Product details
Overview
6DFN24CA-M3/I from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, featuring 24 V nominal breakdown voltage (VBR = 22.8–25.2 V), 20.5 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), and 18.1 A peak pulse current (IPPM). It protects signal lines in sensor units and MOSFET gate drivers against lightning-induced transients and inductive switching surges.
For engineers reviewing the 6DFN24CA-M3/I datasheet, 6DFN24CA-M3/I pinout, 6DFN24CA-M3/I application, or 6DFN24CA-M3/I equivalent, key selection criteria include clamping voltage (VC = 33.2 V at IPPM), low-profile 0.88 mm height, side-wettable flanks for AOI, and M3-grade halogen-free RoHS-compliant construction.
Technical Context
This device uses passivated anisotropic rectifier technology to achieve bidirectional clamping with symmetrical breakdown characteristics. Its junction passivation enables stable operation up to TJ = 175 °C and supports MSL Level 1 reflow compatibility (260 °C peak).
The DFN3820A package delivers low thermal resistance (RθJM = 5–6.5 °C/W) and high surge immunity (30 kV ESD per IEC 61000-4-2 contact/air discharge), making it suitable for compact, high-reliability PCB layouts where space and thermal management are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 22.8 / 24.0 / 25.2 V - ensures reliable conduction onset above 20.5 V operating voltage without false triggering |
| VWM | 20.5 V - maximum continuous reverse voltage before leakage exceeds 1 μA at 25 °C |
| VC @ IPPM | 33.2 V - clamped voltage during 18.1 A 10/1000 μs surge, limiting downstream IC stress |
| PPPM | 600 W - peak transient energy absorption capability under standardized surge waveform |
| IPPM | 18.1 A - maximum non-repetitive surge current the device sustains without failure |
| TJ max | +175 °C - extended junction temperature rating enables use in under-hood or industrial enclosures |
| ESD immunity | 30 kV contact/air - meets IEC 61000-4-2 for robust handling and system-level ESD resilience |
Pinout & Package
Package: DFN3820A - leadless, 2-terminal surface-mount package with side-wettable flanks (0.078 × 0.086 in / 1.98 × 2.18 mm footprint, 0.031 in / 0.79 mm height), compatible with SMP (DO-220AA) outline and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Non-polarized terminal - functions identically as either anode or cathode due to symmetric internal structure |
| Terminal 2 | Anode/Cathode (bidirectional) | Paired terminal completing the bidirectional clamping path; no polarity marking required |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines without polarity constraints |
| Side-wettable flanks | Supports automated optical inspection (AOI) of solder joint quality on both lateral edges |
| Low profile (0.88 mm) | Reduces board stack height in space-constrained modules such as wearables and sensor nodes |
| M3 material grade | Halogen-free, RoHS-compliant, Pb-free terminations qualified to JESD 201 Class 2 whisker resistance |
| MSL Level 1 | Allows unlimited floor life and standard reflow without dry-pack or baking requirements |
Applications
| Automotive Sensor Protection | Industrial I/O Interface Protection |

| Medical Patient Monitoring Inputs | Consumer IoT Sensor Nodes |
|
Use Scenario: Shielding ECG/EEG front-end amplifier inputs from electrostatic discharge and defibrillator-induced transients in portable diagnostic devices. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <100 pF at 0 V) placed directly at connector entry point to minimize signal distortion on high-impedance biopotential paths. Use Value: Clamps 10/1000 μs surges to ≤33.2 V while adding negligible loading (<1 μA leakage at 20.5 V), preserving DC accuracy and SNR. |
Use Scenario: Protecting I²C/SPI lines and GPIOs of battery-powered environmental sensors (e.g., humidity, motion) from ESD during handling and deployment. IC Role / Device Role / Timing Role: Single-component bidirectional protection on each signal line, leveraging compact DFN3820A footprint to minimize PCB area in coin-cell-sized modules. Use Value: 0.88 mm height and 1.98 × 2.18 mm footprint enable integration into ultra-thin wearable enclosures without compromising surge margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T | DO-214AC (SMA) package, 24 V unidirectional, 400 W PPPM, higher VC = 38.9 V | Requires external polarity management; larger footprint (4.5 × 2.7 mm) and 2.2 mm height | Choose when legacy SMA layout exists and unidirectional protection suffices with lower cost. |
| SMCJ24CA | DO-214AB (SMC) package, 24 V bidirectional, 1500 W PPPM, VC = 38.9 V, 7.1 × 6.2 mm | Higher power rating but 3× larger footprint and 2.6 mm height - unsuitable for ultra-thin designs | Choose only when >600 W surge margin is mandatory and board space permits SMC package. |
Compared with SMAJ24A-E3/57T and SMCJ24CA, the 6DFN24CA-M3/I offers superior board-area efficiency (1.98 × 2.18 mm vs. ≥4.5 × 2.7 mm), lower clamping voltage (33.2 V vs. 38.9 V), and AOI-compatible side-wettable flanks - critical for high-volume automated assembly of miniaturized electronics.

FAQ
What is the breakdown voltage tolerance of the 6DFN24CA-M3/I?
The 6DFN24CA-M3/I has a ±5 % breakdown voltage tolerance, specified as 22.8 V (min) to 25.2 V (max) at 1.0 mA test current. This tight tolerance ensures predictable clamping onset across production lots and supports precise overvoltage margin design in safety-critical circuits.
Does the 6DFN24CA-M3/I require a heatsink for 600 W surge dissipation?
No, the 6DFN24CA-M3/I does not require an external heatsink for single-event 600 W (10/1000 μs) surges. Its DFN3820A package achieves low junction-to-mount thermal resistance (RθJM = 5–6.5 °C/W), enabling effective transient heat transfer to the PCB copper pour without auxiliary cooling.
Is the 6DFN24CA-M3/I compatible with lead-free reflow profiles?
Yes, the 6DFN24CA-M3/I 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 JESD 22-B102, ensuring reliable solderability in standard lead-free assembly processes.
How does the clamping voltage of 6DFN24CA-M3/I compare to its stand-off voltage?
The 6DFN24CA-M3/I clamps at 33.2 V under 18.1 A surge (10/1000 μs), which is 12.7 V above its 20.5 V stand-off voltage (VWM). This 62 % overvoltage margin provides robust protection headroom while remaining within safe operating limits for 24 V-rated downstream components.
Can the 6DFN24CA-M3/I be used in bidirectional signal lines like USB or RS-485?
Yes, the 6DFN24CA-M3/I is explicitly designed for bidirectional signal protection. Its symmetrical breakdown characteristic and lack of polarity marking allow direct placement across differential pairs (e.g., RS-485 A/B) or AC-coupled lines (e.g., USB D+/D−) without orientation concerns.
