Product details
Overview
VTVS36GSMF-HM3-08 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 DC lines. 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) under 10/1000 μs waveform, and clamps to ≤61 V at rated current - ideal for protecting USB, HDMI, and automotive sensor interfaces.
For engineers reviewing the VTVS36GSMF-HM3-08 datasheet, VTVS36GSMF-HM3-08 pinout, VTVS36GSMF-HM3-08 application, or VTVS36GSMF-HM3-08 equivalent, this device delivers ±2 % VBR tolerance, ±30 kV IEC 61000-4-2 ESD immunity, halogen-free construction, and AEC-Q101 qualification - critical for automotive infotainment and ADAS power rail protection.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, triggered when reverse voltage exceeds its 42.19–43.92 V VBR range. Its low dynamic impedance ensures rapid response (<1 ns) and stable clamping at 61 V (VC) under 61 A transient stress.
The SMF (DO-219AB) package enables high thermal dissipation (RthJL = 20 K/W) and supports wave/reflow soldering per J-STD-020 MSL level 1. Junction temperature range spans −55 °C to +175 °C, supporting under-hood automotive deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRWM) | 36.0 V - maximum continuous reverse operating voltage before significant leakage |
| Breakdown Voltage (VBR) | 42.19–43.92 V at IT = 1 mA - tight ±2 % tolerance enables precise overvoltage threshold setting |
| Clamping Voltage (VC) | ≤61 V at IPPM = 61 A (10/1000 μs) - limits downstream IC voltage stress during surge events |
| Peak Pulse Power (PPP) | 400 W - sustains standardized lightning/surge transients without failure |
| ESD Rating | ±30 kV contact & air discharge (IEC 61000-4-2) - meets automotive ESD immunity requirements |
| Junction Temperature Range | −55 °C to +175 °C - qualified for engine control unit and transmission control module environments |
| Capacitance (CD) | 342 pF at VR = 0 V, f = 1 MHz - low enough for USB 2.0 signal integrity, not suitable for USB 3.x or PCIe |
Pinout & Package
SMF (DO-219AB) package: low-profile surface-mount outline with cathode marking bar; dimensions 3.9 × 1.9 × 1.08 mm; compatible with SOD-123W footprint.

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-HM3-08 | ±5 % VBR tolerance (40.9–45.2 V) vs. ±2 % for VTVS36GSMF-HM3-08 | Less precise clamping threshold; acceptable where system margin >1.5 V | Select when cost sensitivity outweighs need for tight VBR control in non-safety-critical circuits |
| SMAJ36A-E3/57T | Same VRWM (36 V) but higher VC (64.5 V at 61.5 A); SMA package (DO-214AC), larger footprint | Lower power density (400 W in larger SMA vs. SMF); less suitable for space-constrained automotive PCBs | Choose if existing SMA footprint reuse is prioritized over board area savings and thermal performance |
Compared with VTVS36ASMF-HM3-08 and SMAJ36A-E3/57T, VTVS36GSMF-HM3-08 offers superior VBR precision and smaller SMF footprint - enabling tighter layout margins and improved thermal response in high-reliability automotive modules.

FAQ
What is the clamping voltage of VTVS36GSMF-HM3-08 at its rated peak pulse current?
The VTVS36GSMF-HM3-08 clamps to a maximum of 61 V when subjected to its rated 61 A peak pulse current (10/1000 μs waveform). This value is measured per IEC 61000-4-5 and ensures protected circuitry remains below typical 70 V absolute maximum ratings of automotive transceivers and microcontrollers. The VTVS36GSMF-HM3-08 achieves this with low dynamic impedance and stable avalanche characteristics across its full operating temperature range.
Is VTVS36GSMF-HM3-08 qualified for automotive use?
Yes, VTVS36GSMF-HM3-08 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114. Its −55 °C to +175 °C junction temperature range and halogen-free construction meet OEM requirements for powertrain and body electronics. The VTVS36GSMF-HM3-08 is explicitly listed in Vishay's AEC-Q101 certified product portfolio for the eSMP® SMF family.
How does the ±2 % VBR tolerance of VTVS36GSMF-HM3-08 compare to standard ±5 % TVS diodes?
The ±2 % VBR tolerance (42.19–43.92 V) of VTVS36GSMF-HM3-08 provides tighter control over the clamping initiation point versus ±5 % variants like VTVS36ASMF-HM3-08 (40.9–45.2 V). This reduces design margin uncertainty, allowing safer operation closer to downstream IC absolute maximum ratings. In practice, the VTVS36GSMF-HM3-08 enables more aggressive system-level overvoltage protection schemes without compromising reliability.
Can VTVS36GSMF-HM3-08 be used in USB 2.0 data line protection?
Yes, VTVS36GSMF-HM3-08 is suitable for USB 2.0 D+/D− line protection due to its 342 pF capacitance at 0 V bias and fast response time. While not optimized for high-speed protocols like USB 3.x, its clamping performance and ±30 kV IEC 61000-4-2 rating make it effective for ESD suppression in automotive infotainment USB ports. Layout must maintain controlled impedance and minimize stub length to preserve signal integrity - a key consideration when deploying the VTVS36GSMF-HM3-08 in high-frequency interfaces.
What is the thermal resistance and maximum power dissipation capability of VTVS36GSMF-HM3-08?
The VTVS36GSMF-HM3-08 has a junction-to-lead thermal resistance (RthJL) of 20 K/W when mounted on an infinite heat sink, enabling efficient transient power dissipation. Its 400 W peak pulse power rating applies to the 10/1000 μs waveform, and steady-state power handling is limited by ambient conditions and PCB copper area. For sustained surge events, the VTVS36GSMF-HM3-08 relies on short-duration energy absorption rather than continuous dissipation - consistent with TVS diode operational principles.
