Product details
Overview
GS6042-INTE3Z from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and ultra-low 20mΩ dynamic resistance. It protects USB Type-C power delivery buses, load switch inputs, and industrial I/O interfaces.
For engineers reviewing the GS6042-INTE3Z datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and real-world implementation context for USB PD, IoT, and industrial equipment designs.
Technical Context
The GS6042-INTE3Z 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 across 0–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with stable 27.5–28V clamping at rated current, 175pF junction capacitance at 22V/1MHz, and <600nA reverse leakage. Its functional architecture decouples clamping performance from temperature drift-enabling reliable protection in thermally demanding environments like industrial controllers and USB PD chargers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage and ensures safe operation without leakage or false triggering during normal 20V operation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below typical 29V damage threshold of USB PD controllers, enabling robust overvoltage protection. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial and automotive-grade equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Class 4 ESD immunity, eliminating need for secondary ESD stages in portable electronics. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during surge conduction, minimizing power dissipation and thermal stress on the device. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with DC power rails and low-speed I/O; not suitable for >100MHz signal lines without additional filtering. |
Pinout & Package
GS6042-INTE3Z is housed in a RoHS-compliant, halogen-free DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no internal thermal pad required). All six terminals are surface-mount; pins 1–3 are tied to ground, pins 4–6 serve as protected input nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected with low-inductance routing to maximize 40A handling capability. |
| 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBUS); simultaneous connection ensures balanced current sharing and optimal clamping stability. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across full 0–40A surge range - eliminates design margin inflation needed with traditional TVS diodes. |
| Temperature-stable protection | Clamping remains 27.5–28V from −40°C to +125°C - removes thermal derating calculations for industrial and automotive applications. |
| Low dynamic resistance | 20mΩ measured between 1A–40A - reduces I²R heating and supports repeated surge events without degradation. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - sustains multi-event surge exposure in remote metering and factory automation systems. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V USB PD bus against lightning-induced surges and connector hot-plug transients in portable chargers and docking stations. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at Type-C receptacle, diverting >40A transients to GND before reaching PD controller IC. Use Value: Maintains 27.5V clamping at full 40A even at 125°C - prevents latch-up or gate oxide damage in downstream SiC/GaN PD controllers. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in robotics and remote meters exposed to field wiring surges. IC Role / Device Role / Timing Role: Front-end transient suppressor on VIN rail, limiting voltage seen by internal FET gate oxide during 1.2/50μs combo-wave events. Use Value: Keeps clamped voltage below 28V across temperature - avoids overvoltage failure of load switch's integrated OVP/UVLO comparators. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary power inputs in battery-backed smart sensors deployed in unshielded outdoor enclosures. IC Role / Device Role / Timing Role: Single-device solution for combined ESD, EFT, and surge protection on always-on supply lines feeding MCU and radio subsystems. Use Value: Delivers ±4kV EFT immunity (IEC 61000-4-4) and ±30kV ESD without degrading signal integrity - eliminates need for RC filters or cascaded protection. |
Use Scenario: Protecting 22V backup battery rails in NVMe SSDs and enterprise storage controllers subject to hot-swap and backplane coupling transients. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (<600nA) protector on standby power path, preserving battery life while blocking EOS. Use Value: Enables >10-year shelf life in storage modules by maintaining sub-μA quiescent current and stable clamping across wide temperature swings. |
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 code T22; GS6042-INTE3Z is Semtech's alternate ordering variant with identical die and test flow. | No functional difference; both qualified for USB PD and industrial use per same AEC-Q200-relevant stress testing. | Select GS6042-INTE3Z for availability through Aetrix Electronics' distribution channel; no redesign or validation required. |
| SMAJ22A | Standard unidirectional TVS diode; higher 38V clamping at 24A (125°C), 1.5Ω dynamic resistance, and significant temperature-dependent clamping rise. | Limited to lower-temperature consumer applications; unsuitable for sustained 125°C industrial operation where clamping exceeds 35V. | Only consider SMAJ22A if cost is primary constraint and thermal margin allows ≥10V headroom above protected IC's absolute max rating. |
Compared with TDS2211P.C, GS6042-INTE3Z offers identical protection performance with seamless supply-chain continuity; versus SMAJ22A, it delivers 10.5V lower clamping at full surge current and eliminates thermal derating-critical for compact, sealed industrial enclosures.

FAQ
What is the exact package type and dimensions of GS6042-INTE3Z?
GS6042-INTE3Z uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed copper pad. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern follows Semtech's recommended layout with multiple vias to ground plane for optimal surge current handling.
Does GS6042-INTE3Z require external components for basic operation?
No, GS6042-INTE3Z operates as a standalone protector with no external bias, resistors, or capacitors required. Its integrated trigger circuit and shunt FET enable immediate response to transients. However, PCB layout must minimize trace inductance-place GS6042-INTE3Z within 5mm of the protected connector and connect all GND pins directly to a solid ground plane.
How does GS6042-INTE3Z compare to standard TVS diodes in clamping performance?
Unlike standard TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), GS6042-INTE3Z maintains 27.5–28V clamping from 1A to 40A due to its FET-based architecture. At 125°C, its clamping stays flat while a typical 22V TVS exceeds 35V-making GS6042-INTE3Z essential for thermally constrained designs.
Can GS6042-INTE3Z protect high-speed data lines like USB SS or PCIe?
No, GS6042-INTE3Z is not suitable for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on >100MHz interfaces. It is intended exclusively for DC power rails and low-speed control lines (e.g., USB PD CC, load switch EN). For SuperSpeed lanes, use sub-0.3pF devices like RClamp3371ZC alongside GS6042-INTE3Z.
Is GS6042-INTE3Z compliant with RoHS, REACH, and halogen-free standards?
Yes, GS6042-INTE3Z is fully RoHS/WEEE compliant, lead-free, and halogen-free. Its molding compound meets UL 94V-0 flammability rating, and the lead finish is matte tin. Full compliance documentation-including material declarations and test reports-is available from Semtech upon request and supported by Aetrix Electronics' traceable sourcing program.
