Product details
Overview
S3HVM5 from Semtech is a transient diverting suppressor (TDS) 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 1.6×1.6×0.55mm 6-lead package - deployed in USB Type-C PD input protection.
For engineers reviewing the S3HVM5 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and current, low dynamic resistance for consistent surge handling, compatibility with 22V bus systems, and compact DFN layout suitability for space-constrained USB PD and industrial load switch interfaces.
Technical Context
The S3HVM5 implements a precision-triggered shunt FET architecture rather than conventional pn-junction TVS diodes, enabling near-constant clamping voltage over 24–40A pulse range and −40°C to +125°C operating temperature. Its trigger circuit activates the low-RDS(on) FET when transient voltage exceeds breakdown threshold.
Clamping is stabilized by the FET's decreasing on-resistance under increasing current, yielding VC ≈ VBR of the trigger circuit (27.5–28V), unlike linear VC = VBR + IPP × RDYN behavior in standard TVS devices. This eliminates thermal derating penalties seen in traditional solutions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.6V at 40A (8/20μs) - stays within safe margin below typical 30V+ damage thresholds of load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment. |

| Dynamic Resistance | 20mΩ - ensures minimal voltage rise during surge conduction, critical for low-voltage tolerance downstream ICs. |
| Junction Capacitance | 175pF at 22V - suitable for DC/low-frequency power line protection; not intended for high-speed data lines. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish, tape-and-reel packaging (3,000 pcs/reel).
| 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 parasitic inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS or power rail); parallel connection of all three pins ensures full 40A rating and uniform current distribution. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical electrical specs, pinout, and package - direct manufacturer-referenced variant of S3HVM5; same Semtech die and DFN construction. | Same USB PD, load switch, and industrial 22V rail use cases; documented in Semtech's official TDS2211P datasheet as functional match. | Select S3HVM5 for Aetrix inventory continuity; TDS2211P is alternate ordering code with identical performance and footprint. |
| uClamp2411ZA | 24V working voltage, lower 24A IPP rating, 30V clamping at 24A, smaller 0.6×0.6mm 2-pin DFN - lacks multi-pin parallel current sharing. | Targeted at CC/SBU lines in USB-C, not main VBUS; insufficient for 40A surge or 22V rail protection. | Not a functional replacement for S3HVM5 - use only for auxiliary signal-line protection where lower power and capacitance are prioritized. |
Compared with TDS2211P, S3HVM5 offers identical surge performance and layout compatibility, making it a seamless sourcing alternative; versus uClamp2411ZA, S3HVM5 delivers 67% higher peak current capability and 22V-specific clamping stability essential for power rail protection.

FAQ
What is the maximum operating temperature range for the S3HVM5?
The S3HVM5 operates reliably from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range due to the FET-based architecture - unlike standard TVS diodes whose clamping rises with temperature. This makes S3HVM5 especially suitable for industrial and automotive under-hood applications where thermal management is constrained.
Does the S3HVM5 require external bias or control signals to function?
No, the S3HVM5 is a fully passive, self-triggering device. It contains an integrated precision trigger circuit and surge-rated FET - no external power, enable pins, or configuration are needed. The S3HVM5 activates automatically when transient voltage exceeds its breakdown threshold, making it drop-in compatible with existing TVS layouts without redesigning control logic or power domains.
Can the S3HVM5 be used on high-speed data lines like USB SuperSpeed or PCIe?
No, the S3HVM5 is not suitable for high-speed data lines. With 175pF junction capacitance at 22V, it would severely degrade signal integrity on differential pairs operating above ~100MHz. The S3HVM5 is specifically designed for DC or low-frequency power and control lines - use low-capacitance devices like RClamp3371ZC (<0.25pF) for USB SS, DP/DM, or PCIe lanes instead.
How does the S3HVM5 compare to standard TVS diodes in terms of clamping voltage consistency?
The S3HVM5 maintains clamping voltage within 27.5–28V across 24–40A and −40°C to +125°C, whereas standard TVS diodes exhibit linear VC = VBR + IPP × RDYN rise - often exceeding 38V at 24A and 125°C. This consistency allows designers to confidently size downstream components without worst-case thermal derating margins, directly improving system robustness and BOM efficiency.
Is the S3HVM5 pin-compatible with other Semtech TDS devices like TDS2411P or TDS1211P?
No, the S3HVM5 is not pin-compatible with TDS2411P or TDS1211P. While all share the same 6-pin DFN 1.6×1.6mm package outline, their pin functions differ: S3HVM5 uses pins 1–3 as GND and 4–6 as IN, but TDS2411P and TDS1211P have distinct pin assignments per their respective datasheets. Always verify pin configuration using the official S3HVM5 documentation before PCB layout.
