Product details
Overview
VTVS28GSMF-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 27.9 V maximum stand-off voltage (VRWM), 32.39–33.72 V reverse breakdown voltage (VBR) at 1 mA, and clamps to ≤47 V at 8.45 A peak pulse current (10/1000 μs), supporting automotive infotainment power rail protection.
For engineers reviewing the VTVS28GSMF-M3-08 datasheet, VTVS28GSMF-M3-08 pinout, VTVS28GSMF-M3-08 application, or VTVS28GSMF-M3-08 equivalent, key selection criteria include ±2 % VBR tolerance, 400 W peak pulse power rating, IEC 61000-4-2 ±30 kV ESD immunity, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a unidirectional avalanche diode, leveraging silicon planar technology to deliver fast response (<1 ns) clamping during transients. Its low dynamic impedance ensures stable clamping voltage across rated current, with thermal resistance RthJL = 20 K/W enabling robust power dissipation under repetitive surge conditions.
The SMF package supports wave and reflow soldering per J-STD-020 MSL level 1, with halogen-free molding compound and tin-plated terminations. Its 1.08 mm height and 3.9 × 1.9 mm footprint enable compact placement on high-density PCBs while maintaining mechanical robustness for automotive vibration environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform - sustains repeated surges without degradation) |
| Stand-off Voltage (VRWM) | 27.9 V - maximum continuous reverse voltage before leakage exceeds 0.05 μA |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VTVS28ASMF-M3-08 | ±5 % VBR tolerance (31.4–34.7 V) vs. ±2 % for VTVS28GSMF-M3-08 | Suitable for non-critical industrial use where tighter voltage margin is not required | Select when cost sensitivity outweighs precision clamping needs |
| SMAJ28A | Same VRWM (28 V), but lower PPPM (400 W same), higher VC (48.4 V @ 8.3 A), no AEC-Q101 | Limited to commercial-grade applications; lacks automotive qualification and tighter VBR | Choose only for cost-driven consumer designs with relaxed reliability requirements |
Compared with VTVS28ASMF-M3-08 and SMAJ28A, VTVS28GSMF-M3-08 delivers superior voltage accuracy and automotive qualification-critical for safety-critical power rail protection where clamping consistency and long-term reliability directly impact system failure rates.

FAQ
What is the clamping voltage of VTVS28GSMF-M3-08 at its rated peak pulse current?
The VTVS28GSMF-M3-08 clamps to a maximum of 47 V at its rated peak pulse current of 8.45 A (10/1000 μs waveform). This value is specified in the Electrical Characteristics table and reflects worst-case reverse-biased clamping performance under standardized surge conditions, ensuring downstream circuitry remains within safe operating limits during transient events.
Is VTVS28GSMF-M3-08 qualified for automotive applications?
Yes, VTVS28GSMF-M3-08 is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including body control modules, infotainment units, and power distribution networks. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life-ensuring reliability in harsh vehicle environments.
What does the "G" in VTVS28GSMF-M3-08 indicate?
The "G" in VTVS28GSMF-M3-08 denotes ±2 % tolerance on the reverse breakdown voltage (VBR), distinguishing it from "A"-suffix variants (e.g., VTVS28ASMF-M3-08) which have ±5 % VBR tolerance. This tighter tolerance enables more precise overvoltage protection thresholds in sensitive power rail applications.
Can VTVS28GSMF-M3-08 be used in bidirectional configurations?
No, VTVS28GSMF-M3-08 is a unidirectional TVS diode and must be used with correct polarity-cathode connected to the protected line, anode to ground. For bidirectional protection, two VTVS28GSMF-M3-08 devices would need back-to-back connection, or a dedicated bidirectional part such as VTVS28BGMF-M3-08 should be selected instead.
What is the moisture sensitivity level (MSL) rating for VTVS28GSMF-M3-08?
VTVS28GSMF-M3-08 has a moisture sensitivity level (MSL) rating of level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions (<30 °C / 60 % RH) without baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates floor-life constraints in high-volume SMT assembly.
