Product details
Overview
GS6151-INTE3Z 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. It is used in USB Type-C PD input protection where low, temperature-invariant clamping prevents damage to downstream controllers.
For engineers reviewing the GS6151-INTE3Z datasheet, pinout, applications, or equivalent options, this page provides verified electrical parameters, DFN-6 package layout guidance, real-world USB PD and load switch protection use cases, and validated alternative parts with documented functional differences.
Technical Context
The GS6151-INTE3Z 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 due to decreasing RDS(on) under surge conditions - not fixed dynamic resistance.
It operates across –40°C to +125°C with <20mΩ dynamic resistance and 175pF junction capacitance at 22V. Its 6-pin DFN package integrates three parallel input terminals (pins 4–6) and three ground terminals (pins 1–3), requiring full connection for rated 40A surge handling and minimal parasitic inductance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus voltage; ensures no leakage or conduction during normal operation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below 30V threshold of most 24V-rated USB PD controllers, preventing latch-up or gate oxide damage. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD immunity requirements without derating. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD ports. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for DC power rail protection; not suitable for high-speed data lines (requires separate low-C TVS). |
| Dynamic Resistance | 20mΩ - enables flat clamping curve; reduces voltage overshoot during fast-rising transients compared to TVS diodes. |
| Operating Temp | –40°C to +125°C - supports automotive-grade ambient environments and industrial enclosures without performance drift. |
Pinout & Package
GS6151-INTE3Z 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. All pins must be soldered per layout guidelines to achieve full 40A rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Low-inductance ground return path; all three must connect to solid ground plane via multiple vias for full surge current handling. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBUS); equal current sharing reduces thermal stress and improves reliability. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A surge - eliminates need for oversized margining in USB PD designs. |
| Temperature-stable protection | Clamping remains ~27.6V from –40°C to +125°C - avoids thermal runaway risk seen in standard TVS diodes. |
| Low dynamic resistance | 20mΩ enables sub-1V voltage rise under 40A surge - preserves safe operating area of protected load switches. |
| High-energy EOS handling | 1120W peak pulse power rating - sustains multi-millisecond surges common in industrial lightning-induced coupling. |
| DFN space efficiency | 1.6mm × 1.6mm footprint saves >60% board area vs. SOT-23 TVS solutions with comparable ratings. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS line in USB-C receptacles supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Primary EOS shunt device placed directly at connector, diverting surge energy before it reaches PD controller or buck converter. Use Value: Maintains 27.6V clamping at 125°C - prevents controller latch-up where conventional TVS would exceed 35V at same condition. |
Use Scenario: Safeguarding input of high-side load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Front-end transient suppressor limiting voltage across load switch FET drain-source during lightning-induced surges. Use Value: 20mΩ RDYN limits voltage overshoot to <1V above clamping level - keeps switch within SOA during 40A transients. |
| IoT Device DC Power Rail Protection | Notebook/Tablet VBUS Line Protection |
Use Scenario: Securing 12–24V DC input rails in battery-powered IoT gateways exposed to ESD during field servicing. IC Role / Device Role / Timing Role: Single-component solution replacing multi-diode TVS arrays, reducing BOM count and PCB area. Use Value: ±30kV ESD rating allows direct handling without gloves or wrist straps - simplifies manufacturing and repair workflows. |
Use Scenario: Protecting USB-C port VBUS on ultrabooks and tablets operating near thermal limits. IC Role / Device Role / Timing Role: Temperature-invariant clamping element ensuring consistent protection across chassis hotspots (e.g., near CPU/GPU). Use Value: Stable 27.6V clamping at +125°C junction temperature - avoids false trips or undervoltage lockout in thermally constrained layouts. |
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, DFN-6 package; differs only in tape-and-reel packaging (3,000 pcs/reel vs. GS6151-INTE3Z's unspecified quantity). | No functional difference; suitable for same USB PD, load switch, and industrial power rail roles. | Select TDS2211P.C when standard Semtech reel quantity and marking (T22 + date code) are required for traceability. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, higher 35V clamping at 20A, and 12pF capacitance - optimized for CC/SBU lines, not power rails. | Designed for low-capacitance data-line protection; unsuitable for VBUS due to insufficient surge rating and elevated clamping. | Choose uClamp2411ZA only for auxiliary signal lines (CC, SBU); avoid for power rail protection where GS6151-INTE3Z's 40A/28V capability is essential. |
Compared with TDS2211P.C, GS6151-INTE3Z offers identical protection performance but may differ in reel packaging and date-code marking; compared with uClamp2411ZA, GS6151-INTE3Z provides 2× higher surge current rating and 7V lower clamping - making it the sole viable option for 22V power rail EOS hardening.

FAQ
What is the exact package type and dimensions of GS6151-INTE3Z?
GS6151-INTE3Z uses a 6-lead DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed pad-less construction. Pin 1 is marked by a laser dot; land pattern follows Semtech's recommended outline with 0.30mm pitch and 0.50mm pad width. The package is Pb-free, halogen-free, and RoHS/WEEE compliant.
Does GS6151-INTE3Z require external bias or control signals to operate?
No, GS6151-INTE3Z is a fully passive, self-triggering device. It contains an integrated precision trigger circuit and surge-rated FET - no external voltage, enable pin, or configuration is needed. It activates automatically when input voltage exceeds breakdown threshold (~25V), making GS6151-INTE3Z ideal for "set-and-forget" protection in USB PD and industrial power systems.
Can GS6151-INTE3Z be used on high-speed data lines like USB SuperSpeed or DisplayPort?
No, GS6151-INTE3Z is not suitable for high-speed data lines. Its 175pF junction capacitance would severely degrade signal integrity on differential pairs operating above 100MHz. For USB SS, DP, or HDMI lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF); GS6151-INTE3Z is strictly intended for DC power or low-frequency I/O protection.
How does GS6151-INTE3Z compare to standard TVS diodes in clamping behavior under temperature variation?
Unlike standard TVS diodes whose clamping voltage rises linearly with temperature and peak current, GS6151-INTE3Z maintains ~27.6V clamping from –40°C to +125°C and across 24A–40A surge range. This stability stems from its FET-based architecture - where RDS(on) decreases under surge, counteracting thermal drift - a key advantage confirmed in GS6151-INTE3Z's published clamping vs. temperature curves.
Is GS6151-INTE3Z compatible with automated optical inspection (AOI) and solder paste inspection (SPI) processes?
Yes, GS6151-INTE3Z's DFN-6 package features clear top-side marking (T22 + date code) and uniform solderable terminations compatible with standard AOI and SPI systems. Its 0.55mm height and 1.6mm footprint meet IPC-7351B density Class B requirements, and the absence of thermal pad simplifies stencil design and reflow profiling for GS6151-INTE3Z placement.
