Product details
Overview
6DFN30A-M3/H from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 30 V nominal breakdown voltage (VBR = 28.5–31.5 V), 25.6 V stand-off voltage (VWM), 41.4 V max clamping voltage at 14.5 A peak pulse current, and 600 W peak pulse power (10/1000 μs). It protects MOSFETs and ICs in industrial sensor signal lines against lightning-induced transients.
For engineers reviewing the 6DFN30A-M3/H datasheet, 6DFN30A-M3/H pinout, 6DFN30A-M3/H application, or 6DFN30A-M3/H equivalent, key selection criteria include unidirectional clamping performance, DFN3820A side-wettable flank compatibility with AOI, 175 °C junction temperature rating, and M3 halogen-free/RoHS-compliant industrial-grade construction.
Technical Context
This device uses passivated anisotropic rectifier technology optimized for low-clamping, high-reliability transient suppression. Its unidirectional configuration provides precise reverse-biased protection with 0.088 %/°C temperature coefficient of VBR, enabling stable operation across -65 °C to +175 °C junction range.
Thermal design is supported by RθJM = 5–6.5 °C/W (junction-to-mount) and RθJA = 140–175 °C/W (junction-to-ambient on FR4), and it meets IEC 61000-4-2 ESD immunity up to ±30 kV (contact/air discharge).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | DO-214AC package; higher RθJA (190 °C/W); 30 V VBR tolerance ±5 % same; 600 W rating | Larger footprint (4.5 × 2.7 mm); no side-wettable flanks; requires X-ray for solder inspection | Choose SMAJ30A only if legacy through-hole or larger SMT footprint is acceptable and AOI is not required. |
| SMCJ30A | DO-214AB package; 600 W rating; VBR 28.5–31.5 V; RθJA ~130 °C/W; no M3 qualification | 5.3 × 4.5 mm body; higher thermal resistance; non-halogen-free option available but M3 not standard | Prefer SMCJ30A when higher surge current margin is needed and board space allows larger package. |

FAQ
What is the exact breakdown voltage range for 6DFN30A-M3/H?
The 6DFN30A-M3/H has a guaranteed breakdown voltage (VBR) range of 28.5 V (min) to 31.5 V (max) at 1.0 mA test current, with 30.0 V nominal. This tight ±5 % tolerance ensures predictable turn-on behavior in precision protection circuits without premature conduction during normal operation.
Does 6DFN30A-M3/H support automatic optical inspection (AOI)?
Yes, the 6DFN30A-M3/H uses a DFN3820A package with side-wettable flanks explicitly designed for AOI. The exposed copper sidewalls allow machine vision systems to verify solder fillet formation and joint integrity without requiring X-ray inspection, reducing final test cost and time.
What is the maximum clamping voltage of 6DFN30A-M3/H under surge conditions?
The 6DFN30A-M3/H exhibits a maximum clamping voltage (VC) of 41.4 V at its rated peak pulse current of 14.5 A (10/1000 μs waveform). This value is measured and guaranteed per Vishay Document Number 98464, ensuring downstream components remain within safe voltage limits during transient events.
Is 6DFN30A-M3/H qualified to AEC-Q101?
No, the 6DFN30A-M3/H carries the /H suffix only in the ordering example table-not in its actual part number. Per Vishay's ordering information, /H denotes AEC-Q101 qualification, but the official part number 6DFN30A-M3/H does not include /H; the "H" in this case is a delivery mode code (7" tape and reel), not a qualification suffix. It is industrial grade.
What is the thermal resistance from junction to mount for 6DFN30A-M3/H?
The 6DFN30A-M3/H has a typical junction-to-mount thermal resistance (RθJM) of 5 °C/W, with a maximum of 6.5 °C/W, measured using JEDEC® 51-14 Transient Dual Interface Method. This low value reflects efficient heat transfer from die to PCB copper via the anode thermal pad.
