Product details
Overview
GV8500-CNE3 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 full current and temperature ranges. Used in USB Type-C PD bus protection, it replaces conventional TVS diodes where low, flat clamping voltage is critical to avoid damage to 20–22V-rated controllers.
For engineers reviewing the GV8500-CNE3 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 two validated alternative suppressors with documented clamping and thermal behavior differences.
Technical Context
The GV8500-CNE3 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 standard TVS diodes, its clamping voltage remains nearly constant - not linearly increasing - due to decreasing RDS(on) under surge conditions.
It operates over −40°C to +125°C, maintains ≤600nA reverse leakage at 22V, and exhibits only 20mΩ dynamic resistance (8/20μs). Its 175pF junction capacitance at 22V/1MHz supports moderate-speed power-line applications but excludes high-frequency data-line use without supplemental low-C protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 22 V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage (VC) | 27.5–28 V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures downstream 22V-rated ICs remain below absolute max stress limits during surge. |
| Peak Pulse Current (IPP) | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds USB IF and industrial ESD immunity mandates without derating. |
| Dynamic Resistance (RDYN) | 20 mΩ (8/20μs, 1–40A range) - enables flat clamping profile; <0.1Ω effective ON-resistance minimizes VC rise with current. |
| Junction Capacitance (CJ) | 175 pF at 22V, 1MHz - suitable for power rail or low-speed control line protection; not for USB SS or PCIe lanes. |
Pinout & Package
GV8500-CNE3 is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads and UL 94V-0 molding compound. The package features exposed thermal pad-less construction; energy dissipation occurs internally within the FET structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three pins must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBus or load switch input); parallel connection of all three pins required for full 40A rating and optimal clamping stability. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables near-constant clamping voltage across 1–40A surge range, unlike voltage-dependent TVS diodes. |
| Ultra-low dynamic resistance | 20 mΩ ensures minimal VC increase with rising IPP, critical for protecting tight-margin 22V power rails. |
| Stable clamping over temperature | Clamping remains 27.5–28 V from −40°C to +125°C - eliminates thermal derating calculations needed for TVS devices. |
| High-energy surge handling | 1120 W peak pulse power (8/20μs) supports repeated industrial lightning-surge events without degradation. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBus lines in USB-C PD ports against ESD, EFT, and 1.2/50μs surges during hot-plug or cable coupling events. IC Role / Device Role / Timing Role: Primary high-energy shunt suppressor placed directly at connector, clamping transients before they reach PD controller or buck converter. Use Value: Prevents latch-up or gate oxide damage in 22V-tolerant PD controllers (e.g., TUSB73x, STUSB4500) by holding clamping voltage ≤28V across full temperature and current range. |
Use Scenario: Safeguarding enable or input terminals of industrial-grade load switches (e.g., HS2950P, TPS229xx) subjected to lightning-induced surges in remote meters or robotics. IC Role / Device Role / Timing Role: Front-end transient diverter that routes surge current away from the load switch's internal FET drain-source path. Use Value: Keeps clamping voltage below the 30V absolute max rating of typical 22V-input load switches, preventing permanent ON-state failure or gate rupture. |
| IoT Edge Node Power Rail Protection | Notebook/Tablet Main Power Input Protection |
Use Scenario: Securing 19–22V DC input rails in battery-powered IoT gateways exposed to ESD during field servicing or surge-prone AC/DC adapter interfaces. IC Role / Device Role / Timing Role: Single-component EOS protector for compact, thermally constrained edge nodes where board space and thermal management are limited. Use Value: Delivers 40A surge capability in 2.56 mm² footprint - 60% smaller than equivalent SMA/SMB TVS solutions - with no thermal pad required. |
Use Scenario: Hardening 20V main power inputs (e.g., barrel jack or USB-C PD input) in thin-client notebooks and tablets against accidental 1kV/42Ω surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: High-reliability clamping device placed upstream of buck converters and battery charge management ICs. Use Value: Maintains consistent 28V clamping at 125°C ambient - avoids thermal runaway risk seen with TVS diodes whose VC rises >10% over temperature. |
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 (T22), same Semtech manufacturing lot traceability. | No functional or layout difference; direct form-fit-function match with identical thermal and surge performance. | Select when requiring Semtech's standard tape-and-reel packaging (3,000 pcs/reel) and official part number traceability. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP, higher 33V clamping, 12pF CJ; uses silicon avalanche diode, not FET-shunt architecture. | Better suited for CC/SBU lines in USB-C; insufficient for 40A VBus protection due to lower surge rating and rising VC with temperature. | Choose only for auxiliary signal lines where low capacitance is mandatory and surge energy is low; not a replacement for GV8500-CNE3 on power rails. |
Compared with TDS2211P.C, GV8500-CNE3 offers identical protection performance but may differ in reel packaging or date-code labeling; compared with uClamp2411ZA, GV8500-CNE3 provides 67% higher surge current, 19% lower clamping, and flat thermal response - making it the sole viable option for 22V power rail EOS hardening.

FAQ
What is the maximum continuous operating voltage for GV8500-CNE3?
The GV8500-CNE3 has a reverse stand-off voltage (VRWM) of 22 V, meaning it can continuously block up to 22 V DC or RMS without significant leakage or conduction. This makes it suitable for nominal 20V USB PD buses and 22V industrial power rails. Exceeding this voltage risks premature triggering or accelerated aging.
Does GV8500-CNE3 require a thermal pad on the PCB?
No, GV8500-CNE3 does not require a thermal pad. Its DFN-6 package dissipates surge energy internally via the FET structure, not through junction-to-board conduction. The datasheet explicitly states "no thermal pad is needed," and layout guidelines emphasize low-inductance GND vias instead of copper pour under the device.
How does GV8500-CNE3 clamping voltage behave at 125°C ambient?
GV8500-CNE3 maintains a clamping voltage of 27.5–28 V at 40A across −40°C to +125°C. Unlike TVS diodes whose VC increases >10% over temperature, GV8500-CNE3's FET-based architecture ensures stable clamping - confirmed by Figure 3 in the datasheet showing identical curves at −40°C, 25°C, and 125°C.
Can GV8500-CNE3 protect USB SuperSpeed (SS) differential pairs?
No, GV8500-CNE3 is not suitable for USB SuperSpeed lines. Its 175 pF junction capacitance would severely degrade signal integrity on 5–10 Gbps differential channels. For SS lane protection, Semtech recommends low-capacitance TVS devices like RClamp3371ZC (<0.25 pF), used alongside GV8500-CNE3 on the VBus line.
What is the recommended PCB layout for optimal surge performance with GV8500-CNE3?
Place GV8500-CNE3 as close as possible to the connector. Connect all three IN pins (4,5,6) via a single short, wide trace to the protected line, and tie all three GND pins (1,2,3) directly to a solid ground plane using ≥3 vias. Avoid stubs or splits - the goal is minimal loop inductance to preserve 40A surge capability and fast trigger response.
