Product details
Overview
6DFN16A-M3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DFN3820A package, designed for robust ESD and surge protection of low-voltage signal lines. It features 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), <1.0 μA reverse leakage at VWM, and clamps to 22.5 V at 26.7 A peak pulse current - deployed in sensor interfaces and power rail protection for industrial and automotive electronics.
For engineers reviewing the 6DFN16A-M3/H datasheet, 6DFN16A-M3/H pinout, 6DFN16A-M3/H application, or 6DFN16A-M3/H equivalent, this page delivers verified electrical parameters, package dimensions, AOI-compatible side-wettable flank geometry, thermal resistance values (RθJA = 175 °C/W max), and ESD immunity per IEC 61000-4-2 (±30 kV contact/air).
Technical Context
This unidirectional TVS uses passivated anisotropic rectifier technology optimized for fast response to transients induced by inductive switching or lightning surges. Its DFN3820A footprint provides low-profile mounting (0.88 mm height) with cathode marked by color band and anode connected to heatsink pad.
It operates across -65 °C to +175 °C junction temperature range, meets MSL Level 1 per J-STD-020, and supports automated optical inspection due to side-wettable flanks. Thermal resistance junction-to-mount (RθJM) is 6.5 °C/W max, enabling effective heat dissipation through PCB copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nom) | 16.0 V - precise breakdown threshold ensures reliable triggering before downstream IC damage |
| VWM | 13.6 V - maximum continuous working voltage compatible with 12 V systems |
| IPPM (10/1000 μs) | 26.7 A - peak surge current handling capability validated per Fig. 3 waveform |
| VC @ IPPM | 22.5 V - clamping voltage limits stress on protected circuit during surge event |
| TJ max | +175 °C - high-temperature operation supports under-hood and industrial environments |
| RθJA max | 175 °C/W - thermal resistance defines worst-case junction rise over ambient on standard FR4 |
| ESD Rating | ±30 kV (IEC 61000-4-2) - enables single-device protection against human-body-model discharges |
Pinout & Package
Package: DFN3820A - leadless, low-profile (0.88 mm typical height), side-wettable flanks, matte tin-plated terminals, halogen-free and RoHS-compliant (M3 suffix), polarity indicated by cathode color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Heatsink Pad) | Common cathode return path / thermal interface | Exposed metal pad serves as primary heat sink and electrical anode connection; must be soldered to large copper area |
| Cathode (Marked Terminal) | Transient current sink | Color-banded terminal connects to protected line; conducts surge current to ground/anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) without X-ray, improving manufacturing yield and defect detection |
| MSL Level 1 rating | Allows unlimited floor life and reflow up to 260 °C peak, eliminating bake requirements prior to assembly |
| Unidirectional configuration | Protects DC-biased lines (e.g., 12 V power rails, sensor outputs) without affecting normal forward conduction |
| Junction passivation | Enhances long-term reliability under humidity and bias stress, critical for automotive and medical deployments |
| Low profile (0.88 mm) | Reduces board stack height in space-constrained modules such as ECUs and IoT edge sensors |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ESD events in vehicle ECUs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | DO-214AC package (SMA), higher RθJA (~110 °C/W), 600 W rating, same VBR/VWM tolerance | Requires larger PCB area and lacks side-wettable flanks; not suitable for AOI or ultra-thin designs | Select when legacy SMA footprint compatibility is required and board height >1.5 mm is acceptable |
| SMF16A | SOD-123FL package, lower PPPM (200 W), same VBR range, smaller size but no heatsink pad | Limited to low-energy transients; insufficient for 600 W lightning surge compliance | Choose only for cost-sensitive consumer applications with sub-200 W surge requirements |
Compared with SMAJ16A and SMF16A, the 6DFN16A-M3/H delivers superior thermal performance via its exposed anode pad, enables AOI-capable SMT assembly, and maintains full 600 W surge capability in a 3.95 mm × 2.18 mm footprint - making it optimal for next-generation compact, high-reliability systems.

FAQ
What is the breakdown voltage tolerance for 6DFN16A-M3/H?
The 6DFN16A-M3/H has a breakdown voltage (VBR) tolerance of ±5 %, specified as 15.2 V (min) to 16.8 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise system-level overvoltage margining in 12 V architectures.
Is 6DFN16A-M3/H qualified to AEC-Q101?
Yes, the "H" suffix in 6DFN16A-M3/H denotes AEC-Q101 qualification. This certification confirms that the device has passed stress tests for automotive-grade reliability, including temperature cycling, highly accelerated life testing (HALT), and ESD robustness - making it suitable for under-hood and safety-critical ECU applications.
What does the M3 suffix indicate on 6DFN16A-M3/H?
The M3 suffix on 6DFN16A-M3/H specifies halogen-free, RoHS-compliant construction with Pb-free matte tin terminations, compliant with JESD 201 Class 2 whisker resistance and J-STD-002/JESD 22-B102 solderability standards - ensuring environmental compliance and long-term interconnect reliability in high-volume manufacturing.
How is polarity identified on the 6DFN16A-M3/H package?
Polarity on the 6DFN16A-M3/H is indicated by a color band on the cathode end of the DFN3820A body; the opposite end (unmarked) connects to the exposed anode heatsink pad. This marking aligns with JEDEC-standard orientation and enables correct placement during automated pick-and-place assembly.
What is the maximum junction temperature rating for 6DFN16A-M3/H?
The 6DFN16A-M3/H is rated for a maximum junction temperature (TJ) of +175 °C, supporting operation in high-ambient environments such as engine compartments, industrial motor drives, and enclosed telecom equipment - with derating applied above 25 °C per Figure 2 in the datasheet.
