Product details
Overview
VTVS47GSMF-M3-08 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 46.8 V stand-off voltage, ±2 % breakdown voltage tolerance, 80 A peak pulse current (10/1000 μs), 80 V maximum clamping voltage, and 293 pF typical capacitance at 0 V.
For engineers reviewing the VTVS47GSMF-M3-08 datasheet, VTVS47GSMF-M3-08 pinout, VTVS47GSMF-M3-08 application, or VTVS47GSMF-M3-08 equivalent, key selection criteria include its tight 54.88–57.12 V reverse breakdown range, IEC 61000-4-2 ±30 kV contact/air discharge rating, AEC-Q101 qualification option, low-profile SOD-123W-compatible footprint, and halogen-free construction for automotive and industrial PCBs.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown triggered above its 46.8 V working voltage. Its 80 V clamping voltage at 80 A ensures robust protection for 48 V nominal systems while limiting stress on downstream ICs like CAN transceivers or microcontroller I/O pins.
The SMF package delivers thermal resistance of 20 K/W to an infinite heat sink and supports wave and reflow soldering per J-STD-020 MSL level 1. With a junction temperature range of –55 °C to +175 °C and ±30 kV ESD immunity, it meets stringent requirements for under-hood automotive and industrial control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 46.8 V - Maximum continuous reverse voltage before significant leakage; sets operating margin for 48 V rail protection. |
| Breakdown Voltage (VBR) | 54.88–57.12 V at IT = 1 mA - Tight ±2 % tolerance enables precise overvoltage threshold alignment without derating. |
| Clamping Voltage (VC) | 80 V at IPPM = 80 A (10/1000 μs) - Limits transient-induced voltage overshoot to safe levels for 5 V/3.3 V logic interfaces. |
| Peak Pulse Power (PPP) | 400 W - Sustains high-energy surges per ISO 7637-2 Pulse 1/2a/5a without degradation. |
| Capacitance (CD) | 293 pF at VR = 0 V, f = 1 MHz - Low enough for USB 2.0 and CAN FD signal integrity; avoids data distortion. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Eliminates need for secondary ESD stages in front-end protection circuits. |
| Operating Temperature | –55 °C to +175 °C - Supports placement near power converters or engine control units without thermal derating. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ47A-E3/57T | Same 47 V VRWM but ±5 % VBR tolerance; SMA package (larger footprint, higher RthJA). | Lacks AEC-Q101 qualification; lower ESD rating (±15 kV); not halogen-free. | Select when cost sensitivity outweighs precision clamping and automotive compliance. |
| TPSMD47A | 47 V VRWM, ±5 % VBR; 400 W rating; DO-214AB package; 1000 W peak for 1 ms. | Higher clamping voltage (84 V); larger 7.11 × 6.22 mm footprint; no AEC-Q101 option. | Choose for legacy board designs using SMA/DO-214AB land patterns where space allows. |
Compared with VTVS47GSMF-M3-08, SMAJ47A-E3/57T offers lower cost but sacrifices ±2 % precision and automotive qualification, while TPSMD47A trades compactness and ESD robustness for higher single-pulse energy handling in non-automotive industrial use.

FAQ
What is the exact reverse breakdown voltage range for VTVS47GSMF-M3-08?
The VTVS47GSMF-M3-08 has a reverse breakdown voltage (VBR) range of 54.88 V to 57.12 V at IT = 1 mA and TJ = 25 °C, reflecting its ±2 % tolerance designation ('G' suffix). This tight specification ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 48 V systems where overvoltage margins are narrow. The VTVS47GSMF-M3-08 maintains this range up to +125 °C junction temperature per Vishay's characterization data.
Is VTVS47GSMF-M3-08 AEC-Q101 qualified?
VTVS47GSMF-M3-08 is offered in an AEC-Q101 qualified version-denoted by the 'H' prefix in ordering codes such as VTVS47GSMF-HM3-08. The base part number VTVS47GSMF-M3-08 itself refers to the standard industrial-grade variant; qualification status must be confirmed by the full orderable part number. AEC-Q101 testing covers stress tests including HTGB, HTRB, and temperature cycling, validating reliability for automotive under-hood and cabin applications.
What is the thermal resistance and maximum junction temperature of VTVS47GSMF-M3-08?
VTVS47GSMF-M3-08 has a thermal resistance RthJL of 20 K/W when mounted on an infinite heat sink, and a maximum junction temperature (TJ) of +175 °C. Its SMF (DO-219AB) package enables efficient heat transfer through the leads, supporting sustained operation in high-ambient environments like engine control units or industrial motor drives. Derating curves in the Vishay datasheet confirm full 400 W pulse power capability up to +125 °C ambient when properly heatsinked.
How does the 293 pF capacitance of VTVS47GSMF-M3-08 affect high-speed signal lines?
The 293 pF typical capacitance of VTVS47GSMF-M3-08 at VR = 0 V and f = 1 MHz is optimized for DC and low-to-moderate speed interfaces-not high-speed serial links like USB 3.0 or PCIe. It is well-suited for USB 2.0 (480 Mbps), CAN FD (5 Mbps), and RS-485, where signal edge rates remain below ~100 MHz. For such applications, the VTVS47GSMF-M3-08 introduces negligible jitter or attenuation while delivering robust ±30 kV ESD protection.
What packaging and reel options are available for VTVS47GSMF-M3-08?
VTVS47GSMF-M3-08 is supplied in 8 mm tape on 7″ reels containing 3,000 units (MOQ = 30,000), and on 13″ reels holding 10,000 units (MOQ = 50,000). The 'M3' in the part number indicates moisture sensitivity level 1 (MSL-1) per J-STD-020, allowing unlimited floor life before reflow. Tape orientation follows standard SMF carrier configuration with cathode bar aligned toward the sprocket holes, as shown in Vishay document S8-V-3717.02-003.
