Product details
Overview
VTVS15GSMF-M3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, designed for ESD and surge protection of low-voltage DC lines. It features 15.1 V stand-off voltage (VRWM), 17.6–18.31 V reverse breakdown voltage (VBR) at 1 mA, 25 V maximum clamping voltage (VC) at 15.89 A peak pulse current, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive infotainment power rails and USB-C port protection.
For engineers reviewing the VTVS15GSMF-M3-18 datasheet, VTVS15GSMF-M3-18 pinout, VTVS15GSMF-M3-18 application, or VTVS15GSMF-M3-18 equivalent, key selection criteria include its ±2 % VBR tolerance, 684 pF junction capacitance at 0 V, 175 °C max junction temperature, halogen-free construction, and compatibility with SOD-123W footprint for high-reliability board-level surge suppression.
Technical Context
This TVS diode operates as a unidirectional clamping device, triggering into avalanche conduction when reverse voltage exceeds its 17.6–18.31 V breakdown range. Its low-noise fast-response architecture achieves sub-nanosecond turn-on to limit transients before downstream ICs are damaged.
The device sustains 400 W peak pulse power under 10/1000 μs waveform, with thermal resistance RthJL = 20 K/W to infinite heat sink and MSL Level 1 moisture sensitivity - enabling robust reflow soldering without preconditioning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/5AT | ±5 % VBR tolerance (16.7–18.5 V), 200 W PPP, SMA package (DO-214AC), 1.5 mm height | Lower power rating and looser tolerance; suited for cost-sensitive consumer applications, not automotive-grade surge testing | Select when budget constraints outweigh need for 400 W capability or ±2 % precision |
| 1.5SMC15A | 400 W PPP, ±5 % VBR, SMC package (DO-214AB), 2.6 mm height, 1.5x larger footprint | Higher thermal mass but incompatible with ultra-thin designs; requires larger PCB area and different stencil | Choose when higher thermal dissipation is needed and board space permits larger SMC outline |
Compared with SMAJ15A-E3/5AT and 1.5SMC15A, VTVS15GSMF-M3-18 delivers tighter voltage tolerance and lower profile in a halogen-free, AEC-Q101-capable package - making it optimal for space-constrained, high-reliability automotive and industrial systems requiring repeatable clamping performance.

FAQ
What is the maximum clamping voltage of VTVS15GSMF-M3-18 at its rated peak pulse current?
The VTVS15GSMF-M3-18 has a maximum reverse clamping voltage (VC) of 25 V at its rated peak pulse current of 15.89 A (10/1000 μs waveform). This value is measured under standardized surge conditions and defines the highest voltage the protected circuit will experience during a full-power transient event. The clamping performance is guaranteed across −55 °C to +175 °C operating temperature range, and VTVS15GSMF-M3-18 maintains this specification without derating up to TJ = 175 °C.
Is VTVS15GSMF-M3-18 AEC-Q101 qualified?
VTVS15GSMF-M3-18 itself is not AEC-Q101 qualified; however, the same die and construction are offered in AEC-Q101-qualified versions such as VTVS15GSMF-HM3-18 (halogen-free, AEC-Q101, 10k/reel). The "M3-18" suffix denotes 3 k per 7″ reel, RoHS-compliant, lead (Pb)-free terminations - while AEC-Q101 qualification requires the "H" prefix. VTVS15GSMF-M3-18 shares identical electrical specs and package dimensions with its qualified counterpart.
What is the junction capacitance of VTVS15GSMF-M3-18 and how does it affect signal integrity?
VTVS15GSMF-M3-18 exhibits 684 pF typical junction capacitance at VR = 0 V and f = 1 MHz. This capacitance appears in parallel with the protected line and can attenuate high-frequency signals or distort fast edges. It is appropriate for DC power rails and low-speed interfaces (e.g., I²C, CAN, RS-485), but not recommended for USB 2.0+ data lines or HDMI where sub-10 pF loading is required. For VTVS15GSMF-M3-18, the 684 pF value reflects its optimized energy-handling trade-off rather than signal-speed optimization.
Can VTVS15GSMF-M3-18 be used for bidirectional transient protection?
No - VTVS15GSMF-M3-18 is a unidirectional TVS diode, intended only for protecting circuits with defined polarity (e.g., positive supply rails referenced to ground). Its anode-cathode structure conducts in forward bias and clamps in reverse bias above VBR. For bidirectional protection (e.g., AC lines or differential buses), two VTVS15GSMF-M3-18 devices must be connected in series opposition, or a dedicated bidirectional part like VTVS15BGSF-M3-18 should be selected. Using VTVS15GSMF-M3-18 alone on a bidirectional signal risks forward conduction and damage.
What is the thermal resistance and maximum junction temperature rating of VTVS15GSMF-M3-18?
VTVS15GSMF-M3-18 has a thermal resistance RthJL of 20 K/W (junction-to-lead, mounted on infinite heat sink) and a maximum junction temperature (TJ) rating of +175 °C. This enables reliable operation in under-hood automotive environments and industrial enclosures without active cooling. The 175 °C rating is validated per AEC-Q101 stress tests when used within absolute maximum ratings - and VTVS15GSMF-M3-18 maintains full electrical performance up to this temperature.
