Product details
Overview
VTVS58ASMF-HM3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection on low-voltage DC lines. It features a 57.6 V stand-off voltage (VRWM), 64.6–71.4 V reverse breakdown voltage (VBR), and clamps to ≤98 V at 3.89 A peak pulse current (IPPM) under 10/1000 μs waveform - deployed in automotive infotainment power rails and industrial sensor interfaces.
For engineers reviewing the VTVS58ASMF-HM3-18 datasheet, VTVS58ASMF-HM3-18 pinout, VTVS58ASMF-HM3-18 application, or VTVS58ASMF-HM3-18 equivalent, key selection criteria include its ±5 % VBR tolerance, 245 pF capacitance at 0 V, AEC-Q101 qualification readiness, halogen-free construction, and compatibility with SOD-123W footprint constraints.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging avalanche breakdown to divert transients above VRWM while maintaining low leakage (<0.05 μA) below that threshold. Its thermal resistance (RthJL = 20 K/W) and 175 °C max junction temperature support high-reliability operation in thermally constrained PCB layouts.
The device delivers IEC 61000-4-2 ESD immunity of ±30 kV contact/air discharge and achieves fast response via "Low-Noise" technology. Its 1.08 mm height and 3.9 × 1.9 mm outline meet space-critical requirements in automotive and industrial control modules.

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 (Vishay) | Same VRWM (58 V), but SMA package (DO-214AC); 400 W rating; ±5 % VBR; 250 pF | Larger footprint (4.5 × 2.7 mm); higher thermal resistance (RthJL = 35 K/W) | Select when board space allows larger package and higher thermal mass is needed for repeated surge duty. |
| 1.5SMC58A (ON Semiconductor) | Same VRWM (58 V); SMC package (DO-214AB); 1500 W rating; ±5 % VBR; 300 pF | Higher power handling but 3× capacitance; not AEC-Q101 qualified | Choose for non-automotive 1500 W surge requirements where signal bandwidth permits higher CD. |
Compared with SMAJ58A-E3/5A and 1.5SMC58A, VTVS58ASMF-HM3-18 offers superior space efficiency (3.9 × 1.9 mm), lower profile (1.08 mm), and verified AEC-Q101 qualification path - making it optimal for compact, automotive-grade power-rail protection where layout area and thermal constraints are critical.

FAQ
What is the maximum clamping voltage of VTVS58ASMF-HM3-18 under standard test conditions?
The VTVS58ASMF-HM3-18 clamps to a maximum of 98 V when subjected to its rated peak pulse current of 3.89 A using the 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on the protected circuit during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is VTVS58ASMF-HM3-18 qualified to AEC-Q101?
VTVS58ASMF-HM3-18 is part of the AEC-Q101-qualified eSMP® Series. While the base part number does not embed the qualification suffix, Vishay documents full AEC-Q101 compliance for the VTVS58ASMF family - including HTOL, TC, HAST, and ESD testing - with qualification reports available upon request for VTVS58ASMF-HM3-18.
What does the "HM3-18" suffix indicate in VTVS58ASMF-HM3-18?
In VTVS58ASMF-HM3-18, "H" denotes halogen-free construction, "M3" specifies tape-and-reel packaging on 7-inch reels (8 mm tape, 3K units per reel), and "-18" indicates RoHS-compliant, lead (Pb)-free terminations with 100 % matte tin plating - confirming full environmental compliance per JEDEC J-STD-609.
Can VTVS58ASMF-HM3-18 be used in bidirectional protection circuits?
No - VTVS58ASMF-HM3-18 is a unidirectional TVS diode, intended for DC line protection where polarity is fixed. For bidirectional applications (e.g., AC lines or data buses), a dedicated bidirectional variant such as VTVS58BSMF-HM3-18 must be selected, as the unidirectional design conducts only in reverse avalanche mode and blocks forward current beyond VF ≈ 1.8 V.
What is the thermal resistance junction-to-lead (RthJL) for VTVS58ASMF-HM3-18?
The thermal resistance junction-to-lead (RthJL) for VTVS58ASMF-HM3-18 is 20 K/W when mounted on an infinite heat sink. This parameter enables accurate junction temperature estimation under pulsed surge conditions and informs PCB copper pour design - especially important for repeated surge events in automotive body electronics.
