Product details
Overview
6DFN100CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 100 V nominal breakdown voltage (VBR), 85.5 V stand-off voltage (VWM), 137 V maximum clamping voltage at 4.4 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 and telecom signal lines.
For engineers reviewing the 6DFN100CA-M3/H datasheet, 6DFN100CA-M3/H pinout, 6DFN100CA-M3/H application, or 6DFN100CA-M3/H equivalent, key selection criteria include clamping performance at rated IPPM, thermal resistance (RθJA = 140–175 °C/W), MSL Level 1 moisture sensitivity, side-wettable flanks for AOI, and AEC-Q101 qualification indicated by the "H" suffix.
Technical Context
This device employs passivated anisotropic rectifier technology to achieve bidirectional clamping without polarity marking. Its junction passivation and low-profile DFN3820A construction enable high-reliability surge suppression in space-constrained PCB layouts while supporting automated optical inspection via side-wettable flanks.
The 6DFN100CA-M3/H operates across -65 °C to +175 °C junction temperature range and delivers stable clamping under repetitive surge conditions when derated per Fig. 2 of the datasheet. Its 30 kV IEC 61000-4-2 ESD immunity (contact and air discharge) confirms suitability for harsh electromagnetic environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 95.0 / 100 / 105 V - ensures reliable conduction onset above normal operating voltage of 85.5 V systems |
| VWM | 85.5 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA at 25 °C |
| VC @ IPPM | 137 V - clamping voltage at 4.4 A peak pulse current, limiting downstream voltage stress |
| PPPM | 600 W (10/1000 μs) - surge energy handling capacity for standard lightning and switching transient waveforms |
| TJ max | +175 °C - enables operation in high-temperature industrial and automotive under-hood environments |
| RθJA | 140–175 °C/W - defines thermal derating slope on standard FR4 PCB; critical for sustained surge duty cycles |
| ESD immunity | 30 kV contact/air (IEC 61000-4-2) - eliminates need for additional ESD protection stages in front-end interfaces |
Pinout & Package

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-E3/5AT | DO-214AC (SMA) package; higher RθJA (~150 °C/W); unidirectional; no AEC-Q101 rating | Requires polarity-aware layout; less suitable for AC signal lines or automotive use | Select when cost-sensitive, through-hole or legacy SMA footprint required, and AEC-Q101 not mandated |
| SMCJ100A | DO-214AB (SMC) package; 1500 W PPPM; larger footprint (7.11 × 6.22 mm); unidirectional | Better energy handling but incompatible with space-constrained DFN layouts | Select when higher surge margin is needed and board area permits larger SMC package |
Compared with SMAJ100A-E3/5AT and SMCJ100A, the 6DFN100CA-M3/H offers superior board-area efficiency, bidirectional symmetry, AEC-Q101 compliance, and AOI-compatible side-wettable flanks-making it optimal for next-generation automotive, industrial, and telecom modules where miniaturization and process automation are critical.

FAQ
What is the clamping voltage of the 6DFN100CA-M3/H at its rated peak pulse current?
The 6DFN100CA-M3/H has a maximum clamping voltage (VC) of 137 V at its rated peak pulse current (IPPM) of 4.4 A under a 10/1000 μs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Document Number: 98490) and defines the upper voltage limit imposed on protected circuitry during a standardized surge event. The 6DFN100CA-M3/H maintains this clamping performance across its full operating temperature range.
Does the 6DFN100CA-M3/H require a cathode marking for orientation during placement?
No, the 6DFN100CA-M3/H does not have a cathode band or polarity marking because it is a bidirectional transient voltage suppressor. Both terminals are functionally identical, allowing placement in either orientation on the PCB. This simplifies automated pick-and-place programming and eliminates orientation-related assembly errors. The 6DFN100CA-M3/H achieves symmetrical clamping behavior due to its internal passivated anisotropic rectifier structure.
Is the 6DFN100CA-M3/H qualified to AEC-Q101, and how is this reflected in the part number?
Yes, the 6DFN100CA-M3/H is AEC-Q101 qualified. This is explicitly indicated by the "H" suffix in the ordering code, as defined in the Vishay ordering information table (page 3 of Document Number: 98490). The "H" denotes AEC-Q101 qualification, while "M3" specifies halogen-free, RoHS-compliant, and industrial-grade termination. The 6DFN100CA-M3/H has undergone stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 requirements.
What is the moisture sensitivity level (MSL) rating for the 6DFN100CA-M3/H, and what does it mean for assembly?
The 6DFN100CA-M3/H is rated MSL Level 1 per J-STD-020, with a maximum lead-free reflow peak temperature of 260 °C. This means the device has unlimited floor life and can be mounted directly after removal from packaging without baking or dry-pack requirements. The MSL Level 1 rating reflects robust moisture resistance enabled by the DFN3820A molding compound meeting UL 94 V-0 flammability standards. For production using the 6DFN100CA-M3/H, no special handling or preconditioning is needed prior to reflow.
How does the thermal resistance of the 6DFN100CA-M3/H compare between junction-to-ambient and junction-to-mount?
The 6DFN100CA-M3/H has a typical junction-to-ambient thermal resistance (RθJA) of 140 °C/W and a maximum of 175 °C/W on standard FR4 PCB per JEDEC 51-2A. Its junction-to-mount resistance (RθJM) is 5–6.5 °C/W per JEDEC 51-14 TDIM method. This indicates that heat transfer to the PCB copper pad is highly efficient, while ambient convection is the dominant thermal bottleneck. Designers should maximize thermal pad area and use multiple vias to ground planes when using the 6DFN100CA-M3/H in high-duty-cycle surge environments.
