Product details
Overview
T6N100CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, rated for 100 V breakdown voltage (VBR), 85.5 V working voltage (VWM), and 600 W peak pulse power (10/1000 μs), designed to protect automotive sensor signal lines and MOSFET gates against lightning-induced transients and inductive switching surges.
For engineers reviewing the T6N100CAHM3/I datasheet, T6N100CAHM3/I pinout, T6N100CAHM3/I application, or T6N100CAHM3/I equivalent, key selection criteria include AEC-Q101 qualification, 185 °C junction temperature rating, side-wettable flanks for AOI compatibility, and clamping voltage of 137 V at 4.4 A IPPM - critical for high-reliability automotive ECU and ADAS front-end protection.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for stable performance under thermal stress. Its bidirectional configuration enables symmetrical clamping without polarity constraints, and its DFN3820A footprint supports automated placement while meeting MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
The device delivers 600 W surge capability per 10/1000 μs waveform with a maximum clamping voltage of 137 V at 4.4 A peak pulse current. Thermal resistance is specified as RθJA = 175 °C/W (max) and RθJM = 6.5 °C/W (max), enabling reliable operation up to +185 °C junction temperature in compact automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 95.0 / 100 / 105 V - ensures precise overvoltage triggering above system nominal rail |
| VWM | 85.5 V - defines maximum continuous reverse operating voltage before leakage rises |
| IPPM (10/1000 μs) | 4.4 A - peak surge current the device safely clamps without failure |

Applications
| Automotive Sensor Protection | Power Supply Rail Clamping |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses in body control modules. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed directly at connector interface to shunt surge energy before reaching IC pins. Use Value: Clamps 137 V at 4.4 A while maintaining 85.5 V stand-off - prevents latch-up and gate oxide damage in 5 V/12 V sensor interfaces. | Use Scenario: Safeguarding 12 V/24 V power rails feeding microcontrollers and PMICs in infotainment head units and telematics control units. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing repetitive switching transients from DC-DC converter output stages. Use Value: 600 W peak pulse rating and 185 °C TJ max ensure sustained protection across vehicle lifetime without parameter drift. |
| MOSFET Gate Protection | ADAS Radar Front-End Protection |
Use Scenario: Shielding high-side/low-side N-channel MOSFET gates in motor drivers and LED matrix controllers from Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Low-capacitance TVS placed between gate and source to clamp sub-100 ns transients without affecting switching speed. Use Value: 137 V clamping voltage limits gate-source stress below 20 V rating of common automotive logic-level MOSFETs. | Use Scenario: Guarding RF front-end components (LNAs, mixers) in 77 GHz radar modules against ESD and antenna-coupled transients. IC Role / Device Role / Timing Role: First-line defense at RF connector entry point, minimizing parasitic inductance via DFN3820A's short internal path. Use Value: Side-wettable flanks ensure robust solder joint integrity under vibration - critical for radar module field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100CA | DO-214AC package (SMA), 100 V VBR, 600 W, but 150 °C TJ max and no AEC-Q101 qualification | Lacks automotive qualification and side-wettable flanks; requires manual AOI workaround | Select when cost sensitivity outweighs automotive compliance and AOI needs |
| SMCJ100CA | DO-214AB package (SMC), 100 V VBR, 1500 W rating, but 10.3 mm × 7.1 mm footprint and 150 °C TJ | Higher power but incompatible with space-constrained automotive PCBs; no MSL Level 1 rating | Choose only for non-automotive industrial systems requiring >1 kW surge handling |
Compared with SMAJ100CA and SMCJ100CA, the T6N100CAHM3/I uniquely combines AEC-Q101 qualification, 185 °C operation, side-wettable flanks, and DFN3820A's 3.95 mm × 2.18 mm footprint - making it the only option qualified for next-generation automotive ECUs where board area, thermal margin, and automated inspection are co-constrained.

FAQ
What is the maximum clamping voltage of the T6N100CAHM3/I at its rated peak pulse current?
The T6N100CAHM3/I has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current (IPPM) of 4.4 A under a 10/1000 μs waveform. This value is measured per IEC 61000-4-5 test conditions and ensures downstream ICs remain within safe voltage margins during surge events. The T6N100CAHM3/I maintains this clamping performance across its full operating temperature range.
Is the T6N100CAHM3/I qualified for automotive applications?
Yes, the T6N100CAHM3/I is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HM3". It meets all stress tests required for automotive-grade discrete components, including high-temperature reverse bias, temperature cycling, and mechanical shock. The T6N100CAHM3/I is explicitly intended for use in engine control units, body electronics, and ADAS systems.
Does the T6N100CAHM3/I have polarity markings on the package?
No, the T6N100CAHM3/I is a bidirectional TVS diode and carries no cathode band or polarity marking on the DFN3820A package. Both terminals are functionally identical, allowing either orientation during PCB placement. This simplifies layout and eliminates risk of incorrect orientation during automated assembly - a key advantage of the T6N100CAHM3/I in high-volume automotive manufacturing.
What is the thermal resistance junction-to-ambient (RθJA) for the T6N100CAHM3/I?
The T6N100CAHM3/I has a maximum RθJA of 175 °C/W when mounted on a standard FR4 PCB per JEDEC 51-2A. Its typical RθJA is 140 °C/W. This thermal performance, combined with a +185 °C maximum junction temperature, allows the T6N100CAHM3/I to sustain repeated surge events in thermally constrained automotive environments without thermal runaway.
How does the DFN3820A package of the T6N100CAHM3/I support automated optical inspection (AOI)?
The T6N100CAHM3/I's DFN3820A package features side-wettable flanks - exposed copper terminations along the package edges that form visible solder fillets during reflow. This geometry enables standard AOI systems to inspect solder joint quality without requiring X-ray, reducing final-test cost and improving yield in automotive electronics production. The T6N100CAHM3/I was designed specifically to meet this requirement.
