Product details
Overview
6DFN68CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 68 V nominal breakdown voltage (VBR), 58.1 V stand-off voltage (VWM), 92.0 V maximum clamping voltage at 6.5 A peak pulse current, and 600 W peak pulse power rating (10/1000 μs). It protects sensitive ICs and MOSFETs against lightning-induced surges and inductive switching transients in industrial sensor interfaces.
For engineers reviewing the 6DFN68CA-M3/H datasheet, 6DFN68CA-M3/H pinout, 6DFN68CA-M3/H application, or 6DFN68CA-M3/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, bidirectional ESD immunity up to 30 kV (IEC 61000-4-2), thermal resistance (RθJA = 175 °C/W), MSL Level 1 reflow compatibility, and halogen-free RoHS-compliant M3 termination.
Technical Context
This device uses anisotropic rectifier technology with junction passivation for stable bidirectional clamping across -65 °C to +175 °C operating range. Its DFN3820A package features side-wettable flanks enabling automated optical inspection and high-reliability solder joint formation.
The 6DFN68CA-M3/H delivers 92.0 V clamping voltage at 6.5 A IPPM under 10/1000 μs waveform, with <1.0 μA reverse leakage at VWM and 6.0 μA at 150 °C - optimized for low-power signal-line protection where leakage and thermal derating are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 64.6 / 68.0 / 71.4 V - defines minimum voltage at which device enters avalanche conduction during surge events |
| VWM | 58.1 V - maximum continuous working voltage before leakage exceeds 1.0 μA; sets upper limit for normal circuit operation |
| VC @ IPPM | 92.0 V at 6.5 A - clamping voltage during 10/1000 μs surge; determines protected circuit's maximum transient exposure |
| PPPM | 600 W - peak pulse power handling capability; defines energy absorption capacity per transient event |
| TJ max. | +175 °C - maximum junction temperature; enables use in high-ambient industrial environments without derating |
| RθJA | 175 °C/W - thermal resistance junction-to-ambient on standard FR4; informs PCB copper area requirements for thermal management |
| ESD Rating | ±30 kV contact discharge (IEC 61000-4-2) - ensures robustness against human-body-model electrostatic events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/57T | DO-214AC (SMA) package; higher RθJA (150 °C/W); 64 V VWM; 101 V VC @ 6.2 A | Larger footprint (4.5 × 2.7 mm); unsuitable for ultra-thin designs; requires manual AOI adaptation | Select when legacy SMA layout exists and board height >1.1 mm is acceptable |
| SMCJ64A | DO-214AB (SMC) package; 64 V VWM; 103 V VC @ 12.3 A; 1500 W PPPM | Higher power rating but 7.1 × 6.2 mm footprint; incompatible with fine-pitch DFN routing | Choose only for systems requiring >1000 W surge handling and where PCB real estate permits larger case |
Compared with SMAJ64A-E3/57T and SMCJ64A, the 6DFN68CA-M3/H offers superior board-space efficiency (3.95 × 2.18 mm), lower profile (0.88 mm), and native AOI support - making it optimal for next-generation compact, high-density electronics where thermal and spatial constraints dominate.

FAQ
What is the clamping voltage of the 6DFN68CA-M3/H under standard 10/1000 μs surge conditions?
The 6DFN68CA-M3/H exhibits a maximum clamping voltage (VC) of 92.0 V at 6.5 A peak pulse current (IPPM) under the standardized 10/1000 μs double-exponential surge waveform. This value is measured per Figure 3 in Vishay document 98490 and defines the upper voltage limit imposed on protected circuitry during transient events.
Does the 6DFN68CA-M3/H require a cathode marking for orientation during placement?
No, the 6DFN68CA-M3/H is a bidirectional TVS and has no cathode band or polarity marking. Its DFN3820A package contains two identical terminals that function symmetrically - either terminal may connect to line or return, simplifying PCB layout and eliminating orientation errors during automated placement.
Is the 6DFN68CA-M3/H qualified to AEC-Q101 for automotive use?
No, the 6DFN68CA-M3/H carries the "H" suffix in its ordering code but does not indicate AEC-Q101 qualification. Per Vishay's ordering information table (page 3), "H" denotes tape-and-reel packaging (7-inch diameter), not automotive qualification. For AEC-Q101-compliant variants, consult Vishay's 6DFNxxCA-H series with explicit qualification documentation.
What is the maximum junction temperature rating for the 6DFN68CA-M3/H?
The 6DFN68CA-M3/H has a maximum junction temperature (TJ) rating of +175 °C, as specified in the "Maximum Ratings" table of Vishay document 98490. This enables reliable operation in high-ambient environments such as engine compartments, industrial motor drives, and enclosed medical enclosures without thermal shutdown.
How does the 6DFN68CA-M3/H perform under elevated temperature conditions?
At TJ = 150 °C, the 6DFN68CA-M3/H maintains ≤6.0 μA maximum reverse leakage current at VWM, per the "Electrical Characteristics" table. Its pulse power and current ratings are derated above 25 °C per Figure 2, with ~50% PPPM retention at 125 °C ambient - critical for thermal design validation in sealed enclosures.
