Product details
Overview
VTVS5V0ASMF-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 5.0 V DC power rails and signal lines. It features 6.4 V to 7.0 V reverse breakdown voltage (VBR), 5.00 V maximum stand-off voltage (VRWM), 42.95 A peak pulse current (IPPM), 8.9 V maximum clamping voltage (VC) at IPPM, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive infotainment power inputs and USB Type-C VBUS lines.
For engineers reviewing the VTVS5V0ASMF-M3-18 datasheet, VTVS5V0ASMF-M3-18 pinout, VTVS5V0ASMF-M3-18 application, or VTVS5V0ASMF-M3-18 equivalent, key selection criteria include clamping performance under 10/1000 μs surge, low leakage (<5 μA at VRWM), halogen-free SOD-123W-compatible packaging, and AEC-Q101 qualification readiness for automotive front-end circuits.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 6.4–7.0 V breakdown range at 1 mA test current. Its low 8.9 V clamping voltage at 42.95 A ensures protected ICs see minimal overvoltage during 400 W transients.
Designed for surface-mount reflow soldering per J-STD-020 MSL level 1, it delivers thermal resistance of 20 K/W (junction-to-lead) and operates across -55 °C to +175 °C junction temperature - enabling use in under-hood automotive modules and industrial power supplies where ambient temperatures exceed 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.00 V - Maximum continuous reverse operating voltage before leakage rises above 5 μA; matches standard 5 V logic and power rail systems. |
| VBR (min/max) | 6.4 V / 7.0 V - Breakdown occurs within this band at 1 mA; ensures reliable triggering without premature conduction. |
| VC @ IPPM | 8.9 V - Clamps 42.95 A 10/1000 μs surge to ≤8.9 V, limiting stress on downstream 5 V-rated ICs like USB controllers or CAN transceivers. |
| PPPM | 400 W - Peak pulse power handling per 10/1000 μs waveform; sufficient for ISO 7637-2 Pulse 1/2a/3a and IEC 61000-4-5 Level 3 surges. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Protects interfaces exposed to direct human touch or proximity discharge in handheld and dashboard-mounted devices. |
| Capacitance | 2095 pF @ 0 V - High capacitance limits use to DC/low-frequency power rails (e.g., VBUS, VDD_IO), not high-speed data lines. |
| Package | SMF (DO-219AB) - Low-profile 3.9 × 1.9 × 1.08 mm outline compatible with SOD-123W footprints; supports automated placement and reflow. |
Pinout & Package
SMF (DO-219AB) package: cathode-marked, surface-mount, single-diode configuration with two terminals - anode and cathode - in a compact 3.9 mm × 1.9 mm × 1.08 mm molded body. Compatible with SOD-123W PCB footprints and wave/reflow soldering per JEDEC J-STD-020 MSL level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input side of protected line | Connected to the line requiring protection (e.g., VBUS input); conducts during forward-biased ESD events. |
| Cathode | Ground reference / clamp node | Connected to system ground or low-impedance return path; provides low-impedance shunt during reverse-biased transient clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Handles high-energy transients per 10/1000 μs waveform without degradation - suitable for automotive load-dump adjacent circuits. |
| ±5 % VBR tolerance | Tight breakdown control enables predictable clamping onset across production lots, reducing design margin uncertainty. |
| "Low-Noise" fast response | Sub-nanosecond response time prevents voltage overshoot before clamping engages - critical for protecting sensitive analog and mixed-signal ICs. |
| AEC-Q101 qualification option | VTVS5V0ASMF-M3-18 variant supports automotive-grade reliability testing (HTOL, TCT, ESD), enabling use in qualified modules without additional qualification effort. |
| Halogen-free & RoHS-compliant | Meets automotive and industrial environmental compliance requirements; tin-plated terminations ensure solderability and long-term interconnect integrity. |
Applications
| Automotive Infotainment Power Input | Industrial PLC Digital I/O Protection |
|---|---|

Use Scenario: 5 V digital input channel on programmable logic controller receiving signals from external sensors in factory-floor environments with frequent ESD events. IC Role / Device Role / Timing Role: Standoff protector on signal line, conducting only during overvoltage - maintains signal integrity during normal operation with <5 μA leakage. Use Value: Withstands repeated ±30 kV contact discharges without parameter shift, eliminating field failures caused by operator-induced ESD on terminal blocks. |
| USB Type-C VBUS Line Protection | Smart Meter Power Supply Rail |
|
Use Scenario: VBUS line in USB-C receptacle subjected to hot-plug surges, cable-induced transients, and accidental 12 V misconnection. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 5 V power path; coordinated with upstream fuse and secondary ceramic capacitor for full surge chain. Use Value: Clamps misapplied 12 V to ≤8.9 V within nanoseconds, allowing time for fuse blow while preserving USB PD controller functionality. |
Use Scenario: 5 V auxiliary supply in utility smart meters exposed to lightning-induced surges on AC mains-coupled auxiliary rails. IC Role / Device Role / Timing Role: Secondary-stage TVS after MOV-based primary protection; absorbs residual energy that passes through front-end filtering. Use Value: 400 W rating sustains multiple 10/1000 μs surges without parametric drift, ensuring long-term meter accuracy and communication uptime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Same 5.0 V VRWM, but 400 W rating uses 8.3 × 6.2 mm SMA package; higher RthJA (50 K/W vs. 20 K/W). | Larger footprint and lower thermal efficiency limit use in space-constrained automotive modules. | Select when legacy SMA layout exists and thermal derating is acceptable. |
| TPSMD5.0 | 5.0 V VRWM, 400 W, but 2200 pF capacitance and no AEC-Q101 option; VC = 9.2 V at same IPPM. | Higher clamping voltage reduces margin for 5 V ICs; lacks automotive qualification path. | Prefer for cost-sensitive industrial power supplies where AEC-Q101 is unnecessary. |
Compared with SMAJ5.0A and TPSMD5.0, VTVS5V0ASMF-M3-18 offers superior thermal performance in a smaller DO-219AB footprint, tighter VBR tolerance, and direct AEC-Q101 qualification support - making it optimal for next-generation automotive and compact industrial designs requiring robust, space-efficient clamping.

FAQ
What is the maximum clamping voltage of VTVS5V0ASMF-M3-18 under surge conditions?
The VTVS5V0ASMF-M3-18 has a maximum reverse clamping voltage (VC) of 8.9 V at its rated peak pulse current of 42.95 A using a 10/1000 μs waveform. This value is guaranteed across temperature and production lot, ensuring consistent protection for 5 V ICs without exceeding their absolute maximum ratings.
Is VTVS5V0ASMF-M3-18 qualified to AEC-Q101?
VTVS5V0ASMF-M3-18 is offered in an AEC-Q101-qualified version (e.g., VTVS5V0ASMF-HM3-18). The base VTVS5V0ASMF-M3-18 variant is built on the same die and process, supporting qualification-ready design-in; full AEC-Q101 test reports are available upon request for automotive program validation.
Can VTVS5V0ASMF-M3-18 be used on high-speed data lines like USB 2.0 or HDMI?
No - VTVS5V0ASMF-M3-18 has a typical capacitance of 2095 pF at 0 V, which would severely attenuate signal integrity on high-speed differential lines. It is intended exclusively for DC power rails and low-frequency signal lines (e.g., reset, enable, or GPIO) where capacitance is non-critical.
What is the leakage current specification for VTVS5V0ASMF-M3-18 at its rated standoff voltage?
At VRWM = 5.00 V and Tamb = 25 °C, VTVS5V0ASMF-M3-18 exhibits a maximum reverse leakage current (IR) of 5 μA. This low leakage ensures minimal power loss and avoids false triggering in always-on 5 V monitoring circuits.
How does the SMF (DO-219AB) package of VTVS5V0ASMF-M3-18 compare to SOD-123W in PCB layout?
The SMF (DO-219AB) package of VTVS5V0ASMF-M3-18 shares identical pad dimensions and footprint compatibility with SOD-123W - including 1.3 mm × 1.3 mm pad spacing and 2.9 mm × 1.4 mm overall land pattern - enabling drop-in replacement without PCB redesign while delivering improved thermal resistance (20 K/W vs. ~35 K/W for SOD-123W).
