Product details

Overview

GS1679-INE3 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 stable 27.5–28V clamping across its full current and temperature range (−40°C to +125°C). It is deployed in USB Type-C PD bus protection where low, temperature-invariant clamping prevents damage to voltage-sensitive controllers.

For engineers reviewing the GS1679-INE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, dynamic resistance (<20 mΩ), junction capacitance (175 pF), and DFN 1.6×1.6mm 6-lead layout compatibility with high-density USB and industrial interfaces.

Technical Context

The GS1679-INE3 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 due to decreasing R_DS(on) under increasing current - not fixed dynamic resistance.

It operates across −40°C to +125°C with guaranteed clamping at 27.5–28V for 24A and 40A (1.2/50μs + 8/20μs combination waveform, R_S = 2Ω), and maintains <600 nA reverse leakage at 22V. Its 175 pF junction capacitance at 22V/1MHz supports robustness without compromising signal integrity on DC power rails.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22 V - defines maximum continuous DC operating voltage of protected line without leakage or conduction.
Clamping Voltage	27.5–28 V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below absolute maximum ratings during surge.
Peak Pulse Current	40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems.
ESD Withstand	±30 kV contact & air (IEC 61000-4-2) - exceeds standard interface ESD requirements for rugged consumer and industrial ports.
Dynamic Resistance	20 mΩ - enables low-voltage-drop shunting, minimizing energy dissipation in the device and thermal stress.
Junction Capacitance	175 pF at 22 V, 1 MHz - low enough to avoid loading 22V power rails while maintaining effective transient suppression.

Pinout & Package

GS1679-INE3 is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads and UL 94V-0 molding compound. All pins must be soldered for rated surge performance.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A capability.
4, 5, 6	IN	Input connection to protected line (e.g., VBUS in USB Type-C); parallel connection ensures uniform current sharing and thermal distribution.

Key Features

Feature	Design Value
Constant-clamp architecture	Clamping voltage varies ≤0.5 V across 24–40A surge range - eliminates design margin inflation needed with traditional TVS diodes.
FET-based shunt topology	Uses low-R_DS(on) surge FET instead of PN-junction - reduces thermal runaway risk and improves reliability at high ambient temperatures.
Temperature-stable clamping	Clamps at ~27.6 V from −40°C to +125°C - enables single-part qualification across extended industrial temperature grades.
Low dynamic resistance	20 mΩ measured between 1A–40A (8/20μs) - minimizes IR drop and localized heating during multi-pulse surge events.

Applications

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, but marked with date code and reel packaging per Semtech ordering convention.	No functional difference; used interchangeably in production where tape-and-reel delivery is required.	Select TDS2211P.C for automated SMT assembly; GS1679-INE3 may reflect alternate branding or distribution channel marking.
uClamp2411ZA	24V working voltage, lower 24A IPP rating, 0.25pF capacitance - optimized for CC/SBU lines, not power rails.	Designed for low-capacitance data-line protection; unsuitable for 22V VBUS due to lower surge rating and higher clamping (~32V).	Use uClamp2411ZA only for sideband use (CC/SBU) in same USB-C designs; not a functional replacement for GS1679-INE3 on power paths.

Compared with TDS2211P.C, GS1679-INE3 shares identical protection performance and footprint but may differ in traceability or packaging format; compared with uClamp2411ZA, GS1679-INE3 provides 67% higher peak current handling and 4.5× lower clamping voltage on 22V rails - making it the sole suitable option for VBUS-level EOS defense.

FAQ

What is the maximum continuous operating voltage for GS1679-INE3?

The GS1679-INE3 has a reverse stand-off voltage (V_RWM) of 22 V, meaning it can continuously block up to 22 V DC without significant leakage or conduction. This makes GS1679-INE3 suitable for protecting 20V USB PD VBUS lines and other 22V-rated industrial power rails.

Does GS1679-INE3 meet IEC 61000-4-5 surge immunity standards?

Yes, GS1679-INE3 is rated for 40 A peak pulse current (8/20 μs) and withstands ±1 kV (1.2/50 μs voltage, 8/20 μs current, R_S = 42 Ω) per IEC 61000-4-5, satisfying Level 4 industrial surge requirements. Its stable clamping ensures compliance across temperature extremes.

How does GS1679-INE3 differ from standard TVS diodes in clamping behavior?

Unlike standard TVS diodes whose clamping voltage rises linearly with peak current (V_C = V_BR + I_PP × R_DYN), GS1679-INE3 uses a triggered FET to maintain clamping at 27.5–28 V from 24A to 40A - a key advantage for margin-critical 24V system designs.

What is the recommended PCB layout for optimal performance of GS1679-INE3?

Place GS1679-INE3 as close as possible to the protected connector. Connect all three IN pins (4,5,6) via a single short, wide trace to the protected line, and tie all three GND pins (1,2,3) directly to a solid ground plane using multiple vias - this minimizes parasitic inductance and preserves 40A surge capability.

Is GS1679-INE3 compatible with lead-free reflow processes?

Yes, GS1679-INE3 is Pb-free, halogen-free, and RoHS/WEEE compliant. Its DFN package supports standard JEDEC J-STD-020 moisture sensitivity level (MSL) 1 reflow profiles, including peak temperatures up to 260°C.
