Product details
Overview
T6N36AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 36 V nominal breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 49.9 V clamping voltage at 12.0 A peak pulse current, and 600 W peak pulse power rating (10/1000 μs). It operates from -65 °C to +185 °C and is AEC-Q101 qualified for automotive sensor line protection.
For engineers reviewing the T6N36AHM3/I datasheet, T6N36AHM3/I pinout, T6N36AHM3/I application, or T6N36AHM3/I equivalent, this device delivers high-temperature stability, side-wettable flanks for AOI compatibility, and validated surge immunity per IEC 61000-4-2 (±30 kV contact/air discharge) - critical for robust ESD and load-switch transient protection in automotive ECUs and ADAS sensor interfaces.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive transients. Its unidirectional configuration enables precise reverse-biased protection of signal lines referenced to ground, while the DFN3820A package provides low thermal resistance (RθJM = 5 °C/W typical) for reliable power dissipation during 10/1000 μs surges.
The device exhibits a positive temperature coefficient of breakdown voltage (αT = 0.090 %/°C), enabling predictable VBR drift over temperature, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak - confirming suitability for high-volume automated SMT assembly without moisture sensitivity concerns.
