Product details

Overview

GS6151-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 27.6–28V clamping voltage across its full current and temperature range (−40°C to +125°C). It is deployed in USB Type-C PD input protection and industrial load switch front-end circuits.

For engineers reviewing the GS6151-INTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, low dynamic resistance (20 mΩ), junction capacitance (175 pF at 22V), and DFN 1.6×1.6mm 6-lead package compatibility with space-constrained USB and IoT designs.

Technical Context

The GS6151-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 - not linearly increasing - because the FET's R_DS(on) collapses under surge, minimizing voltage rise across current and temperature extremes.

It operates with a 22V reverse stand-off voltage (V_RWM), 25–27.9V breakdown (V_BR at 1mA), and exhibits only 130–600 nA leakage at V_RWM. Its 1.2/50μs + 8/20μs combination-wave clamping is specified at 2Ω source impedance, matching IEC 61000-4-5 Level 3/4 industrial surge requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
Working Voltage	22 V - defines maximum continuous DC bus voltage it safely blocks without leakage or conduction.
Clamping Voltage	27.6–28 V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surges.
Peak Pulse Current	40 A (8/20μs) - supports compliance with IEC 61000-4-5 ±1 kV (RS = 42 Ω) industrial surge testing.
ESD Withstand	±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity for handheld and connector-exposed interfaces.
Dynamic Resistance	20 mΩ - enables low-voltage drop under surge, critical for maintaining clamping stability across current range.
Junction Capacitance	175 pF at 22 V, 1 MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces.

Pinout & Package

GS6151-INTE3 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.

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

Key Features

Feature	Design Value
Constant-clamp architecture	Clamping voltage stays within 27.5–28 V from 24A to 40A surge - eliminates design margin inflation needed with traditional TVS devices.
Temperature-stable protection	Clamping remains flat from −40°C to +125°C - removes derating calculations required for conventional TVS diodes.
FET-based shunt topology	Uses low-R_DS(on) MOSFET instead of PN-junction - dissipates energy in channel rather than junction, improving reliability under repeated surges.
Low-leakage standby	Max 600 nA at 22 V - avoids loading sensitive 22V rails or battery-backed circuits during normal operation.

Applications

USB Type-C Power Delivery Protection	Industrial Load Switch Input Protection
Use Scenario: Protecting VBUS lines in USB Type-C ports supporting up to 20V/100W PD negotiation. IC Role / Device Role / Timing Role: Front-end transient suppressor placed between connector and PD controller or load switch. Use Value: Maintains 28 V clamping at 40A surge and 125°C ambient - prevents PD controller latch-up or gate oxide damage where standard TVS would exceed 35 V.	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: Primary EOS shunt device diverting transients before they reach the load switch's internal FET. Use Value: Limits voltage seen by load switch drain to ≤28 V - avoids overvoltage failure of integrated high-side FET rated for ≤30 V absolute max.

Use Scenario: Securing 22V auxiliary power inputs in battery-powered IoT gateways with cellular/Wi-Fi modules. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, upstream of PMIC or buck converter. Use Value: Delivers ±30 kV ESD robustness and 40A surge capacity in 1.6×1.6 mm footprint - enables compact, field-deployable enclosure designs without external heatsinking.	Use Scenario: Protecting 22V backup or auxiliary supply rails in NVMe SSD enclosures or enterprise storage backplanes. IC Role / Device Role / Timing Role: Point-of-load transient suppressor on 22V VDDQ or auxiliary bias rail. Use Value: 175 pF capacitance minimizes coupling into high-speed data lanes; stable clamping prevents false resets or NAND controller brownouts during hot-plug events.

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, and identical pinout - direct manufacturer-recommended variant with tape-and-reel packaging (3,000 pcs/reel).	Same use cases: USB PD, load switch, industrial 22V rail protection.	Select TDS2211P.C when sourcing from Semtech's official distribution channel with standard reel quantity and date-code traceability.
uClamp2411ZA	24V working voltage, lower 24A IPP rating, higher 33V clamping, and smaller 0.6×0.6mm 2-pin DFN package - optimized for CC/SBU lines, not power rails.	Intended for low-capacitance, low-current signal-line protection (e.g., USB-C CC pins), not 22V power bus protection.	Not suitable as functional replacement for GS6151-INTE3 due to lower surge rating, higher clamping, and incompatible pin count/function.

Compared with TDS2211P.C, GS6151-INTE3 shares identical protection performance and package but may differ in marking, reel labeling, or internal lot traceability; compared with uClamp2411ZA, GS6151-INTE3 provides 67% higher surge current capability and 5V lower clamping - making it the only viable option for 22V power rail EOS hardening.

FAQ

What is the exact package type and dimensions of GS6151-INTE3?

GS6151-INTE3 uses a DFN (Dual Flat No-lead) package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads. Pin 1 is marked with a laser dot; pins 1–3 are GND, and pins 4–6 are the IN terminal. The package is Pb-free, RoHS-compliant, and rated UL 94V-0 for flammability.

Does GS6151-INTE3 meet IEC 61000-4-5 surge immunity standards?

Yes, GS6151-INTE3 is rated for 40A peak pulse current (8/20μs waveform) and supports ±1 kV combination-wave surge testing per IEC 61000-4-5 with RS = 42 Ω and CS = 0.5 μF - meeting Level 3/4 industrial immunity requirements for 22V systems.

How does GS6151-INTE3 differ from standard TVS diodes in clamping behavior?

Unlike standard TVS diodes whose clamping voltage rises linearly with surge current (VC = VBR + IPP × RDYN), GS6151-INTE3 uses a triggered FET shunt that maintains near-constant clamping (27.6–28 V) from 24A to 40A and across −40°C to +125°C - eliminating thermal derating and current-margin uncertainty.

Can GS6151-INTE3 be used to protect USB Type-C CC lines?

No - GS6151-INTE3 is designed for 22V power rail protection (e.g., VBUS), not low-voltage signal lines. For CC/SBU protection, Semtech recommends uClamp2411ZA (24V, 2-pin, <0.5 pF), which offers lower capacitance and appropriate voltage rating for 5V-level signaling.

What is the maximum junction temperature and storage temperature range for GS6151-INTE3?

GS6151-INTE3 has a junction and storage temperature range of −55°C to +150°C, with an operating temperature range of −40°C to +125°C. Its clamping voltage and leakage current remain fully specified across this full operating range, as confirmed in the datasheet's typical characteristics plots.
