Product details
Overview
VTVS25GSMF-HM3-08 from Vishay Semiconductors is a unidirectional 400 W TransZorb® transient voltage suppressor diode in SMF (DO-219AB) package, with 25.2 V maximum stand-off voltage (VRWM), 29.4–30.6 V reverse breakdown voltage (VBR) at 1 mA, and 42 A peak pulse current (IPPM) under 10/1000 μs waveform - deployed for ESD and surge protection on automotive power rails and industrial I/O lines.
For engineers reviewing the VTVS25GSMF-HM3-08 datasheet, VTVS25GSMF-HM3-08 pinout, VTVS25GSMF-HM3-08 application, or VTVS25GSMF-HM3-08 equivalent, key selection criteria include ±2 % VBR tolerance, 42 V clamping voltage (VC) at IPPM, halogen-free SOD-123W-compatible packaging, AEC-Q101 qualification readiness, and ±30 kV IEC 61000-4-2 ESD immunity.
Technical Context
This device operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its precisely specified breakdown range (29.4–30.6 V). Its low dynamic impedance enables rapid clamping to 42 V at 42 A, limiting transient energy delivered to downstream circuitry.
Designed for surface-mount reflow and wave soldering, it features MSL level 1 moisture sensitivity, UL 94 V-0 molding compound, and thermal resistance RthJL = 20 K/W to infinite heat sink - supporting high-reliability operation from –55 °C to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W (10/1000 μs waveform; defines maximum transient energy absorption capability) |
| Stand-off Voltage (VRWM) | 25.2 V (maximum continuous reverse operating voltage before significant leakage) |
| Breakdown Voltage (VBR) | 29.4–30.6 V at IT = 1 mA (±2 % tolerance ensures precise trigger threshold for protection timing) |
| Clamping Voltage (VC) | 42 V at IPPM = 42 A (voltage seen by protected circuit during worst-case surge) |
| ESD Immunity | ±30 kV contact & air discharge per IEC 61000-4-2 (meets automotive and industrial ESD robustness requirements) |
| Junction Temperature Range | –55 °C to +175 °C (supports under-hood automotive and high-temp industrial environments) |
| Capacitance (CD) | 433 pF at VR = 0 V, f = 1 MHz (low enough for DC/low-speed signal line protection without signal integrity impact) |
Pinout & Package
Package: SMF (DO-219AB), low-profile surface-mount case compatible with SOD-123W footprint; dimensions: 3.9 mm × 1.9 mm × 1.08 mm; cathode indicated by bar marking.

| Cathode | Current exit terminal during reverse avalanche; marked with bar | Connected to the line being protected (e.g., 24 V rail or sensor input); clamps transients to safe voltage |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VBR tolerance | Enables tighter system-level overvoltage margin control vs. ±5 % variants, reducing design guardbanding |
| 400 W peak pulse power | Sustains high-energy surges (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure in automotive power networks |
| AEC-Q101 qualification available | Meets stress test requirements for automotive-grade reliability (HTOL, TCT, ESD, etc.) when ordered with "H" code |
| Halogen-free, RoHS-compliant | Complies with environmental regulations and supports lead-free reflow (peak 260 °C) |

Applications
| Automotive Body Control Module (BCM) Power Input | Industrial PLC Digital Input Protection |
|---|---|
|

Use Scenario: Protects battery-backed 3.3 V/5 V rails in wireless sensor nodes exposed to handling ESD and lightning-induced coupling. IC Role / Device Role / Timing Role: Primary overvoltage barrier upstream of LDOs and RF ICs, leveraging low capacitance (433 pF). Use Value: Prevents latch-up or permanent damage to ultra-low-power MCUs without degrading RF performance or sleep current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VTVS25ASMF-HM3-08 | ±5 % VBR tolerance (28.5–31.5 V) vs. ±2 % (29.4–30.6 V); same VRWM, VC, and IPPM | Less precise clamping threshold; suitable where wider voltage margin is acceptable | Select when tighter VBR tolerance is not required and cost optimization is prioritized |
| SMAJ24A-E3/5A | Lower PPPM (400 W same), but higher VC = 38.9 V at 32.4 A; SOD-123 package; no AEC-Q101 option | Higher clamping voltage reduces protection margin; lacks automotive qualification path | Choose for non-automotive, cost-sensitive designs where 38.9 V clamping is sufficient |
Compared with VTVS25GSMF-HM3-08, the ±2 % VBR variant offers superior precision for safety-critical clamping thresholds, while VTVS25ASMF-HM3-08 trades tolerance for cost and SMAJ24A-E3/5A sacrifices automotive compliance and clamping performance for legacy footprint compatibility.

FAQ
What is the clamping voltage of the VTVS25GSMF-HM3-08 at its rated peak pulse current?
The VTVS25GSMF-HM3-08 has a maximum reverse clamping voltage (VC) of 42 V at its rated peak pulse current (IPPM) of 42 A under the 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 VTVS25GSMF-HM3-08 maintains this clamping performance across its full operating temperature range.
Is the VTVS25GSMF-HM3-08 qualified to AEC-Q101?
The VTVS25GSMF-HM3-08 carries the "H" prefix in its ordering code, indicating it is manufactured and tested to meet AEC-Q101 stress requirements for automotive-grade reliability. This includes qualification for high-temperature operating life, temperature cycling, and ESD robustness. The VTVS25GSMF-HM3-08 is intended for use in automotive applications where such qualification is mandatory.
What does the "G" in VTVS25GSMF-HM3-08 signify?
The "G" in VTVS25GSMF-HM3-08 denotes ±2 % tolerance on the reverse breakdown voltage (VBR), distinguishing it from "A"-suffixed variants with ±5 % tolerance. For VTVS25GSMF-HM3-08, VBR is guaranteed between 29.4 V and 30.6 V at IT = 1 mA. This tighter tolerance enables more predictable clamping behavior in precision protection circuits.
Can the VTVS25GSMF-HM3-08 be used in bidirectional configurations?
No - the VTVS25GSMF-HM3-08 is a unidirectional TVS diode, designed for protection on polarity-defined lines such as positive power rails or grounded-signal paths. It conducts only in reverse avalanche mode and must be oriented with cathode toward the protected line. For bidirectional protection (e.g., data lines), a separate symmetric device like VTVS25BxxSMF would be required.
What is the moisture sensitivity level (MSL) of the VTVS25GSMF-HM3-08?
The VTVS25GSMF-HM3-08 is rated MSL level 1 per J-STD-020, meaning it has unlimited floor life at ≤30 °C/85 % RH and may be stored indefinitely without dry-pack requirements. This simplifies handling, assembly planning, and inventory management - especially beneficial for high-mix, low-volume production of automotive and industrial electronics using the VTVS25GSMF-HM3-08.
