Product details
Overview
6DFN100CA-M3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) in DFN3820A package, designed for clamping 100 V breakdown transients with 600 W peak pulse power (10/1000 μs), 4.4 A peak surge current, and 137 V maximum clamping voltage - deployed on signal lines of industrial sensor units and telecom interfaces.
For engineers reviewing the 6DFN100CA-M3/I datasheet, 6DFN100CA-M3/I pinout, 6DFN100CA-M3/I application, or 6DFN100CA-M3/I equivalent, key selection criteria include standoff voltage (85.5 V), junction temperature range (–65 °C to +175 °C), MSL Level 1 rating, side-wettable flanks for AOI, and halogen-free RoHS-compliant M3 termination.
Technical Context
This TVS diode uses anisotropic rectifier technology with junction passivation for stable bidirectional clamping across –65 °C to +175 °C operating range. It delivers 137 V clamping at 4.4 A IPPM under 10/1000 μs waveform, with thermal resistance RθJA up to 175 °C/W and RθJM as low as 5 °C/W.
The DFN3820A package features side-wettable flanks compatible with automated optical inspection and reflow profiles peaking at 260 °C (MSL Level 1). Its 0.88 mm typical height and SMP (DO-220AA)-compatible outline support high-density PCB layouts in space-constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 95.0 V min / 100 V nom / 105 V max - defines precise clamping onset threshold at 1 mA test current |
| Standoff Voltage VWM | 85.5 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA at 25 °C |
| Peak Pulse Power PPPM | 600 W (10/1000 μs) - sustains transient energy without failure in standard lightning/surge tests |
| Clamping Voltage VC | 137 V at 4.4 A IPPM - limits downstream voltage stress during worst-case surge 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 |
|---|---|---|---|
| SMAJ100A-E3/57T | DO-214AC (SMA) package, 100 V VBR, 400 W PPPM, higher RθJA (~190 °C/W), unidirectional | Requires external polarity management; less suitable for differential or AC-coupled lines | Select when legacy SMA footprint is fixed and bidirectionality is not required |
| SMCJ100A | DO-214AB (SMC) package, 100 V VBR, 1500 W PPPM, 10× larger footprint, unidirectional | Higher power handling but incompatible with space-constrained designs and AOI processes | Choose only when surge energy exceeds 600 W and board area permits larger case |

FAQ
What is the standoff voltage rating of the 6DFN100CA-M3/I?
The 6DFN100CA-M3/I has a maximum standoff voltage (VWM) of 85.5 V at 25 °C, ensuring minimal leakage (<1.0 μA) during normal operation while allowing reliable clamping above this threshold. This value is confirmed in the Electrical Characteristics table of Vishay document 98490 and remains valid up to 150 °C junction temperature.
Does the 6DFN100CA-M3/I require a cathode marking for PCB layout?
No - the 6DFN100CA-M3/I is a bidirectional TVS diode with no cathode band or polarity marking, as explicitly stated in the Mechanical Data section of the datasheet. Both terminals are functionally identical, enabling flexible placement in either orientation on the PCB without affecting clamping performance.
Is the 6DFN100CA-M3/I compatible with standard reflow profiles?
Yes - the 6DFN100CA-M3/I meets MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, eliminating the need for moisture-sensitive device baking prior to assembly. Its DFN3820A package is qualified for standard lead-free reflow processes used in high-volume SMT lines.
What is the maximum clamping voltage of the 6DFN100CA-M3/I under surge conditions?
The 6DFN100CA-M3/I exhibits a maximum clamping voltage (VC) of 137 V at 4.4 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured and guaranteed per the Electrical Characteristics table in Vishay document 98490 and defines the upper voltage limit imposed on protected circuits during surge events.
How does the DFN3820A package of the 6DFN100CA-M3/I support automated optical inspection?
The DFN3820A package of the 6DFN100CA-M3/I features side-wettable flanks - exposed copper terminations along the package edges - which enable reliable solder-joint inspection using automated optical inspection (AOI) systems. This design is explicitly cited in the FEATURES section of the datasheet as a key enabler for high-yield, traceable manufacturing.
