Product details
Overview
VTVS14ASMF-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 on low-voltage DC lines. It features a 13.8 V stand-off voltage (VRWM), 15.4–17.0 V reverse breakdown voltage (VBR at IT = 1 mA), and clamps to 22.2 V at 17.16 A peak pulse current (10/1000 μs), with ±5 % VBR tolerance and 752 pF typical capacitance at 0 V.
For engineers reviewing the VTVS14ASMF-M3-08 datasheet, VTVS14ASMF-M3-08 pinout, VTVS14ASMF-M3-08 application, or VTVS14ASMF-M3-08 equivalent, this device is selected for robust IEC 61000-4-2 ±30 kV contact/air discharge protection in space-constrained automotive and industrial interfaces where low-profile SOD-123W-compatible packaging and fast clamping response are critical.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 13.8 V working threshold. Its 22.2 V clamping voltage at 17.16 A ensures downstream ICs remain below safe absolute maximum ratings during 10/1000 μs transients.
The SMF package delivers thermal resistance of 20 K/W to leads and supports reflow soldering up to 260 °C. With 175 °C max junction temperature and MSL level 1 rating, it enables high-reliability mounting on PCBs without moisture sensitivity concerns.
Key Specifications

IC Role / Device Role / Timing Role: Low-leakage (0.05 μA at VRWM) clamp on 12 V supply rail feeding sensor ICs. Use Value: Prevents latch-up during 10/1000 μs surges while introducing negligible quiescent current error (<1 nA impact on 16-bit ADC reference). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14A | Same VRWM (14 V) but higher VC = 23.2 V at 17.2 A; SMA package (2.5 mm height vs. 1.08 mm) | Less suitable for ultra-low-profile designs; higher thermal resistance (35 K/W vs. 20 K/W) | Select when legacy SMA footprint reuse is required and board height >2.5 mm is acceptable. |
| TPSMF14A | Identical VRWM and VC specs; same SMF package; ±5 % VBR; halogen-free | Qualified to AEC-Q200 (not AEC-Q101); identical electrical performance and footprint | Prefer for non-safety-critical industrial applications where automotive qualification is not mandated. |
Compared with VTVS14ASMF-M3-08, SMAJ14A trades compactness and thermal performance for broader distributor availability, while TPSMF14A offers identical protection in a non-automotive-qualified variant-enabling cost-optimized sourcing without electrical compromise.

FAQ
What is the maximum clamping voltage of the VTVS14ASMF-M3-08 under standard test conditions?
The VTVS14ASMF-M3-08 exhibits a maximum reverse clamping voltage (VC) of 22.2 V when subjected to a 10/1000 μs peak pulse current of 17.16 A. This value is measured per IEC 61000-4-5 and guarantees that protected circuits remain within safe operating limits during surge events. The VTVS14ASMF-M3-08 maintains this clamping performance across its full −55 °C to +175 °C operating range.
Is the VTVS14ASMF-M3-08 qualified for automotive applications?
Yes, the VTVS14ASMF-M3-08 is AEC-Q101 qualified, confirming its suitability for automotive electronic systems including body control modules, infotainment interfaces, and sensor nodes. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and ESD-ensuring long-term reliability in vehicle environments. The VTVS14ASMF-M3-08 also meets RoHS and halogen-free requirements per Vishay's material compliance standards.
What package type does the VTVS14ASMF-M3-08 use, and is it compatible with automated assembly?
The VTVS14ASMF-M3-08 uses the SMF (DO-219AB) package-a low-profile surface-mount outline measuring 3.9 mm × 1.9 mm × 1.08 mm. It is fully compatible with standard reflow soldering processes, rated for peak temperatures up to 260 °C, and classified as MSL level 1 (unlimited floor life). Its SOD-123W-compatible footprint allows drop-in replacement in existing layouts designed for similar small-outline diodes.
How does the VTVS14ASMF-M3-08 perform under IEC 61000-4-2 ESD testing?
The VTVS14ASMF-M3-08 achieves ±30 kV contact discharge and ±30 kV air discharge per IEC 61000-4-2, making it suitable for protecting high-risk ports such as USB, LIN, and CAN interfaces. Its "Low-Noise" technology ensures sub-nanosecond response time, enabling effective suppression before sensitive ICs experience overstress. The VTVS14ASMF-M3-08 retains full functionality after 10 consecutive discharges at rated levels.
What is the typical junction-to-lead thermal resistance (RthJL) of the VTVS14ASMF-M3-08?
The VTVS14ASMF-M3-08 has a thermal resistance of 20 K/W from junction to lead when mounted on an infinite heat sink. This low RthJL enables efficient heat dissipation during repetitive surge events, supporting reliable operation at elevated ambient temperatures. When soldered to a standard PCB with copper pour, actual thermal performance remains robust-critical for sustained protection in engine bay or industrial control cabinet deployments. The VTVS14ASMF-M3-08 leverages this thermal capability to maintain 400 W peak pulse power rating across its full temperature range.
