Product details
Overview
VTVS58ASMF-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. It features a 57.6 V stand-off voltage (VRWM), 64.6–71.4 V reverse breakdown voltage (VBR at IT = 1 mA), clamps to ≤98 V at 3.89 A peak pulse current (10/1000 μs), and delivers ±30 kV IEC 61000-4-2 ESD immunity - used in automotive infotainment power rails and industrial sensor interfaces.
For engineers reviewing the VTVS58ASMF-M3-08 datasheet, VTVS58ASMF-M3-08 pinout, VTVS58ASMF-M3-08 application, or VTVS58ASMF-M3-08 equivalent, key selection criteria include its 98 V clamping voltage at rated IPPM, ±5 % VBR tolerance, 245 pF junction capacitance at 0 V, 175 °C max junction temperature, and compatibility with SOD-123W footprint for space-constrained PCB layouts.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 64.6–71.4 V breakdown range. Its low 20 K/W thermal resistance (junction-to-lead, mounted on infinite heat sink) enables reliable 400 W peak pulse power dissipation under 10/1000 μs transients without thermal runaway.
The device achieves fast response via "Low-Noise" technology, with sub-nanosecond turn-on and stable clamping down to 1.8 V forward voltage at 50 A. Its halogen-free molding compound, MSL Level 1 rating, and reflow-solderable SMF package support automotive-grade assembly per AEC-Q101 qualification requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A-E3/5A | Same 58 V nominal VRWM, but SMA package (DO-214AC); 400 W rating, 100 V VC @ 3.8 A | Larger footprint (4.5 × 2.7 mm vs. 3.9 × 1.9 mm); less suitable for ultra-dense layouts | Select when existing SMA land pattern exists or higher thermal mass is needed. |
| 1.5SMC58A | Higher 58 V VRWM, but SMC package (DO-214AB); 1500 W rating, 93.6 V VC @ 16.1 A | Designed for higher-energy surges (IEC 61000-4-5 Level 4); not drop-in due to size and thermal profile | Choose for industrial AC-coupled lines where 1500 W capability outweighs board space penalty. |
Compared with SMAJ58A-E3/5A and 1.5SMC58A, VTVS58ASMF-M3-08 offers superior space efficiency and MSL Level 1 reliability for automotive PCBs, while maintaining identical clamping performance at lower surge currents - ideal for compact, high-volume embedded systems.

FAQ
What is the clamping voltage of VTVS58ASMF-M3-08 at its rated peak pulse current?
The VTVS58ASMF-M3-08 clamps to a maximum of 98 V at its rated peak pulse current of 3.89 A (10/1000 μs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on the protected circuit during surge events, ensuring downstream ICs remain within safe operating limits.
Is VTVS58ASMF-M3-08 qualified for automotive applications?
Yes, VTVS58ASMF-M3-08 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, and ESD robustness. Its 175 °C maximum junction temperature and MSL Level 1 rating make it suitable for under-hood and cabin-mounted automotive electronics such as body control modules and infotainment systems.
What does the "-M3-08" suffix indicate in VTVS58ASMF-M3-08?
The "-M3-08" suffix denotes tape-and-reel packaging: "M3" specifies lead (Pb)-free, RoHS-compliant tin plating, and "-08" indicates 3,000 units per 7-inch reel (8 mm tape width, minimum order quantity 30,000 units). This format supports automated SMT placement in high-volume manufacturing.
How does the 245 pF capacitance of VTVS58ASMF-M3-08 affect high-speed signal lines?
The 245 pF junction capacitance of VTVS58ASMF-M3-08 is measured at 0 V bias and 1 MHz; it remains below 100 pF above 5 V reverse bias. This characteristic makes VTVS58ASMF-M3-08 appropriate for protecting low-speed digital and analog lines (e.g., LIN, sensor outputs), but not recommended for USB 2.0 or HDMI without additional filtering.
Can VTVS58ASMF-M3-08 be used in bidirectional protection configurations?
No - VTVS58ASMF-M3-08 is a unidirectional TVS diode, optimized for clamping positive transients to ground. For bidirectional protection (e.g., AC lines or differential buses), two VTVS58ASMF-M3-08 devices must be connected in series opposition, or a dedicated bidirectional part like VTVS58BSMF-M3-08 should be selected instead.
