Product details
Overview
VTVS5V0ASMF-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 5.0 V DC power rails and signal lines. It features 6.4–7.0 V reverse breakdown voltage (VBR), 5.0 V maximum stand-off voltage (VRWM), 8.9 V clamping voltage at 42.95 A peak pulse current, ±30 kV IEC 61000-4-2 ESD immunity, and operates from –55 °C to +175 °C junction temperature.
For engineers reviewing the VTVS5V0ASMF-HM3-08 datasheet, VTVS5V0ASMF-HM3-08 pinout, VTVS5V0ASMF-HM3-08 application, or VTVS5V0ASMF-HM3-08 equivalent, key selection criteria include its 400 W 10/1000 μs pulse rating, low 8.9 V clamping performance at rated current, halogen-free SOD-123W-compatible SMF package, AEC-Q101 qualification option, and suitability for automotive infotainment power rail protection.
Technical Context
This device functions as a unidirectional avalanche diode that remains non-conductive below 5.0 V (VRWM) and rapidly clamps transients above ~6.4 V (VBR min). Its low 20 K/W thermal resistance (RthJL) enables effective heat dissipation during 400 W pulses, while its <1 ns response time ensures protection against fast ESD events per IEC 61000-4-2.
The SMF package supports both wave and reflow soldering with peak temperature up to 260 °C, and its 1.08 mm height and 3.9 × 1.9 mm footprint meet space-constrained PCB requirements. The cathode-bar marking and orientation in carrier tape are standardized per Vishay's DO-219AB mechanical drawing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse working voltage before leakage exceeds 5 μA; defines safe operating ceiling for 5 V systems. |
| VBR (min/max) | 6.4 V / 7.0 V at IT = 1 mA - Tight ±5 % tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | 8.9 V at 42.95 A - Clamping voltage under 10/1000 μs surge; limits downstream IC stress to ≤8.9 V during worst-case 400 W event. |
| PPPM | 400 W - Peak pulse power handling capability with 10/1000 μs waveform; sufficient for ISO 16750-2 automotive load dump surges. |
| ESD Rating | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - Full compliance with Level 4 system-level ESD immunity testing. |
| Junction Temp. | –55 °C to +175 °C - Enables deployment in under-hood automotive, industrial motor control, and high-temp power supply environments. |
| Capacitance | 2095 pF at VR = 0 V, f = 1 MHz - Measured value impacts high-speed signal line applicability; suitable for DC/low-frequency power rails only. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Same 5.0 V VRWM, but 400 W rating uses 8.3 × 10.1 mm SMA package; higher RthJA (50 K/W vs. 20 K/W); no AEC-Q101 option. | Less suitable for high-density automotive PCBs due to larger footprint and lower thermal efficiency. | Select VTVS5V0ASMF-HM3-08 when board space, thermal performance, or automotive qualification are critical. |
| 1.5SMC5.0A | Same 5.0 V VRWM, but 1500 W rating in larger SMC package; 10× higher capacitance (≈20,000 pF); not optimized for ESD. | Better for high-energy lightning surges, but excessive capacitance disrupts USB or high-speed signals. | Select VTVS5V0ASMF-HM3-08 for balanced 400 W surge + ±30 kV ESD protection in compact, thermally demanding designs. |
Compared with SMAJ5.0A and 1.5SMC5.0A, VTVS5V0ASMF-HM3-08 delivers superior thermal performance in half the footprint, certified ESD robustness, and automotive-grade qualification-making it optimal for space- and reliability-constrained 5 V rail protection.

FAQ
What is the clamping voltage of VTVS5V0ASMF-HM3-08 under maximum surge conditions?
The VTVS5V0ASMF-HM3-08 has a maximum reverse clamping voltage (VC) of 8.9 V at 42.95 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured and guaranteed per Vishay's datasheet Rev. 2.2, ensuring downstream 5 V ICs experience no more than 8.9 V during worst-case surge events. The low clamping ratio (VC/VRWM ≈ 1.78) reflects efficient transient energy diversion.
Is VTVS5V0ASMF-HM3-08 qualified for automotive use?
Yes, VTVS5V0ASMF-HM3-08 includes the "H" environmental code, indicating AEC-Q101 qualification is available for this part number. The "H" denotes compliance with stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD (HBM), making it suitable for under-hood and cabin automotive applications where reliability is mandated.
What does the "HM3-08" suffix in VTVS5V0ASMF-HM3-08 signify?
In VTVS5V0ASMF-HM3-08, "H" indicates AEC-Q101 qualification, "M" denotes halogen-free material compliance, "3" specifies 3 k per 7″ reel packaging, and "08" identifies the tape-and-reel orientation per Vishay's SMF carrier tape standard. This full ordering code ensures correct procurement of the automotive-grade, RoHS-compliant, and lead-free version in standard production quantities.
Can VTVS5V0ASMF-HM3-08 be used on high-speed signal lines like USB 2.0 data pairs?
No, VTVS5V0ASMF-HM3-08 is not recommended for high-speed signal lines due to its 2095 pF typical junction capacitance at 0 V bias. This capacitance would severely degrade signal integrity on USB 2.0 D+/D– lines (which require <3 pF devices). It is engineered for DC power rails and low-frequency signal lines such as LIN bus or analog sensor supplies where capacitance impact is negligible.
How does the SMF package of VTVS5V0ASMF-HM3-08 compare to SOD-123W?
The SMF (DO-219AB) package of VTVS5V0ASMF-HM3-08 is mechanically and footprint-compatible with SOD-123W, sharing identical 3.9 × 1.9 mm outline and 1.08 mm height. Vishay explicitly states compatibility in the datasheet, enabling drop-in replacement in existing SOD-123W layouts while delivering improved thermal resistance (20 K/W vs. ~35 K/W for SOD-123W) and higher surge robustness.
