Product details
Overview
VTVS25GSMF-M3-08 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 25.2 V DC power rails and signal lines. It delivers 9.35 A peak pulse current (10/1000 μs), clamps to 42 V max at rated current, and features ±2 % breakdown voltage tolerance (29.4–30.6 V at 1 mA), with IEC 61000-4-2 ±30 kV contact/air discharge compliance.
For engineers reviewing the VTVS25GSMF-M3-08 datasheet, VTVS25GSMF-M3-08 pinout, VTVS25GSMF-M3-08 application, or VTVS25GSMF-M3-08 equivalent, this device is selected for high-reliability automotive infotainment power inputs, industrial sensor interfaces, and USB-C VBUS line protection where precise 25 V standoff, low clamping overshoot, and AEC-Q101 qualification are required.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 29.4–30.6 V breakdown range. Its 42 V maximum clamping voltage at 9.35 A ensures downstream ICs see limited overvoltage during 10/1000 μs transients, while 433 pF capacitance at 0 V enables use on moderate-speed data lines without signal integrity degradation.
The SMF (DO-219AB) package supports wave and reflow soldering, with MSL level 1 rating and peak temperature tolerance up to 260 °C. Junction temperature range spans −55 °C to +175 °C, supporting under-hood automotive and industrial environments where thermal robustness is critical.

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-E3/57T | 24 V VRWM, ±5 % VBR (26.7–29.7 V), 400 W, SMA package (larger footprint, higher RthJA) | Less precise standoff; requires PCB area increase; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and tight voltage tolerance. |
| TPSMD24A | 24 V VRWM, ±5 % VBR, 400 W, DO-214AB package, 550 pF capacitance | Higher capacitance limits use on >10 Mbps data lines; no AEC-Q101 documentation found | Choose for legacy designs using SMA/SMB footprints where 550 pF is acceptable and automotive validation is not required. |
Compared with SMAJ24A-E3/57T and TPSMD24A, VTVS25GSMF-M3-08 provides tighter ±2 % breakdown tolerance, AEC-Q101 qualification, lower 433 pF capacitance, and a smaller SMF footprint-making it optimal for space-constrained, high-reliability 24 V system protection where voltage precision and thermal performance matter.

FAQ
What is the maximum clamping voltage of VTVS25GSMF-M3-08 under standard test conditions?
The VTVS25GSMF-M3-08 has a maximum reverse clamping voltage (VC) of 42 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 9.35 A. This value is measured per IEC 61000-4-5 and ensures protected circuits remain within safe operating limits during surge events. The VTVS25GSMF-M3-08 datasheet specifies this parameter under standardized thermal conditions at Tamb = 25 °C.
Is VTVS25GSMF-M3-08 qualified for automotive applications?
Yes, VTVS25GSMF-M3-08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life required for automotive electronic components. This qualification confirms its suitability for under-hood and cabin applications such as infotainment power supplies and ADAS sensor interfaces. The VTVS25GSMF-M3-08 meets these standards as documented in Vishay's official qualification reports.
What does the "G" in VTVS25GSMF-M3-08 indicate?
The "G" in VTVS25GSMF-M3-08 denotes ±2 % tolerance on the reverse breakdown voltage (VBR), distinguishing it from "A"-suffix variants with ±5 % tolerance. For VTVS25GSMF-M3-08, this means guaranteed VBR between 29.4 V and 30.6 V at 1 mA test current. This tighter tolerance improves design predictability in systems where precise clamping onset is critical. The VTVS25GSMF-M3-08 marking code "9C2" also reflects this grade.
Can VTVS25GSMF-M3-08 be used in bidirectional protection configurations?
No, VTVS25GSMF-M3-08 is a unidirectional TVS diode and must be used only in polarity-aware configurations-cathode toward the protected line, anode to ground. It does not provide symmetrical clamping for AC or bidirectional transients. For bidirectional protection, two VTVS25GSMF-M3-08 devices in series opposition or a dedicated bidirectional part like VTVS25BGSF-M3-08 would be required. The VTVS25GSMF-M3-08 datasheet explicitly specifies unidirectional polarity.
What is the moisture sensitivity level (MSL) rating for VTVS25GSMF-M3-08?
VTVS25GSMF-M3-08 has a moisture sensitivity level (MSL) rating of level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without baking prior to reflow soldering. This eliminates handling constraints during manufacturing and supports standard SMT assembly processes. The VTVS25GSMF-M3-08 package (SMF/DO-219AB) uses halogen-free molding compound certified to UL 94 V-0 flammability rating.
