Product details

Overview

GS1572-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), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance - enabling robust USB Type-C PD bus protection in industrial and portable electronics.

For engineers reviewing the GS1572-IBE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature (−40°C to +125°C), low 175pF junction capacitance at 22V, and DFN 1.6×1.6mm 6-lead package compatibility with high-density USB PD and load switch input layouts.

Technical Context

The GS1572-IBE3 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 (27.5–28V) across 24–40A IPP and −40°C to +125°C due to decreasing R_DS(on) under surge conditions.

It operates with reverse stand-off voltage (V_RWM) of 22V, breakdown voltage (V_BR) of 25–27.9V at 1mA, and reverse leakage <600nA at 22V. Its 1.2/50μs + 8/20μs combination waveform compliance (±1kV, R_S = 42Ω) supports industrial surge immunity standards for unsymmetrical lines.

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., USB PD controllers) remain below damage threshold during surge.
Peak Pulse Current	40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment interfaces.
ESD Withstand	±30kV contact & air (IEC 61000-4-2) - exceeds smartphone/tablet ESD requirements and enables connector-level protection without additional staging.
Junction Capacitance	175pF at 22V, 1MHz - low enough for USB PD V_BUS line protection without signal integrity degradation.
Dynamic Resistance	20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients.
Operating Temperature	−40°C to +125°C - supports operation in automotive cabin, industrial control, and outdoor IoT enclosures.

Pinout & Package

GS1572-IBE3 is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground connection - all three pins must be soldered to maximize surge current return path and minimize parasitic inductance.
4, 5, 6	IN	Protected line input - connects directly to V_BUS or power/data line; all three pins conduct surge current in parallel to achieve full 40A rating.

Key Features

Feature	Design Value
FET-based transient diversion	Replaces conventional TVS with active shunt architecture for stable clamping independent of IPP and temperature.
Constant clamping performance	27.5–28V across 24–40A and −40°C to +125°C - eliminates derating calculations required for standard TVS devices.
Low dynamic resistance	20mΩ - reduces voltage overshoot during sub-microsecond ESD events and improves energy handling efficiency.
High EFT immunity	±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive burst noise in motor drives and PLC environments.
Space-efficient packaging	1.6×1.6mm DFN footprint - saves >60% board area vs. SO-8 or SOT-23 TVS solutions rated for comparable surge energy.

Applications

USB Type-C Power Delivery Bus Protection	Industrial Load Switch Input Protection
Use Scenario: Protecting 20V–22V V_BUS lines in USB-C ports supporting up to 100W PD negotiation. IC Role / Device Role / Timing Role: Primary EOS suppressor placed between connector and PD controller or load switch, clamping surges before they reach sensitive silicon. Use Value: Maintains 27.5V clamping at 40A and 125°C - avoids overvoltage damage to 24V-rated PD controllers where conventional TVS would exceed 38V at same conditions.	Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) exposed to lightning-induced surges in remote meters or robotics. IC Role / Device Role / Timing Role: Front-end transient shunt that diverts >95% of 40A surge energy to ground before it stresses the load switch's internal FET. Use Value: Enables use of smaller, lower-cost load switches by preventing gate oxide rupture and thermal runaway during 1.2/50μs ±1kV transients.
IoT Edge Device Power Rail Protection	Notebook/Tablet V_BUS Line Protection
Use Scenario: Securing 22V-capable power inputs in battery-powered IoT gateways deployed in electrically noisy factory environments. IC Role / Device Role / Timing Role: Single-component solution for combined ESD, EFT, and surge immunity on main power rail, eliminating multi-stage protection networks. Use Value: Delivers ±30kV ESD, ±4kV EFT, and 40A surge capability in one 1.6×1.6mm device - reducing BOM count and PCB real estate by 3× vs. discrete TVS + MOV approaches.	Use Scenario: Protecting USB-C receptacle V_BUS lines in thin-profile notebooks and tablets where layout space and thermal constraints limit protection options. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-profile (0.55mm height) suppressor mounted adjacent to connector to minimize trace inductance. Use Value: Achieves full IEC 61000-4-2/4-4/4-5 compliance without compromising signal integrity or mechanical stack-up - critical for ultra-thin form factors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar transient suppression applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TDS2211P	Same die, identical electrical specs and package - GS1572-IBE3 is Semtech's alternate marking for TDS2211P per official ordering documentation.	Direct functional and physical replacement - validated for identical USB PD, load switch, and industrial use cases.	Select GS1572-IBE3 when sourcing through Aetrix Electronics' channel; identical performance and qualification to TDS2211P.C.
uClamp2411ZA	24V working voltage, 12A IPP, 30V clamping, SOD-323 package - lower surge rating and higher clamping than GS1572-IBE3.	Suitable only for CC/SBU lines or low-energy 24V rails; cannot replace GS1572-IBE3 on 22V V_BUS with 40A surge requirement.	Use uClamp2411ZA only for auxiliary signal lines; GS1572-IBE3 remains mandatory for primary power rail protection where 40A/28V clamping is required.

Compared with TDS2211P (identical part) and uClamp2411ZA (lower-energy alternative), GS1572-IBE3 provides the only DFN-packaged 22V suppressor with guaranteed 40A/28V clamping across industrial temperature range - making it irreplaceable for USB PD V_BUS and load switch front-end protection where surge margin and thermal stability are non-negotiable.

FAQ

What is the exact package type and dimensions of GS1572-IBE3?

GS1572-IBE3 uses a RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with six leads. Pin 1 is marked by a laser dot; pins 1–3 are GND, and pins 4–6 are the protected input node. The land pattern follows Semtech's recommended 1.45mm × 1.45mm copper pad layout with thermal vias.

Does GS1572-IBE3 meet IEC 61000-4-5 surge immunity requirements?

Yes, GS1572-IBE3 is rated for 40A peak pulse current (8/20μs) and ±1kV (1.2/50μs voltage, 8/20μs current, R_S = 42Ω) per IEC 61000-4-5 for unsymmetrical lines. Its 27.5–28V clamping ensures protected circuits remain within safe operating limits during Level 4 industrial surge events.

How does GS1572-IBE3 differ from standard TVS diodes in clamping behavior?

Unlike TVS diodes whose clamping voltage rises linearly with peak current (V_C = V_BR + I_PP × R_DYN), GS1572-IBE3 uses a triggered FET shunt that maintains ~27.5V clamping from 24A to 40A and across −40°C to +125°C - eliminating thermal derating and simplifying system-level surge margin analysis.

Can GS1572-IBE3 be used to protect USB Type-C CC and SBU lines?

No - GS1572-IBE3 is optimized for 22V power rail (V_BUS) protection and has 175pF capacitance, which is too high for CC/SBU signaling. For those lines, Semtech recommends uClamp2411ZA (0.5pF) or RClamp3371ZC (<0.25pF); GS1572-IBE3 should be reserved for V_BUS and high-current power paths.

What is the maximum continuous reverse stand-off voltage for GS1572-IBE3?

The reverse stand-off voltage (V_RWM) of GS1572-IBE3 is 22V - meaning it will not conduct significantly (<600nA leakage) under steady-state DC conditions up to this voltage. This matches nominal USB PD V_BUS levels (20V max) and provides 2V margin before breakdown at 25–27.9V.
