Product details
Overview
VTVS8V5GSMF-M3-18 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 9.80 V to 10.20 V reverse breakdown voltage (VBR), 8.50 V maximum stand-off voltage (VRWM), 29.10 A peak pulse current (IPPM), 13.5 V clamping voltage (VC) at IPPM, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive infotainment power rails and USB Type-C port protection.
For engineers reviewing the VTVS8V5GSMF-M3-18 datasheet, VTVS8V5GSMF-M3-18 pinout, VTVS8V5GSMF-M3-18 application, or VTVS8V5GSMF-M3-18 equivalent, key selection criteria include its ±2 % VBR tolerance, 1270 pF typical junction capacitance at 0 V, 175 °C max junction temperature, low-profile SOD-123W-compatible footprint, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This TVS diode operates as a unidirectional clamping device, triggering into avalanche conduction when transient voltage exceeds its 9.80–10.20 V breakdown range. Its low-noise fast-response architecture achieves sub-nanosecond turn-on time, enabling effective suppression of ESD events and 10/1000 μs surges up to 400 W without latch-up or degradation.
The device uses silicon planar junction technology with halogen-free molding compound and is rated for -55 °C to +175 °C operation. Its thermal resistance (RthJL) is 20 K/W when mounted on an infinite heat sink, supporting robust thermal performance in high-density PCB layouts with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.80 V / 10.20 V - ensures precise overvoltage threshold activation with ±2 % tolerance for stable protection margin in 8.5 V systems. |
| VRWM | 8.50 V - maximum continuous reverse operating voltage; safely isolates protected line during normal 8.5 V DC operation. |
| IPPM | 29.10 A - peak pulse current handling capability under 10/1000 μs waveform, defining surge energy absorption limit. |
| VC @ IPPM | 13.5 V - clamping voltage during full-rated surge; limits downstream IC stress to safe levels below 15 V logic thresholds. |
| CD @ 0 V | 1270 pF - junction capacitance at zero bias; impacts signal integrity in high-speed interfaces like USB 2.0 or CAN FD. |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - meets highest industrial and automotive ESD immunity requirements. |
| TJ max | +175 °C - enables use in under-hood automotive environments and thermally constrained industrial 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 (8.08–8.92 V), 13.6 V VC, 28.7 A IPPM, SMA package (larger footprint) | Higher VC and looser VBR tolerance reduce protection margin in precision 8.5 V systems. | Select when cost sensitivity outweighs tight VBR control and board space permits SMA footprint. |
| TPSMD8.5A | ±5 % VBR (8.08–8.92 V), 13.4 V VC, 29.4 A IPPM, SMC package (3.9 × 2.5 mm) | Higher capacitance (1400 pF) and larger package may impact high-speed signal routing and PCB density. | Prefer where higher IPPM margin is prioritized and layout accommodates wider SMC outline. |
Compared with SMAJ8.5A and TPSMD8.5A, VTVS8V5GSMF-M3-18 delivers tighter ±2 % VBR control, lower 1270 pF capacitance, and smaller DO-219AB footprint - making it optimal for space-constrained automotive and USB applications requiring precise clamping and high ESD robustness.

FAQ
What is the exact reverse breakdown voltage range for VTVS8V5GSMF-M3-18?
The VTVS8V5GSMF-M3-18 has a guaranteed 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 tight specification ensures reliable triggering just above the 8.5 V stand-off voltage, minimizing false trips while maintaining adequate protection margin for 8.5 V nominal systems. The VTVS8V5GSMF-M3-18 datasheet confirms this range in Table 1 under "Electrical Characteristics".
Is VTVS8V5GSMF-M3-18 qualified for automotive applications?
Yes, VTVS8V5GSMF-M3-18 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life required for automotive electronic components. It supports operation from -55 °C to +175 °C and is commonly used in automotive infotainment, body control modules, and sensor interfaces. The VTVS8V5GSMF-M3-18 product family documentation explicitly lists AEC-Q101 qualification in the Ordering Information section.
What is the clamping voltage of VTVS8V5GSMF-M3-18 under full-rated surge conditions?
The VTVS8V5GSMF-M3-18 exhibits a maximum reverse clamping voltage (VC) of 13.5 V at its rated peak pulse current (IPPM) of 29.10 A, tested with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on the protected line during worst-case surge events, ensuring downstream ICs remain within their absolute maximum ratings. The VTVS8V5GSMF-M3-18 datasheet specifies this parameter in the Electrical Characteristics table.
Does VTVS8V5GSMF-M3-18 support lead-free reflow soldering?
Yes, VTVS8V5GSMF-M3-18 is fully compatible with lead-free reflow soldering processes, with a peak temperature rating of up to 260 °C per J-STD-020 MSL level 1 guidelines. Its halogen-free molding compound and tin-plated terminations meet RoHS and JEDEC standards. The VTVS8V5GSMF-M3-18 package data sheet confirms wave and reflow solderability as a core feature.
What is the junction capacitance of VTVS8V5GSMF-M3-18 at zero bias?
The VTVS8V5GSMF-M3-18 has a typical junction capacitance (CD) of 1270 pF measured at VR = 0 V and f = 1 MHz. This value directly affects high-frequency signal integrity in protected interfaces such as USB 2.0 or LIN bus lines. Because capacitance decreases with increasing reverse bias, actual dynamic capacitance during normal 8.5 V operation is significantly lower - a key factor confirmed in the VTVS8V5GSMF-M3-18 Typical Characteristics curves.
