Product details
Overview
VTVS15GSMF-HM3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, with 15.1 V maximum stand-off voltage (VRWM), 17.60–18.31 V reverse breakdown voltage (VBR) at 1 mA, and 25 V maximum clamping voltage (VC) at 15.89 A peak pulse current (IPPM); used for ESD and surge protection on low-voltage DC power rails and I/O lines in automotive infotainment and industrial control interfaces.
For engineers reviewing the VTVS15GSMF-HM3-18 datasheet, VTVS15GSMF-HM3-18 pinout, VTVS15GSMF-HM3-18 application, or VTVS15GSMF-HM3-18 equivalent, key selection criteria include ±2 % VBR tolerance, 1.08 mm height low-profile SOD-123W-compatible footprint, ±30 kV IEC 61000-4-2 ESD immunity, and halogen-free, AEC-Q101-qualified construction for high-reliability embedded systems.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its precisely specified 17.60–18.31 V breakdown range (±2 % tolerance), then clamping transients to ≤25 V at 15.89 A (10/1000 μs waveform). Its low 684 pF junction capacitance enables use on signal lines up to ~100 MHz without significant attenuation.
Thermal resistance of 20 K/W (junction-to-lead, infinite heat sink) supports sustained operation up to +175 °C junction temperature. The SMF package meets J-STD-020 MSL level 1 and withstands peak reflow temperatures up to 260 °C, enabling compatibility with standard automated assembly processes.

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-E3/57T | ±5 % VBR tolerance (16.7–18.5 V), higher 750 pF capacitance, same 400 W rating | Less precise clamping onset; higher capacitance limits use on >20 MHz signals | Lower-cost option where ±5 % VBR and relaxed signal bandwidth are acceptable |
| 1.5SMC15A | DO-214AB (SMC) package (7.1 × 6.2 × 2.6 mm), 3× larger footprint, same electrical specs | Requires PCB layout change; better thermal dissipation but incompatible with space-constrained designs | Preferred when higher thermal mass is needed for repetitive surge duty cycles |
Compared with SMAJ15A-E3/57T and 1.5SMC15A, VTVS15GSMF-HM3-18 offers tighter ±2 % VBR control and 30 % lower capacitance in a 60 % smaller footprint-making it optimal for modern automotive and portable medical PCBs where precision, speed, and miniaturization are critical.

FAQ
What is the clamping voltage of VTVS15GSMF-HM3-18 at its rated peak pulse current?
The VTVS15GSMF-HM3-18 has a maximum reverse clamping voltage (VC) of 25 V at its rated peak pulse current (IPPM) of 15.89 A, measured using a 10/1000 μs waveform. This value ensures protected circuits remain below critical voltage thresholds during surge events. The VTVS15GSMF-HM3-18 achieves this performance while maintaining low leakage (<0.05 μA at 15.1 V) in normal operation.
Is VTVS15GSMF-HM3-18 qualified for automotive applications?
Yes, VTVS15GSMF-HM3-18 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD robustness per automotive standards. It is rated for operation from −55 °C to +175 °C junction temperature, making it suitable for engine bay, body control, and infotainment modules. The VTVS15GSMF-HM3-18 also complies with IEC 61000-4-2 (±30 kV) and ISO 7637-2 surge immunity requirements.
What does the "HM3" suffix indicate in VTVS15GSMF-HM3-18?
The "HM3" suffix in VTVS15GSMF-HM3-18 denotes halogen-free construction (H), lead (Pb)-free terminations with tin plating (M), and packaging in a 3 k per 7″ reel (3). The "-18" indicates tape-and-reel packaging with 8 mm carrier tape width and EIA-481-2 compliance. This full ordering code confirms RoHS compliance, halogen-free molding compound, and standard SMT handling compatibility for VTVS15GSMF-HM3-18.
Can VTVS15GSMF-HM3-18 be used for bidirectional protection?
No, VTVS15GSMF-HM3-18 is a unidirectional TVS diode, designed for protection on DC rails referenced to ground. For bidirectional (AC or floating) signal lines, two VTVS15GSMF-HM3-18 devices must be connected in series opposition (anode-to-anode or cathode-to-cathode). Its datasheet specifies polarity as unidirectional, and its breakdown behavior is defined only for reverse-biased operation. Using a single VTVS15GSMF-HM3-18 in bidirectional mode would leave one polarity unprotected.
How does the 684 pF capacitance of VTVS15GSMF-HM3-18 affect high-speed signal lines?
The 684 pF junction capacitance of VTVS15GSMF-HM3-18 is measured at 0 V bias and 1 MHz; it decreases significantly at operating VRWM (15.1 V), typically falling below 100 pF. This enables use on moderate-speed digital lines such as CAN (1 Mbps), LIN (20 kbps), and analog sensor outputs without measurable rise-time degradation or signal reflection. For USB 2.0 or HDMI, lower-capacitance alternatives are recommended-but VTVS15GSMF-HM3-18 remains appropriate for most industrial and automotive serial interfaces.
