Product details
Overview
6DFN15A-M3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DFN3820A package, designed for robust ESD and surge protection of low-voltage signal lines. It features 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 21.2 V maximum clamping voltage (VC) at 5.0 A peak pulse current, 600 W peak pulse power (10/1000 μs), and operates from –65 °C to +175 °C - deployed in sensor interface protection for automotive body control modules.
For engineers reviewing the 6DFN15A-M3/H datasheet, 6DFN15A-M3/H pinout, 6DFN15A-M3/H application, or 6DFN15A-M3/H equivalent, this page delivers verified electrical parameters, thermal resistance values (RθJA = 175 °C/W), JEDEC-compliant MSL level 1 reflow rating, side-wettable flank geometry for AOI, and precise DFN3820A mechanical dimensions - all critical for layout validation and reliability qualification.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for fast response to transients up to 30 kV ESD (IEC 61000-4-2 contact/air discharge). Its unidirectional configuration provides low leakage (<1.0 μA at VWM) and tight VBR tolerance (±5 %), enabling stable clamping on 12 V rail interfaces without false triggering.
The DFN3820A package integrates a thermally efficient junction-to-mount path (RθJM = 6.5 °C/W) and meets UL 94 V-0 flammability. The M3 suffix confirms halogen-free, RoHS-compliant, Pb-free matte tin terminations qualified per JESD 201 Class 2 whisker test - essential for industrial and automotive-grade production.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 14.3 / 15.0 / 15.8 V - ensures reliable turn-on above 12.8 V system stand-off while avoiding nuisance conduction during normal operation |
| VC @ IPPM | 21.2 V at 5.0 A - limits downstream IC voltage stress to safe levels during 600 W transient events |
| IR @ VWM | <1.0 μA at 12.8 V - minimizes standby power loss and prevents signal integrity degradation on high-impedance lines |
| TJ max | +175 °C - supports under-hood automotive placement and long-term reliability in thermally aggressive environments |
| RθJA | 175 °C/W - defines worst-case thermal rise on standard FR4 PCB; requires adequate copper pour for sustained surge duty |
| ESD Rating | ±30 kV (IEC 61000-4-2 contact/air) - exceeds Level 4 immunity requirements for exposed connectors and sensors |
Pinout & Package
Package: DFN3820A - leadless, 2-terminal surface-mount device with side-wettable flanks (0.79 mm × 2.18 mm footprint, 0.88 mm typical height), compatible with SMP (DO-220AA) outline and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal (heatsink side) | Connected to ground or low-impedance return path; serves as thermal interface and current return during clamping |
| Cathode | Negative terminal (marked with color band) | Connected to protected line; conducts surge current toward ground when VBR exceeded |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables 100 % automated optical inspection (AOI) of solder joint quality without X-ray |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 260 °C peak without baking |
| Passivated anisotropic rectifier | Delivers stable VBR over temperature and lifetime with <0.076 %/°C tempco |
| Halogen-free & RoHS | M3 suffix certifies compliance with environmental regulations and JESD 201 Class 2 whisker resistance |
Applications
| Automotive Body Control Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting LIN bus transceivers and door module microcontrollers from load-dump and inductive switching transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between LIN data line and chassis ground to clamp surges before they reach the transceiver input. Use Value: 21.2 V clamping voltage ensures transceiver I/O remains within absolute maximum ratings during ISO 7637-2 Pulse 1/2a events. | Use Scenario: Safeguarding analog output (4–20 mA) and digital I/O lines of pressure/temperature sensors in factory automation PLCs. IC Role / Device Role / Timing Role: Standoff protection element on sensor signal traces, absorbing lightning-induced surges on field wiring. Use Value: 600 W peak pulse power rating handles repetitive 10/1000 μs transients per IEC 61000-4-5 Level 3 without degradation. |
| Medical Patient Monitor Port | Telecom Base Station Front-End |

IC Role / Device Role / Timing Role: Secondary-level transient suppressor downstream of gas discharge tube (GDT) primary protection. Use Value: Low 1.0 μA leakage at 12.8 V prevents bias shift in precision termination networks and maintains signal fidelity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | DO-214AC package; higher RθJA (150 °C/W); 24.4 V VC @ 5.0 A; same VBR range | Larger footprint (4.5 × 2.7 mm vs. 2.18 × 0.79 mm); less suitable for ultra-dense layouts | Select SMAJ15A only if board space allows larger SMC footprint and higher clamping voltage is acceptable |
| SMF15A | SOD-123FL package; 23.2 V VC @ 5.0 A; 175 °C TJ max; same M3 environmental grade | 0.8 mm height but no side-wettable flanks - AOI capability limited; lower peak pulse power (200 W) | Choose SMF15A for cost-sensitive consumer designs where 200 W surge rating suffices and AOI is not required |
Compared with SMAJ15A and SMF15A, the 6DFN15A-M3/H delivers superior board-area efficiency, lower clamping voltage, and full AOI support - making it optimal for space-constrained automotive and industrial modules requiring production-grade traceability and thermal performance.

FAQ
What is the exact breakdown voltage tolerance for 6DFN15A-M3/H?
The 6DFN15A-M3/H has a breakdown voltage tolerance of ±5 %, with a specified range of 14.3 V (min) to 15.8 V (max) at 1.0 mA test current. This tight tolerance ensures predictable clamping behavior across production lots and temperature extremes, directly supporting design margining for 12 V system interfaces.
Does 6DFN15A-M3/H meet AEC-Q101 qualification?
No - the 6DFN15A-M3/H carries the /H suffix in its ordering code, which denotes industry-grade qualification. AEC-Q101 qualified versions of this family use the /HE3 suffix (e.g., 6DFN15A-HE3). The 6DFN15A-M3/H is rated for industrial temperature range (–65 °C to +175 °C) and meets JESD201 Class 2 whisker testing, but is not AEC-Q101 certified.
What is the thermal resistance junction-to-ambient (RθJA) for 6DFN15A-M3/H on standard FR4?
The 6DFN15A-M3/H has a maximum RθJA of 175 °C/W when mounted on a standard FR4 PCB per JEDEC 51-2A guidelines. This value assumes a 2 oz. copper footprint matching the DFN3820A pad layout. Actual thermal performance improves significantly with added thermal vias or copper pour beneath the anode pad.
Can 6DFN15A-M3/H be used in bidirectional configurations?
No - the 6DFN15A-M3/H is explicitly unidirectional, as confirmed by its "A" polarity suffix and cathode-band marking. Bidirectional operation would require a dual-diode configuration or a dedicated bidirectional TVS such as the 6DFN15CA-M3/H. Using this part in reverse-biased AC signal paths risks permanent damage due to lack of reverse standoff capability.
What does the "M3" suffix indicate in 6DFN15A-M3/H?
The "M3" suffix in 6DFN15A-M3/H indicates halogen-free, RoHS-compliant, and Pb-free matte tin plating meeting JESD 201 Class 2 whisker resistance requirements. It also signifies industrial-grade material categorization per Vishay's compliance framework (document #99912), distinguishing it from automotive-grade variants.
