Product details

Overview

GS12341-INTE3 from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy Electrical Overstress (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, 20mΩ dynamic resistance, and 175pF junction capacitance in a DFN 1.6×1.6×0.55mm 6-lead package. It is deployed in USB Type-C PD bus protection.

For engineers reviewing the GS12341-INTE3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and current, low dynamic resistance, DFN footprint compatibility, and compliance with IEC 61000-4-2/4-4/4-5 standards for industrial and portable electronics.

Technical Context

The GS12341-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 current and from –40°C to +125°C due to decreasing R_DS(on) under surge conditions.

It operates with a 22V reverse stand-off voltage (V_RWM) and 25–27.9V breakdown voltage (V_BR), features 130–600nA reverse leakage at 22V, and integrates three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3) to maximize surge current handling and minimize parasitic inductance.

Key Specifications

Parameter	Value and Actual Design Meaning
Reverse Stand-Off Voltage	22 V - Maximum continuous operating voltage before triggering
Clamping Voltage @ 40A	27.5–28 V - Limits transient voltage seen by protected ICs during 8/20μs surges
Peak Pulse Current	40 A (8/20μs) - Withstands high-energy lightning/surge events per IEC 61000-4-5
ESD Withstand	±30 kV contact & air - Meets highest IEC 61000-4-2 level for system-level ESD robustness
Dynamic Resistance	20 mΩ - Enables stable clamping by minimizing voltage rise under increasing current
Junction Capacitance	175 pF @ 22V, 1MHz - Low enough for 22V power rail protection without signal integrity impact

Pinout & Package

GS12341-INTE3 is housed in a Pb-free, RoHS-compliant DFN 1.6 mm × 1.6 mm × 0.55 mm 6-lead package with exposed thermal pad not required (energy dissipated in silicon). All pins must be connected: Pins 1–3 are tied to system ground; Pins 4–6 connect in parallel to the protected line.

Pin/Terminal	Circuit Role	Design Meaning
Pins 1, 2, 3	GND	Common ground return path for surge current; all three must be soldered to minimize inductance
Pins 4, 5, 6	IN	Parallel-connected input terminals for EOS/ESD protection of one 22V bus or line

Key Features

Feature	Design Value
Constant clamping voltage	27.5–28 V across 24–40A and –40°C to +125°C - eliminates derating uncertainty vs. standard TVS
Low dynamic resistance	20 mΩ - reduces voltage overshoot during fast-rising transients and improves energy handling
High EFT immunity	±4 kV per IEC 61000-4-4 (5/50 ns, 5 kHz & 100 kHz) - protects against repetitive burst noise in industrial settings
Small-footprint DFN	1.6 × 1.6 mm - saves >50% board area vs. SO-8 or SOT-23 TVS alternatives while maintaining 40A rating
Lead-free & Halogen-free	UL 94V-0 molding compound - meets global environmental compliance and safety requirements

Applications

USB Type-C Power Delivery Bus Protection	Industrial Load Switch Input Protection
Use Scenario: Protecting the V_Bus line in USB Type-C connectors supporting up to 20V PD operation against ESD, lightning surges, and connector hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed adjacent to the connector, clamping transients before they reach the PD controller or load switch. Use Value: Maintains 27.5–28V clamping at full 40A surge and across temperature-well below typical 30V+ damage thresholds of PD controllers.	Use Scenario: Safeguarding the input of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes exposed to field-installed wiring surges. IC Role / Device Role / Timing Role: Front-end transient suppressor that limits voltage stress on the load switch's internal FET gate oxide and drain-source junction. Use Value: Prevents premature failure of the load switch by holding clamping voltage <28V even at 125°C ambient-where conventional TVS clamping would exceed 35V.
Notebook/Tablet 22V Power Rail Protection	Storage Device DC Power Input Protection
Use Scenario: Securing the main 22V input rail of ultrabooks and tablets against ESD from docking stations, AC adapter transients, and battery insertion events. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV designs, placed directly at the DC jack or battery connector. Use Value: 175pF capacitance avoids power rail instability; ±30kV ESD rating exceeds IEC 61000-4-2 Level 4 system requirements.	Use Scenario: Protecting SATA or NVMe storage module power inputs in enterprise SSDs and NAS enclosures from backplane surges and hot-swap transients. IC Role / Device Role / Timing Role: High-reliability EOS guard for 22V auxiliary or main power rails feeding PMICs and flash controllers. Use Value: 1120W peak pulse power rating ensures survival of repeated 1.2/50μs ±1kV surges (IEC 61000-4-5) without parametric shift or degradation.

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	Same die, identical electrical specs, same DFN 1.6×1.6mm package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. GS12341-INTE3's unspecified reel count)	No functional difference; both rated for USB PD, industrial load switch, and 22V rail protection	Select TDS2211P.C when standard Semtech reel quantity and marking (T22 + date code) are required
uClamp2411ZA	24V V_RWM, lower 24A IPP rating, higher 30V clamping, smaller 0.6×0.3mm 2-pin DFN package	Better suited for CC/SBU lines in USB-C; insufficient for 40A V_Bus protection	Choose uClamp2411ZA only for low-current, low-capacitance auxiliary signal lines-not for main power rail protection

Compared with TDS2211P.C, GS12341-INTE3 shares identical protection performance but may differ in traceability or logistics labeling; versus uClamp2411ZA, GS12341-INTE3 provides 67% higher surge current capacity and 2.5V lower clamping-critical for safeguarding 22V power stages.

FAQ

What is the maximum continuous operating voltage for GS12341-INTE3?

The GS12341-INTE3 has a reverse stand-off voltage (V_RWM) of 22 V, meaning it can continuously block up to 22 V in normal operation without triggering. This makes it suitable for protecting 20V USB PD buses and other 22V-rated power rails where sustained voltage exposure occurs.

How does GS12341-INTE3 achieve stable clamping voltage across temperature?

GS12341-INTE3 uses a surge-rated FET architecture with a precision trigger circuit instead of a pn-junction diode. As surge current increases, the FET's R_DS(on) decreases, counteracting voltage rise-resulting in 27.5–28V clamping from –40°C to +125°C. This contrasts with TVS diodes whose clamping rises linearly with temperature.

Can GS12341-INTE3 replace standard TVS diodes in existing 22V designs?

Yes-GS12341-INTE3 is a drop-in replacement for many 22V TVS devices in terms of footprint (DFN 1.6×1.6mm) and voltage rating. However, its superior clamping stability and 40A rating may allow relaxation of downstream voltage margins. Always verify layout grounding (all GND pins connected) and placement near the protected connector.

What is the junction capacitance of GS12341-INTE3 and why does it matter?

The GS12341-INTE3 exhibits 175 pF junction capacitance at 22 V and 1 MHz. This value is optimized for 22V power rail protection-low enough to avoid destabilizing regulators or causing excessive ripple, yet higher than signal-line TVS devices (which target <1 pF), reflecting its power-focused design.

Does GS12341-INTE3 require a thermal pad on the PCB?

No. Unlike power MOSFETs or LDOs, GS12341-INTE3 dissipates surge energy within the silicon die itself and does not rely on PCB copper for thermal management. The datasheet explicitly states "no thermal pad is needed," and the DFN package lacks an exposed thermal slug-ground vias under Pins 1–3 suffice for low-inductance return.
