable clamping ensures consistent protection across seasonal ambient variations. |
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 pinout and marking (T22XX), same tape-and-reel packaging (3,000/reel) | No functional difference; TDS2211P.C is the commercial-grade variant with identical EOS performance and qualification level | Select GS1679-INTE3 when requiring Semtech's industrial temperature grade (−40°C to +125°C) and extended reliability screening per AEC-Q200 or industrial test plans |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, higher clamping (~30V), smaller 0.6×0.3mm DFN package, optimized for CC/SBU lines-not rated for 40A or 22V bus protection | Designed for low-capacitance data-line protection (CC/SBU), not power-rail duty; unsuitable for 40A surge or 22V continuous operation | Use uClamp2411ZA only for auxiliary signal lines; GS1679-INTE3 remains required for main 22V power rail protection where 40A surge capability is mandatory |
Compared with TDS2211P.C, GS1679-INTE3 offers identical surge performance but with enhanced industrial qualification; versus uClamp2411ZA, it provides 67% higher peak current rating and 2.5V lower clamping-making it the sole viable option for 22V bus-level protection in USB PD and industrial load-switch applications.

FAQ
What is the maximum continuous operating voltage for GS1679-INTE3?
The GS1679-INTE3 has a reverse stand-off voltage (VRWM) of 22V, meaning it is rated for continuous DC operation up to 22V without significant leakage or degradation. This makes it suitable for protecting 20V USB PD buses and other 22V nominal power rails. Exceeding this voltage risks increased reverse leakage and potential long-term reliability issues.
Does GS1679-INTE3 meet IEC 61000-4-5 surge immunity standards?
Yes, GS1679-INTE3 is rated for 40A peak pulse current with an 8/20μs waveform per IEC 61000-4-5, and also supports ±1kV combination wave (1.2/50μs voltage, 8/20μs current, RS = 42Ω). Its stable 27.5–28V clamping ensures downstream components remain within safe operating limits during these standardized surge events.
How does GS1679-INTE3 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes-whose clamping voltage rises linearly with peak pulse current (VC = VBR + IPP × RDYN)-GS1679-INTE3 uses a triggered FET architecture that maintains clamping at ~27.5–28V from 24A to 40A. This stability holds across −40°C to +125°C, eliminating thermal derating and enabling predictable protection margins.
What is the recommended PCB layout for optimal surge performance of GS1679-INTE3?
For best results, connect all three IN pins (4–6) via a single short, wide trace to the protected line, and tie all three GND pins (1–3) directly to a solid ground plane using multiple vias. Place GS1679-INTE3 as close as possible to the connector-ideally within 5mm-to minimize inductive coupling and ensure transient energy is shunted before propagating into the system.
Is GS1679-INTE3 compatible with automated SMT assembly processes?
Yes, GS1679-INTE3 uses a standard DFN 1.6×1.6mm package with exposed pad-less construction and lead-free, RoHS-compliant terminations. It is qualified for reflow soldering per J-STD-020 moisture sensitivity level (MSL) 1 and supports standard pick-and-place and reflow profiles used in high-volume electronics manufacturing.
