Product details
Overview
S2HVM15 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 peak pulse current (8/20μs), 27.6V clamping at 40A, 20mΩ dynamic resistance, and DFN 1.6×1.6mm package-used in USB Type-C PD bus protection.
For engineers reviewing the S2HVM15 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal stability data, functional pin mapping, real-world USB PD and load switch protection use cases, and two validated alternative parts with documented differences.
Technical Context
The S2HVM15 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 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with stable 27.5–28V clamping across temperature and current, and exhibits 175pF junction capacitance at 22V/1MHz-critical for minimizing signal distortion on protected lines while maintaining robust 1120W peak pulse power handling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.6V at 40A (8/20μs) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity standards without degradation. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough to avoid signal integrity issues on USB PD VBUS lines while enabling effective energy diversion. |
| Package | DFN 1.6×1.6×0.55mm, 6-lead - provides 60% board area reduction vs. SO-8 TVS solutions and supports high-density USB-C port layouts. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound, tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground connection for surge return path; all three pins must be connected to maximize current sharing and minimize parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., USB PD VBUS); parallel connection of all three pins ensures full 40A rating and uniform current distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V across 24–40A and −40°C to +125°C-enables reliable protection without derating at high temperature. |
| FET-based shunt topology | Replaces PN-junction TVS with low-RDS(on) MOSFET, eliminating linear VC = VBR + IPP×RDYN dependency and reducing thermal stress on junction. |
| High-energy surge handling | 1120W peak pulse power (8/20μs) supports repeated lightning-surge events in industrial equipment without parametric shift. |
| Low-leakage design | 600nA max reverse leakage at 22V ensures minimal standby power loss in battery-powered IoT devices. |
| USB-C optimized footprint | 1.6×1.6mm DFN matches layout constraints of modern USB Type-C connectors and enables co-location with RClamp3371ZC on superspeed lanes. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20V–22V USB PD VBUS lines against ESD, lightning-induced surges, and hot-plug transients in notebooks and docking stations. IC Role / Device Role / Timing Role: Primary EOS shunt protector placed directly at Type-C connector, clamping transients before they reach PD controller or load switch. Use Value: Maintains 27.6V clamping at 40A and 125°C-prevents overvoltage damage to 24V-rated controllers where standard TVS would exceed 38V at same conditions. | Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in remote meters and robotics against field-induced surges. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide and current-sense circuitry during EOS events. Use Value: Keeps clamping voltage below 28V across full temperature range-avoids gate oxide breakdown and false OVP triggering in e-fuse ICs. |
| IoT Device Power Rail Protection | Storage Device DC Power Input Protection |
Use Scenario: Securing 22V DC input rails in battery-backed smart sensors and edge gateways exposed to ESD during handling or installation. IC Role / Device Role / Timing Role: Standalone transient suppressor on main power entry point, coordinated with upstream fuse and downstream LDO. Use Value: Delivers ±30kV ESD immunity with only 175pF capacitance-preserves power-up timing and avoids LDO instability caused by high-capacitance TVS devices. | Use Scenario: Protecting SATA or NVMe SSD power inputs against surges induced by hot-swap events or shared chassis grounding in enterprise storage enclosures. IC Role / Device Role / Timing Role: High-power transient clamp on 12V/22V auxiliary rails feeding PMICs and flash controllers. Use Value: Handles 40A surge without thermal runaway-ensures sustained operation after multiple IEC 61000-4-5 events unlike thermally limited TVS diodes. |
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 electrical specs and package; S2HVM15 is Semtech's orderable part number for TDS2211P per official ordering info. | Direct replacement with identical pinout, marking, and performance; used interchangeably in BOMs. | Select S2HVM15 when sourcing from authorized Semtech distributors-identical to TDS2211P.C with 3,000/reel packaging. |
| uClamp2411ZA | 24V working voltage, lower 20A IPP rating, 30V clamping at 20A, 12pF capacitance-optimized for CC/SBU lines, not VBUS. | Intended for low-voltage, low-capacitance signal-line protection-not suitable for 22V power rail clamping. | Use uClamp2411ZA only for USB-C CC/SBU protection; S2HVM15 remains required for VBUS-level surge handling. |
Compared with TDS2211P (its direct identity) and uClamp2411ZA (a signal-line variant), S2HVM15 uniquely delivers 40A/22V power-rail protection with temperature-stable clamping-making it irreplaceable for USB PD VBUS and industrial load switch inputs where energy handling and voltage margin are critical.

FAQ
What is the exact relationship between S2HVM15 and TDS2211P?
S2HVM15 is Semtech's official orderable part number for the TDS2211P device, as confirmed in the "Ordering Information" section of the Rev 2.5 datasheet. Both share identical electrical specifications, pinout, package (DFN 1.6×1.6mm), marking ("T22"), and tape-and-reel packaging (3,000 units per 7-inch reel). No functional or parametric difference exists between S2HVM15 and TDS2211P.
Does S2HVM15 require external bias or control signals to operate?
No, S2HVM15 is a fully autonomous transient suppressor with no external control pins or bias requirements. It operates passively: the integrated trigger circuit detects overvoltage events on the IN pins (4–6) and activates the internal shunt FET within nanoseconds, diverting surge current to GND pins (1–3) without any external intervention or power supply.
Can S2HVM15 be used on high-speed data lines like USB SuperSpeed differential pairs?
No, S2HVM15 is not suitable for USB SuperSpeed (TX/RX) or DisplayPort lanes due to its 175pF junction capacitance, which would severely degrade signal integrity. For those lines, Semtech specifies low-capacitance TVS devices like RClamp3371ZC (<0.25pF). S2HVM15 is intended exclusively for VBUS, CC, SBU, or other low-frequency power/signal lines where capacitance is not critical.
What is the maximum ambient temperature at which S2HVM15 maintains its 40A surge rating?
S2HVM15 maintains its full 40A (8/20μs) peak pulse current rating across its entire operating temperature range of −40°C to +125°C, as validated in the "Peak Pulse Current vs. Temperature" graph (Figure 3, page 3 of datasheet). Unlike conventional TVS diodes, its FET-based architecture prevents thermal derating-no reduction in IPP is required at elevated temperatures.
How should PCB layout be optimized for S2HVM15 to achieve rated 40A performance?
To achieve full 40A surge capability, connect all three IN pins (4, 5, 6) via a single low-inductance trace to the protected line, and tie all three GND pins (1, 2, 3) directly to a solid ground plane using multiple vias. Place S2HVM15 within 5mm of the connector, avoid stubs or right-angle bends, and ensure symmetric routing-per Figure 7 in the datasheet-to minimize parasitic inductance that could elevate clamping voltage during fast transients.
