Product details
Overview
6DFN13A-M3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in a DFN3820A package, designed for robust ESD and surge protection on signal/power lines. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 33.0 A peak pulse current, and clamps to 18.2 V at rated surge. It is deployed in sensor interface protection for industrial automation systems.
For engineers reviewing the 6DFN13A-M3/H datasheet, 6DFN13A-M3/H pinout, 6DFN13A-M3/H application, or 6DFN13A-M3/H equivalent, key selection criteria include unidirectional clamping behavior, low-profile DFN3820A footprint with side-wettable flanks for AOI, MSL Level 1 rating, and 30 kV IEC 61000-4-2 ESD immunity - critical for high-reliability embedded sensor nodes and automotive-grade peripherals.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for fast response to transients induced by inductive switching and lightning surges. Its unidirectional configuration provides precise reverse-biased clamping while maintaining low leakage (<2.0 μA at VWM) and stable thermal performance up to TJ = 175 °C.
The DFN3820A package enables high-density PCB layouts with thermal resistance RθJA = 140 °C/W (typ.) and RθJM = 5 °C/W (typ.), supporting efficient heat transfer to the mounting pad. Its polarity marking (cathode band) and matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 / 13.0 / 13.7 V - ensures reliable triggering above system operating voltage with ±5% tolerance |
| VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 2.0 μA, compatible with 12 V rail interfaces |
| PPPM | 600 W (10/1000 μs) - sustains high-energy surges without failure in industrial I/O protection |
| IPPM | 33.0 A - peak surge current handling capability verified per Fig. 3 waveform |

| TJ max | +175 °C - supports operation in under-hood or enclosed industrial enclosures without derating |
| ESD immunity | ±30 kV (IEC 61000-4-2 contact/air) - eliminates need for secondary ESD stages in sensor front-ends |
Pinout & Package
Package: DFN3820A - leadless, low-profile (0.88 mm typical height), side-wettable flanks for automated optical inspection and reflow compatibility. Molding compound meets UL 94 V-0; terminals are matte tin-plated per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | DO-214AC (SMA) package; higher RθJA = 40 °C/W; 13.3 V VBR; 600 W rating | Through-hole or larger SMT footprint required; less suitable for ultra-dense layouts | Choose SMAJ13A only when board space allows larger package and AOI is not required |
| SMCJ13A | DO-214AB (SMC) package; 13.3 V VBR; 1500 W rating; RθJA = 25 °C/W | Higher power handling but 3× larger footprint; no side-wettable flanks | Use SMCJ13A where surge energy exceeds 600 W or thermal dissipation demands larger copper area |
Compared with SMAJ13A and SMCJ13A, the 6DFN13A-M3/H delivers identical clamping performance in a 3.95 mm × 2.18 mm DFN3820A package with AOI-compatible side-wettable flanks and AEC-Q101 qualification - enabling miniaturized, automotive-grade, and high-yield production designs without layout compromise.

FAQ
What is the exact breakdown voltage range for 6DFN13A-M3/H?
The 6DFN13A-M3/H has a guaranteed breakdown voltage (VBR) range of 12.4 V (min) to 13.7 V (max) at 1.0 mA test current, with a nominal value of 13.0 V. This ±5% tolerance is specified per the Vishay datasheet revision 10-Nov-2023 (Document Number: 98464), ensuring predictable clamping onset across temperature and production lots. The 6DFN13A-M3/H maintains this specification under standard JEDEC test conditions.
Is 6DFN13A-M3/H qualified for automotive applications?
Yes, the "H" suffix in 6DFN13A-M3/H denotes AEC-Q101 qualification, confirming full compliance with stress testing requirements for automotive discrete semiconductors, including temperature cycling, high-temperature reverse bias (HTRB), and ESD. This makes the 6DFN13A-M3/H suitable for engine control, ADAS sensors, and body electronics where reliability under harsh conditions is essential.
What does the "M3" suffix mean in 6DFN13A-M3/H?
The "M3" suffix indicates halogen-free, RoHS-compliant construction with Pb-free matte tin plating on terminals, meeting JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards. It also confirms industrial-grade reliability and UL 94 V-0 flammability rating for the molding compound - all verified for the 6DFN13A-M3/H per Vishay's material categorization documentation.
How is polarity identified on the 6DFN13A-M3/H package?
Polarity is marked by a color band on the cathode end of the 6DFN13A-M3/H DFN3820A package; the opposite end (unmarked) is the anode, which corresponds to the exposed metal heatsink pad. This marking aligns with JEDEC-standard DFN polarity conventions and is visible under AOI inspection due to side-wettable flanks - critical for correct placement during automated assembly of the 6DFN13A-M3/H.
What is the thermal resistance from junction to mount (RθJM) for 6DFN13A-M3/H?
The 6DFN13A-M3/H has a typical junction-to-mount thermal resistance (RθJM) of 5 °C/W, measured per JEDEC 51-14 using the Transient Dual Interface Method (TDIM). This low value reflects efficient heat conduction from the silicon die through the exposed anode pad into the PCB copper, enabling sustained 600 W surge handling without exceeding TJ = 175 °C when properly mounted - a key design parameter for the 6DFN13A-M3/H.
