Product details
Overview
VTVS8V5GSMF-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 8.5 V maximum stand-off voltage (VRWM), 9.80–10.20 V reverse breakdown voltage (VBR) at 1 mA, 13.5 V maximum clamping voltage (VC) at 29.1 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity - used in automotive infotainment power rails and USB Type-C VBUS lines.
For engineers reviewing the VTVS8V5GSMF-HM3-08 datasheet, VTVS8V5GSMF-HM3-08 pinout, VTVS8V5GSMF-HM3-08 application, or VTVS8V5GSMF-HM3-08 equivalent, key selection criteria include its ±2 % VBR tolerance, halogen-free SOD-123W-compatible SMF package, 1270 pF typical junction capacitance at 0 V, 175 °C max junction temperature, and AEC-Q101 qualification status.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 9.80–10.20 V breakdown threshold, clamping transients to ≤13.5 V at 29.1 A (10/1000 μs waveform). Its low-noise fast-response architecture enables sub-nanosecond turn-on, critical for protecting sensitive 3.3 V/5 V logic interfaces.
The SMF package provides thermal resistance of 20 K/W (junction-to-lead, mounted on infinite heat sink) and supports wave/reflow soldering per J-STD-020 MSL level 1. It is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive under-hood and infotainment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform - sustains high-energy surges without failure) |
| Stand-off Voltage (VRWM) | 8.5 V (maximum continuous reverse operating voltage before conduction begins) |
| Breakdown Voltage (VBR) | 9.80–10.20 V at IT = 1 mA (±2 % tolerance ensures precise trigger point for 8.5 V systems) |
| Clamping Voltage (VC) | 13.5 V at IPPM = 29.1 A (limits downstream voltage stress during surge events) |
| Junction Capacitance (CD) | 1270 pF at VR = 0 V, f = 1 MHz (compatible with low-speed data/power lines; not suitable for >10 Mbps USB) |
| ESD Immunity | ±30 kV contact & air discharge (IEC 61000-4-2 - meets automotive and industrial ESD robustness requirements) |
| Operating Temperature | −55 °C to +175 °C (supports extended-range automotive and industrial environments) |
| Package | SMF (DO-219AB) - footprint compatible with SOD-123W, height 1.08 mm (low-profile PCB fit) |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; defines return path for clamped surge current |
| Cathode | Protected line input | Connected to line being protected (e.g., VBUS, CAN_H); conducts avalanche current to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VBR tolerance | Enables tighter system-level margin control vs. ±5 % variants - critical for 8.5 V rail protection where over-clamping risks IC damage |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock - suitable for front-end power modules |
| Halogen-free & RoHS-compliant | Meets automotive OEM environmental mandates (e.g., VW 80101, GMW3172) without compromising thermal or electrical performance |
| Low-profile SMF package | 1.08 mm height enables use in space-constrained modules (e.g., telematics ECUs, ADAS camera housings) without sacrificing 400 W surge rating |
| "Low-Noise" fast response | Sub-nanosecond turn-on time minimizes voltage overshoot during ESD events - protects 3.3 V/5 V microcontrollers and USB PHYs |
Applications
| Automotive Infotainment Power Rail | USB Type-C VBUS Protection |

| Industrial Sensor Interface Power | Smart Meter Battery Backup Line |
|
Use Scenario: Shielding 8.5 V auxiliary power rails for RS-485 transceivers and analog sensor front-ends from lightning-induced surges on long cables. IC Role / Device Role / Timing Role: Primary surge clamp on 24 V-to-8.5 V DC/DC output, activated before secondary crowbar circuits engage. Use Value: 400 W peak power rating handles 10/1000 μs surges up to 29.1 A - exceeds IEC 61000-4-5 Level 4 requirements. |
Use Scenario: Protecting lithium-thionyl chloride battery backup lines (nominal 8.5 V) in utility smart meters from ESD during field servicing. IC Role / Device Role / Timing Role: Low-leakage TVS (IR ≤ 0.1 μA at VRWM) placed across battery terminals to suppress handling-induced transients. Use Value: 0.1 μA max reverse leakage preserves battery shelf life (>15 years); −55 °C to +175 °C range accommodates outdoor meter enclosures. |
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 (8.1–8.9 V), 400 W, SMA package (2.7 mm height) | Higher profile limits use in ultra-thin modules; wider VBR tolerance reduces precision in 8.5 V systems | Select when cost sensitivity outweighs tight VBR control and board height constraints |
| TPSMD8.5A | ±5 % VBR, 400 W, DO-214AB package (2.3 mm height), no AEC-Q101 qualification | Lacks automotive qualification; 2000 pF capacitance may impair high-speed data lines | Prefer for industrial non-automotive designs where AEC-Q101 is not mandated |
Compared with SMAJ8.5A and TPSMD8.5A, VTVS8V5GSMF-HM3-08 offers tighter ±2 % VBR control, lower 1.08 mm profile, AEC-Q101 validation, and halogen-free construction - making it optimal for space-constrained, automotive-qualified 8.5 V rail protection where precision clamping and regulatory compliance are mandatory.

FAQ
What is the exact reverse breakdown voltage range for VTVS8V5GSMF-HM3-08?
The VTVS8V5GSMF-HM3-08 has a reverse breakdown voltage (VBR) of 9.80 V minimum to 10.20 V maximum at IT = 1 mA and TJ = 25 °C, with ±2 % tolerance confirmed in Vishay's Rev. 2.2 datasheet (Doc. #85891). This tight tolerance ensures consistent triggering behavior across production lots and temperature ranges, critical for protecting 8.5 V systems where overvoltage margin is narrow.
Is VTVS8V5GSMF-HM3-08 qualified for automotive applications?
Yes, VTVS8V5GSMF-HM3-08 is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section of the Vishay datasheet. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock - validating its suitability for under-hood and infotainment applications in passenger vehicles and commercial fleets.
What is the clamping voltage of VTVS8V5GSMF-HM3-08 at its rated peak pulse current?
The VTVS8V5GSMF-HM3-08 exhibits a maximum reverse clamping voltage (VC) of 13.5 V at IPPM = 29.1 A with a 10/1000 μs waveform. This value is measured per standard test conditions and guarantees that downstream circuitry sees no more than 13.5 V during worst-case surge events - essential for preserving the safe operating area of 12 V-rated regulators and interface ICs.
Does VTVS8V5GSMF-HM3-08 meet RoHS and halogen-free requirements?
Yes, VTVS8V5GSMF-HM3-08 is both RoHS-compliant and halogen-free, as documented in the "PACKAGE DATA" and "FEATURES" sections of the Vishay datasheet. The molding compound is UL 94 V-0 rated and conforms to Vishay's material categorization standard (Doc. #99912), satisfying stringent environmental mandates from automotive OEMs and industrial equipment manufacturers.
What is the junction capacitance of VTVS8V5GSMF-HM3-08, and how does it affect circuit design?
VTVS8V5GSMF-HM3-08 has a typical junction capacitance (CD) of 1270 pF at VR = 0 V and f = 1 MHz. This value is appropriate for DC power line and low-speed signal protection (e.g., USB 2.0, RS-485), but not recommended for high-speed interfaces like USB 3.0 or HDMI due to potential signal attenuation and impedance mismatch - designers must verify eye diagram integrity in target applications.
