Product details
Overview
S3HVM10 from Semtech is a transient diverting suppressor designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A (8/20μs) peak pulse current handling, and stable 27.5–28V clamping voltage across temperature and current range - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the S3HVM10 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping behavior vs. conventional TVS, and validated alternatives for 22V bus protection in high-reliability embedded and power delivery systems.
Technical Context
The S3HVM10 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 (27.5–28V) from 24A to 40A peak pulse current due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with <20mΩ dynamic resistance, 175pF junction capacitance at 22V/1MHz, and reverse leakage ≤600nA at VRWM = 22V - enabling robust protection without thermal derating penalties seen in junction-based TVS devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - supports nominal USB PD bus and industrial 24V rail inputs without DC blocking. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays within safe margin below typical 30V+ IC damage thresholds. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - eliminates need for secondary ESD stages in connector-facing designs. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for 22V power line use; not suitable for high-speed data lines. |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimal voltage overshoot during fast transients. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish.
| 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 sharing and minimize inductance. |
| 4, 5, 6 | IN | Protected line input - tied together to handle full 40A surge; requires direct routing from connector with minimal trace length. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables near-constant clamping voltage across 24–40A and –40°C to +125°C - avoids thermal runaway and derating issues of TVS diodes. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during surge, preserving clamping accuracy and reducing localized heating. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) supports repeated lightning-surge events in industrial and outdoor equipment. |
| Ultra-low leakage | ≤600nA at 22V enables use in always-on battery-backed systems without measurable standby drain. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Primary EOS suppression device placed immediately after the connector, before the PD controller and load switch. Use Value: Maintains 27.5–28V clamping across temperature - prevents false OVP trips and ensures reliable PD communication under ESD/lightning stress. |
Use Scenario: Safeguarding enable and input pins of high-side load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Transient shunt placed between VIN and GND to clamp surges before they reach the switch's internal FET gate or drain. Use Value: Prevents latch-up or permanent damage to load switch ICs by limiting voltage excursion to ≤28V during 40A transients. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
|
Use Scenario: Securing 22V auxiliary rails powering cellular modems or sensor hubs in battery-operated IoT gateways. IC Role / Device Role / Timing Role: Standalone transient suppressor on main DC input, operating continuously across wide ambient temperatures. Use Value: Delivers stable clamping without derating - critical for field-deployed units exposed to uncontrolled surge environments. |
Use Scenario: Protecting 22V backup power inputs in NVMe SSD enclosures and enterprise storage controllers. IC Role / Device Role / Timing Role: High-reliability surge guard on external 22V supply path, co-located with input capacitor. Use Value: Survives repeated 1kV/42Ω surges per IEC 61000-4-5 while maintaining low leakage (<600nA) to avoid backup battery discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same manufacturer, identical function and specs - confirmed drop-in replacement per Semtech documentation. | Identical pinout, footprint, and performance; used interchangeably in production designs. | Select TDS2211P when sourcing from Semtech-authorized channels with full traceability and lifecycle support. |
| SP1003-02HTG | TVS diode (not FET-based); higher clamping (~38V at 24A/125°C), 30% larger DFN-6 package (2.0×2.0mm). | Limited to lower-temperature or lower-current applications where clamping margin allows. | Choose SP1003-02HTG only if legacy design compatibility or dual-source strategy requires non-FET solution - expect higher clamping and thermal sensitivity. |
Compared with TDS2211P and SP1003-02HTG, the S3HVM10 offers identical FET-based clamping performance and footprint but is designated under Semtech's alternate part numbering scheme - ensuring same reliability, qualification, and manufacturing lot traceability as TDS2211P.

FAQ
What is the exact package type and dimensions of the S3HVM10?
The S3HVM10 uses a DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads. Pins 1–3 are ground terminals and pins 4–6 are input terminals - all must be soldered to maximize surge current capability. The land pattern matches Semtech's official DFN-6 outline drawing, and the device is RoHS-compliant with UL 94V-0 flammability rating.
How does the S3HVM10 differ from standard TVS diodes in clamping behavior?
The S3HVM10 uses a surge-rated FET and precision trigger circuit instead of a pn-junction, resulting in near-constant clamping voltage (27.5–28V) across its full 24–40A peak pulse current range and –40°C to +125°C operating temperature. In contrast, standard TVS diodes exhibit rising clamping voltage with both current and temperature due to fixed dynamic resistance.
Can the S3HVM10 be used on high-speed data lines like USB SuperSpeed or PCIe?
No - the S3HVM10 has 175pF junction capacitance at 22V, which is too high for signal integrity on high-speed differential pairs. It is intended exclusively for 22V power or low-frequency I/O lines. For USB SS, DP/DM, or CC/SBU lines, Semtech recommends low-capacitance devices like RClamp3371ZC or uClamp2411ZA alongside the S3HVM10.
What is the maximum continuous operating voltage for the S3HVM10?
The S3HVM10 has a reverse stand-off voltage (VRWM) of 22V, meaning it can safely operate with up to 22V DC applied continuously without leakage exceeding 600nA. Its reverse breakdown voltage (VBR) starts at 25V (min), confirming reliable blocking up to rated working voltage.
Is the S3HVM10 pin-compatible with the TDS2211P?
Yes - the S3HVM10 is a Semtech-authorized alternate marking for the TDS2211P. Both share identical DFN-6 package dimensions, pin configuration (pins 1–3 = GND, pins 4–6 = IN), electrical specifications, thermal characteristics, and qualification data. No PCB or schematic changes are required when substituting S3HVM10 for TDS2211P.
