Product details
Overview
VTVS12GSMF-HM3-08 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 12.4 V maximum stand-off voltage (VRWM), 14.41–15.00 V reverse breakdown voltage (VBR) at 1 mA, 20.1 V maximum clamping voltage (VC) at 19.53 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity-used in automotive infotainment power rails and USB-C port protection.
For engineers reviewing the VTVS12GSMF-HM3-08 datasheet, VTVS12GSMF-HM3-08 pinout, VTVS12GSMF-HM3-08 application, or VTVS12GSMF-HM3-08 equivalent, this part delivers precise 2% VBR tolerance, halogen-free construction, AEC-Q101 qualification, and compatibility with SOD-123W footprint-critical for high-reliability automotive and industrial interface protection design.
Technical Context
This device operates as a unidirectional avalanche diode, triggering at 14.41–15.00 V to clamp transients while maintaining 12.4 V working voltage. Its 20.1 V clamping voltage at 19.53 A (10/1000 μs) ensures robust protection of downstream 12 V logic and analog circuitry without overvoltage stress.
Constructed in the low-profile SMF (DO-219AB) package with MSL level 1 rating and 260 °C reflow compatibility, it supports automated assembly and achieves 175 °C max junction temperature-enabling use in under-hood automotive modules and thermally constrained IoT edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Use Scenario: Protecting LIN bus power domains and sensor supply lines in door modules and lighting controllers exposed to battery transients. IC Role / Device Role / Timing Role: Secondary-level clamp after primary fuse and choke; handles residual spikes missed by bulk filtering. Use Value: AEC-Q101 qualification and 175 °C TJ max guarantee functional safety compliance for ASIL-B subsystems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VTVS12ASMF-HM3-08 | ±5 % VBR tolerance (14.0–15.4 V) vs. ±2 % for VTVS12GSMF-HM3-08 | Lower precision clamping; suitable where 15.4 V upper limit is acceptable | Select when cost sensitivity outweighs need for tight VBR control in non-safety-critical 12 V lines |
| SMAJ12A-E3/57T | Same VRWM (12 V), but 300 W PPPM (vs. 400 W) and no AEC-Q101 qualification | Limited to commercial-grade industrial use; not validated for automotive temperature cycling or humidity testing | Choose only for non-automotive applications where 100 W lower surge margin is acceptable |
Compared with VTVS12ASMF-HM3-08 and SMAJ12A-E3/57T, VTVS12GSMF-HM3-08 provides superior clamping precision, higher surge handling, and automotive-grade reliability-making it the optimal choice for safety-critical 12 V rail protection where long-term field stability is mandatory.

FAQ
What is the clamping voltage of VTVS12GSMF-HM3-08 at its rated peak pulse current?
The VTVS12GSMF-HM3-08 has a maximum reverse clamping voltage (VC) of 20.1 V at its rated peak pulse current (IPPM) of 19.53 A, measured using a 10/1000 μs waveform. This value ensures protected circuits remain below critical overvoltage thresholds during surge events. The VTVS12GSMF-HM3-08 maintains this performance across its full operating temperature range of −55 °C to +175 °C.
Is VTVS12GSMF-HM3-08 qualified for automotive applications?
Yes, VTVS12GSMF-HM3-08 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, and ESD robustness required for automotive electronic components. This qualification covers its use in body electronics, infotainment, and BCM applications. The VTVS12GSMF-HM3-08 also supports reflow soldering up to 260 °C, meeting automotive manufacturing standards.
What does the "G" in VTVS12GSMF-HM3-08 indicate?
The "G" in VTVS12GSMF-HM3-08 denotes ±2 % tolerance on the reverse breakdown voltage (VBR), distinguishing it from "A"-suffix variants with ±5 % tolerance. For VTVS12GSMF-HM3-08, VBR is specified as 14.41–15.00 V at IT = 1 mA. This tighter tolerance enables more predictable clamping behavior in precision 12 V protection schemes. The VTVS12GSMF-HM3-08 leverages this for improved margin control in safety-critical designs.
Can VTVS12GSMF-HM3-08 replace SOD-123W footprint devices?
Yes, VTVS12GSMF-HM3-08 uses the SMF (DO-219AB) package, which is explicitly stated as compatible with the SOD-123W case outline. Its mechanical dimensions (3.9 mm × 1.9 mm × 1.08 mm) and cathode-bar marking align with SOD-123W land patterns. No PCB modification is needed when upgrading from legacy SOD-123W TVS diodes-provided thermal and electrical requirements are verified. The VTVS12GSMF-HM3-08 retains full functionality in that footprint.
What is the maximum junction temperature rating for VTVS12GSMF-HM3-08?
The VTVS12GSMF-HM3-08 has a maximum junction temperature (TJ) rating of +175 °C, with a corresponding storage temperature range of −55 °C to +175 °C. This high-temperature capability supports deployment in under-hood automotive modules and industrial enclosures without forced cooling. Thermal resistance from junction to lead (RthJL) is 20 K/W when mounted on an infinite heat sink, enabling accurate thermal modeling for VTVS12GSMF-HM3-08 in high-power transient scenarios.
