Product details
Overview
T6N13AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 13.0 V nominal breakdown voltage (VBR), 11.1 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 T6N13AHM3/I datasheet, T6N13AHM3/I pinout, T6N13AHM3/I application, or T6N13AHM3/I equivalent, key selection criteria include its 185 °C junction temperature rating, side-wettable flanks for AOI compatibility, 0.88 mm low-profile height, and unidirectional clamping behavior with 18.2 V maximum clamping voltage at rated surge current.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and robust transient suppression. Its unidirectional configuration enables precise reverse-biased clamping without forward conduction during normal operation.
The DFN3820A package delivers low thermal resistance (RθJM = 5 °C/W typical) and supports automated placement with matte tin-plated terminals compliant to J-STD-002 and JESD 22-B102. Polarity is marked by a cathode band; the heatsink pad serves as the anode terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 13.0 V - Ensures reliable triggering above system operating voltage while maintaining margin against false clamping. |
| VWM | 11.1 V - Maximum continuous reverse voltage before leakage exceeds 2.0 μA, compatible with 12 V automotive supply rails. |
| IPPM (10/1000 μs) | 33.0 A - Sustains 600 W surge energy without degradation, sufficient for ISO 7637-2 Pulse 1/2a/5a compliance testing. |
| VC @ IPPM | 18.2 V - Clamping voltage limits protected IC stress to safe levels during transient events in CAN/LIN bus interfaces. |
| TJ max | 185 °C - Enables operation in under-hood environments without derating, supporting AEC-Q101 high-reliability requirements. |
| ESD immunity | ±30 kV (IEC 61000-4-2 contact discharge) - Provides robust protection for exposed sensor inputs in harsh automotive settings. |
| Package | DFN3820A - 3.95 mm × 2.18 mm footprint with side-wettable flanks for automated optical inspection and solder joint quality assurance. |

FAQ
What is the clamping voltage of the T6N13AHM3/I at its rated peak pulse current?
The T6N13AHM3/I exhibits a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPPM) of 33.0 A under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and ensures protected downstream components remain below their absolute maximum voltage ratings during surge events. The T6N13AHM3/I maintains this clamping performance across its full operating temperature range from -65 °C to +185 °C.
Is the T6N13AHM3/I suitable for use in AEC-Q101-compliant automotive designs?
Yes, the T6N13AHM3/I is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in datasheet 98432. It undergoes stress testing for high-temperature operating life, temperature cycling, and mechanical shock per AEC-Q101 requirements. The T6N13AHM3/I is approved for use in powertrain, chassis, and ADAS applications where zero-defect reliability is mandated.
How does the DFN3820A package of the T6N13AHM3/I support automated optical inspection (AOI)?
The DFN3820A package of the T6N13AHM3/I features side-wettable flanks-exposed metal on the vertical edges of the terminals-that enable reliable solder joint inspection using standard AOI systems without requiring X-ray. This design eliminates manual visual checks and reduces post-reflow defect escapes. The T6N13AHM3/I's 0.88 mm profile and precise dimensional tolerances further enhance placement yield in high-speed SMT lines.
What is the maximum junction temperature rating for the T6N13AHM3/I, and why is it significant?
The T6N13AHM3/I is rated for a maximum junction temperature (TJ) of +185 °C, significantly exceeding standard industrial-grade TVS diodes (typically 150 °C). This enables reliable operation in under-hood automotive environments such as engine control units and electric power steering modules. The T6N13AHM3/I sustains full electrical specifications-including 600 W peak pulse power-up to this temperature, ensuring consistent protection performance throughout vehicle service life.
Does the T6N13AHM3/I meet industry standards for electrostatic discharge immunity?
Yes, the T6N13AHM3/I achieves ±30 kV contact discharge and ±30 kV air discharge per IEC 61000-4-2, verified in Vishay's characterization testing. This level of ESD immunity makes the T6N13AHM3/I suitable for protecting sensitive analog and digital interfaces-including CAN, LIN, and sensor signal lines-in automotive and industrial equipment exposed to frequent human handling or environmental charge buildup.
