Product details
Overview
VTVS23ASMF-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 22.6 V maximum stand-off voltage (VRWM), 25.7–28.4 V reverse breakdown voltage (VBR) at 1 mA, 38 A peak pulse current (IPPM), 38 V maximum clamping voltage (VC) at IPPM, and ±30 kV IEC 61000-4-2 ESD immunity - deployed in automotive infotainment power rails.
For engineers reviewing the VTVS23ASMF-HM3-08 datasheet, VTVS23ASMF-HM3-08 pinout, VTVS23ASMF-HM3-08 application, or VTVS23ASMF-HM3-08 equivalent, this page delivers verified electrical specs, SMF package dimensions, clamping performance under 10/1000 μs transients, halogen-free compliance, and AEC-Q101 qualification status - critical for automotive-grade board-level surge hardening.
Technical Context
This TVS diode operates as a unidirectional shunt protector with avalanche breakdown behavior, triggered when reverse voltage exceeds VRWM = 22.6 V. Its low clamping ratio (VC/VBR ≈ 1.45) ensures minimal overvoltage stress on downstream ICs during 10/1000 μs surges up to 400 W.
The device uses "Low-Noise" fast-response silicon technology with <1 ns response time, enabling effective suppression of ESD events (±30 kV contact/air) and repetitive transients in 12 V automotive systems. Its DO-219AB footprint supports high-density PCB layouts and is compatible with SOD-123W, SOD-123F, and SOD-123FL land patterns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform); sustains repeated surge events without degradation in automotive power line applications |
| Stand-off Voltage (VRWM) | 22.6 V max; blocks normal 12–24 V system operation while remaining non-conductive until transient onset |
| Breakdown Voltage (VBR) | 25.7–28.4 V at IT = 1 mA; tight ±5 % tolerance ensures predictable turn-on across temperature and production lots |
| Clamping Voltage (VC) | 38 V at IPPM = 38 A; limits voltage seen by protected ICs to safe levels during worst-case surge conditions |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2; eliminates need for additional ESD stages in USB, CAN, or sensor interfaces |
| Junction Temp Range | −55 °C to +175 °C; supports under-hood deployment in engine control units and ADAS modules |
| Capacitance (CD) | 480 pF at VR = 0 V, f = 1 MHz; suitable for DC power rail protection where signal integrity is not compromised |
Pinout & Package
SMF (DO-219AB) low-profile surface-mount package: 3.9 mm × 1.9 mm × 1.08 mm body, halogen-free molding compound, MSL level 1, reflow-compatible (peak 260 °C). Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground; completes clamping path during reverse transient events |
| Cathode | Protected line input | Connected to line being protected (e.g., 12 V supply rail); conducts avalanche current to ground when VR > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, mechanical shock, and humidity testing per JESD22 standards |
| Halogen-free & RoHS-compliant | Meets automotive environmental requirements and enables compliance with ELV and REACH directives |
| Wave and reflow solderable | Compatible with standard SMT assembly processes including lead-free reflow profiles up to 260 °C peak |
| Low-profile SMF package | 1.08 mm height enables use in space-constrained modules such as telematics control units and camera ECUs |
| "Low-Noise" fast response | Sub-nanosecond turn-on minimizes voltage overshoot during ESD strikes, protecting sensitive analog front-ends |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5A | Higher VRWM (24 V), lower PPPM (400 W same), but larger SMA package (4.5 mm × 2.7 mm × 2.3 mm) | Less suitable for ultra-thin modules due to 2.3 mm height; requires larger pad layout | Select when legacy SMA footprint exists and thermal margin permits higher RthJA |
| TPSMF24A | Same SMF package, tighter VBR tolerance (±2 %), but lower clamping ratio (VC = 36.6 V at IPPM) | Better precision for systems requiring strict voltage ceiling; slightly improved energy handling at same VC | Prefer for next-gen designs demanding tighter parametric control and AEC-Q101 consistency |
Compared with SMAJ24A-E3/5A and TPSMF24A, VTVS23ASMF-HM3-08 offers optimal balance of compact DO-219AB footprint, automotive qualification, and proven clamping performance at 22.6 V standoff - making it ideal for new 12 V domain controller designs where board space and qualification rigor are primary constraints.

FAQ
What is the maximum clamping voltage of the VTVS23ASMF-HM3-08 under a 10/1000 μs surge?
The VTVS23ASMF-HM3-08 has a maximum reverse clamping voltage (VC) of 38 V at its rated peak pulse current (IPPM) of 38 A under 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 VTVS23ASMF-HM3-08 maintains this clamping performance across its full operating temperature range (−55 °C to +175 °C).
Is the VTVS23ASMF-HM3-08 qualified to AEC-Q101?
Yes, the VTVS23ASMF-HM3-08 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control, body electronics, and ADAS systems. Qualification covers stress tests such as temperature cycling, high-temperature operating life, and ESD robustness. The VTVS23ASMF-HM3-08 meets all requirements specified in the AEC-Q101-004 standard for discrete semiconductors.
What does the "HM3-08" suffix indicate in VTVS23ASMF-HM3-08?
The "HM3-08" suffix denotes halogen-free (H), lead-free termination with tin plating (M), 3 k per 7″ reel packaging (3), and tape-and-reel format optimized for automated SMT placement (08). This matches Vishay's standardized ordering code structure defined in Document 85891, confirming RoHS compliance, MSL level 1 handling, and compatibility with standard pick-and-place equipment.
Can the VTVS23ASMF-HM3-08 be used in bidirectional configurations?
No, the VTVS23ASMF-HM3-08 is a unidirectional TVS diode and must be used with correct polarity: cathode toward the protected line, anode to ground. Bidirectional protection requires either two unidirectional devices in series opposition or a dedicated bidirectional part like VTVS23BSMF-HM3-08. Using VTVS23ASMF-HM3-08 in reverse bias beyond its VRWM risks premature conduction in normal operation.
What is the typical junction-to-lead thermal resistance (RthJL) of the VTVS23ASMF-HM3-08?
The VTVS23ASMF-HM3-08 has a thermal resistance of 20 K/W from junction to lead when mounted on an infinite heat sink. This value enables accurate thermal modeling of power dissipation during transient events and informs heatsinking decisions in high-duty-cycle applications. The low RthJL contributes to the device's ability to sustain 400 W peak pulse power without thermal runaway.
