Product details
Overview
VTVS11GSMF-HM3-08 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 11.2 V maximum stand-off voltage (VRWM), 12.99–13.52 V reverse breakdown voltage (VBR) at 1 mA, and clamps to ≤18.0 V at 21.75 A peak pulse current (10/1000 μs).
For engineers reviewing the VTVS11GSMF-HM3-08 datasheet, VTVS11GSMF-HM3-08 pinout, VTVS11GSMF-HM3-08 application, or VTVS11GSMF-HM3-08 equivalent, key selection criteria include ±2 % VBR tolerance, IEC 61000-4-2 ±30 kV contact/air discharge compliance, 910 pF typical capacitance at 0 V, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a unidirectional avalanche diode with precise ±2 % breakdown voltage tolerance, enabling tighter system-level voltage margining in high-reliability applications. Its low-profile SMF (DO-219AB) package supports wave and reflow soldering, and its thermal resistance (RthJL = 20 K/W) allows effective power dissipation under transient stress.
The VTVS11GSMF-HM3-08 delivers fast response time via "Low-Noise" technology and achieves excellent clamping performance: VC ≤ 18.0 V at IPPM = 21.75 A (10/1000 μs), with forward clamping voltage VF = 1.8 V at IF = 50 A (1 ms). It is halogen-free, RoHS-compliant, and rated for TJ = −55 °C to +175 °C operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | ±5 % VBR tolerance (11.1–12.3 V), 400 W rating, SMA package (DO-214AC), RthJL = 35 K/W | Higher thermal resistance and looser voltage tolerance reduce precision in tight-margin 12 V systems | Select when cost sensitivity outweighs ±2 % VBR requirement and board space permits larger SMA footprint |
| 1.5SMC11A | ±5 % VBR, 1500 W rating, SMC package (DO-214AB), 2.4 mm height, 1.25 mm lead spacing | Higher power but larger size and non-AEC-Q101 qualification limit use in space-constrained automotive modules | Choose only for non-automotive industrial applications requiring >400 W surge handling and where PCB layout accommodates SMC outline |
Compared with SMAJ11A and 1.5SMC11A, the VTVS11GSMF-HM3-08 offers superior voltage accuracy, automotive qualification, and compactness-making it optimal for next-generation automotive electronics where footprint, thermal performance, and ESD robustness are co-constrained.

FAQ
What is the breakdown voltage tolerance of the VTVS11GSMF-HM3-08?
The VTVS11GSMF-HM3-08 has a ±2 % reverse breakdown voltage (VBR) tolerance, specified as 12.99 V minimum to 13.52 V maximum at IT = 1 mA and TJ = 25 °C. This tight tolerance enables accurate clamping threshold design in 12 V systems and reduces design margin overhead compared to ±5 % alternatives. The VTVS11GSMF-HM3-08 achieves this via laser-trimmed process control and is verified per Vishay Document 85891 Rev. 2.2.
Is the VTVS11GSMF-HM3-08 qualified for automotive applications?
Yes, the VTVS11GSMF-HM3-08 is AEC-Q101 qualified, meaning it has passed accelerated stress testing including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress testing (HAST) per the AEC-Q101 standard. This qualification confirms suitability for automotive under-hood and cabin electronics. The VTVS11GSMF-HM3-08 is explicitly listed in Vishay's qualified parts list for the eSMP® TransZorb® family.
What is the maximum clamping voltage of the VTVS11GSMF-HM3-08 under surge conditions?
The VTVS11GSMF-HM3-08 clamps to a maximum of 18.0 V at 21.75 A peak pulse current (10/1000 μs waveform), as specified in the Electrical Characteristics table of Vishay Document 85891. This clamping voltage ensures protected ICs-such as 12 V-tolerant transceivers or microcontrollers-remain within their absolute maximum ratings during transient events. The VTVS11GSMF-HM3-08 maintains this performance across its full operating temperature range.
Does the VTVS11GSMF-HM3-08 meet IEC 61000-4-2 ESD immunity standards?
Yes, the VTVS11GSMF-HM3-08 meets IEC 61000-4-2 with ±30 kV contact discharge and ±30 kV air discharge ratings, verified per the Absolute Maximum Ratings section of Vishay Document 85891. This level of ESD immunity makes the VTVS11GSMF-HM3-08 suitable for front-end protection of high-exposure interfaces such as USB ports, sensor harnesses, and CAN connectors in automotive and industrial equipment.
What is the package type and footprint compatibility of the VTVS11GSMF-HM3-08?
The VTVS11GSMF-HM3-08 uses the SMF (DO-219AB) package-a low-profile surface-mount outline measuring 3.9 × 1.9 × 1.08 mm-with cathode polarity marked by a bar. It is compatible with SOD-123W, SOD-123F, and SOD-123FL footprints and supports both wave and reflow soldering per J-STD-020 MSL level 1. The VTVS11GSMF-HM3-08's footprint recommendation is provided in Vishay's package drawing S8-V-3915.01-001.
