Product details
Overview
VTVS23GSMF-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 22.6 V stand-off voltage (VRWM), 26.51–27.60 V reverse breakdown (VBR at IT = 1 mA), 38 A peak pulse current (IPPM), 38 V clamping voltage (VC), and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive infotainment power rails and USB-C port protection.
For engineers reviewing the VTVS23GSMF-M3-18 datasheet, VTVS23GSMF-M3-18 pinout, VTVS23GSMF-M3-18 application, or VTVS23GSMF-M3-18 equivalent, key selection criteria include its ±2 % VBR tolerance, 480 pF junction capacitance at 0 V, 175 °C max junction temperature, SOD-123W-compatible low-profile SMF package, and AEC-Q101 qualification status for automotive use.
Technical Context
This device operates as a unidirectional avalanche diode with precise 22.6 V working voltage threshold, enabling reliable overvoltage clamping before downstream ICs sustain damage. Its 10/1000 μs waveform-rated 400 W peak pulse power and 38 V clamping at 38 A ensure robust transient suppression without latch-up or thermal runaway.
The SMF package delivers MSL level 1 moisture sensitivity, 1.08 mm height, and wave/reflow solder compatibility - optimized for space-constrained PCB layouts in automotive and industrial control modules where board real estate and thermal management are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 22.6 V - maximum continuous reverse voltage before significant leakage; sets operating margin for 24 V nominal systems. |
| Breakdown Voltage (VBR) | 26.51–27.60 V at IT = 1 mA, ±2 % tolerance - tight regulation enables predictable clamping onset in safety-critical circuits. |
| Clamping Voltage (VC) | 38 V at IPPM = 38 A - limits transient voltage seen by protected ICs to safe levels during 10/1000 μs surges. |
| Junction Capacitance (CD) | 480 pF at VR = 0 V, f = 1 MHz - impacts high-speed signal integrity; suitable for <10 Mbps data lines like CAN FD or RS-485. |
| ESD Rating | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 immunity requirements for automotive and industrial interfaces. |
| Package | SMF (DO-219AB), SOD-123W-compatible - 3.9 × 1.9 × 1.08 mm footprint supports automated assembly and thermal dissipation via PCB copper. |
| Operating Temperature | −55 °C to +175 °C - qualified for under-hood automotive environments and industrial motor drive control units. |
Pinout & Package
SMF (DO-219AB) package: low-profile surface-mount case with cathode marking bar; compatible with SOD-123W, SOD-123F, and SOD-123FL footprints. Dimensions: 3.9 mm length × 1.9 mm width × 1.08 mm height; recommended land pattern includes 1.3 mm pad width and 2.9 mm pad length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during forward conduction; tied to protected line ground or low-side return path | Provides low-impedance discharge path to ground when clamping transients on positive rail. |
| Cathode | Current exit during reverse-biased clamping; connected to protected signal/power line | Acts as the input node for overvoltage events - must be placed directly at IC pin or connector entry point. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables single-device protection against ISO 7637-2 Pulse 1/2a/5a surges in 24 V automotive systems without external series impedance. |
| ±2 % VBR tolerance (G-series) | Reduces design margin uncertainty vs. ±5 % A-series parts, allowing tighter system-level voltage window definition. |
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - supports PPAP documentation and OEM sourcing mandates. |
| "Low-Noise" fast response | Sub-nanosecond turn-on ensures clamping occurs before sensitive logic or analog circuitry experiences overvoltage stress. |

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-E3/5AT | ±5 % VBR tolerance (26.7–29.5 V), 400 W rating, SMA package (DO-214AC), higher 1.5 mm profile | Larger footprint and lower thermal performance than SMF; not AEC-Q101 qualified | Select when cost priority outweighs automotive qualification and board space constraints. |
| TPSMD24C | 24 V VRWM, ±5 % VBR, 400 W, SMC package (DO-214AB), 2.5 mm height, 100 pF capacitance | Lower capacitance suits high-speed data lines but larger size limits dense layouts; no AEC-Q101 listing | Prefer for USB 3.0 or HDMI protection where capacitance is critical and space allows. |

FAQ
What is the clamping voltage of the VTVS23GSMF-M3-18 at its rated peak pulse current?
The VTVS23GSMF-M3-18 has a maximum reverse clamping voltage (VC) of 38 V at its rated 38 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per standard test methods and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings. The VTVS23GSMF-M3-18 achieves this clamping performance while maintaining low leakage and stable operation across −55 °C to +175 °C.
Is the VTVS23GSMF-M3-18 AEC-Q101 qualified?
Yes, the VTVS23GSMF-M3-18 is AEC-Q101 qualified, as confirmed in Vishay's official documentation for the VTVSxxGSMF series. This qualification validates its reliability for automotive applications through rigorous stress testing including HTGB, HTRB, TCT, and ESD. The VTVS23GSMF-M3-18 meets all AEC-Q101 requirements for unidirectional TVS diodes, supporting use in engine control units, body electronics, and ADAS subsystems where automotive-grade component certification is mandatory.
What does the "G" in VTVS23GSMF-M3-18 indicate?
The "G" in VTVS23GSMF-M3-18 denotes ±2 % tolerance on the reverse breakdown voltage (VBR), distinguishing it from "A"-suffix variants (e.g., VTVS23ASMF-M3-18) which have ±5 % VBR tolerance. This tighter tolerance enables more precise system-level voltage margining and reduces design conservatism in safety-critical applications. The VTVS23GSMF-M3-18 maintains identical power rating (400 W), package (SMF), and environmental specs as its "A" counterpart - only VBR accuracy differs.
Can the VTVS23GSMF-M3-18 be used in bidirectional configurations?
No, the VTVS23GSMF-M3-18 is a unidirectional TVS diode and is not rated for bidirectional operation. Its electrical characteristics - including specified VRWM, VBR, and clamping behavior - apply only under reverse-bias conditions. For bidirectional protection (e.g., AC lines or differential data buses), two VTVS23GSMF-M3-18 devices must be connected in series opposition, or a dedicated bidirectional part such as VTVS23GSMF-BD should be selected. Using a single VTVS23GSMF-M3-18 in bidirectional mode risks forward conduction failure or inadequate clamping.
What is the junction capacitance of the VTVS23GSMF-M3-18 and how does it affect high-speed signal lines?
The VTVS23GSMF-M3-18 has a typical junction capacitance (CD) of 480 pF at VR = 0 V and f = 1 MHz. This capacitance introduces signal attenuation and rise-time degradation on high-speed lines - making it suitable for interfaces up to ~10 Mbps (e.g., CAN FD, RS-485, LIN) but generally unsuitable for USB 2.0 (480 Mbps) or HDMI without additional filtering. Designers must place the VTVS23GSMF-M3-18 as close as possible to the protected connector and verify eye diagram integrity in final layout simulations.
