Product details
Overview
VTVS36GSMF-HM3-18 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, with 36.0 V stand-off voltage (VRWM), ±2 % breakdown voltage tolerance, and 61 A peak pulse current (IPPM) under 10/1000 μs waveform - designed for ESD and surge protection of automotive power rails and industrial I/O interfaces.
For engineers reviewing the VTVS36GSMF-HM3-18 datasheet, VTVS36GSMF-HM3-18 pinout, VTVS36GSMF-HM3-18 application, or VTVS36GSMF-HM3-18 equivalent, this device delivers precise clamping at 61 V (VC) with 342 pF capacitance at 0 V, AEC-Q101 qualification, and halogen-free construction - critical for robust front-end protection in CAN, LIN, and sensor signal conditioning circuits.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 42.19–43.92 V breakdown range (VBR) at 1 mA test current. Its low thermal resistance (20 K/W junction-to-lead) enables reliable 400 W peak pulse power dissipation under standardized 10/1000 μs transients.
It achieves ±30 kV ESD immunity per IEC 61000-4-2 (contact and air discharge), with fast response time enabled by "Low-Noise" silicon technology. The SMF package supports wave and reflow soldering, complies with MSL level 1, and matches SOD-123W/SOD-123F footprints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W - sustains high-energy transients without failure under 10/1000 μs waveform |
| Stand-off Voltage (VRWM) | 36.0 V - maximum continuous reverse working voltage before significant leakage |
| Breakdown Voltage (VBR) | 42.19–43.92 V at IT = 1 mA - tight ±2 % tolerance ensures predictable clamping onset |
| Clamping Voltage (VC) | 61 V at IPPM = 6.43 A - limits downstream voltage during surge to protect 36 V-rated ICs |
| Capacitance (CD) | 342 pF at VR = 0 V, f = 1 MHz - low enough for <1 Mbps CAN/LIN bus integrity |
| ESD Rating | ±30 kV contact / ±30 kV air discharge - exceeds IEC 61000-4-2 Level 4 immunity requirements |
| Junction Temperature Range | −55 °C to +175 °C - supports under-hood automotive and industrial ambient conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VTVS36ASMF-HM3-18 | ±5 % VBR tolerance (40.9–45.2 V) vs. ±2 % for VTVS36GSMF-HM3-18 | Less precise clamping onset; suitable where wider voltage margin is acceptable | Select when cost sensitivity outweighs need for tight VBR control in safety-critical sensing paths |
| SMAJ36A-E3/5AT | Same VRWM (36 V), but 400 W rating with ±5 % VBR and SMA package (DO-214AC) | Larger footprint (4.5 mm × 2.7 mm) and higher thermal resistance (35 K/W) | Choose only if legacy SMA layout exists; VTVS36GSMF-HM3-18 offers superior thermal performance and space savings |
Compared with VTVS36ASMF-HM3-18 and SMAJ36A-E3/5AT, VTVS36GSMF-HM3-18 provides tighter voltage tolerance, lower profile, and better thermal dissipation - making it optimal for new automotive designs requiring AEC-Q101 compliance and compact board area.

FAQ
What is the clamping voltage of the VTVS36GSMF-HM3-18 under peak pulse conditions?
The VTVS36GSMF-HM3-18 has a maximum reverse clamping voltage (VC) of 61 V at its rated peak pulse current of 6.43 A (10/1000 μs waveform). This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The VTVS36GSMF-HM3-18 maintains this clamping performance across its full operating temperature range.
Is the VTVS36GSMF-HM3-18 qualified for automotive applications?
Yes, the VTVS36GSMF-HM3-18 is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature reverse bias, temperature cycling, and ESD robustness required for automotive electronic control units. Its −55 °C to +175 °C junction temperature range and halogen-free construction further support under-hood deployment. The VTVS36GSMF-HM3-18 meets these requirements as documented in Vishay's official qualification report.
How does the ±2 % breakdown voltage tolerance of VTVS36GSMF-HM3-18 compare to standard ±5 % TVS diodes?
The ±2 % VBR tolerance of VTVS36GSMF-HM3-18 (42.19–43.92 V) provides significantly tighter control over clamping onset versus ±5 % variants like VTVS36ASMF-HM3-18 (40.9–45.2 V). This reduces design uncertainty in voltage-margin-critical applications such as ADC input protection or regulated 36 V rail supervision. The VTVS36GSMF-HM3-18 achieves this via enhanced process control during silicon fabrication.
What is the package type and mounting compatibility of VTVS36GSMF-HM3-18?
The VTVS36GSMF-HM3-18 uses the SMF (DO-219AB) package - a low-profile surface-mount outline measuring 3.9 mm × 1.9 mm × 1.08 mm. It is compatible with standard wave and reflow soldering processes (peak temp ≤ 260 °C) and matches the footprint of SOD-123W, SOD-123F, and SOD-123FL packages. The VTVS36GSMF-HM3-18 features a cathode bar marking and MSL level 1 moisture sensitivity rating.
Does the VTVS36GSMF-HM3-18 meet IEC 61000-4-2 ESD immunity requirements?
Yes, the VTVS36GSMF-HM3-18 is rated for ±30 kV contact discharge and ±30 kV air discharge per IEC 61000-4-2, exceeding Level 4 (the highest severity class). This performance is achieved through optimized junction design and "Low-Noise" silicon technology enabling sub-nanosecond response. The VTVS36GSMF-HM3-18 delivers this ESD protection while maintaining low leakage (<0.05 μA at VRWM) and stable clamping behavior.
