Product details
Overview
6DFN30A-M3/I from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, rated for 30 V nominal breakdown voltage (VBR = 28.5–31.5 V), 25.6 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 14.5 A peak pulse current (IPPM) with 41.4 V clamping voltage (VC) and operates from −65 °C to +175 °C - deployed for ESD and surge protection on power rails and signal lines of industrial sensor interfaces.
For engineers reviewing the 6DFN30A-M3/I datasheet, 6DFN30A-M3/I pinout, 6DFN30A-M3/I application, or 6DFN30A-M3/I equivalent, key selection factors include its M3 halogen-free/RoHS-compliant construction, side-wettable flanks for AOI compatibility, unidirectional polarity with cathode band marking, and 600 W transient handling capability in a low-profile 0.88 mm height package.
Technical Context
This device implements an anisotropic rectifier structure with junction passivation optimized for fast response to transients up to 30 kV per IEC 61000-4-2 (contact/air discharge). Its thermal resistance junction-to-mount is 5–6.5 °C/W, enabling effective heat transfer to PCB copper when used with recommended mounting pad layout.
The 6DFN30A-M3/I exhibits a typical VBR temperature coefficient of +0.088 %/°C and maintains stable clamping performance across −65 °C to +175 °C operating range. Its 1.0 mA test current (IT) and ≤1.0 μA reverse leakage at VWM support low-power system-level protection without compromising standby current budgets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V - defines precise voltage threshold at which clamping initiates under 1.0 mA test current |
| VWM | 25.6 V - maximum continuous working voltage before leakage exceeds 1.0 μA, ensuring no false triggering |
| IPPM (10/1000 μs) | 14.5 A - peak surge current it safely shunts without failure, directly determining protected line robustness |
| VC @ IPPM | 41.4 V - clamped voltage during full-rated surge, limiting stress on downstream ICs like microcontrollers or ADCs |
| PPPM (10/1000 μs) | 600 W - total transient energy absorption capacity, defining immunity level against lightning-induced surges |
| TJ max | +175 °C - enables operation in high-temperature environments such as automotive engine bays or industrial motor drives |
| Package | DFN3820A - 2.18 × 3.95 mm outline with side-wettable flanks, compatible with SMP (DO-220AA) footprint and AOI inspection |
Pinout & Package
DFN3820A package: 2-terminal surface-mount device with anode (heatsink) and cathode (marked by color band) terminals; overall dimensions 2.18 mm × 3.95 mm × 0.88 mm; matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |

| Anode | Heatsink / common reference terminal | Connected to PCB ground plane or chassis for thermal dissipation and low-impedance return path during clamping |
| Cathode | Transient-sensing input terminal | Connected to protected line (e.g., 24 V supply rail); color band identifies polarity for correct orientation during placement |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joint quality without X-ray, reducing post-SMT defect escapes |
| Low profile (0.88 mm height) | Supports ultra-thin end equipment designs and avoids mechanical interference with adjacent tall components |
| MSL Level 1 (260 °C peak) | Allows single-reflow assembly without moisture sensitivity concerns, eliminating bake requirements and process delays |
| 30 kV ESD immunity (IEC 61000-4-2) | Provides system-level robustness against human-body-model discharges in handheld or exposed industrial interfaces |
| M3 material grade | Halogen-free, RoHS-compliant, and whisker-resistant (JESD 201 Class 2), meeting industrial and green manufacturing standards |
Applications
| Industrial Sensor Interface Protection | Automotive Body Control Module (BCM) Power Rail |

Use Scenario: Protecting 24 V analog sensor signal lines (e.g., pressure, temperature) from inductive switching spikes in factory automation PLCs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and microcontroller ADC input to clamp transients below 41.4 V. Use Value: Prevents ADC saturation or latch-up while maintaining <1.0 μA leakage at 25.6 V, preserving signal integrity in low-current sensor circuits. |

| Medical Patient Monitor Signal Lines | Telecom Base Station DC Feeds |
|
Use Scenario: Shielding isolated biopotential amplifier inputs (ECG, EEG) from ESD events during clinical handling or cable coupling. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on front-end analog paths to avoid signal distortion while passing IEC 61000-4-2 ±30 kV contact discharge. Use Value: Delivers 30 kV ESD protection without adding measurable capacitance that would degrade high-impedance, low-noise amplifier bandwidth. |
Use Scenario: Hardening −48 V DC power feeds in outdoor telecom cabinets against lightning-induced surges entering via long feeder cables. IC Role / Device Role / Timing Role: Secondary surge suppression stage after gas discharge tube (GDT), clamping residual transients before PoE or RF subsystems. Use Value: Withstands repeated 600 W pulses and operates reliably up to +175 °C ambient, supporting extended field life in uncooled enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | DO-214AC (SMA) package; 30 V VBR, 48.4 V VC @ 12.3 A; higher clamping voltage and larger footprint | Less suitable for space-constrained PCBs; requires manual or wave-solder rework due to non-AOI-friendly leads | Choose SMAJ30A only if legacy board design mandates SMA footprint or higher surge margin beyond 600 W is required. |
| SMCJ30A | DO-214AB (SMC) package; same VBR, but 49.9 V VC @ 12.0 A; 1500 W rating, larger thermal mass | Better for high-energy surges but incompatible with fine-pitch DFN layouts; not AOI-compatible | Select SMCJ30A when protecting high-power subsystems where 1500 W pulse handling outweighs size and inspection constraints. |
Compared with SMAJ30A and SMCJ30A, the 6DFN30A-M3/I offers superior board-area efficiency, AOI-ready side-wettable flanks, and lower clamping voltage (41.4 V vs. ≥48.4 V), making it optimal for modern high-density industrial and automotive electronics where layout space and automated assembly yield are critical.

FAQ
What is the exact breakdown voltage tolerance for 6DFN30A-M3/I?
The 6DFN30A-M3/I has a breakdown voltage (VBR) specified at 28.5 V (min), 30.0 V (nom), and 31.5 V (max) measured at 1.0 mA test current (IT). This ±5 % tolerance is confirmed in the Electrical Characteristics table of Vishay document 98464 and applies strictly to the 6DFN30A variant within the 6DFN12A–6DFN51A family.
Does 6DFN30A-M3/I support automatic optical inspection (AOI)?
Yes, the 6DFN30A-M3/I uses a DFN3820A package with side-wettable flanks specifically designed for AOI compatibility. Vishay explicitly states this feature in the "Features" section of document 98464, enabling reliable solder-joint verification without X-ray inspection during high-volume SMT assembly.
What is the maximum clamping voltage of 6DFN30A-M3/I under full-rated surge?
The 6DFN30A-M3/I clamps to 41.4 V when subjected to its rated 14.5 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is listed in the Electrical Characteristics table of Vishay's 98464 datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is 6DFN30A-M3/I qualified to AEC-Q101 for automotive use?
No, the 6DFN30A-M3/I carries the "I" package code indicating 13" tape-and-reel delivery, not AEC-Q101 qualification. Only variants with "H" suffix (e.g., 6DFN30A-M3/H) are AEC-Q101 qualified per the Ordering Information Table in document 98464. The 6DFN30A-M3/I is industrial-grade.
What does the "M3" suffix mean in 6DFN30A-M3/I?
The "M3" suffix in 6DFN30A-M3/I denotes halogen-free, RoHS-compliant construction with matte tin-plated terminations and JESD 201 Class 2 whisker resistance. This material specification is defined in the Mechanical Data section of Vishay document 98464 and ensures environmental compliance and long-term solder joint reliability.
