Product details
Overview
VTVS10GSMF-HM3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection of low-voltage signal lines. It features 10.3 V maximum stand-off voltage (VRWM), 11.81–12.30 V reverse breakdown voltage (VBR) at 1 mA, ±2 % VBR tolerance, 23.98 A peak pulse current (IPPM), and 16.3 V maximum clamping voltage (VC) under 10/1000 μs waveform - deployed in automotive infotainment data lines.
For engineers reviewing the VTVS10GSMF-HM3-18 datasheet, VTVS10GSMF-HM3-18 pinout, VTVS10GSMF-HM3-18 application, or VTVS10GSMF-HM3-18 equivalent, key selection criteria include its ±2 % VBR tolerance, 16.3 V clamping performance at 23.98 A, IEC 61000-4-2 ±30 kV ESD immunity, AEC-Q101 qualification, and halogen-free SMF package compatibility with SOD-123W footprint.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its precisely specified breakdown range (11.81–12.30 V). Its low dynamic impedance ensures rapid clamping response (<1 ns), limiting transient energy to protected ICs during ESD events or inductive switching surges.
The SMF package enables high thermal dissipation (RthJL = 20 K/W) and supports wave/reflow soldering per J-STD-020 MSL level 1. With 175 °C max junction temperature and -55 °C to +175 °C operating range, it meets automotive under-hood and infotainment system reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform) - sustains high-energy transients without failure |
| Stand-off Voltage (VRWM) | 10.3 V - maximum continuous reverse voltage before leakage exceeds 0.05 μA |
| Breakdown Voltage (VBR) | 11.81–12.30 V at IT = 1 mA, ±2 % tolerance - tight regulation enables precise overvoltage threshold setting |
| Clamping Voltage (VC) | 16.3 V at IPPM = 23.98 A - limits downstream voltage stress during surge |
| ESD Immunity | ±30 kV contact & air discharge (IEC 61000-4-2) - protects against human-body-model ESD events |

Applications
| Automotive Infotainment Data Lines | USB 2.0 Interface Protection |
|---|---|
Use Scenario: Protecting HDMI, LVDS, or FPD-Link III video buses in head units and digital clusters from ESD and cable discharge events. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients while preserving DC bias and signal integrity. Use Value: 16.3 V clamping voltage prevents damage to SerDes receivers rated for ≤18 V absolute maximum, maintaining bit-error-rate compliance. |
Use Scenario: Safeguarding USB 2.0 D+ and D- lines in telematics control units against hot-plug ESD and connector arcing. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional placement on each line referenced to system ground provides targeted surge suppression. Use Value: 2095 pF capacitance at 0 V is low enough to avoid signal rise-time degradation on 480 Mbps USB 2.0 links. |
| Automotive CAN FD Transceiver Protection | Industrial Sensor Signal Conditioning |
Use Scenario: Shielding CAN FD physical layer transceivers (e.g., TCAN1042) from ISO 7637-2 pulse 1/2b surges and ESD in gateway modules. IC Role / Device Role / Timing Role: Placed across CAN_H–GND and CAN_L–GND to absorb common-mode transients without affecting differential signaling. Use Value: 10.3 V VRWM allows full operation across CAN FD's 2.2–3.6 V common-mode range while clamping >16 V threats. |
Use Scenario: Protecting 4–20 mA analog input channels in programmable logic controllers from field-wiring induced surges and lightning-induced coupling. IC Role / Device Role / Timing Role: Connected between signal line and loop ground to limit transient voltage seen by precision ADC front-end op-amps. Use Value: 175 °C max junction temperature supports operation in high-ambient industrial enclosures without derating. |
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 | ±5 % VBR tolerance (11.1–12.9 V), same 400 W rating, SMA package (DO-214AC) | Larger footprint (4.5 × 2.7 mm), higher RthJA, not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification or space constraints |
| TPSMF10A | ±5 % VBR, same SMF package, but no AEC-Q101 qualification and lower ESD rating (±25 kV) | Not validated for automotive use; suitable for consumer-grade industrial controls | Choose for non-automotive designs where footprint compatibility is critical but AEC-Q101 is unnecessary |
Compared with SMAJ10A and TPSMF10A, VTVS10GSMF-HM3-18 delivers tighter voltage tolerance, certified automotive reliability, and superior ESD robustness - making it the preferred choice for safety-critical or high-reliability signal-line protection where design margins and qualification traceability matter.

FAQ
What is the clamping voltage of the VTVS10GSMF-HM3-18 under standard test conditions?
The VTVS10GSMF-HM3-18 has a maximum reverse clamping voltage (VC) of 16.3 V when subjected to its rated peak pulse current of 23.98 A using the 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings.
Is the VTVS10GSMF-HM3-18 qualified for automotive applications?
Yes, the VTVS10GSMF-HM3-18 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life required for automotive electronic components. This qualification confirms its suitability for deployment in engine control units, infotainment systems, and ADAS modules where reliability under harsh environmental conditions is mandatory.
What does the "HM3-18" suffix in VTVS10GSMF-HM3-18 indicate?
The "HM3-18" suffix denotes halogen-free (H), RoHS-compliant and lead-free terminations (M), 3 k per 7″ reel packaging (3), and tape-and-reel orientation code -18 (cathode-up, standard carrier tape direction per Vishay specification). This packaging format supports automated SMT placement and aligns with automotive manufacturing traceability and environmental compliance requirements.
How does the ±2 % VBR tolerance of VTVS10GSMF-HM3-18 improve system protection compared to ±5 % variants?
The ±2 % VBR tolerance (11.81–12.30 V) of VTVS10GSMF-HM3-18 provides tighter control over the voltage threshold at which clamping initiates, minimizing the gap between stand-off voltage (10.3 V) and breakdown onset. This reduces the risk of premature conduction during normal operation while ensuring consistent, predictable protection timing - especially valuable in systems with narrow voltage margins like automotive CAN FD or USB 2.0 interfaces.
Can VTVS10GSMF-HM3-18 be used in bidirectional protection configurations?
No, VTVS10GSMF-HM3-18 is a unidirectional TVS diode and is not suitable for bidirectional protection. Its electrical characteristics - including polarity designation, single-anode/cathode structure, and asymmetric IV curve - are optimized for clamping positive transients relative to ground. For bidirectional applications such as AC lines or symmetric data buses, a dedicated bidirectional TVS (e.g., VTVS10B) or back-to-back diode configuration must be used instead of VTVS10GSMF-HM3-18.
