Product details
Overview
VTVS5V0ASMF-M3-08 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for primary ESD and surge protection on 5.0 V DC power rails and signal lines. It features 6.4 V to 7.0 V reverse breakdown voltage (VBR), 5.0 V maximum working voltage (VRWM), 42.95 A peak pulse current (IPPM), 8.9 V 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-M3-08 datasheet, VTVS5V0ASMF-M3-08 pinout, VTVS5V0ASMF-M3-08 application, or VTVS5V0ASMF-M3-08 equivalent, this page delivers verified electrical specs, SMF package dimensions, clamping performance under 10/1000 μs transients, IEC 61000-4-2 compliance data, and direct alternatives with documented tolerance and qualification differences.
Technical Context
This device operates as a unidirectional avalanche diode, 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 robust protection of downstream 5 V logic without overstressing ICs during 10/1000 μs surges.
It achieves ±30 kV contact/air discharge ESD immunity per IEC 61000-4-2 and maintains stable operation from −55 °C to +175 °C junction temperature. The SMF package supports wave and reflow soldering, complies with halogen-free and RoHS requirements, and meets AEC-Q101 qualification when specified with "H" suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse operating voltage before conduction begins; matches standard 5 V supply rails. |
| VBR (min/max) | 6.4 V / 7.0 V at IT = 1 mA - Tight ±5 % tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | 8.9 V at 42.95 A (10/1000 μs) - Limits transient voltage seen by protected circuitry to safe margin below 10 V logic thresholds. |
| PPPM | 400 W - Sustains high-energy surges typical of ISO 7637-2 pulse 1/2a/5a in automotive environments. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Eliminates need for secondary ESD stages in USB, HDMI, and sensor interfaces. |
| Junction Temp | −55 °C to +175 °C - Enables use in under-hood automotive modules and industrial power supplies without derating. |
| Capacitance | 2095 pF at VR = 0 V, 1 MHz - Suitable for DC power rail protection; not intended for high-speed data line applications. |

IC Role / Device Role / Timing Role: First-line ESD clamp on VBUS path, positioned immediately after connector to minimize trace inductance. Use Value: Delivers ±30 kV IEC 61000-4-2 contact discharge protection while adding only 2095 pF capacitance - no impact on USB 2.0 signal integrity. |
Use Scenario: Securing RS-485 transceiver VCC rail in utility smart meters subjected to lightning-induced surges on AC mains coupling paths. IC Role / Device Role / Timing Role: Standoff-rated TVS on isolated 5 V supply feeding communication ICs, coordinated with primary MOV-based AC-side protection.

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 ±10 % VBR tolerance (6.4–7.7 V); 400 W rating; SMA package (larger, 4.5 mm × 2.7 mm). | Higher VBR spread increases risk of premature conduction in precision 5 V systems; SMA footprint requires PCB redesign. | Select when cost sensitivity outweighs tight VBR control and board space is unconstrained. |
| VTVS5V0GSMF-M3-08 | Identical SMF package and 5.0 V VRWM, but ±2 % VBR (6.57–6.84 V); same 400 W rating and 8.9 V VC. | Narrower breakdown tolerance enables tighter design margins in safety-critical automotive modules requiring AEC-Q101 validation. | Choose for ASIL-B systems or where <0.3 V VBR variation is mandatory for fault detection algorithms. |
Compared with SMAJ5.0A, VTVS5V0ASMF-M3-08 offers tighter ±5 % VBR control and smaller SMF footprint; versus VTVS5V0GSMF-M3-08, it trades ±2 % precision for lower cost while retaining identical clamping and thermal performance.

FAQ
What is the clamping voltage of VTVS5V0ASMF-M3-08 at its rated peak pulse current?
The VTVS5V0ASMF-M3-08 has a maximum reverse clamping voltage (VC) of 8.9 V at its rated peak pulse current (IPPM) of 42.95 A under a 10/1000 μs waveform. This value is measured per the absolute maximum ratings table in Vishay document 85891 and ensures protected circuits remain below critical 10 V thresholds during surge events. The VTVS5V0ASMF-M3-08 maintains this clamping performance across its full operating temperature range.
Is VTVS5V0ASMF-M3-08 suitable for protecting high-speed data lines like USB 3.0 or HDMI?
No, VTVS5V0ASMF-M3-08 is not suitable for high-speed data lines due to its 2095 pF typical junction capacitance at 0 V bias, which would severely degrade signal integrity above ~10 MHz. It is optimized for DC power rail and low-frequency signal protection - such as USB Type-C VBUS (DC), automotive sensor supply lines, or industrial 5 V logic buses. For high-speed interfaces, Vishay offers specialized low-capacitance TVS arrays like the TPDxxSxx series. The VTVS5V0ASMF-M3-08 must be applied only where capacitance is non-critical.
Does VTVS5V0ASMF-M3-08 meet AEC-Q101 qualification?
The VTVS5V0ASMF-M3-08 itself is not AEC-Q101 qualified; that qualification applies only to variants with the "H" prefix, such as VTVS5V0ASMF-HM3-08. The "M3-08" suffix denotes tape-and-reel packaging (3,000 pcs per 7″ reel) and RoHS-compliant tin plating, but does not imply automotive qualification. Engineers requiring AEC-Q101 must specify the H-suffix part. The VTVS5V0ASMF-M3-08 remains fully compliant with IEC 61000-4-2 and operates reliably from −55 °C to +175 °C.
What is the thermal resistance of VTVS5V0ASMF-M3-08, and how does it affect power handling?
The VTVS5V0ASMF-M3-08 has a thermal resistance (RthJL) of 20 K/W from junction to lead when mounted on an infinite heat sink. This value determines how effectively heat generated during transient events dissipates into the PCB copper. At 400 W peak power, a 20 K/W RthJL yields a theoretical 8,000 K rise - but since energy is delivered in milliseconds, actual junction temperature rise depends on pulse duration and PCB copper area. The VTVS5V0ASMF-M3-08 relies on short-duration pulse capability rather than steady-state dissipation.
How does the SMF package of VTVS5V0ASMF-M3-08 compare to SOD-123W in layout implementation?
The SMF (DO-219AB) package used by VTVS5V0ASMF-M3-08 is mechanically and electrically compatible with SOD-123W footprints per Vishay's documentation, sharing identical 3.9 mm × 1.9 mm outline and 1.08 mm height. However, SMF features reinforced molding compound and tighter dimensional tolerances, enabling higher reliability in automated assembly. The VTVS5V0ASMF-M3-08 can be placed on existing SOD-123W layouts without modification, but optimal performance requires adherence to Vishay's recommended 1.3 mm × 1.3 mm pad dimensions and 2.9 mm center-to-center spacing.
