Product details
Overview
VTVS10GSMF-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. It features a 10.3 V maximum stand-off voltage (VRWM), 11.81–12.30 V reverse breakdown voltage (VBR) at 1 mA, and clamps to ≤16.3 V at 23.98 A peak pulse current (10/1000 μs), making it suitable for USB, HDMI, and automotive sensor interface protection.
For engineers reviewing the VTVS10GSMF-HM3-08 datasheet, VTVS10GSMF-HM3-08 pinout, VTVS10GSMF-HM3-08 application, or VTVS10GSMF-HM3-08 equivalent, key selection criteria include ±2 % VBR tolerance, IEC 61000-4-2 ±30 kV ESD immunity, 988 pF typical capacitance at 0 V, 175 °C max junction temperature, and halogen-free, AEC-Q101-qualified construction.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its precisely specified breakdown range (11.81–12.30 V). Its low-clamping behavior (VC ≤ 16.3 V at IPPM = 23.98 A) ensures protected ICs experience minimal overvoltage during 400 W transient events.
The SMF (DO-219AB) package enables high-power density with MSL level 1 moisture sensitivity and compatibility with standard reflow profiles (peak ≤260 °C). Its 988 pF capacitance and fast response support signal integrity in high-speed interfaces up to ~100 MHz.
Key Specifications

|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform); sustains automotive load-dump and industrial surge transients without failure |
| Stand-off Voltage (VRWM) | 10.3 V max; blocks normal operation voltage while remaining non-conductive below breakdown threshold |
| Breakdown Voltage (VBR) | 11.81–12.30 V at IT = 1 mA; ±2 % tolerance enables precise overvoltage trip point in safety-critical systems |
| Clamping Voltage (VC) | ≤16.3 V at IPPM = 23.98 A; limits downstream voltage stress to safe levels for 3.3 V/5 V logic and PHYs |

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), 400 W rating, SMA package (larger footprint, higher RthJA) | Less precise clamping threshold; not AEC-Q101 qualified; higher thermal resistance limits high-repetition surge duty | Select when cost sensitivity outweighs tight VBR control and automotive qualification requirements |
| VTVS10ASMF-HM3-08 | Same package and VRWM, but ±5 % VBR (11.4–12.7 V); otherwise identical electrical specs and construction | Acceptable for non-safety-critical industrial use where 0.5 V wider breakdown window is tolerable | Choose for general-purpose protection where ±2 % precision is unnecessary and BOM simplification is prioritized |
Compared with SMAJ10A and VTVS10ASMF-HM3-08, the VTVS10GSMF-HM3-08 delivers tighter voltage control and automotive qualification in the same compact SMF footprint-enabling higher system reliability in space-constrained, mission-critical designs without layout changes.

This tight tolerance ensures consistent clamping behavior across production lots and temperature extremes.
Is VTVS10GSMF-HM3-08 qualified for automotive applications?
Yes, VTVS10GSMF-HM3-08 is AEC-Q101 qualified, as explicitly stated in the Vishay ordering information table and environmental code "H" designation. It meets stress test requirements for temperature cycling, humidity bias, and mechanical shock applicable to automotive electronics deployed in engine bays and cabin modules.
What is the maximum clamping voltage of VTVS10GSMF-HM3-08 under surge conditions?
The VTVS10GSMF-HM3-08 clamps to a maximum of 16.3 V at 23.98 A peak pulse current (10/1000 μs waveform), per the Electrical Characteristics table in the official datasheet. This value represents worst-case reverse conduction during standardized surge testing and defines the upper voltage limit imposed on protected circuitry.
Does VTVS10GSMF-HM3-08 support automated PCB assembly processes?
Yes, VTVS10GSMF-HM3-08 is fully compatible with wave and reflow soldering per J-STD-020 MSL level 1 guidelines, with peak temperature rated at ≤260 °C. Its SMF (DO-219AB) package has documented footprint recommendations and tape-and-reel orientation (cathode bar facing unreeling direction), enabling seamless SMT integration.
How does the capacitance of VTVS10GSMF-HM3-08 affect high-speed signal lines?
VTVS10GSMF-HM3-08 exhibits 988 pF typical capacitance at VR = 0 V and f = 1 MHz, which is verified in the datasheet's Electrical Characteristics table. This value introduces negligible loading on USB 2.0 (480 Mbps) and CAN FD (5 Mbps) signals when placed with short traces, preserving signal rise time and eye opening without requiring impedance compensation.
