Product details
Overview
6DFN82CA-M3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DFN3820A package, designed for clamping voltage transients on signal and power lines. It features 82 V nominal breakdown voltage (VBR), 70.1 V stand-off voltage (VWM), 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current, and 600 W peak pulse power (10/1000 μs). It is used to protect MOSFETs and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the 6DFN82CA-M3/I datasheet, 6DFN82CA-M3/I pinout, 6DFN82CA-M3/I application, or 6DFN82CA-M3/I equivalent, key selection criteria include clamping performance under 10/1000 μs surge, thermal resistance (RθJA = 175 °C/W), bidirectional polarity, MSL Level 1 moisture sensitivity, and compatibility with AOI inspection due to side-wettable flanks.
Technical Context
This TVS device employs anisotropic rectifier technology with junction passivation optimized for high-reliability transient suppression. Its bidirectional configuration enables symmetrical clamping on AC-coupled or differential signal paths without polarity constraints.
It delivers 600 W peak pulse power per 10/1000 μs waveform and sustains operation up to +175 °C junction temperature. Thermal design must account for RθJM = 6.5 °C/W and RθJA = 175 °C/W on standard FR4 PCB, with derating applied above TA = 25 °C per published curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 77.9 / 82.0 / 86.1 V - Ensures reliable turn-on before system overvoltage damage occurs |
| VWM | 70.1 V - Maximum continuous working voltage without leakage degradation |
| VC @ IPPM | 113 V at 5.3 A - Clamping voltage defines worst-case stress on protected IC during surge |
| PPPM | 600 W (10/1000 μs) - Surge energy handling capacity for lightning and inductive switching events |
| TJ max | +175 °C - Enables use in high-ambient industrial environments without thermal shutdown |
| ESD immunity | ±30 kV (IEC 61000-4-2 contact/air) - Robust protection against human-body-model ESD events |
| Package | DFN3820A (3.95 × 2.18 × 0.88 mm) - Low-profile, leadless, AOI-compatible footprint |
Pinout & Package
DFN3820A is a 2-terminal, bidirectional surface-mount package with no cathode marking. Terminals are located on opposite long edges of the rectangular body, enabling symmetric PCB layout and automated optical inspection via side-wettable flanks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal serves as anode or cathode depending on transient polarity; no polarity marking required |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; forms single-channel clamping path across both terminals |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled, differential, or floating signal lines without orientation constraints |
| Side-wettable flanks | Supports automated optical inspection (AOI) for solder joint quality verification in high-volume SMT lines |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 260 °C peak without baking preconditioning |
| Halogen-free, RoHS-compliant (M3) | Meets industrial environmental compliance requirements and JESD201 Class 2 whisker resistance |
| Low profile (0.88 mm height) | Reduces board stack height in space-constrained modules such as sensor nodes and telecom line cards |
Applications
| Industrial Motor Drives | Automotive Sensor Interfaces |
|---|---|
Use Scenario: Protection of gate drivers and feedback signal lines against inductive kickback from relay and solenoid switching. IC Role / Device Role: Transient voltage suppressor placed across MOSFET gate-source or op-amp input pins. Use Value: Limits clamping voltage to 113 V, preventing gate oxide rupture and ensuring >100k surge cycles per IEC 61000-4-5. | Use Scenario: Shielding LIN bus and analog sensor outputs (e.g., pressure, temperature) from load-dump and jump-start transients. IC Role / Device Role: Bidirectional TVS shunting surge energy away from automotive-grade microcontrollers and ADC front-ends. Use Value: Withstands ±30 kV ESD and meets ISO 16750-2 pulse 5a requirements when combined with appropriate series impedance. |
| Telecom Line Cards | Medical Imaging Signal Chains |
Use Scenario: Safeguarding Ethernet PHY interfaces and low-voltage DC power rails from lightning-induced surges on outdoor-facing ports. IC Role / Device Role: Primary-level TVS on RJ45 magnetics secondary side and 3.3 V/5 V supply inputs. Use Value: 600 W peak power rating handles 10/1000 μs surges while maintaining <1 nA leakage at 70.1 V, preserving signal integrity. | Use Scenario: Protecting high-precision analog front-ends (e.g., CT/MRI detector bias lines) from ESD and electrostatic discharge during handling. IC Role / Device Role: Low-capacitance (<50 pF at 0 V) bidirectional clamp on sensitive analog signal paths. Use Value: Junction capacitance remains below 45 pF at VWM, avoiding signal distortion in multi-MHz imaging data acquisition. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ85A-E3/5A (Vishay) | DO-214AC package, unidirectional, 85 V VBR, 135 V VC @ 4.7 A, RθJA ≈ 50 °C/W | Requires polarity-aware layout; higher clamping voltage; better thermal dissipation on large copper pours | Select when board space allows larger package and unidirectional protection suffices with lower thermal resistance needs |
| SMCJ85CA (Littelfuse) | DO-214AB package, bidirectional, 85 V VBR, 137 V VC @ 4.4 A, 1500 W PPPM, RθJA ≈ 20 °C/W | Higher power rating but 3× larger footprint; not AOI-compatible; requires manual visual inspection | Choose for higher-energy surge environments where DFN3820A's 600 W is insufficient and layout area permits larger case |
Compared with SMAJ85A-E3/5A and SMCJ85CA, the 6DFN82CA-M3/I offers superior board-area efficiency, AOI support, and low-profile integration-critical for compact industrial and telecom modules-while trading off absolute power handling and thermal resistance for miniaturization.

FAQ
What is the breakdown voltage tolerance of the 6DFN82CA-M3/I?
The 6DFN82CA-M3/I has a breakdown voltage tolerance of ±5 %, specified as 77.9 V (min), 82.0 V (nominal), and 86.1 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in protected circuits.
Does the 6DFN82CA-M3/I require a specific PCB pad layout?
Yes, the 6DFN82CA-M3/I requires adherence to the DFN3820A mounting pad layout specified in Vishay document 98490, including 0.86 mm wide thermal pads and 0.70 mm solder mask openings. Deviations risk solder bridging, insufficient thermal transfer, or AOI misreads due to non-wettable flank geometry.
Is the 6DFN82CA-M3/I suitable for automotive applications?
The 6DFN82CA-M3/I is rated for industrial grade (M3 suffix, no AEC-Q101 qualification). While it operates from –65 °C to +175 °C and withstands ±30 kV ESD, it lacks formal automotive qualification. For AEC-Q101-compliant designs, consider Vishay's 6DFN82CA-H variants or alternate qualified TVS families.
What is the maximum reverse leakage current of the 6DFN82CA-M3/I at 70.1 V and 150 °C?
At VWM = 70.1 V and TJ = 150 °C, the 6DFN82CA-M3/I exhibits a maximum reverse leakage current of 1.0 μA. This low leakage preserves signal integrity in high-impedance sensor interfaces and avoids unintended bias shifts in precision analog circuits.
How does the 6DFN82CA-M3/I compare to traditional SMA or SMC TVS diodes in surge handling?
The 6DFN82CA-M3/I delivers 600 W peak pulse power (10/1000 μs), matching mid-tier SMA packages but less than SMC-rated devices (e.g., 1500 W). Its advantage lies in footprint reduction (DFN3820A vs. DO-214AC/AB) and AOI compatibility-not raw power. Surge duty cycle and thermal mass of the PCB determine real-world performance equivalence.
