Product details
Overview
6DFN36A-M3/H from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, rated for 36 V nominal breakdown voltage (VBR = 34.2–37.8 V), 30.8 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 12.0 A peak pulse current (IPPM) and clamps to ≤49.9 V at that current, protecting MOSFETs and signal lines in industrial sensor interfaces.
For engineers reviewing the 6DFN36A-M3/H datasheet, 6DFN36A-M3/H pinout, 6DFN36A-M3/H application, or 6DFN36A-M3/H equivalent, key selection criteria include unidirectional clamping performance, low-profile DFN3820A footprint with side-wettable flanks for AOI, M3 halogen-free/RoHS compliance, and 175 °C maximum junction temperature suitability for high-reliability embedded systems.
Technical Context
This device implements an anisotropic rectifier structure with junction passivation optimized for fast transient response and stable clamping under repetitive surge conditions. Its unidirectional configuration provides asymmetric conduction-blocking reverse voltage up to VWM = 30.8 V while clamping positive transients above VBR = 36.0 V (typ.) with minimal leakage (≤1.0 μA at VWM).
Thermal design is enabled by low RθJM = 5 °C/W (typ.) to mounting pad and compatibility with JEDEC 51-14 TDIM testing. The DFN3820A package supports automated placement and meets MSL Level 1 (260 °C peak reflow), with polarity indicated by cathode band and anode connected to heatsink pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V - ensures reliable turn-on above system operating voltage while avoiding false triggering |
| VWM | 30.8 V - maximum continuous reverse voltage before significant leakage begins; matches 3.3 V or 5 V rail protection with margin |
| IPPM (10/1000 μs) | 12.0 A - peak surge current capability enabling robust protection against IEC 61000-4-4 EFT and inductive switching spikes |
| VC @ IPPM | ≤49.9 V - clamping voltage limits stress on downstream ICs during worst-case transients |
| TJ max | +175 °C - supports operation in high-temperature industrial enclosures without derating |
| ESD immunity | ±30 kV contact/air per IEC 61000-4-2 - protects against human-body-model electrostatic discharge events |
| RθJM | 5 °C/W (typ.) - enables efficient heat transfer to PCB copper pour, critical for sustained surge handling |
Pinout & Package
Package: DFN3820A - 2-terminal, leadless, low-profile (0.88 mm typical height) surface-mount package with side-wettable flanks for automated optical inspection (AOI) and solder joint quality verification. Cathode marked by color band; anode connected to exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (thermal pad) | Current return path and thermal interface | Must be soldered to ≥100 mm² copper pour for RθJM optimization and surge energy dissipation |
| Cathode (marked pin) | Transient voltage sensing and clamping node | Connected to protected line (e.g., sensor output); conducts only during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection of solder fillet integrity without X-ray, reducing post-reflow defect escape |
| Unidirectional clamping | Prevents forward conduction during normal operation while providing precise positive transient suppression |
| Low-profile DFN3820A | 0.88 mm height allows use in space-constrained modules (e.g., IoT edge sensors, automotive ECUs) without mechanical interference |
| M3 material grade | Halogen-free, RoHS-compliant, Pb-free terminations with JESD 201 Class 2 whisker resistance for long-term reliability |
| MSL Level 1 rating | Supports standard SMT reflow profiles up to 260 °C peak without preconditioning, simplifying manufacturing flow |
Applications
| Industrial Sensor Protection | Automotive Body Control Module |

Use Scenario: Protecting analog output lines (4–20 mA, 0–10 V) of pressure/temperature sensors in factory automation cabinets exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Transient voltage suppressor placed directly at sensor connector entry point to shunt induced surges before reaching ADC input or signal conditioner. Use Value: Clamps 600 W surges to ≤49.9 V, preventing latch-up or damage to precision op-amps and SAR ADCs operating at ±15 V rails. |
Use Scenario: Safeguarding LIN bus transceiver I/O pins and microcontroller GPIOs in door module ECUs subject to load dump and ISO 7637-2 pulse 1/2a/3a. IC Role / Device Role / Timing Role: Unidirectional TVS mounted adjacent to connector, referenced to chassis ground, absorbing negative-going transients on supply and signal lines. Use Value: Withstands 30 kV ESD per IEC 61000-4-2 and maintains <1.0 μA leakage at 30.8 V, preserving sleep-mode current budget. |
| Medical Patient Monitoring Interface | Telecom Power Supply Input |
|
Use Scenario: Shielding isolated analog front-end inputs (ECG, SpO₂) from ESD and defibrillator-induced transients in portable monitors. IC Role / Device Role / Timing Role: Primary transient clamp on non-isolated side of signal chain, coordinated with secondary protection on isolated side. Use Value: Low capacitance (<50 pF at VWM, per Fig. 4) avoids signal distortion in DC-coupled biopotential amplifiers. |
Use Scenario: Front-end surge suppression on 48 V telecom power distribution boards subjected to lightning-induced surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Secondary-level protector downstream of MOV/GDT primary stages, handling residual fast-rising transients. Use Value: 600 W (10/1000 μs) rating and 12.0 A IPPM provide defined energy-handling margin when cascaded with upstream protectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | DO-214AC package (SMA), higher RθJA = 50 °C/W, same VBR/VWM specs but 1.5× larger footprint | Preferred where manual rework or legacy through-hole-compatible layout exists; unsuitable for ultra-thin designs | Select SMAJ36A only if board thickness constraints allow >2.0 mm height or AOI is not required. |
| SMCJ36A | DO-214AB (SMC) package, 1500 W rating, 2× IPPM (24.7 A), but 3× larger area and 2.2 mm height | Better suited for primary-level AC/DC input protection; over-specified for signal-line clamping | Choose SMCJ36A when surge threat level exceeds 1000 W or when PCB space permits larger discrete TVS. |
Compared with SMAJ36A and SMCJ36A, the 6DFN36A-M3/H offers superior board-area efficiency and AOI-ready manufacturability in compact, high-density layouts-critical for next-gen sensor nodes and modular ECUs-while maintaining identical electrical clamping performance at 36 V.

FAQ
What is the exact breakdown voltage range for 6DFN36A-M3/H?
The 6DFN36A-M3/H has a guaranteed breakdown voltage (VBR) range of 34.2 V (min) to 37.8 V (max) at test current IT = 1.0 mA, with nominal value 36.0 V. This tolerance (±5 %) is confirmed in the Electrical Characteristics table of Vishay document 98464, revision 10-Nov-2023.
Does 6DFN36A-M3/H meet AEC-Q101 qualification?
No, the 6DFN36A-M3/H does not carry AEC-Q101 qualification. Its ordering code suffix "H" refers to tape-and-reel packaging (7″ diameter), not automotive qualification. The "H" in the package code column denotes delivery mode-not reliability grade. Automotive-grade variants in this family use different suffixes (e.g., "HE3" or "HM3").
What is the thermal resistance from junction to mount (RθJM) for 6DFN36A-M3/H?
The 6DFN36A-M3/H has a typical junction-to-mount thermal resistance RθJM of 5 °C/W, measured per JEDEC 51-14 using the Transient Dual Interface Method (TDIM). Maximum specified value is 6.5 °C/W. This enables effective heat transfer to the PCB thermal pad under surge conditions.
Can 6DFN36A-M3/H be used in bidirectional protection configurations?
No, the 6DFN36A-M3/H is strictly unidirectional. Its internal structure and polarity marking (cathode band) confirm single-quadrant clamping behavior. For bidirectional protection, Vishay specifies separate part numbers such as 6DFN36CA ('C' denotes bidirectional), which is not interchangeable with 6DFN36A-M3/H.
What is the maximum reverse leakage current of 6DFN36A-M3/H at 25 °C and VWM?
At TA = 25 °C and applied reverse voltage equal to its stand-off voltage VWM = 30.8 V, the 6DFN36A-M3/H exhibits maximum reverse leakage current IR of 1.0 μA. This value is specified in the Electrical Characteristics table and verified per JEDEC test conditions.
