Product details
Overview
T6N82CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 77.9 V minimum breakdown voltage, 70.1 V stand-off voltage, and 113 V maximum clamping voltage at 5.3 A peak pulse current. It delivers 600 W peak pulse power (10/1000 μs), supports TJ = 185 °C operation, and is AEC-Q101 qualified for automotive sensor line protection.
For engineers reviewing the T6N82CAHM3/I datasheet, T6N82CAHM3/I pinout, T6N82CAHM3/I application, or T6N82CAHM3/I equivalent, this page provides verified electrical parameters, package dimensions, clamping behavior under surge, thermal resistance values, and AEC-Q101 qualification evidence - all critical for ESD/surge co-design in automotive ECUs and ADAS sensor interfaces.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable bidirectional clamping with low leakage (<1 μA at VWM) across -65 °C to +185 °C junction temperature range. Its DFN3820A package features side-wettable flanks for AOI-compatible solder joint inspection and meets MSL Level 1 (260 °C peak reflow).
The device operates as a single-channel, unidirectional-capable bidirectional clamp - no cathode marking - with 140 °C/W typical junction-to-ambient thermal resistance on FR4 and 5 °C/W junction-to-mount resistance per JEDEC 51-14. It withstands 30 kV contact/air discharge per IEC 61000-4-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min) | 77.9 V - ensures reliable conduction onset above normal 70.1 V operating bus voltage |
| VWM | 70.1 V - maximum continuous reverse voltage before leakage exceeds 1 μA |
| VC @ IPPM | 113 V - clamping voltage at 5.3 A surge limits downstream IC stress during 10/1000 μs transients |
| PPPM | 600 W - peak power handling capacity for standardized lightning/inductive-switching surges |
| TJ max | +185 °C - enables placement near high-temperature engine bay components without derating |
| ESD Rating | 30 kV contact/air - exceeds IEC 61000-4-2 Level 4 for robust board-level ESD immunity |
| RθJA | 140 °C/W - defines thermal rise on standard FR4; requires layout-aware copper pour for sustained surge duty |
Pinout & Package
DFN3820A package: 2-terminal, symmetrical, leadless, halogen-free, RoHS-compliant, with side-wettable flanks (0.35 mm ±0.05 mm flank height). Dimensions: 3.95 mm × 2.18 mm × 0.88 mm (L × W × H), 0.70 mm pitch between terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Non-polarized connection point - identical electrical behavior in either orientation |
| Terminal 2 | Anode/Cathode (bidirectional) | Paired terminal forming symmetric clamping path; no polarity marking required |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| Side-wettable flanks | Supports automated optical inspection (AOI) of solder fillets - critical for automotive zero-defect manufacturing |
| AEC-Q101 qualification | Validated reliability for automotive underhood applications including temperature cycling, HTRB, and mechanical shock |
| 185 °C junction rating | Permits direct mounting on high-thermal-load PCB areas (e.g., near power MOSFETs or DC/DC converters) |
| Low-profile height (0.88 mm) | Reduces system Z-height in space-constrained modules such as radar front-ends and camera ECU housings |
Applications
| Automotive Sensor Signal Lines | ADAS Camera Power Input |
|---|---|
Use Scenario: Protecting LIN/CAN physical layer signal traces in door module ECUs from load-dump and ESD events. IC Role / Device Role / Timing Role: Bidirectional transient clamp placed directly at connector interface before signal conditioning IC. Use Value: Limits induced transients to ≤113 V, preventing latch-up or gate oxide damage in 3.3 V/5 V interface ICs while maintaining <1 μA leakage at 70.1 V nominal bus. | Use Scenario: Safeguarding 12 V input rail of CMOS image sensor modules against ISO 7637-2 Pulse 5a (load dump) surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of DC/DC converter input, absorbing up to 600 W for 1 ms. Use Value: Clamps 12 V rail to 113 V during 10/1000 μs surge, enabling use of lower-voltage-rated input capacitors and reducing BOM cost vs. higher-VBR alternatives. |
| Engine Control Unit (ECU) Analog Inputs | Electric Power Steering (EPS) Motor Driver Feedback |
Use Scenario: Shielding analog sensor inputs (e.g., throttle position, coolant temp) from ignition coil switching noise. IC Role / Device Role / Timing Role: Low-capacitance TVS placed at ADC input filter node to suppress fast-rising transients without distorting signal integrity. Use Value: Maintains <1 μA leakage at 70.1 V, avoiding DC offset errors in precision ratiometric measurements while clamping sub-μs spikes to safe levels. | Use Scenario: Protecting Hall-effect rotor position feedback lines in EPS motor drivers from commutation-induced voltage spikes. IC Role / Device Role / Timing Role: Bidirectional clamp on differential feedback pair, preserving common-mode rejection during high-dV/dt events. Use Value: Symmetric clamping ensures equal voltage limiting on both lines, preventing common-mode excursion beyond ADC input range and avoiding false fault detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ85CA | DO-214AC package; 85 V VBR min; 600 W PPPM; 150 °C TJ max; not AEC-Q101 qualified | Higher profile (2.3 mm), no side-wettable flanks - unsuitable for AOI or high-density automotive PCBs | Select when cost sensitivity outweighs automotive qualification and AOI requirements |
| SMCJ85CA | DO-214AB package; same VBR/PPPM; 175 °C TJ max; AEC-Q101 qualified; larger footprint (7.11 mm × 6.22 mm) | Higher thermal mass but 3× larger area - viable where board space permits and higher IPPM margin needed | Select when higher surge current handling (10.5 A vs. 5.3 A) and legacy through-hole compatibility are priorities |
Compared with SMAJ85CA and SMCJ85CA, T6N82CAHM3/I offers the only combination of AEC-Q101 qualification, DFN3820A miniaturization, side-wettable flanks for process control, and 185 °C operation - making it uniquely suited for next-generation compact, high-reliability automotive electronics where board area, manufacturability, and underhood thermal margins are constrained.

FAQ
What is the breakdown voltage tolerance for T6N82CAHM3/I?
The T6N82CAHM3/I has a ±5 % breakdown voltage tolerance, confirmed by its "CA" suffix per Vishay's ordering nomenclature. The datasheet specifies minimum VBR = 77.9 V, nominal = 82.0 V, and maximum = 86.1 V at 1.0 mA test current - ensuring predictable turn-on behavior across production lots and temperature ranges.
Is T6N82CAHM3/I compatible with lead-free reflow processes?
Yes, T6N82CAHM3/I is fully compatible with lead-free reflow. It meets J-STD-020 MSL Level 1 with a maximum peak temperature of 260 °C, and its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards. The HM3 suffix also confirms JESD 201 Class 2 whisker resistance.
Does T6N82CAHM3/I require a heatsink for 600 W surge handling?
No external heatsink is required for single-event 600 W (10/1000 μs) surge handling, as the energy is dissipated within the silicon junction before significant heat spreads to the ambient. However, repeated surges demand attention to RθJA = 140 °C/W and PCB copper area - the DFN3820A package relies on thermal conduction through the mount pad, not airflow.
How does the bidirectional nature of T6N82CAHM3/I affect circuit placement?
The bidirectional design of T6N82CAHM3/I eliminates polarity constraints: it can be placed across any two nodes needing transient suppression regardless of DC bias direction. This simplifies layout in AC-coupled sensor lines or floating differential pairs, and removes risk of incorrect orientation during automated placement - no cathode band marking is present.
What is the junction capacitance of T6N82CAHM3/I at 0 V bias?
T6N82CAHM3/I exhibits typical junction capacitance of ~100 pF at 0 V bias, as inferred from the family's Fig. 4 curve (CJ vs. VBR) showing ~100 pF at 82 V VBR. This value is appropriate for low-speed signal lines (e.g., LIN, analog sensors) but may limit use in >10 MHz digital interfaces without additional filtering.
