Product details
Overview
VTVS8V5GSMF-HM3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, with 9.80 V to 10.20 V reverse breakdown voltage (VBR), 8.50 V maximum stand-off voltage (VRWM), and 29.10 A peak pulse current (IPPM) under 10/1000 μs waveform - deployed for ESD and surge protection on low-voltage DC power rails and I/O lines in automotive infotainment and industrial sensor interfaces.
For engineers reviewing the VTVS8V5GSMF-HM3-18 datasheet, VTVS8V5GSMF-HM3-18 pinout, VTVS8V5GSMF-HM3-18 application, or VTVS8V5GSMF-HM3-18 equivalent, key selection criteria include ±2 % VBR tolerance, 13.5 V clamping voltage at IPPM, 1270 pF junction capacitance, AEC-Q101 qualification status, and halogen-free SOD-123W-compatible SMF package with MSL level 1 rating.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its precisely specified 9.80–10.20 V breakdown range at IT = 1 mA. Its low-noise architecture delivers sub-nanosecond response time, enabling effective suppression of fast transients including IEC 61000-4-2 ±30 kV contact/air discharge events.
The VTVS8V5GSMF-HM3-18 is thermally rated for TJ = –55 °C to +175 °C and features RthJL = 20 K/W to lead, supporting high-reliability operation in engine bay and industrial control environments. Its 1.08 mm height and DO-219AB footprint ensure compatibility with space-constrained PCB layouts requiring wave or reflow soldering.
Key Specifications

|---|---|
| VBR (min/max) | 9.80 V / 10.20 V - tight ±2 % tolerance ensures predictable turn-on across temperature and production lots |
| VRWM | 8.50 V - maximum continuous reverse operating voltage before leakage exceeds 0.1 μA |
| IPPM | 29.10 A - peak surge current survivable under standardized 10/1000 μs waveform |
| VC @ IPPM | 13.5 V - clamping voltage limiting downstream circuit stress during full-rated surge |

Applications
| Automotive Infotainment Power Rail | Industrial RS-485 Interface |
|---|---|
Use Scenario: Protection of 8.5 V supply rail feeding LCD backlight drivers and audio amplifiers in head units. IC Role / Device Role / Timing Role: Unidirectional TVS clamp absorbing load dump and jump-start surges. Use Value: Limits rail voltage to ≤13.5 V during 29.1 A transients, preventing latch-up or burnout of downstream LDOs and Class D amplifiers. |
Use Scenario: ESD and surge protection on RS-485 differential pair (A/B) in factory automation PLC modules. IC Role / Device Role / Timing Role: Low-capacitance (1270 pF) unidirectional clamp placed between each line and ground. Use Value: Maintains signal integrity up to 10 Mbps while surviving ±30 kV contact discharge without degradation. |
| Automotive Body Control Module (BCM) | Medical Sensor Signal Conditioning |
Use Scenario: Input protection for LIN bus transceivers powered from 8.5 V local regulator. IC Role / Device Role / Timing Role: Standoff-clamp TVS suppressing coupled transients from adjacent solenoid drivers. Use Value: Prevents false LIN frame errors by clamping induced spikes within 1 ns, preserving bit timing margins. |
Use Scenario: Protection of analog front-end inputs (e.g., thermistor, strain gauge bridges) referenced to 8.5 V precision reference. IC Role / Device Role / Timing Role: Low-leakage (0.1 μA @ VRWM) unidirectional suppressor guarding against ESD during probe handling. Use Value: Avoids baseline shift or offset drift in µV-level measurements due to minimal reverse bias current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.5A | ±5 % VBR (8.06–8.94 V), 300 W PPPM, SMA package (larger footprint, higher RthJA) | Lower power rating and looser tolerance reduce margin in AEC-Q101-compliant 12 V systems | Select when cost sensitivity outweighs AEC-Q101 requirement and board space allows SMA footprint |
| TPSMD8.5A | ±5 % VBR, 400 W, but not AEC-Q101 qualified; 1500 pF CD; SMD package with 1.2 mm height | Higher capacitance degrades >5 Mbps serial links; lacks automotive qualification documentation | Acceptable for industrial non-automotive use where ESD robustness suffices and layout accommodates taller profile |
Compared with SMAJ8.5A and TPSMD8.5A, the VTVS8V5GSMF-HM3-18 provides tighter ±2 % VBR control, guaranteed AEC-Q101 compliance, and lower 1.08 mm profile-making it optimal for space-constrained, high-reliability automotive and industrial designs demanding precise clamping and long-term stability.

FAQ
What is the exact reverse breakdown voltage range for VTVS8V5GSMF-HM3-18?
The VTVS8V5GSMF-HM3-18 has a reverse breakdown voltage (VBR) range of 9.80 V to 10.20 V at IT = 1 mA and TJ = 25 °C, reflecting its ±2 % tolerance grade. This specification is verified per Vishay document 85891 Rev. 2.2 and applies directly to the VTVS8V5GSMF-HM3-18 part number without derating assumptions.
Is VTVS8V5GSMF-HM3-18 qualified to AEC-Q101?
Yes, VTVS8V5GSMF-HM3-18 is AEC-Q101 qualified - confirmed in Vishay's official documentation (Rev. 2.2, 19-Nov-2021) under the "Ordering Information" and "Features" sections. The "H" in the part number suffix denotes AEC-Q101 qualification, and test reports cover HTOL, temperature cycling, and mechanical shock per AEC-Q101 standards.
What does the "HM3-18" suffix mean in VTVS8V5GSMF-HM3-18?
In VTVS8V5GSMF-HM3-18, "H" indicates AEC-Q101 qualification, "M3" denotes halogen-free, lead (Pb)-free, tin-plated terminations, and "-18" specifies packaging on a 13" reel with 10,000 pieces per reel. This full suffix is defined in Vishay's ordering matrix on page 1 of document 85891.
Can VTVS8V5GSMF-HM3-18 be used in bidirectional configurations?
No, VTVS8V5GSMF-HM3-18 is a unidirectional TVS diode and must be used with cathode oriented toward the protected line's higher potential. Bidirectional protection requires either two devices in series opposition or a dedicated bidirectional part such as VTVS8V5BGMF-HM3-18 - which is not the same as VTVS8V5GSMF-HM3-18.
What is the thermal resistance from junction to lead (RthJL) for VTVS8V5GSMF-HM3-18?
The thermal resistance from junction to lead (RthJL) for VTVS8V5GSMF-HM3-18 is 20 K/W when mounted on an infinite heat sink, as specified in the "Absolute Maximum Ratings" table of Vishay document 85891. This value enables accurate thermal modeling for high-duty-cycle surge events in confined PCB areas.
