Product details
Overview
6DFN12CA-M3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in DFN3820A package, featuring 12 V nominal breakdown voltage (VBR = 11.4–12.6 V), 10.2 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 35.9 A peak pulse current and clamps to 16.7 V at rated surge, protecting sensitive ICs and MOSFETs in compact consumer and industrial electronics.
For engineers reviewing the 6DFN12CA-M3/I datasheet, 6DFN12CA-M3/I pinout, 6DFN12CA-M3/I application, or 6DFN12CA-M3/I equivalent, key selection criteria include bidirectional clamping capability, low-profile DFN3820A footprint with side-wettable flanks for AOI, MSL Level 1 rating, and 30 kV ESD immunity per IEC 61000-4-2 - all critical for high-reliability signal-line protection in space-constrained designs.
Technical Context
This TVS uses anisotropic rectifier technology with junction passivation optimized for fast response to transients induced by inductive switching or lightning surges. Its bidirectional configuration enables symmetric clamping across both polarities without polarity marking, supporting unidirectional or differential signal line protection.
The device operates over -65 °C to +175 °C junction temperature range and features thermal resistance RθJA of 140–175 °C/W on FR4 PCB. Its 0.88 mm typical height and DFN3820A mechanical outline (3.95 mm × 2.18 mm) ensure compatibility with SMP (DO-220AA) layout footprints while enabling automated placement and AOI inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 11.4 / 12.0 / 12.6 V - defines minimum voltage at which device enters avalanche conduction under 1 mA test current |
| VWM | 10.2 V - maximum continuous reverse working voltage before leakage exceeds 2 μA |
| IPPM (10/1000 μs) | 35.9 A - peak surge current it safely clamps without failure, directly determining protected circuit's surge withstand margin |
| VC @ IPPM | 16.7 V - maximum clamped voltage during rated surge, defining worst-case overvoltage seen by downstream IC |
| PPPM | 600 W - peak pulse power handling capacity, enabling robust protection against IEC 61000-4-5 level 3/4 surges |
| Junction temp. range | -65 °C to +175 °C - supports operation in automotive under-hood, industrial motor control, and medical equipment environments |
| ESD immunity | ±30 kV contact/air (IEC 61000-4-2) - eliminates need for additional ESD stages on exposed ports |
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 automated optical inspection and compatible with DO-220AA (SMP) board layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | No polarity marking; either terminal serves as anode or cathode depending on transient polarity - simplifies PCB routing and eliminates orientation errors |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; forms symmetrical clamping path across protected line - required for differential or AC-coupled signal protection |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or ungrounded sensor lines without polarity constraints |
| Side-wettable flanks | Supports automated optical inspection (AOI) of solder joints - critical for zero-defect manufacturing in automotive and medical assembly lines |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 260 °C peak - eliminates baking requirements and streamlines SMT production |
| Halogen-free & RoHS-compliant (M3) | Fulfills environmental compliance for global markets including EU, China, and Japan without sacrificing thermal or electrical performance |
| Low profile (0.88 mm) | Reduces board stack height in ultra-thin consumer devices (e.g., wearables, IoT sensors) where vertical clearance is constrained |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A-E3/57T | DO-214AC (SMA) package; higher RθJA (150 °C/W); 12 V unidirectional; VC = 19.9 V @ 30.1 A | Requires polarity-aware layout; larger footprint (4.5 × 2.7 mm); less suitable for ultra-thin or high-density boards | Select when legacy SMA footprint exists or when unidirectional clamping suffices and AOI is not required |
| SMCJ12CA | DO-214AB (SMC) package; 1500 W rating; VC = 19.9 V @ 75.4 A; 2.4 mm height | Higher power but 2.7× taller; used in industrial power supply inputs rather than signal lines | Select only for higher-energy surge categories (e.g., IEC 61000-4-5 level 4) where 600 W is insufficient |
Compared with SMAJ12A-E3/57T and SMCJ12CA, the 6DFN12CA-M3/I provides superior board-area efficiency, AOI-compatible side-wettable flanks, and lower clamping voltage (16.7 V vs. 19.9 V), making it optimal for high-density signal-line protection where space, manufacturability, and low clamping overhead are prioritized.

FAQ
What is the breakdown voltage tolerance of the 6DFN12CA-M3/I?
The 6DFN12CA-M3/I has a breakdown voltage tolerance of ±5 %, specified as 11.4 V (min) to 12.6 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in protected circuits.
Does the 6DFN12CA-M3/I require a heatsink for 600 W surge handling?
No, the 6DFN12CA-M3/I does not require an external heatsink for single-event 600 W (10/1000 μs) surge handling. Its thermal design relies on transient junction-to-mount thermal resistance (RθJM = 5–6.5 °C/W) and PCB copper area; standard 2 oz. FR4 land pattern suffices for typical surge duty cycles.
Is the 6DFN12CA-M3/I suitable for automotive applications?
Yes, the 6DFN12CA-M3/I is suitable for automotive applications due to its -65 °C to +175 °C operating junction temperature range, MSL Level 1 reflow compatibility, and robust 30 kV ESD immunity. While not AEC-Q101 qualified (denoted by 'H' suffix), its industrial-grade M3 construction meets many non-safety-critical automotive subsystem requirements.
How does the side-wettable flank feature benefit manufacturing of the 6DFN12CA-M3/I?
The side-wettable flanks on the 6DFN12CA-M3/I enable automated optical inspection (AOI) of solder joint quality on the DFN3820A package - a capability unavailable with standard DFN variants. This reduces post-reflow defect escapes in high-volume production of consumer and industrial electronics.
What is the maximum clamping voltage of the 6DFN12CA-M3/I at its rated peak pulse current?
The maximum clamping voltage (VC) of the 6DFN12CA-M3/I is 16.7 V at its rated peak pulse current of 35.9 A (10/1000 μs waveform). This value represents the worst-case overvoltage imposed on protected circuitry during a full-rated transient event.
