Product details
Overview
T6N36CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 36 V nominal breakdown voltage (±5 %), 30.8 V stand-off voltage, 49.9 V clamping voltage at 12 A, and 600 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and rated for TJ = 185 °C, designed for automotive sensor signal-line protection against inductive switching transients.
For engineers reviewing the T6N36CAHM3/H datasheet, T6N36CAHM3/H pinout, T6N36CAHM3/H application, or T6N36CAHM3/H equivalent, this page delivers verified electrical parameters, package dimensions, automotive-grade reliability data, and direct alternative part comparisons - all confirmed from Vishay's official documentation (Doc #98489, Rev. 17-Oct-2023).
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable bidirectional clamping under repetitive surge stress. Its DFN3820A package features side-wettable flanks for AOI compatibility and supports junction temperatures up to 185 °C - meeting stringent automotive thermal and reliability requirements.
The device operates as a single-element, unidirectional-capable bidirectional suppressor with no cathode marking. It delivers 49.9 V clamping at 12 A IPPM (10/1000 μs), with <1.0 μA reverse leakage at 30.8 V and 25 °C, and meets IEC 61000-4-2 ±30 kV ESD immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nom) | 36.0 V ±5 % - defines minimum voltage at which clamping initiates reliably under 1 mA test current |
| VWM | 30.8 V - maximum continuous working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 49.9 V at 12.0 A - clamping voltage during 10/1000 μs surge, limiting downstream IC stress |

| Industrial Motor Drive I/O | EV Battery Management Signal Lines |
Use Scenario: Shielding encoder feedback lines and digital I/Os in servo drives exposed to commutation noise and relay bounce. IC Role / Device Role / Timing Role: Fast-response transient suppressor mounted adjacent to connector entry points to prevent latch-up in FPGA or ASIC I/O banks. Use Value: Low 0.88 mm profile allows placement in space-constrained motor control PCBs; 1.0 μA leakage at 30.8 V ensures minimal impact on precision analog sensing. | Use Scenario: Protecting isolated communication lines (e.g., SPI, UART) between BMS master and cell monitoring ICs in high-voltage battery packs. IC Role / Device Role / Timing Role: Isolation-side TVS providing secondary surge protection after primary front-end filtering. Use Value: AEC-Q101 qualification and 185 °C rating ensure reliability in thermally demanding pack environments where ambient exceeds 105 °C. |
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-E3/57T | DO-214AC (SMA) package, 36 V unidirectional, 400 W PPPM, higher RθJA (190 °C/W) | Larger footprint, lower power rating, not AEC-Q101 qualified | Select when board space permits larger package and automotive qualification is not required |
| SMCJ36CA | DO-214AB (SMC) package, 36 V bidirectional, 1500 W PPPM, 2.4 mm height, non-AEC-Q101 | Higher surge capacity but incompatible with automated AOI due to lack of side-wettable flanks | Choose for industrial systems needing higher pulse power where AOI is not mandated |
Compared with SMAJ36A-E3/57T and SMCJ36CA, the T6N36CAHM3/H offers superior automotive compliance, compact DFN3820A packaging with AOI support, and optimized thermal performance (RθJM = 5 °C/W), making it the preferred choice for space- and reliability-critical automotive electronics.

FAQ
What is the clamping voltage of the T6N36CAHM3/H at its rated peak pulse current?
The T6N36CAHM3/H has a maximum clamping voltage (VC) of 49.9 V at 12.0 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 3 in Vishay's datasheet (Doc #98489) and ensures downstream ICs remain within safe operating voltage limits during surge events.
Is the T6N36CAHM3/H suitable for automotive applications?
Yes, the T6N36CAHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and whisker-resistant construction. Its 185 °C junction rating, MSL Level 1 moisture sensitivity, and ±30 kV ESD immunity make it fully suitable for automotive powertrain, body, and ADAS systems per ISO 16750 and LV-124 standards.
Does the T6N36CAHM3/H have polarity markings on the package?
No, the T6N36CAHM3/H is a bidirectional TVS diode and does not feature a cathode band or polarity marking. The DFN3820A package has two identical terminals; either can serve as anode or cathode depending on transient polarity, simplifying PCB layout and eliminating orientation errors during automated placement.
What is the thermal resistance from junction to mount (RθJM) for the T6N36CAHM3/H?
The T6N36CAHM3/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. This low value enables efficient heat transfer to the PCB copper pour, supporting sustained operation at elevated ambient temperatures without derating.
How does the DFN3820A package of the T6N36CAHM3/H support automated optical inspection?
The DFN3820A package of the T6N36CAHM3/H features side-wettable flanks - exposed metal on the vertical edges of the terminals - allowing AOI systems to verify solder joint quality on both top and bottom of the PCB without requiring X-ray inspection. This capability reduces post-reflow defect escape and improves manufacturing yield in high-volume automotive assembly.
