Product details
Overview
S2HVM5 from Semtech is a transient diverting suppressor IC designed for high-energy EOS protection on 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 across temperature and current range - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the S2HVM5 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 USB PD, IoT, and industrial equipment designs.
Technical Context
The S2HVM5 uses a surge-rated FET as its primary protection element, activated by an integrated 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 IPP 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, and reverse leakage under 600nA - 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 leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays flat across full rated current and temperature, limiting stress on downstream ICs. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 3 surge immunity for industrial equipment interfaces. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - eliminates need for secondary ESD stages in USB-C connector protection. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for DC power rails; not suitable for high-speed data lines (requires separate low-C TVS). |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during surge, minimizing energy dissipation in the device itself. |
| Package | DFN 1.6 × 1.6 × 0.55 mm, 6-lead - saves >50% board area vs. SO-8 TVS solutions while supporting high-current PCB routing. |
Pinout & Package
Package: DFN-6 (1.6 mm × 1.6 mm × 0.55 mm), Pb-free, RoHS-compliant, UL 94V-0 molding compound. Thermal pad not required - surge energy dissipated via FET channel, not junction heating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for all surge current paths; must be connected with low-inductance vias to internal ground plane. |
| 4, 5, 6 | IN | Parallel-connected input terminals for protected line (e.g., VBUS); all three pins must be routed together to maximize 40A capability. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A IPP - avoids overvoltage failure of USB PD controllers at elevated temperatures. |
| FET-based shunt topology | Surge energy diverted through low-RDS(on) channel instead of PN junction - eliminates thermal runaway and enables stable 125°C operation. |
| Multi-pin parallel input | Pins 4–6 electrically identical and internally bonded - reduces trace inductance and distributes current evenly for reliable 40A surge handling. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - ensures minimal voltage overshoot during fast-rising transients like ESD. |
| High-temp stability | Clamping voltage drift <±0.3V from –40°C to +125°C - removes need for derating curves in automotive or industrial thermal design. |
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 against lightning surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary high-energy shunt suppressor placed directly at connector, clamping transients before they reach PD controller or load switch. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents damage to HS2950P or similar load switches whose absolute max VIN is typically 28V. |
Use Scenario: Safeguarding input of industrial-grade e-fuses or load switches (e.g., in remote meters or robotics) exposed to 42Ω/0.5μF surge coupling per IEC 61000-4-5. IC Role / Device Role / Timing Role: First-line transient diverter upstream of current-limiting and OVP circuitry, absorbing >1kV common-mode surges. Use Value: Enables use of smaller, lower-cost load switches by holding clamped voltage below their gate oxide or drain-source breakdown limits under worst-case surge. |
| IoT Edge Node Power Rail Protection | Storage Device 24V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary power inputs in battery-backed IoT gateways subjected to EFT bursts (±4kV, 5/50ns) per IEC 61000-4-4. IC Role / Device Role / Timing Role: Solid-state EOS protector replacing Zener+SCR crowbar circuits, responding within nanoseconds to fast transients. Use Value: Delivers 4kV EFT immunity without latch-up or recovery delay - preserves system uptime where traditional SCRs require manual reset. |
Use Scenario: Shielding 24V backup supply inputs in NVMe SSD enclosures or RAID controllers from induced surges during AC mains switching events. IC Role / Device Role / Timing Role: High-power transient suppressor on primary DC input rail, coordinated with low-capacitance TVS on data lanes. Use Value: 1120W peak pulse power rating handles short-duration 24V rail surges without degradation - extends field life beyond polymer TVS alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping, no current-flat response. | Higher clamping voltage increases risk of downstream IC damage at 40A surges; requires larger derating margin above 85°C. | Lower cost but less robust for 40A/125°C industrial use - suitable only where peak current ≤15A and ambient <70°C. |
| TDS2211P | Same family, identical specs and package - direct functional match; Semtech's official replacement for S2HVM5 in new designs. | No application difference; validated in same USB-C and load switch reference designs. | Recommended for new designs requiring full documentation traceability and long-term supply assurance. |
Compared with SMAJ22A and TDS2211P, the S2HVM5 offers identical performance to TDS2211P (same die, marking variant) but differs from SMAJ22A by delivering 12V lower clamping at full 40A, eliminating thermal derating, and enabling compact 1.6mm² footprint - critical for space-constrained USB-C and IoT edge nodes.

FAQ
What is the exact clamping voltage specification for S2HVM5 at 40A surge current?
The S2HVM5 clamps at 27.5–28V under 40A (8/20μs) peak pulse current with 2Ω source impedance, per IEC 61000-4-5 combination waveform testing. This value is guaranteed across –40°C to +125°C and shows ≤0.5V variation from 24A to 40A - a key differentiator from TVS diodes whose clamping rises linearly with current. The S2HVM5 achieves this via its FET-based shunt architecture.
Is S2HVM5 pin-compatible with TDS2211P, and can it be used as a drop-in replacement?
Yes - S2HVM5 and TDS2211P share identical DFN-6 package dimensions (1.6 × 1.6 × 0.55 mm), pinout (Pins 1–3 = GND, Pins 4–6 = IN), electrical specifications, and thermal behavior. Semtech documents them as functionally equivalent variants; no PCB layout changes are needed when substituting S2HVM5 for TDS2211P in existing designs.
Does S2HVM5 require a thermal pad or heatsink for 40A surge handling?
No - the S2HVM5 dissipates surge energy through its low-RDS(on) FET channel rather than a PN junction, eliminating localized heating and thermal runaway. Its DFN package relies on PCB copper mass and multiple ground vias for heat spreading. Semtech explicitly states "no thermal pad is needed" in the datasheet, and layout guidelines emphasize low-inductance grounding over thermal relief.
Can S2HVM5 protect high-speed data lines such as USB SuperSpeed or PCIe?
No - the S2HVM5 has 175pF junction capacitance at 22V, making it unsuitable for data lines operating above ~10 Mbps. It is intended exclusively for DC power rails or low-frequency control signals. For USB SS, DP/DM, or CC lines, Semtech recommends pairing the S2HVM5 with low-capacitance TVS devices like RClamp3371ZC (<0.25pF) or uClamp2411ZA.
What is the maximum continuous reverse leakage current for S2HVM5 at 22V and 125°C?
At 22V reverse stand-off and +125°C, the S2HVM5 exhibits ≤600nA reverse leakage current - well within safe limits for 22V bus monitoring and low-power standby modes. This value is confirmed in the Electrical Characteristics table (IR max = 600nA at VRWM = 22V, T = 25°C), and typical curves show leakage remains <1μA even at 125°C.
