Product details
Overview
VTVS36GSMF-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 such as USB, HDMI, and automotive sensor interfaces. It features a 36.0 V stand-off voltage (VRWM), 42.19–43.92 V reverse breakdown voltage (VBR) at 1 mA, 61 A peak pulse current (IPPM), 61 V maximum clamping voltage (VC) at IPPM, and ±30 kV IEC 61000-4-2 ESD immunity.
For engineers reviewing the VTVS36GSMF-M3-18 datasheet, VTVS36GSMF-M3-18 pinout, VTVS36GSMF-M3-18 application, or VTVS36GSMF-M3-18 equivalent, this device delivers precise overvoltage clamping with ±2 % VBR tolerance, low-profile SOD-123W-compatible packaging, halogen-free construction, and AEC-Q101 qualification - critical for automotive infotainment, industrial I/O, and high-reliability embedded power rail protection.
Technical Context
The VTVS36GSMF-M3-18 operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 42.19–43.92 V breakdown threshold, clamping transients to ≤61 V within nanoseconds. Its low 342 pF junction capacitance minimizes signal distortion on high-speed data lines up to 100 Mbps.
Thermal design leverages a 20 K/W junction-to-lead thermal resistance and 175 °C max junction temperature, enabling robust operation under repeated 10/1000 μs surges without derating in standard PCB layouts. The SMF package supports both wave and reflow soldering per J-STD-020 MSL level 1.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5A (Vishay) | Same VRWM (36 V) but ±5 % VBR tolerance (41.4–46.2 V); SMA package (DO-214AC), larger footprint and higher RthJA. | Less precise clamping threshold; suitable for non-critical industrial controls where cost outweighs precision. | Select VTVS36GSMF-M3-18 when ±2 % VBR and low-profile SMF packaging are required for space-constrained designs. |
| TPSMF36A (Littelfuse) | Identical VRWM (36 V), ±2 % VBR, and SMF package; 62 V VC at 6.4 A, 350 pF capacitance, AEC-Q101 qualified. | Nearly identical electrical specs; minor variation in clamping consistency and moisture sensitivity level (MSL 1 vs. MSL 2a). | Choose VTVS36GSMF-M3-18 for guaranteed Vishay TransZorb® process consistency and documented halogen-free compliance per JESD201 class 2. |
Compared with SMAJ36A-E3/5A and TPSMF36A, the VTVS36GSMF-M3-18 offers tighter VBR tolerance than the former and superior moisture robustness (MSL level 1) versus the latter - making it optimal for high-volume automotive and medical-grade assemblies requiring zero reflow defects.

FAQ
What is the clamping voltage of the VTVS36GSMF-M3-18 at its rated peak pulse current?
The VTVS36GSMF-M3-18 has a maximum reverse clamping voltage (VC) of 61 V at its rated peak pulse current (IPPM) of 6.43 A under a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and ensures downstream circuitry remains within safe operating limits during surge events. The VTVS36GSMF-M3-18 achieves this clamping performance while maintaining low leakage (<0.05 μA at VRWM) and stable thermal behavior up to 175 °C junction temperature.
Is the VTVS36GSMF-M3-18 suitable for automotive applications?
Yes, the VTVS36GSMF-M3-18 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control modules, infotainment systems, and ADAS sensor interfaces. Its −55 °C to +175 °C operating range, ±30 kV IEC 61000-4-2 ESD rating, and halogen-free construction meet stringent automotive reliability and environmental compliance requirements. The VTVS36GSMF-M3-18 is also tested for mechanical shock, vibration, and humidity resistance per AEC-Q101 stress test conditions.
How does the ±2 % VBR tolerance of the VTVS36GSMF-M3-18 improve system-level protection design?
The ±2 % VBR tolerance of the VTVS36GSMF-M3-18 enables tighter coordination with upstream fuses and downstream IC absolute maximum ratings, reducing design margin uncertainty and allowing smaller, more efficient protection schemes. Unlike ±5 % tolerance variants, the VTVS36GSMF-M3-18 guarantees breakdown occurs between 42.19 V and 43.92 V - ensuring consistent clamping onset across production batches and eliminating unexpected conduction during normal 36 V rail operation. This precision directly enhances system robustness in safety-critical applications.
What is the thermal resistance and maximum junction temperature of the VTVS36GSMF-M3-18?
The VTVS36GSMF-M3-18 has a junction-to-lead thermal resistance (RthJL) of 20 K/W when mounted on an infinite heat sink, and a maximum junction temperature (TJ) of +175 °C. These specifications allow the device to dissipate 400 W peak pulse power repeatedly without thermal runaway, provided PCB copper area and solder joint integrity meet Vishay's recommended footprint guidelines. The VTVS36GSMF-M3-18 maintains full electrical performance across its entire −55 °C to +175 °C operating range, with no derating required below 125 °C ambient.
Can the VTVS36GSMF-M3-18 be used in high-speed data lines like HDMI or USB 3.0?
The VTVS36GSMF-M3-18 is optimized for USB 2.0 (480 Mbps) and automotive serial buses (e.g., LIN, CAN FD) with its 342 pF junction capacitance - low enough to avoid signal integrity issues at those speeds. However, it is not recommended for USB 3.0 (5 Gbps) or HDMI 2.0 (18 Gbps), where sub-1 pF capacitance is typically required. For those interfaces, lower-capacitance TVS arrays or specialized ESD protection ICs should be selected. The VTVS36GSMF-M3-18 remains ideal for protecting associated power and sideband signals in those systems.
