Product details
Overview
T6N16AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability. It protects MOSFETs and sensor signal lines against inductive switching transients and lightning surges in engine control units and ADAS modules.
For engineers reviewing the T6N16AHM3/I datasheet, T6N16AHM3/I pinout, T6N16AHM3/I application, or T6N16AHM3/I equivalent, key selection criteria include its 185 °C junction temperature rating, side-wettable flanks for AOI compatibility, 22.5 V clamping voltage at 26.7 A peak pulse current, and halogen-free RoHS-compliant construction with HM3 suffix.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for high-temperature stability. Its unidirectional configuration enables precise clamping on positive-going transients while maintaining low leakage (<1.0 μA at VWM) across -65 °C to +185 °C operating range.
The DFN3820A package delivers thermal resistance of 5 °C/W (junction-to-mount) and supports automated placement with solderable matte tin terminals compliant to J-STD-002 and JESD 22-B102. It meets MSL Level 1 and JESD 201 Class 2 whisker test requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-HF | DO-214AC package; higher RθJA (190 °C/W); 23.5 V VC at 25.8 A | Larger footprint; unsuitable for AOI; lower thermal performance in confined spaces | Choose when legacy through-hole or larger board area is acceptable and AEC-Q101 not required |
| TPSMF16A | SOD-123FL package; 22.0 V VC at 27.3 A; same VBR tolerance but no side-wettable flanks | No AOI support; lower thermal resistance to mount (RθJM = 7.5 °C/W); not AEC-Q101 qualified | Prefer for cost-sensitive industrial designs where automotive qualification and AOI are not mandatory |
Compared with SMAJ16A-HF and TPSMF16A, the T6N16AHM3/I offers superior thermal management (RθJM = 5 °C/W), automated optical inspectability, and full AEC-Q101 compliance-making it the only option qualified for safety-critical automotive power domains requiring zero visual solder defects and extended temperature operation.

FAQ
What is the clamping voltage of the T6N16AHM3/I at its rated peak pulse current?
The T6N16AHM3/I has a maximum clamping voltage (VC) of 22.5 V at its rated peak pulse current (IPPM) of 26.7 A under 10/1000 μs waveform conditions. This value ensures protection of 15 V-rated downstream components such as microcontrollers and interface ICs. The clamping performance is validated across the full operating temperature range up to +185 °C junction temperature.
Is the T6N16AHM3/I qualified for automotive applications?
Yes, the T6N16AHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and lead-free construction. It is specifically designed for automotive environments, supporting operation from -65 °C to +185 °C and passing rigorous stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD per IEC 61000-4-2.
What does the "HM3" suffix mean in T6N16AHM3/I?
The "HM3" suffix in T6N16AHM3/I denotes Vishay's material/environment category: halogen-free, RoHS-compliant, Pb-free termination, and qualified to JESD 201 Class 2 for tin whisker resistance. It also confirms AEC-Q101 qualification and compatibility with standard SMT reflow profiles up to 260 °C peak temperature (MSL Level 1).
Can the T6N16AHM3/I be used in place of a SMAJ16A in an existing design?
No direct replacement: T6N16AHM3/I uses DFN3820A (3.95 mm × 2.18 mm), while SMAJ16A uses DO-214AC (4.5 mm × 2.7 mm). Layout changes are required. Additionally, T6N16AHM3/I offers superior thermal resistance (RθJM = 5 °C/W vs. ~190 °C/W), side-wettable flanks for AOI, and AEC-Q101 qualification-features absent in SMAJ16A.
What is the maximum reverse leakage current of the T6N16AHM3/I at 13.6 V and 150 °C?
The T6N16AHM3/I exhibits a maximum reverse leakage current (ID) of 1.0 μA at VWM = 13.6 V and TJ = 150 °C, as specified in the Vishay datasheet (Document Number: 98432). This low leakage ensures minimal impact on bias networks and sensor reference accuracy in high-temperature automotive environments.
