Product details
Overview
VTVS17GSMF-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 16.9 V maximum stand-off voltage (VRWM), 19.6–20.4 V reverse breakdown voltage (VBR) at 1 mA, 28 V maximum clamping voltage (VC) at 14.21 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive infotainment power rails and USB-C port protection.
For engineers reviewing the VTVS17GSMF-HM3-08 datasheet, VTVS17GSMF-HM3-08 pinout, VTVS17GSMF-HM3-08 application, or VTVS17GSMF-HM3-08 equivalent, key selection criteria include its ±2 % VBR tolerance, halogen-free SMF package with MSL level 1 rating, 175 °C junction temperature capability, and compatibility with wave/reef soldering processes for high-reliability automotive and industrial PCBs.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 19.6–20.4 V breakdown threshold to clamp transients within 1 ns response time. Its low-noise technology ensures minimal parasitic capacitance (606 pF at 0 V) while maintaining robust 400 W peak pulse power handling per 10/1000 μs waveform.
The SMF (DO-219AB) package provides thermal resistance of 20 K/W to leads on infinite heat sink, enabling reliable operation up to TJ = +175 °C. It is AEC-Q101 qualified and RoHS-compliant with tin-plated terminations, supporting automotive-grade production requirements without derating at elevated ambient temperatures.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VTVS17ASMF-HM3-08 | ±5 % VBR tolerance (19.0–21.0 V) vs. ±2 % for VTVS17GSMF-HM3-08 | Less precise clamping threshold; acceptable where 16.9 V rail has wider margin | Select when cost sensitivity outweighs need for tight VBR control in non-safety-critical designs |
| SMAJ17A-E3/5AT | Same VRWM (16.9 V), but 300 W PPPM (vs. 400 W); SMA package (DO-214AC), larger footprint | Lower surge rating and higher thermal resistance limit use in high-pulse-frequency environments | Choose only if legacy SMA layout exists and 400 W rating is not required for expected threat profile |

FAQ
What is the exact breakdown voltage range for VTVS17GSMF-HM3-08?
The VTVS17GSMF-HM3-08 has a reverse breakdown voltage (VBR) range of 19.6 V to 20.4 V at IT = 1 mA and TJ = 25 °C, reflecting its ±2 % tolerance grade. This tight specification ensures predictable clamping behavior in 16.9 V nominal systems, and the value is confirmed in Vishay's official datasheet revision 2.2 (Document Number: 85891). The VTVS17GSMF-HM3-08 maintains this tolerance across its full operating temperature range.
Is VTVS17GSMF-HM3-08 AEC-Q101 qualified?
Yes, VTVS17GSMF-HM3-08 is AEC-Q101 qualified, as explicitly stated in Vishay's datasheet under "FEATURES" and verified in the "ORDERING INFORMATION" table where "AEC-Q101 QUALIFIED" is marked for HM3 suffix variants. This qualification covers stress tests including HTGB, HTRB, and temperature cycling, confirming suitability for automotive powertrain and body electronics applications. The VTVS17GSMF-HM3-08 meets all requirements for Grade 1 (−40 °C to +125 °C ambient) operation.
What is the maximum clamping voltage of VTVS17GSMF-HM3-08 at rated peak pulse current?
The VTVS17GSMF-HM3-08 exhibits a maximum reverse clamping voltage (VC) of 28 V at its rated peak pulse current (IPPM) of 14.21 A, tested with a 10/1000 μs waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table of the Vishay datasheet and represents the worst-case voltage imposed on the protected line during a full-power transient event. The VTVS17GSMF-HM3-08 achieves this performance while maintaining low leakage (<0.05 μA at VRWM).
Does VTVS17GSMF-HM3-08 support lead-free reflow soldering?
Yes, VTVS17GSMF-HM3-08 supports lead-free reflow soldering with a peak temperature of up to 260 °C, as documented in the "PACKAGE DATA" section. Its terminations are tin-plated, and the SMF (DO-219AB) package is rated MSL level 1 per J-STD-020, allowing unlimited exposure to ambient conditions prior to assembly. The VTVS17GSMF-HM3-08 is fully compatible with standard IPC/JEDEC reflow profiles without pre-baking.
What is the capacitance of VTVS17GSMF-HM3-08 and how does it affect signal integrity?
The VTVS17GSMF-HM3-08 has a typical junction capacitance of 606 pF at VR = 0 V and f = 1 MHz. This value is measured and published in the "ELECTRICAL CHARACTERISTICS" table. While appropriate for DC power rail protection (e.g., USB-C VBUS, 12 V infotainment supplies), this capacitance limits use in high-speed data lines such as USB 3.2 or HDMI; the VTVS17GSMF-HM3-08 is intended for low-frequency or power-line applications where signal integrity is not compromised by sub-nF loading.
