Product details
Overview
T6N36AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 36 V nominal breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 49.9 V clamping voltage at 12 A peak pulse current, 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the T6N36AHM3/H datasheet, T6N36AHM3/H pinout, T6N36AHM3/H application, or T6N36AHM3/H equivalent, this device supports high-temperature operation up to +185 °C, offers side-wettable flanks for AOI compatibility, and delivers precise transient suppression in space-constrained automotive sensor and powertrain signal lines.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive surge stress. Its unidirectional configuration enables robust protection of DC-biased signal paths without reverse conduction during normal operation.
The DFN3820A package provides 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 cathode band; heatsink serves as anode terminal.

FAQ
What is the breakdown voltage tolerance for T6N36AHM3/H?
The T6N36AHM3/H has a ±5 % breakdown voltage tolerance, confirmed by its "A" suffix in the part number and verified in the Electrical Characteristics table: VBR min/typ/max = 34.2 / 36.0 / 37.8 V at 1.0 mA test current. This tolerance ensures consistent clamping behavior across production lots and temperature ranges up to +185 °C.
Is T6N36AHM3/H compatible with lead-free reflow soldering processes?
Yes, T6N36AHM3/H is fully compatible with lead-free reflow soldering. It meets J-STD-020 MSL level 1 with a maximum peak temperature of 260 °C, and its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards. The DFN3820A package is qualified for standard Pb-free reflow profiles.
Does T6N36AHM3/H have a defined junction capacitance value?
Yes, the T6N36AHM3/H exhibits typical junction capacitance of <100 pF at VWM = 30.8 V, measured at 1.0 MHz with 50 mVp-p signal. This low capacitance is critical for protecting high-speed interfaces like CAN FD and LIN without signal distortion, as confirmed in Figure 4 of the datasheet.
How does the thermal resistance of T6N36AHM3/H compare to standard SMA packages?
T6N36AHM3/H achieves RθJM = 5 °C/W (typical), significantly lower than SMA-packaged alternatives (e.g., SMAJ36A: RθJM ≈ 15–20 °C/W). This is enabled by its exposed anode pad directly mounted to PCB copper, allowing efficient heat transfer to internal ground planes-essential for sustained surge duty cycles in automotive under-hood applications.
What does the "HM3" suffix indicate in T6N36AHM3/H?
The "HM3" suffix in T6N36AHM3/H denotes three key qualifications: H = AEC-Q101 qualified, M = halogen-free, and 3 = RoHS-compliant and Pb-free termination. This suffix confirms full compliance with automotive environmental and reliability standards, as explicitly stated in the Ordering Information Table and Mechanical Data section.
