Product details
Overview
VTVS9V4GSMF-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 DC lines such as USB, HDMI, and automotive sensor interfaces. It features 9.4 V maximum stand-off voltage (VRWM), 10.83–11.28 V reverse breakdown voltage (VBR) at 1 mA, and clamps to ≤14.9 V at 26.23 A peak pulse current (10/1000 μs).
For engineers reviewing the VTVS9V4GSMF-HM3-18 datasheet, VTVS9V4GSMF-HM3-18 pinout, VTVS9V4GSMF-HM3-18 application, or VTVS9V4GSMF-HM3-18 equivalent, this device delivers ±2 % VBR tolerance, ±30 kV IEC 61000-4-2 ESD immunity, halogen-free construction, and AEC-Q101 qualification - critical for automotive infotainment and ADAS interface protection.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, optimized for fast response (<1 ns) and low clamping ratio (VC/VBR ≈ 1.35). Its thermal resistance (RthJL = 20 K/W) and 175 °C max junction temperature support high-reliability operation in compact automotive PCB layouts.
The SMF package (DO-219AB) enables wave and reflow soldering, with MSL level 1 moisture sensitivity and UL 94 V-0 flammability rating. The cathode-bar marking and SOD-123W-compatible footprint simplify board-level integration without layout redesign.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VTVS9V4ASMF-HM3-18 | ±5 % VBR tolerance (10.5–11.6 V) vs. ±2 % for VTVS9V4GSMF-HM3-18 | Suitable for non-critical industrial controls where tighter voltage margin is not required | Select when cost sensitivity outweighs precision clamping needs |

FAQ
What is the clamping voltage of the VTVS9V4GSMF-HM3-18 at its rated peak pulse current?
The VTVS9V4GSMF-HM3-18 clamps to a maximum of 14.9 V at its rated peak pulse current of 26.23 A (10/1000 μs waveform). This value is measured per IEC 61000-4-5 and ensures protected circuits remain within safe operating limits during surge events. The VTVS9V4GSMF-HM3-18 achieves this with a clamping ratio of approximately 1.35 relative to its nominal breakdown voltage.
Is the VTVS9V4GSMF-HM3-18 qualified for automotive applications?
Yes, the VTVS9V4GSMF-HM3-18 is AEC-Q101 qualified and manufactured in accordance with automotive-grade process controls. It meets requirements for temperature cycling, humidity bias, and mechanical shock testing - making it suitable for engine bay, cabin, and ADAS subsystems. The VTVS9V4GSMF-HM3-18 also carries halogen-free and RoHS-compliant certifications required by major automotive OEMs.
What does the "HM3-18" suffix indicate in VTVS9V4GSMF-HM3-18?
The "HM3-18" suffix denotes three attributes: "H" indicates halogen-free construction, "M3" specifies lead (Pb)-free tin-plated terminations, and "-18" means packaging in 10,000-piece 13-inch reels (8 mm tape). This matches Vishay's standardized ordering code format defined in document 85891, ensuring consistent material and assembly compatibility across production lots of the VTVS9V4GSMF-HM3-18.
How does the VTVS9V4GSMF-HM3-18 compare to the VTVS9V4ASMF-HM3-18 in terms of voltage tolerance?
The VTVS9V4GSMF-HM3-18 has ±2 % tolerance on its reverse breakdown voltage (10.83–11.28 V), whereas the VTVS9V4ASMF-HM3-18 offers ±5 % (10.5–11.6 V). This tighter tolerance allows more precise system-level overvoltage margining and reduces risk of premature clamping or insufficient protection - a key differentiator for safety-critical automotive functions using the VTVS9V4GSMF-HM3-18.
Can the VTVS9V4GSMF-HM3-18 be used in bidirectional configurations?
No, the VTVS9V4GSMF-HM3-18 is a unidirectional TVS diode and must be oriented with cathode toward the protected line and anode to ground. For bidirectional protection, two VTVS9V4GSMF-HM3-18 devices may be connected in series opposing configuration, but Vishay does not specify or characterize that arrangement. Standard bidirectional alternatives (e.g., VTVS9V4B) are separate part numbers - the VTVS9V4GSMF-HM3-18 is not rated for reverse polarity operation.
