Product details
Overview
6DFN13A-M3/I from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, featuring 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 33.0 A peak pulse current, and clamping voltage of 18.2 V at rated surge. It protects MOSFETs and ICs against inductive switching transients and lightning surges in industrial sensor signal lines.
For engineers reviewing the 6DFN13A-M3/I datasheet, 6DFN13A-M3/I pinout, 6DFN13A-M3/I application, or 6DFN13A-M3/I equivalent, this page delivers verified electrical parameters, thermal resistance values (RθJA = 175 °C/W), ESD immunity (30 kV contact), polarity marking (cathode band), and AOI-compatible side-wettable flanks for automated optical inspection.
Technical Context
This unidirectional TVS diode uses passivated anisotropic rectifier technology to deliver precise clamping with low leakage (<2.0 μA at VWM) and stable temperature coefficient (αT = 0.072 %/°C). Its DFN3820A footprint enables high-density PCB layouts while maintaining robust thermal performance via low RθJM (6.5 °C/W).
The device operates across -65 °C to +175 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its 0.88 mm profile and matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (nom) | 13.0 V - ensures reliable conduction onset above 11.1 V operating voltage without false triggering |
| VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 2.0 μA, compatible with 12 V rail systems |
| PPPM | 600 W (10/1000 μs) - handles high-energy transients common in automotive and industrial load-switching environments |
| IPPM | 33.0 A - peak surge current capability validated per IEC 61000-4-5 waveform compliance |
| VC @ IPPM | 18.2 V - clamping voltage limits downstream component stress during surge events |
| RθJA | 175 °C/W - defines thermal derating limit on standard FR4 PCB; requires heatsinking for sustained >1 W dissipation |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - provides robust protection for exposed I/O pins in consumer and telecom interfaces |
Pinout & Package
Package: DFN3820A - 2-terminal, leadless, side-wettable flanks, 3.95 mm × 2.18 mm × 0.88 mm, cathode marked by color band. Anode connected to exposed thermal pad (heatsink).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (thermal pad) | Current return path & thermal interface | Must be soldered to large copper pour for effective heat dissipation; electrically tied to cathode-side ground in unidirectional configuration |
| Cathode (marked terminal) | Transient current sink | Connected to protected line; conducts surge current to ground when VIN exceeds VBR; polarity band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing post-reflow defect escape |
| Low-profile height (0.88 mm) | Supports ultra-thin end equipment designs including portable medical sensors and space-constrained IoT nodes |
| Halogen-free, RoHS-compliant (M3) | Fulfills IPC-1752A material declaration requirements and supports green manufacturing compliance programs |
| Junction passivation | Prevents moisture-induced degradation and leakage drift over 15+ year field life in humid industrial environments |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing without dry pack or baking, simplifying SMT line logistics |
Applications
| Industrial Sensor Protection | Automotive Body Control Module |
|---|---|
Use Scenario: Protecting 12 V CAN/LIN bus signal lines in factory-floor pressure and temperature sensors exposed to relay coil flyback. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between signal line and chassis ground to shunt transients before reaching transceiver input. Use Value: Limits clamped voltage to 18.2 V, staying below 24 V absolute max rating of typical LIN transceivers and preventing latch-up. |
Use Scenario: Safeguarding microcontroller GPIOs driving solenoid valves in door lock actuators subject to ISO 7637-2 Pulse 1/2a. IC Role / Device Role / Timing Role: Standoff-rated (11.1 V) suppression device mounted at PCB edge near connector to intercept coupled energy before entering MCU domain. Use Value: Withstands 33.0 A surge current and maintains <2.0 μA leakage at 12 V battery rail, ensuring no standby current penalty. |
| Medical Patient Monitor Interface | Telecom Power Supply Input |
Use Scenario: Shielding analog front-end inputs of ECG/SpO₂ modules from ESD events during clinical handling and cable coupling. IC Role / Device Role / Timing Role: Fast-response (sub-nanosecond) transient suppressor placed directly at connector entry point, ahead of instrumentation amplifier. Use Value: 30 kV IEC 61000-4-2 contact discharge rating prevents damage to precision op-amps while adding <1 pF parasitic capacitance. |
Use Scenario: Secondary-side surge protection on 48 V DC-DC converter output feeding Ethernet PHYs in PoE-powered access points. IC Role / Device Role / Timing Role: Low-leakage (2.0 μA) unidirectional clamp installed between VOUT and GND to absorb residual transients escaping primary-side MOVs. Use Value: Clamps to 18.2 V within 1 ns, protecting 3.3 V/5 V logic rails downstream without affecting regulation stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | DO-214AC package (SMA), 13.3 V VBR, 600 W rating, RθJA = 50 °C/W, height 2.3 mm | Higher thermal resistance and larger footprint; suitable where board space is unconstrained but thermal mass is available | Select SMAJ13A only if legacy SMA layout exists and AOI inspection is not required. |
| SMF13A | SOD-123FL package, 13.3 V VBR, 200 W rating, 1.1 mm height, no side-wettable flanks | Lower power handling (200 W vs. 600 W); insufficient for IEC 61000-4-5 level 3/4 surges | Choose SMF13A only for low-energy ESD-only scenarios where cost is critical and surge immunity is secondary. |
Compared with SMAJ13A and SMF13A, the 6DFN13A-M3/I delivers superior power density (600 W in 3.95 mm × 2.18 mm), AOI-ready construction, and lower thermal resistance to mount (RθJM = 6.5 °C/W), making it optimal for next-generation compact, high-reliability industrial and automotive modules.

FAQ
What is the exact breakdown voltage tolerance for 6DFN13A-M3/I?
The 6DFN13A-M3/I has a breakdown voltage (VBR) range of 12.4 V (min) to 13.7 V (max) at 1.0 mA test current, corresponding to ±5 % tolerance around the nominal 13.0 V value as specified in the Vishay datasheet document 98464, revision 10-Nov-2023.
Does 6DFN13A-M3/I support automatic optical inspection (AOI)?
Yes, the 6DFN13A-M3/I features side-wettable flanks in its DFN3820A package, enabling reliable solder joint inspection using standard AOI systems without requiring X-ray verification - a key advantage over non-wettable DFN variants and traditional SMD packages.
What is the maximum operating junction temperature for 6DFN13A-M3/I?
The 6DFN13A-M3/I has a maximum operating junction temperature (TJmax) of +175 °C, allowing operation in under-hood automotive environments and high-temperature industrial enclosures where ambient temperatures exceed 125 °C.
How does the clamping voltage of 6DFN13A-M3/I compare to its stand-off voltage?
The 6DFN13A-M3/I clamps to 18.2 V at its rated 33.0 A peak pulse current, which is 7.1 V above its 11.1 V stand-off voltage (VWM). This 64 % overvoltage margin ensures safe operation for 12 V systems while preserving noise margin for downstream ICs.
Is 6DFN13A-M3/I compliant with AEC-Q101 automotive qualification?
No, the 6DFN13A-M3/I carries the "M3" suffix indicating halogen-free, RoHS-compliant, industrial-grade qualification - not AEC-Q101. For automotive-qualified equivalents, refer to Vishay's "H"-suffixed variants such as 6DFN13A-M3/H, which are explicitly qualified to AEC-Q101.
