Product details
Overview
T6N15AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, rated for 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 28.3 A peak pulse current and clamps to 21.2 V at rated surge, with AEC-Q101 qualification and 185 °C maximum junction temperature - deployed for automotive sensor line protection against inductive switching transients.
For engineers reviewing the T6N15AHM3/I datasheet, T6N15AHM3/I pinout, T6N15AHM3/I application, or T6N15AHM3/I equivalent, key selection criteria include its unidirectional DFN3820A footprint, 0.88 mm profile for space-constrained PCBs, side-wettable flanks for AOI compatibility, and validated 30 kV IEC 61000-4-2 ESD immunity - critical for automotive-grade signal-line transient suppression.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation. Its unidirectional configuration provides low-leakage reverse blocking (1.0 μA at VWM) and precise clamping response under fast-rising transients.
The DFN3820A package enables thermal resistance of 5 °C/W junction-to-mount (RθJM) 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.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 14.3 / 15.0 / 15.8 V - ensures reliable turn-on above system operating voltage while avoiding false triggering |
| VWM | 12.8 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA, matching 12 V automotive supply rails |
| IPPM | 28.3 A - peak surge current capability under 10/1000 μs waveform, sufficient for ISO 7637-2 Pulse 1/2a/5a compliance |
| VC @ IPPM | 21.2 V - clamping voltage limiting protected IC/MOSFET stress during surge events |
| TJ max | +185 °C - enables operation in under-hood automotive environments without derating |
| ESD immunity | 30 kV contact/air per IEC 61000-4-2 - eliminates need for additional ESD protection on sensor interfaces |
| Package | DFN3820A - 3.95 mm × 2.18 mm × 0.88 mm footprint with side-wettable flanks for solder joint inspection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15AHE3/5BT | DO-214AC (SMA) package; higher RθJA (150 °C/W); 15 V VBR, 600 W rating | Larger footprint (4.5 × 2.7 mm); unsuitable for ultra-thin modules; requires manual AOI or X-ray | Select when legacy SMA layout exists or thermal constraints permit larger package |
| TPSMD15H | DO-214AB (SMC) package; 15 V VBR; 600 W; AEC-Q101 qualified; 1.1 mm height | Higher profile (1.1 mm vs. 0.88 mm); no side-wettable flanks; less suitable for automated optical inspection | Choose if existing SMC footprint is fixed and AOI capability is not required |
Compared with SMAJ15AHE3/5BT and TPSMD15H, the T6N15AHM3/I offers superior board-space efficiency, AOI-ready terminations, and lower thermal resistance to mount - making it optimal for next-generation automotive ECUs where height, inspection reliability, and thermal performance are prioritized.

FAQ
What is the breakdown voltage tolerance for T6N15AHM3/I?
The T6N15AHM3/I has a ±5 % breakdown voltage tolerance, specified as 14.3 V (min) to 15.8 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise design margins in 12 V automotive systems where overvoltage thresholds must be tightly controlled relative to IC absolute maximum ratings.
Is T6N15AHM3/I compatible with lead-free reflow processes?
Yes, T6N15AHM3/I is fully compatible with lead-free reflow processes, meeting JEDEC J-STD-020 MSL Level 1 with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, and the halogen-free molding compound satisfies RoHS and ELV requirements - enabling use in standard Pb-free assembly lines without process modification.
Does T6N15AHM3/I require a heatsink pad connection?
Yes, the anode terminal of T6N15AHM3/I is implemented as an exposed metal pad (heatsink) that must be soldered to a PCB copper pour for thermal and electrical performance. This connection achieves RθJM = 5 °C/W and provides the primary current return path; omitting it degrades surge current handling and risks thermal runaway during repeated transients.
How does T6N15AHM3/I perform at elevated ambient temperatures?
T6N15AHM3/I maintains full 600 W peak pulse power capability up to 25 °C ambient; above that, power derates linearly per Figure 2 in the datasheet, reaching ~400 W at 100 °C ambient. Its 185 °C TJmax allows operation in under-hood environments where case temperatures exceed 125 °C - verified through AEC-Q101 high-temperature reverse bias testing.
What is the polarity marking convention for T6N15AHM3/I?
T6N15AHM3/I uses a color band (typically black or dark gray) on the cathode end of the DFN3820A package to indicate polarity. The opposite end - the exposed metal pad - is the anode and must be connected to the reference plane (e.g., ground or power rail). This marking aligns with IPC-7351 standards and is visible under standard AOI systems due to side-wettable flank geometry.
