Product details
Overview
VTVS14GSMF-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 13.8 V maximum stand-off voltage (VRWM), 15.88–16.53 V reverse breakdown voltage (VBR) at 1 mA, 22.2 V maximum clamping voltage (VC) at 17.67 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity.
For engineers reviewing the VTVS14GSMF-HM3-08 datasheet, VTVS14GSMF-HM3-08 pinout, VTVS14GSMF-HM3-08 application, or VTVS14GSMF-HM3-08 equivalent, this device delivers precise overvoltage clamping with tight ±2 % VBR tolerance, halogen-free construction, AEC-Q101 qualification readiness, and compatibility with SOD-123W footprint for space-constrained PCB layouts.
Technical Context
This TVS diode operates in avalanche mode to clamp transient overvoltages above its breakdown threshold while maintaining low leakage (<0.05 μA at VRWM) and fast response time enabled by "Low-Noise" technology. Its unidirectional polarity supports DC-biased signal lines where reverse conduction must be blocked until clamping occurs.
The device sustains 400 W peak pulse power under 10/1000 μs waveform, achieves thermal resistance of 20 K/W to lead, and operates across -55 °C to +175 °C junction temperature range-enabling use in under-hood automotive and industrial environments where thermal robustness is critical.

|---|---|
|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine control units exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between signal line and ground to clamp transients before reaching MCU ADC input or CAN/LIN transceiver. Use Value: With 13.8 V VRWM and 22.2 V VC, it safeguards 12 V nominal systems without interfering with normal signal swing. |
Use Scenario: ESD protection on D+ and D- lines of USB 2.0 ports in infotainment head units and telematics modules. IC Role / Device Role / Timing Role: Low-capacitance (752 pF) unidirectional suppressor shunting ESD energy to ground while preserving 480 Mbps signal integrity. Use Value: ±30 kV IEC 61000-4-2 rating meets USB-IF compliance requirements without adding series impedance or timing skew. |
| HDMI Hot-Plug Detection Line | Industrial 24 V DC Input Stage |
|
Use Scenario: Protecting HPD (Hot-Plug Detect) line in HDMI source devices against user-induced ESD during cable insertion. IC Role / Device Role / Timing Role: Standoff voltage (13.8 V) exceeds HPD logic high (typically 3–5 V), ensuring no leakage or false triggering during normal operation. Use Value: Fast response and low clamping voltage prevent latch-up or damage to HDMI controller GPIO pins rated for 5.5 V max. |
Use Scenario: Secondary surge protection on 24 V auxiliary power inputs in PLC I/O modules subjected to IEC 61000-4-5 2 kV ring wave surges. IC Role / Device Role / Timing Role: Paired with upstream MOV or GDT to absorb residual energy after coarse clamping, handling repetitive 400 W pulses. Use Value: 175 °C TJ max and 20 K/W RthJL allow sustained operation in sealed 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 |
|---|---|---|---|
| SMAJ14A | ±5 % VBR tolerance (15.6–17.2 V), 400 W rating, SMA package (larger footprint) | Higher VBR spread increases risk of premature clamping in precision 12 V systems | Select when cost sensitivity outweighs tight voltage margin needs and board space permits SMA |
| TPSMD14A | ±5 % VBR, 400 W, DO-214AB package; 250 pF typical capacitance (vs. 752 pF) | Lower capacitance suits high-speed data lines but reduced ESD robustness (±25 kV) | Prefer for USB 3.0 or MIPI where <300 pF is mandatory; avoid for IEC 61000-4-2 Level 4 compliance |
Compared with SMAJ14A and TPSMD14A, VTVS14GSMF-HM3-08 offers superior voltage accuracy (±2 %), smaller SMF footprint, and guaranteed ±30 kV ESD performance-making it optimal for automotive and industrial designs requiring repeatable clamping behavior and compact layout.

FAQ
What is the clamping voltage of VTVS14GSMF-HM3-08 at its rated peak pulse current?
The VTVS14GSMF-HM3-08 has a maximum reverse clamping voltage (VC) of 22.2 V at 17.67 A peak pulse current (10/1000 μs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance is guaranteed across the full operating temperature range and supports reliable protection of 15 V-rated ICs.
Is VTVS14GSMF-HM3-08 qualified to AEC-Q101?
The VTVS14GSMF-HM3-08 carries the "H" environmental code indicating AEC-Q101 qualification readiness; however, final qualification status depends on the specific lot and ordering code configuration. Vishay documents AEC-Q101 testing for the VTVS14GSMF family, and the HM3-08 variant uses the same die and SMF package validated under that qualification. Always verify qualification status via Vishay's official product change notices or datasheet revision history.
What does the "HM3-08" suffix mean in VTVS14GSMF-HM3-08?
In VTVS14GSMF-HM3-08, "H" denotes AEC-Q101 qualification and halogen-free compliance, "M3" specifies tape-and-reel packaging with 3 k units per 7″ reel, and "-08" indicates RoHS-compliant, lead (Pb)-free terminations with tin plating. This full suffix confirms the part meets automotive-grade reliability, green manufacturing standards, and automated assembly requirements.
Can VTVS14GSMF-HM3-08 replace VTVS14ASMF-HM3-08 in existing designs?
Yes-VTVS14GSMF-HM3-08 can directly replace VTVS14ASMF-HM3-08 where tighter voltage tolerance is beneficial. Both share identical SMF package, pinout, VRWM (13.8 V), and VC (22.2 V), but VTVS14GSMF-HM3-08 offers ±2 % VBR (15.88–16.53 V) versus ±5 % for the "A" version (15.4–17.0 V). No PCB changes are required, though system-level validation is recommended to confirm improved margin utilization.
What is the thermal resistance of VTVS14GSMF-HM3-08, and how does it affect power dissipation?
The VTVS14GSMF-HM3-08 has a thermal resistance (RthJL) of 20 K/W from junction to lead when mounted on an infinite heat sink. This allows sustained 400 W pulse handling only for short durations (e.g., <1 ms), but enables reliable operation in repetitive surge scenarios when PCB copper area provides additional thermal path. For continuous power, derating curves in the Vishay datasheet (Doc. #85891) must be applied based on ambient temperature and layout.
