Product details
Overview
VTVS10ASMF-HM3-08 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, with 10.3 V maximum stand-off voltage, 11.4–12.7 V reverse breakdown voltage at 1 mA, and 16.3 V maximum clamping voltage at 23.2 A peak pulse current. It delivers ±30 kV ESD protection per IEC 61000-4-2 and operates from –55 °C to +175 °C, targeting automotive power line and USB interface surge suppression.
For engineers reviewing the VTVS10ASMF-HM3-08 datasheet, VTVS10ASMF-HM3-08 pinout, VTVS10ASMF-HM3-08 application, or VTVS10ASMF-HM3-08 equivalent, key selection criteria include its 10.3 V working voltage tolerance, 16.3 V clamping performance under 10/1000 μs transients, halogen-free SOD-123W-compatible SMF package, and AEC-Q101 qualification status.
Technical Context
This TVS diode uses silicon avalanche junction technology to provide fast-response overvoltage clamping for DC power rails and low-speed signal lines. Its unidirectional polarity enables integration into positive-rail protection schemes without reverse leakage concerns beyond 0.05 μA at VRWM.
The device achieves 400 W peak pulse power handling with a 10/1000 μs waveform and maintains thermal stability up to 175 °C junction temperature, supported by 20 K/W junction-to-lead thermal resistance when mounted on an infinite heat sink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 10.3 V - Maximum continuous reverse voltage before significant leakage; sets operating margin for 12 V nominal systems. |
| Breakdown Voltage (VBR) | 11.4–12.7 V at IT = 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system operating voltage. |
| Clamping Voltage (VC) | 16.3 V at IPPM = 23.2 A - Peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream ICs. |
| Peak Pulse Power (PPP) | 400 W - Sustained energy dissipation capability under standardized 10/1000 μs transient; validates robustness for ISO 7637-2 Pulse 1/2a/2b. |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - Full immunity to human-body-model surges without degradation. |
| Junction Temperature Range | –55 °C to +175 °C - Enables deployment in under-hood automotive, industrial motor control, and high-ambient environments. |
| Capacitance (CD) | 988 pF at VR = 0 V, f = 1 MHz - Low enough for <1 Mbps data lines (e.g., CAN, LIN), but not suitable for USB 2.0+ or HDMI. |
Pinout & Package
Package: SMF (DO-219AB), low-profile surface-mount case compatible with SOD-123W footprint; dimensions 3.9 mm × 1.9 mm × 1.08 mm; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; completes clamping loop during positive transients. |
| Cathode | Protected line input | Connected to line under protection (e.g., 12 V rail); conducts avalanche current to ground when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables compliance with ISO 7637-2 Level III and IEC 61000-4-5 (line surge) for automotive ECUs and industrial controllers. |
| ±5 % VBR tolerance (A-suffix) | Ensures predictable clamping threshold across production lots; supports tighter design margins than ±2 % G-suffix variants. |
| AEC-Q101 qualified (HM3 suffix) | Validated for automotive-grade reliability including HTOL, TC, and ESD stress; required for powertrain and body electronics. |
| Halogen-free, RoHS-compliant, lead-free terminations | Meets EU ELV and China RoHS requirements; supports environmentally aligned manufacturing and end-of-life recycling. |
| Wave and reflow solderable | Compatible with standard SMT assembly processes up to 260 °C peak temperature; eliminates need for special thermal profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same 10 V VRWM, but SMA package (DO-214AC); 400 W rating; ±5 % VBR; no AEC-Q101 qualification. | Larger footprint (4.5 × 2.7 mm vs. 3.9 × 1.9 mm); higher thermal resistance (50 K/W vs. 20 K/W); not automotive-qualified. | Select when cost sensitivity outweighs space constraints and automotive compliance is unnecessary. |
| VTVS10GSMF-HM3-08 | Identical package and ratings, but ±2 % VBR tolerance (932 type code); tighter breakdown window (11.81–12.30 V). | Better suited for designs requiring precise clamping threshold control, e.g., safety-critical monitoring circuits. | Choose when tighter VBR distribution justifies slightly higher unit cost and inventory complexity. |
Compared with SMAJ10A, VTVS10ASMF-HM3-08 offers 30 % smaller PCB area and superior thermal performance; versus VTVS10GSMF-HM3-08, it trades ±2 % VBR precision for broader process tolerance and lower cost-ideal for non-safety-critical 12 V rail protection.

FAQ
What is the maximum clamping voltage of VTVS10ASMF-HM3-08 under a 10/1000 μs surge?
The VTVS10ASMF-HM3-08 has a maximum reverse clamping voltage (VC) of 16.3 V at 23.2 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The VTVS10ASMF-HM3-08 maintains this clamping performance across its full operating temperature range.
Is VTVS10ASMF-HM3-08 qualified for automotive use?
Yes, VTVS10ASMF-HM3-08 is AEC-Q101 qualified, as confirmed by the "HM3" suffix in its ordering code. This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD robustness, making the VTVS10ASMF-HM3-08 suitable for automotive powertrain, chassis, and body electronics applications.
What does the "HM3" suffix mean in VTVS10ASMF-HM3-08?
The "HM3" suffix in VTVS10ASMF-HM3-08 indicates halogen-free, AEC-Q101 qualified, and 3 k per 7″ reel packaging. Specifically, "H" denotes halogen-free molding compound, "M" confirms AEC-Q101 qualification, and "3" specifies 3 k units per 7″ tape-and-reel. This distinguishes it from non-automotive variants like VTVS10ASMF-M3-08.
Can VTVS10ASMF-HM3-08 be used on high-speed data lines such as USB 2.0?
No, VTVS10ASMF-HM3-08 is not recommended for USB 2.0 or other >480 Mbps data lines due to its 988 pF typical junction capacitance at 0 V, which would severely degrade signal integrity. It is appropriate for lower-speed interfaces like CAN, LIN, RS-485, or power rails-but not high-speed differential signaling. For USB 2.0, consider low-capacitance TVS arrays instead of the VTVS10ASMF-HM3-08.
What is the thermal resistance of VTVS10ASMF-HM3-08, and how does it affect layout?
The VTVS10ASMF-HM3-08 has a junction-to-lead thermal resistance (RthJL) of 20 K/W when mounted on an infinite heat sink. In practice, this means effective PCB copper pour under the cathode/anode pads significantly improves power handling during repetitive surges. Layout should maximize thermal pad area and avoid narrow traces-especially critical for automotive applications where ambient temperatures exceed 105 °C. The VTVS10ASMF-HM3-08 benefits from symmetric thermal land patterns per Vishay's footprint recommendation.
