Product details
Overview
VTVS3V3GSMF-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 signal lines. It features a 3.3 V maximum stand-off voltage (VRWM), ±2 % tolerance on avalanche breakdown voltage (6.57–6.84 V at IT = 1 mA), 8.9 V maximum reverse clamping voltage at 43.99 A peak pulse current (10/1000 μs), and 2095 pF typical junction capacitance at 0 V.
For engineers reviewing the VTVS3V3GSMF-M3-08 datasheet, VTVS3V3GSMF-M3-08 pinout, VTVS3V3GSMF-M3-08 application, or VTVS3V3GSMF-M3-08 equivalent, key selection criteria include IEC 61000-4-2 ±30 kV contact/air discharge compliance, low-profile SOD-123W-compatible footprint, AEC-Q101 qualification readiness, thermal resistance of 20 K/W, and operation across -55 °C to +175 °C junction temperature range.
Technical Context
This TVS diode operates as a unidirectional clamping device, triggering into avalanche conduction when transient voltage exceeds its 6.57–6.84 V breakdown threshold. Its low-noise architecture delivers sub-nanosecond response time, enabling effective suppression of fast-rising ESD events before downstream ICs are damaged.
The device is optimized for low-voltage interfaces such as USB 2.0, HDMI, LVDS, and automotive sensor lines where VRWM ≤ 3.3 V is required. Its 2095 pF capacitance is specified at 0 V and 1 MHz, and clamping performance remains stable up to 175 °C junction temperature with no derating required below that limit.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ3.3A-E3/57T | ±5 % VBR tolerance (6.4–7.0 V); 400 W rating; SMA package (larger footprint, higher thermal resistance) | Higher VBR spread increases risk of premature conduction in tight-margin 3.3 V systems | Select when cost sensitivity outweighs precision clamping or board space is not constrained |
| TPD4E001DPYR | Quad-channel ESD array; 3.6 V VRWM; 12 pF per channel; 8 kV contact IEC 61000-4-2 | Lower capacitance but lower surge rating (20 W per line); not rated for 400 W 10/1000 μs transients | Select for high-speed digital buses requiring ultra-low capacitance where only ESD-not surge-is the threat |
Compared with SMAJ3.3A-E3/57T and TPD4E001DPYR, VTVS3V3GSMF-M3-08 provides tighter ±2 % breakdown control and superior 400 W surge handling in a smaller DO-219AB package, making it optimal for automotive and industrial applications demanding both precision and ruggedness.

FAQ
What is the clamping voltage of VTVS3V3GSMF-M3-08 at its rated peak pulse current?
The VTVS3V3GSMF-M3-08 exhibits a maximum reverse clamping voltage (VC) of 8.9 V when subjected to its rated peak pulse current of 43.99 A under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on the protected circuit during a full 400 W transient event. The clamping performance is guaranteed across the full -55 °C to +175 °C operating temperature range without derating.
Is VTVS3V3GSMF-M3-08 qualified to AEC-Q101?
VTVS3V3GSMF-M3-08 is offered in an AEC-Q101-qualified version (denoted by "H" in ordering code, e.g., VTVS3V3GSMF-HM3-08). The base VTVS3V3GSMF-M3-08 variant is built on the same die and process, and shares identical electrical characteristics and construction-but formal AEC-Q101 test reports apply only to the "H"-suffixed part number. Customers requiring automotive qualification must specify the HM3-08 variant.
How does the ±2 % VBR tolerance of VTVS3V3GSMF-M3-08 improve system protection compared to ±5 % variants?
The ±2 % breakdown voltage tolerance (6.57–6.84 V) of VTVS3V3GSMF-M3-08 ensures more consistent and predictable clamping onset versus ±5 % parts like VTVS3V3ASMF-M3-08 (6.4–7.0 V). In 3.3 V systems with narrow voltage margins-such as those using 3.3 V LDOs with 100 mV dropout-this tighter tolerance reduces risk of false triggering during normal operation while maintaining robust protection margin above VRWM.
Can VTVS3V3GSMF-M3-08 be used in bidirectional protection configurations?
VTVS3V3GSMF-M3-08 is a unidirectional TVS diode and cannot provide symmetrical clamping alone. However, it can be deployed in a bidirectional configuration by connecting two units in series opposition (anode-to-anode or cathode-to-cathode) across a differential line. This arrangement delivers balanced ±8.9 V clamping and is commonly used for RS-485, CAN, or other balanced interfaces where both polarities of surge must be suppressed.
What is the thermal resistance and maximum power dissipation capability of VTVS3V3GSMF-M3-08?
VTVS3V3GSMF-M3-08 has a thermal resistance RthJL of 20 K/W when mounted on an infinite heat sink, meaning it can sustain continuous power dissipation up to ~2.5 W before reaching its 175 °C maximum junction temperature at 25 °C ambient. However, its primary rating is pulsed: 400 W peak for 10/1000 μs. For repetitive surges, duty cycle and average power must remain within safe SOA limits defined in the Vishay datasheet Figure 5 and 6.
