Product details
Overview
6DFN82CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 82 V nominal breakdown voltage (VBR = 77.9–86.1 V), 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 protects signal lines in sensor units and MOSFET gates against lightning-induced transients and inductive switching surges.
For engineers reviewing the 6DFN82CA-M3/H datasheet, 6DFN82CA-M3/H pinout, 6DFN82CA-M3/H application, or 6DFN82CA-M3/H equivalent, this page delivers verified electrical parameters, thermal derating behavior, ESD immunity (30 kV contact/air), MSL Level 1 reflow compatibility, and precise DFN3820A mechanical dimensions for AOI-ready placement and layout validation.
Technical Context
This device uses anisotropic rectifier technology with junction passivation to achieve stable bidirectional clamping without polarity marking. Its low-profile DFN3820A package features side-wettable flanks for automated optical inspection and supports high-density PCB layouts where height is constrained to ≤0.88 mm.
The 6DFN82CA-M3/H operates across -65 °C to +175 °C junction temperature range, with thermal resistance RθJA up to 175 °C/W (JEDEC 51-2A) and RθJM as low as 5 °C/W (JEDEC 51-14 TDIM), enabling reliable surge handling in thermally demanding industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 77.9 / 82.0 / 86.1 V - ensures consistent breakdown initiation above system operating voltage while accommodating process variation |
| VWM | 70.1 V - defines maximum continuous reverse voltage before leakage exceeds 1.0 μA, preserving signal integrity during normal operation |
| VC @ IPPM | 113 V at 5.3 A - limits protected circuit voltage during 10/1000 μs surge, directly bounding stress on downstream ICs |
| PPPM | 600 W - sustains standardized lightning/surge energy per IEC 61000-4-5 without degradation |
| TJ max | +175 °C - enables use in under-hood automotive or high-temperature industrial enclosures without thermal shutdown |
| ESD immunity | 30 kV contact & air discharge (IEC 61000-4-2) - provides robust handling protection during assembly and field service |
| MSL level | Level 1 (J-STD-020) - allows unlimited floor life and single-reflow at 260 °C peak, simplifying SMT manufacturing |
Pinout & Package
Package: DFN3820A - leadless, 2-terminal surface-mount package measuring 3.95 mm × 2.18 mm × 0.88 mm (L × W × H), with side-wettable flanks for AOI and compatible footprint with SMP (DO-220AA).

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, 85 V VBR, 600 W, but 2.79 mm height and no side-wettable flanks | Less suitable for AOI and ultra-low-profile designs; requires larger PCB footprint | Select when legacy through-hole or higher-profile SMT is acceptable and AOI capability is not required |
| SMCJ85CA (Littelfuse) | DO-214AB package, 85 V VBR, 1500 W rating, but 4.45 mm height and no MSL Level 1 qualification | Better for high-energy surges but incompatible with fine-pitch automated assembly and reflow profiles >230 °C | Choose only when peak power demand exceeds 600 W and board height allowance permits larger package |
Compared with SMAJ85A-E3/5A and SMCJ85CA, the 6DFN82CA-M3/H offers superior manufacturability in high-density layouts due to its 0.88 mm height and AOI-compatible DFN3820A package, while delivering matched clamping performance and automotive-grade reliability without sacrificing surge margin.

FAQ
What is the breakdown voltage tolerance of the 6DFN82CA-M3/H?
The 6DFN82CA-M3/H has a ±5 % breakdown voltage tolerance, specified as 77.9 V (min) to 86.1 V (max) at 1.0 mA test current. This tight tolerance ensures predictable clamping onset across production lots and supports precise system-level overvoltage margining in safety-critical designs.
Does the 6DFN82CA-M3/H require a heatsink for 600 W surge handling?
No, the 6DFN82CA-M3/H does not require an external heatsink. Its DFN3820A package achieves RθJM as low as 5 °C/W when mounted to a 1-in² 2 oz. copper pad, enabling full 600 W (10/1000 μs) surge dissipation within its +175 °C TJ limit without auxiliary cooling.
Is the 6DFN82CA-M3/H compatible with lead-free reflow profiles?
Yes, the 6DFN82CA-M3/H is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102, ensuring reliable solder joint formation in standard lead-free SMT processes.
How does the 6DFN82CA-M3/H perform at elevated ambient temperatures?
The 6DFN82CA-M3/H derates linearly above 25 °C ambient: at 100 °C, its peak pulse power drops to ~420 W (70 % of rated 600 W), per Figure 2 in the datasheet. This behavior is fully characterized and enables accurate thermal design for under-hood or enclosed industrial deployments.
Can the 6DFN82CA-M3/H be used in unidirectional configurations?
No - the 6DFN82CA-M3/H is inherently bidirectional and lacks cathode marking. For unidirectional protection, Vishay offers the 6DFN82A-M3/H variant (anode-cathode marked); using the CA version in unidirectional circuits may result in unintended conduction during negative transients.
