Product details
Overview
T6N22AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 22.0 V nominal breakdown voltage (VBR), 18.8 V stand-off voltage (VWM), 30.6 V maximum clamping voltage at 19.6 A peak pulse current, and 600 W peak pulse power rating (10/1000 μs). It is AEC-Q101 qualified, rated for TJ = 185 °C, and designed for automotive sensor signal-line protection against load-switching transients and ESD.
For engineers reviewing the T6N22AHM3/H datasheet, T6N22AHM3/H pinout, T6N22AHM3/H application, or T6N22AHM3/H equivalent, this page delivers verified electrical parameters, thermal performance data, AOI-compatible packaging details, and validated automotive-grade alternatives - all specific to the T6N22AHM3/H variant with HM3 halogen-free, RoHS-compliant, whisker-tested construction.
Technical Context
The T6N22AHM3/H employs passivated anisotropic rectifier technology optimized for low-leakage, high-clamping-efficiency transient suppression. Its unidirectional configuration provides precise reverse-biased standoff with 1.0 μA max reverse leakage at VWM, enabling robust protection of sensitive IC inputs without DC loading.
Thermally, it achieves RθJM = 5 °C/W (typ) junction-to-mount and supports continuous operation up to 185 °C junction temperature. It meets IEC 61000-4-2 ±30 kV contact/air discharge and MSL Level 1 reflow compatibility (260 °C peak).

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22AHE3/5BT | DO-214AC (SMA) package; 22 V VBR; 35.5 V VC @ 17.1 A; RθJA = 50 °C/W (vs. 140 °C/W for T6N22AHM3/H) | Higher profile (2.3 mm height); no AEC-Q101 qualification; suited for non-automotive industrial PCBs | Select when legacy SMA footprint exists and automotive qualification is not required |
| TPSMD22AH | TO-277A package; 22 V VBR; 35.0 V VC @ 17.1 A; TJ max = 175 °C; AEC-Q101 qualified | Larger footprint (5.3 mm × 2.9 mm); higher thermal mass but lower power density than DFN3820A | Prefer when higher surge repetition rate or manual rework accessibility is needed |

FAQ
What is the exact breakdown voltage range for T6N22AHM3/H?
The T6N22AHM3/H has a guaranteed breakdown voltage range of 20.9 V (min) to 23.1 V (max) at 1.0 mA test current, with 22.0 V nominal. This ±5 % tolerance (denoted by "A" in the part number) ensures predictable clamping onset across production lots and temperature extremes up to 150 °C.
Is T6N22AHM3/H compatible with standard SMT reflow profiles?
Yes, the T6N22AHM3/H is rated for MSL Level 1 per J-STD-020 and withstands a maximum peak reflow temperature of 260 °C. Its DFN3820A package uses matte tin-plated terminals qualified to J-STD-002 and JESD 22-B102, supporting industry-standard lead-free reflow processes without delamination or solder joint failure.
Does T6N22AHM3/H meet automotive qualification standards?
Yes, the T6N22AHM3/H carries the HM3 suffix indicating full AEC-Q101 qualification. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per IEC 61000-4-2 - all documented in Vishay's qualification report for the T6NxxA family.
What is the thermal resistance from junction to mount for T6N22AHM3/H?
The T6N22AHM3/H has a typical junction-to-mount thermal resistance (RθJM) of 5 °C/W, measured using JEDEC® 51-14 transient dual interface method. This low value enables efficient heat transfer to the PCB copper pour, critical for sustaining repeated 600 W surges in compact automotive modules.
How does the clamping voltage of T6N22AHM3/H compare to similar 22 V TVS devices?
The T6N22AHM3/H clamps to 30.6 V at its rated 19.6 A peak pulse current (10/1000 μs), which is 1.39× VWM. This ratio is tighter than many competing 22 V TVS diodes (e.g., SMAJ22AHE3/5BT clamps at 35.5 V), delivering superior protection margin for 3.3 V and 5 V logic interfaces.
