Product details
Overview
VTVS23GSMF-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 signal lines. It features a ±2 % tolerance on avalanche breakdown voltage (26.51 V min / 27.60 V max at IT = 1 mA), 22.6 V maximum stand-off voltage, and clamps to ≤38 V at 10.40 A peak pulse current (10/1000 μs waveform), with 480 pF typical capacitance at 0 V.
For engineers reviewing the VTVS23GSMF-M3-08 datasheet, VTVS23GSMF-M3-08 pinout, VTVS23GSMF-M3-08 application, or VTVS23GSMF-M3-08 equivalent, this device is selected for high-reliability automotive infotainment interfaces, USB 2.0 data lines, and industrial sensor I/O where tight voltage tolerance, low clamping, and IEC 61000-4-2 ±30 kV ESD immunity are required.
Technical Context
This TVS diode operates as a unidirectional clamping device, triggered when reverse voltage exceeds its 22.6 V working threshold and avalanches at 26.51–27.60 V. Its low-profile SMF package enables placement near connectors or IC pins without compromising board space.
It delivers 400 W peak pulse power handling per IEC 61000-4-5 (10/1000 μs), maintains stable performance from −55 °C to +175 °C junction temperature, and achieves ±30 kV contact/air discharge ESD protection per IEC 61000-4-2 - verified under 10-pulse testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (supports IEC 61000-4-5 Level 4 surge events on 22.6 V lines) |
| Stand-off Voltage (VRWM) | 22.6 V (maximum continuous reverse voltage before leakage exceeds 0.05 μA) |
| Avalanche Breakdown (VBR) | 26.51–27.60 V at IT = 1 mA (±2 % tolerance ensures precise trigger consistency) |
| Clamping Voltage (VC) | ≤38 V at IPPM = 10.40 A (limits downstream voltage stress during transients) |
| Capacitance (CD) | 480 pF at VR = 0 V, f = 1 MHz (compatible with USB 2.0 and CAN FD signal integrity) |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2 compliant for front-panel and connector protection) |

IC Role / Device Role / Timing Role: Primary line-side TVS on differential bus lines, mounted adjacent to connector per IEC 61000-4-5 layout guidelines. Use Value: Maintains 22.6 V working margin while clamping 10.4 A surges to ≤38 V, preserving signal eye diagram integrity at 250 kbps. |
| USB 2.0 Host Port Protection | Automotive LIN Bus Node |
|

IC Role / Device Role / Timing Role: Dual-device configuration (one per line) with cathodes tied to data lines and anodes grounded. Use Value: 480 pF capacitance avoids USB 2.0 eye mask violations; ±30 kV ESD rating meets OEM port-level test requirements. |
Use Scenario: Protecting LIN transceivers (e.g., TJA1020) in door module ECUs from battery disconnect spikes and ESD during service. IC Role / Device Role / Timing Role: Single unidirectional TVS on LIN bus line, positioned between connector and transceiver input. Use Value: 22.6 V VRWM aligns with 12 V automotive supply derating; 175 °C TJ max supports under-dash mounting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | ±5 % VBR (25.6–28.2 V), 400 W, SMA package (DO-214AC), 550 pF | Higher capacitance and looser tolerance; less suitable for high-speed USB or tight-margin designs | Select when cost sensitivity outweighs precision clamping and board space is not constrained. |
| SMF24A | ±5 % VBR (25.6–28.2 V), 400 W, SMF package (same DO-219AB), 550 pF | Same footprint but ±5 % tolerance and higher capacitance reduces noise margin in 480 Mbps links | Use only if ±2 % tolerance and sub-500 pF are not required; verify layout compatibility with cathode marking orientation. |
Compared with VTVS23GSMF-M3-08, SMAJ24A and SMF24A offer identical power rating and package form factor but lack its ±2 % breakdown tolerance and lower 480 pF capacitance - making them viable alternatives only where tighter voltage control and high-speed signal fidelity are non-critical.

FAQ
What is the exact avalanche breakdown voltage range for VTVS23GSMF-M3-08?
The VTVS23GSMF-M3-08 has a reverse breakdown voltage (VBR) of 26.51 V minimum to 27.60 V maximum at IT = 1 mA and TJ = 25 °C, with ±2 % tolerance confirmed in Vishay's official datasheet revision 2.2. This tight tolerance ensures predictable triggering behavior across production lots and temperature ranges, critical for protecting sensitive 24 V nominal systems.
Is VTVS23GSMF-M3-08 RoHS-compliant and halogen-free?
Yes, VTVS23GSMF-M3-08 is RoHS-compliant and halogen-free, as explicitly stated in the Vishay datasheet (Document Number: 85891, Rev. 2.2). The SMF package uses halogen-free molding compound meeting UL 94 V-0 flammability rating, and termination plating is lead (Pb)-free tin, satisfying both EU RoHS Directive 2011/65/EU and JEDEC JS709C material requirements.
Does VTVS23GSMF-M3-08 meet AEC-Q101 qualification?
VTVS23GSMF-M3-08 itself is not marked as AEC-Q101 qualified in the base ordering code; however, Vishay offers AEC-Q101 qualified versions within the same VTVS23GSMF family (e.g., VTVS23GSMF-HM3-08). The -M3-08 suffix denotes tape-and-reel packaging (3K per 7″ reel) and standard environmental compliance - not automotive qualification. Always verify the full part number's qualification status via Vishay's official product page or distributor documentation.
What is the maximum clamping voltage of VTVS23GSMF-M3-08 under surge conditions?
The maximum reverse clamping voltage (VC) of VTVS23GSMF-M3-08 is 38 V at a peak pulse current (IPPM) of 10.40 A with a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and represents the upper limit of voltage seen by downstream circuitry during worst-case transient events - enabling reliable protection of 24 V logic interfaces and transceivers rated to 40 V absolute maximum.
Can VTVS23GSMF-M3-08 be used in bidirectional signal protection?
No, VTVS23GSMF-M3-08 is a unidirectional TVS diode and must be used only in circuits where polarity is fixed - such as protecting a single-ended signal referenced to ground. For bidirectional applications like RS-485 or CAN bus, a dedicated bidirectional TVS (e.g., VTVS23BGSMSF) or back-to-back unidirectional configuration is required. Using VTVS23GSMF-M3-08 in reverse-biased mode risks permanent damage due to lack of forward conduction rating.
