Product details
Overview
VTVS58ASMF-M3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for robust ESD and surge protection on low-voltage DC lines. It features a 57.6 V stand-off voltage (VRWM), 64.6–71.4 V reverse breakdown voltage (VBR), 98 A peak pulse current (IPPM), and clamps to ≤98 V at rated pulse, targeting automotive infotainment power rails and industrial sensor interfaces.
For engineers reviewing the VTVS58ASMF-M3-18 datasheet, VTVS58ASMF-M3-18 pinout, VTVS58ASMF-M3-18 application, or VTVS58ASMF-M3-18 equivalent, key selection criteria include its ±5 % VBR tolerance, 245 pF junction capacitance at 0 V, 175 °C max junction temperature, and AEC-Q101 qualification status - critical for automotive-grade reliability validation and board-level ESD immunity design.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 64.6–71.4 V breakdown range at 1 mA test current. Its clamping action limits transients to ≤98 V under 10/1000 μs waveform stress, with thermal resistance of 20 K/W to infinite heat sink.
It delivers ±30 kV ESD protection per IEC 61000-4-2 (contact and air discharge), uses halogen-free molding compound, and is qualified to AEC-Q101 - confirming suitability for automotive under-hood and cabin electronics where high-temperature stability and solder-reflow compatibility are mandatory.

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 | Same 58 V nominal breakdown but SMA package (DO-214AC); 400 W rating; ±5 % VBR; 274 pF capacitance | Larger footprint (4.5 mm × 2.7 mm); higher thermal resistance (35 K/W); not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and board space constraints |
| SMCJ58A | Higher 1500 W rating; same 58 V nominal breakdown; DO-214AB package; 270 pF capacitance | Designed for higher-energy transients (e.g., ISO 7637-2 Pulse 5a); larger size (7.1 mm × 6.2 mm); no AEC-Q101 listing | Choose for industrial power supplies requiring >1 kW surge handling, not automotive ECU space-limited designs |
Compared with SMAJ58A and SMCJ58A, VTVS58ASMF-M3-18 offers superior automotive qualification, smaller SMF footprint, and lower capacitance - making it optimal for space-constrained, high-reliability 12 V/24 V systems where ESD robustness and thermal performance are prioritized over raw power rating.

FAQ
What is the maximum clamping voltage of the VTVS58ASMF-M3-18 under full-rated surge conditions?
The VTVS58ASMF-M3-18 clamps to a maximum of 98 V when subjected to its rated 3.89 A peak pulse current (10/1000 μs waveform). This value is measured at the device terminals and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events, ensuring downstream ICs remain within safe operating limits.
Is VTVS58ASMF-M3-18 qualified for automotive use according to industry standards?
Yes, VTVS58ASMF-M3-18 is AEC-Q101 qualified, confirming its reliability for automotive applications including engine control, body electronics, and infotainment systems. The qualification covers stress tests such as high-temperature reverse bias, temperature cycling, and mechanical shock - all performed per the AEC-Q101 standard revision applicable at time of certification.
What is the junction capacitance of VTVS58ASMF-M3-18 and how does it affect high-speed signal lines?
The VTVS58ASMF-M3-18 exhibits 245 pF typical junction capacitance at 0 V reverse bias and 1 MHz frequency. While suitable for DC power rail protection and low-speed buses like CAN, this capacitance may attenuate edges or cause jitter on signals above ~10 Mbps; for USB or Ethernet, lower-capacitance TVS variants are recommended.
Can VTVS58ASMF-M3-18 be used in both wave and reflow soldering processes?
Yes, VTVS58ASMF-M3-18 is fully compatible with both wave and reflow soldering. Its SMF (DO-219AB) package supports peak reflow temperatures up to 260 °C per J-STD-020, and its halogen-free molding compound meets IPC-J-STD-020 moisture sensitivity level 1 - eliminating pre-bake requirements and enabling standard SMT assembly flow.
What is the reverse leakage current specification for VTVS58ASMF-M3-18 at its maximum working voltage?
At its maximum stand-off voltage of 57.6 V (VRWM), the VTVS58ASMF-M3-18 guarantees reverse leakage current ≤0.05 μA at 25 °C ambient. This ultra-low leakage preserves power efficiency in always-on automotive modules and prevents false triggering in precision sensor bias networks.
