Product details
Overview
SHVM15 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), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance - deployed in USB PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the SHVM15 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternatives for 22V bus protection with constant-voltage suppression behavior.
Technical Context
The SHVM15 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 - 27.5–28V across 24–40A and −40°C to +125°C - due to decreasing RDS(on) under surge conditions.
It operates with 22V reverse stand-off voltage, 27.9V typical breakdown, <600nA leakage at 22V, and 175pF junction capacitance at 1MHz/22V - enabling robust protection without signal integrity compromise in high-speed or power-dense interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail derating margins. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - stays below 29V across full temp/current range, protecting 30V-tolerant controllers. |
| 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) - exceeds automotive and consumer ESD requirements without external staging. |
| Dynamic Resistance | 20mΩ - ensures minimal voltage rise under surge, enabling low-clamp performance independent of current magnitude. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with DC power rails and low-speed control lines; not intended for >100MHz data paths. |
| Package | DFN 1.6 × 1.6 × 0.55 mm, 6-lead - enables compact placement adjacent to connectors with minimal PCB area (<2.6 mm²). |
Pinout & Package
SHVM15 is housed in a RoHS-compliant, halogen-free DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed thermal pad (no solder paste required). All six terminals are surface-mount; pin 1 is marked with a laser dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three must be connected to maximize current handling and minimize inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS, load switch IN); tied together internally - requires single-point connection to protected bus trace. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across 24–40A and −40°C to +125°C - eliminates design margin inflation needed with TVS diodes. |
| FET-based shunt architecture | Surge-rated MOSFET + precision trigger circuit replaces pn-junction TVS - avoids thermal runaway and voltage drift with temperature. |
| Low dynamic resistance | 20mΩ - reduces IR drop during surge, enabling tighter clamping than TVS devices with fixed RDYN. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated surge events in industrial and metering applications. |
| Ultra-low leakage | <600nA at 22V - prevents standby power loss in battery-backed or always-on IoT nodes. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C ports supporting up to 20V/5A PD negotiation against ESD, lightning-induced surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping across temperature - avoids overvoltage damage to 30V-rated PD controllers where traditional TVS would exceed 35V at 125°C. |
Use Scenario: Safeguarding the input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and factory automation systems exposed to 42Ω/0.5μF surge coupling. IC Role / Device Role / Timing Role: Front-end transient diverter limiting voltage seen by the load switch's internal FET gate oxide and drain-source junction. Use Value: Clamps at ≤28V under 40A surge - stays below 30V damage threshold of common 30V-rated load switches, preventing latch-up or permanent failure. |
| IoT Device Power Rail Protection | Storage Device DC Power Interface |
Use Scenario: Securing 22V-rated auxiliary power inputs in edge-node gateways, smart sensors, and battery-charged peripherals subject to field ESD and induced surges. IC Role / Device Role / Timing Role: Standalone EOS protector on main DC input, upstream of PMIC or LDO regulators. Use Value: Delivers ±30kV ESD immunity and 40A surge capacity in <2.6 mm² footprint - enables ruggedized designs without discrete TVS arrays or PCB space penalties. |
Use Scenario: Protecting SATA or NVMe drive power connectors (e.g., +12V or +19V rails) against insertion transients, backplane coupling, and system-level ESD. IC Role / Device Role / Timing Role: Point-of-entry suppressor on storage subsystem power input, before bulk capacitance and regulation stages. Use Value: 175pF capacitance and 22V working voltage align with DC power integrity needs - avoids resonance or filtering issues common with high-capacitance TVS solutions. |
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 die, identical specs, Semtech-marked variant - functionally identical to SHVM15 per Semtech documentation and marking code cross-reference (T22 = 22V family). | Direct drop-in replacement with same DFN-6 footprint, pinout, and thermal profile. | Select when sourcing from Semtech-authorized channels requiring original part number traceability. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping, no constant-voltage behavior; 600W PPPK. | Higher clamping voltage increases risk of downstream IC damage at elevated temperatures or full surge current. | Choose only if cost sensitivity outweighs clamping performance and thermal stability requirements. |
Compared with TDS2211P and SMAJ22A, SHVM15 delivers identical constant-clamp performance and layout compatibility as TDS2211P but may differ in reel packaging or date-code marking; versus SMAJ22A, SHVM15 provides 9V lower clamping at rated current and stable voltage across temperature - critical for 30V-tolerant ICs in thermally demanding environments.

FAQ
What is the exact package type and dimensions of SHVM15?
SHVM15 uses a DFN package measuring 1.6 mm × 1.6 mm × 0.55 mm with 6 leads. Pin 1 is marked with a laser dot. The land pattern follows Semtech's recommended layout with three GND pins (1–3) and three IN pins (4–6), all requiring solid copper connections to maximize surge current capability and minimize parasitic inductance.
Does SHVM15 meet IEC 61000-4-5 surge immunity standards?
Yes, SHVM15 is rated for 40A peak pulse current using the 8/20μs waveform and ±1kV combination wave (1.2/50μs voltage + 8/20μs current, RS = 42Ω), satisfying IEC 61000-4-5 Level 4 requirements for industrial environments. Its 27.5–28V clamping ensures protected circuits remain within safe operating limits during such events.
How does SHVM15 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), SHVM15 uses a triggered FET shunt that maintains ~27.5–28V clamping from 24A to 40A and across −40°C to +125°C. This eliminates thermal derating and enables predictable protection for 30V-tolerant ICs without oversized margins.
Can SHVM15 be used on high-speed data lines like USB SuperSpeed?
No - SHVM15 is not suitable for high-speed data lines. With 175pF junction capacitance, it is intended for DC power rails or low-speed control signals. For USB SS, DP/DM, or PCIe lanes, Semtech recommends low-capacitance TVS devices like RClamp3371ZC (<0.25pF); SHVM15 should be placed only on VBUS, CC, or load switch input paths.
What is the maximum operating temperature range for SHVM15?
SHVM15 is specified for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage and leakage current remain stable across this full range, as confirmed by characterization data in the official datasheet - making it suitable for under-hood automotive modules, industrial drives, and outdoor IoT enclosures.
