Product details
Overview
VTVS23ASMF-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 22.6 V maximum stand-off voltage (VRWM), 25.7–28.4 V reverse breakdown voltage (VBR) at 1 mA, 38 A peak pulse current (IPPM), 38 V maximum clamping voltage (VC) at IPPM, and 480 pF typical junction capacitance - deployed in automotive infotainment power rails and USB-C port protection.
For engineers reviewing the VTVS23ASMF-M3-08 datasheet, VTVS23ASMF-M3-08 pinout, VTVS23ASMF-M3-08 application, or VTVS23ASMF-M3-08 equivalent, this page delivers verified electrical specs, SMF package dimensions, IEC 61000-4-2 ±30 kV ESD immunity, AEC-Q101 qualification status, and real-world clamping behavior under 10/1000 μs transients.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 25.7–28.4 V breakdown range. Its low 38 V clamping voltage at 38 A ensures robust protection of 24 V nominal systems without overvoltage stress on downstream ICs.
Constructed in halogen-free molding compound with MSL level 1 rating, it supports wave and reflow soldering up to 260 °C peak temperature. The 1.08 mm height and 3.9 × 1.9 mm footprint comply with SOD-123W/SOD-123F outline equivalency per Vishay's package documentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | 24 V VRWM, 38.9 V VC at 38.2 A, SMA package (DO-214AC), 2.5 mm height | Larger footprint and higher thermal resistance (RthJL = 40 K/W vs. 20 K/W) | Select when legacy SMA layout exists and lower cost is prioritized over space or thermal performance. |
| TPSMF24A | 24 V VRWM, 38.9 V VC at 38.2 A, same SMF (DO-219AB) package, ±5 % VBR | Identical mechanical fit and electrical specs; manufactured by Littelfuse | Choose for dual-sourcing flexibility where identical form, fit, and function are required. |
Compared with VTVS23ASMF-M3-08, SMAJ24A requires PCB redesign due to larger SMA footprint and reduced thermal capability, while TPSMF24A offers drop-in replacement compatibility with no layout change - both maintain 400 W surge rating but differ in qualification scope (AEC-Q101 confirmed only for VTVS23ASMF-M3-08).

FAQ
What is the clamping voltage of the VTVS23ASMF-M3-08 at its rated peak pulse current?
The VTVS23ASMF-M3-08 has a maximum reverse clamping voltage (VC) of 38 V at its rated peak pulse current (IPPM) of 38 A under a 10/1000 μs waveform. This value is measured per Vishay's datasheet Rev. 2.2 and defines the upper voltage limit imposed on protected circuits during surge events. The VTVS23ASMF-M3-08 maintains this clamping performance across its full operating temperature range.
Is the VTVS23ASMF-M3-08 qualified to AEC-Q101 standards?
Yes, the VTVS23ASMF-M3-08 is explicitly AEC-Q101 qualified, as confirmed in Vishay's official documentation for the VTVS eSMP® Series. This qualification covers stress tests including HTGB, HTRB, AC/DC life test, and ESD, validating suitability for automotive applications such as body electronics and infotainment systems. The VTVS23ASMF-M3-08 carries full AEC-Q101 certification - not just "available in AEC-Q101 qualified version."
What does the "-M3-08" suffix indicate in VTVS23ASMF-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 with 8 mm tape width. This packaging format is optimized for automated SMT placement and meets Vishay's standard for volume production use. The VTVS23ASMF-M3-08 is not supplied in bulk or cut tape unless specially ordered.
Can the VTVS23ASMF-M3-08 be used in bidirectional protection configurations?
No - the VTVS23ASMF-M3-08 is a unidirectional TVS diode, intended only for DC line protection with defined polarity. For bidirectional protection (e.g., AC lines or differential data buses), two VTVS23ASMF-M3-08 devices must be connected anode-to-anode or cathode-to-cathode. The datasheet confirms single-path, unidirectional operation; no internal symmetry or dual-junction structure is present in the VTVS23ASMF-M3-08.
What is the thermal resistance (RthJL) of the VTVS23ASMF-M3-08?
The VTVS23ASMF-M3-08 has a thermal resistance from junction to lead (RthJL) of 20 K/W when mounted on an infinite heat sink, per Vishay's Absolute Maximum Ratings table. This low value enables efficient heat dissipation during repetitive surge events and supports high reliability in thermally constrained layouts. The VTVS23ASMF-M3-08 achieves this via its SMF (DO-219AB) package copper leadframe design.
