Product details

Overview

GS1672-IBE3 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 temperature and current range. Used in USB Type-C PD input protection to safeguard controllers from voltage overshoot.

For engineers reviewing the GS1672-IBE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under 40A surge, DFN-6 thermal and layout performance, 175pF junction capacitance at 22V, and compatibility with industrial and portable power bus protection requirements.

Technical Context

The GS1672-IBE3 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing R_DS(on) under increasing surge current - not fixed dynamic resistance.

It operates over –40°C to +125°C, maintains <20mΩ dynamic resistance (1A–40A, 8/20μs), and achieves stable 27.5–28V clamping at both 24A and 40A combination-wave surges (1.2/50μs voltage + 8/20μs current, R_S = 2Ω). Its 175pF capacitance at 22V and 1MHz enables use on moderate-speed power rails without signal integrity compromise.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction.
Clamping Voltage	27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - ensures downstream 24V-rated ICs (e.g., load switches, PD controllers) remain below damage threshold during surge.
Peak Pulse Current	40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirement for 22V systems.
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds USB Type-C and industrial interface ESD robustness requirements.
Junction Capacitance	175pF at 22V, 1MHz - low enough for 20V power rail protection without degrading transient response or causing excessive coupling.
Dynamic Resistance	20mΩ (8/20μs) - enables near-constant clamping by minimizing V = I × R contribution across full 1–40A surge range.
Reverse Leakage	600nA max at 22V - ensures negligible standby power loss and no measurable impact on 22V bus regulation.

Pinout & Package

GS1672-IBE3 is housed in a RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon).

Pin/Terminal	Circuit Role	Design Meaning
Pins 1, 2, 3	GND	Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A handling capability.
Pins 4, 5, 6	IN	Protected line input (e.g., VBUS, load switch input); parallel connection ensures uniform current sharing and optimal clamping performance.

Key Features

Feature	Design Value
FET-based transient shunt	Replaces conventional TVS with active switching - enables flat clamping curve independent of surge amplitude or temperature.
Stable clamping over temperature	27.5–28V clamping maintained from –40°C to +125°C - eliminates derating concerns in industrial or automotive under-hood environments.
Low dynamic resistance	20mΩ (1–40A, 8/20μs) - reduces voltage rise during surge, enabling tighter margin between clamping and IC absolute maximum ratings.
High-energy surge rating	1120W peak pulse power (8/20μs) - supports repeated lightning-surge events per IEC 61000-4-5 without degradation.
DFN-6 space efficiency	1.6mm × 1.6mm footprint - saves >50% board area vs. SOT-23 or SOIC alternatives while maintaining 6-terminal current distribution.

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), same tape-and-reel packaging (3,000/reel).	No functional difference - direct manufacturer-recommended alternate with identical qualification and traceability.	Select TDS2211P.C when sourcing from Semtech's official channel with full compliance documentation and lot traceability.
uClamp2411ZA	24V working voltage, lower 24A IPP rating, higher 30V clamping, smaller 0.65mm × 0.65mm DFN-2 package, 12pF capacitance.	Targeted at CC/SBU lines in USB-C, not VBUS - insufficient for 40A surge or 22V bus protection.	Use uClamp2411ZA only for low-capacitance data-line protection; not a functional substitute for GS1672-IBE3 in power-rail roles.

Compared with TDS2211P.C (identical spec) and uClamp2411ZA (lower surge rating, different application scope), GS1672-IBE3 provides verified 40A/22V power-rail protection in a production-qualified DFN-6 package - making it the optimal choice where high-energy EOS immunity and thermal stability are mandatory.

FAQ

What is the maximum continuous operating voltage for GS1672-IBE3?

The GS1672-IBE3 has a reverse stand-off voltage (V_RWM) of 22V, meaning it can continuously block up to 22V DC without significant leakage or conduction. This makes GS1672-IBE3 suitable for protecting 20V USB PD VBUS lines and other 22V-rated power rails where sustained voltage exposure occurs.

How does GS1672-IBE3 achieve stable clamping voltage across varying surge currents?

GS1672-IBE3 uses a surge-rated FET activated by a precision trigger circuit. As surge current increases, the FET's R_DS(on) decreases, counteracting the I×R voltage rise. This results in a nearly constant clamping voltage - 27.5–28V at both 24A and 40A - unlike conventional TVS diodes whose clamping rises linearly with current.

Can GS1672-IBE3 replace standard TVS diodes in 22V applications?

Yes - GS1672-IBE3 is specifically designed as a high-performance replacement for traditional TVS diodes in 22V systems. Its 40A surge rating, ±30kV ESD immunity, and temperature-stable clamping provide superior protection compared to PN-junction TVS devices, especially in industrial or automotive environments where thermal derating is a concern.

What is the recommended PCB layout for optimal performance of GS1672-IBE3?

Place GS1672-IBE3 as close as possible to the protected connector. Connect all three GND pins (1, 2, 3) directly to a solid ground plane using multiple vias, and tie all three IN pins (4, 5, 6) together with a short, wide trace. Avoid stubs or routing gaps - this minimizes parasitic inductance and ensures full 40A surge current handling capability.

Is GS1672-IBE3 compliant with RoHS and halogen-free standards?

Yes - GS1672-IBE3 is Pb-free, halogen-free, and fully compliant with RoHS and WEEE directives. Its molding compound meets UL 94V-0 flammability rating, and lead finish is lead-free, satisfying environmental and safety requirements for global industrial and consumer electronics manufacturing.
