Product details
Overview
T6N15AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 15.0 V nominal breakdown voltage (VBR), 12.8 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.
For engineers reviewing the T6N15AHM3/H datasheet, T6N15AHM3/H pinout, T6N15AHM3/H application, or T6N15AHM3/H equivalent, this page delivers verified electrical parameters, thermal performance at TJ = 185 °C, side-wettable flank geometry for AOI, and direct AEC-Q101-compliant use 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 high-temperature operation up to 185 °C. Its unidirectional configuration enables precise reverse-biased transient suppression on positive-going voltage rails.
The DFN3820A package provides low thermal resistance (RθJM = 5 °C/W typical) and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It delivers 21.2 V maximum clamping voltage (VC) at 5.0 A IPPM, enabling robust protection of 12 V automotive electronics without overvoltage stress on downstream ICs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 14.3 / 15.0 / 15.8 V - ensures reliable triggering above 12.8 V system stand-off while avoiding false trips during normal operation |
| VWM | 12.8 V - defines maximum continuous reverse operating voltage compatible with 12 V automotive supply rails |
| IPPM (10/1000 μs) | 5.0 A - peak surge current capability sufficient to absorb ISO 7637-2 Pulse 1/2a/5a transients in body control modules |
| VC @ IPPM | 21.2 V - clamping voltage limits protected circuit stress to safe levels below typical 24 V tolerant interface IC thresholds |
| TJ max | +185 °C - supports under-hood placement in engine management systems without derating loss |
| ESD immunity | ±30 kV contact/air per IEC 61000-4-2 - eliminates need for secondary ESD protection on sensor input traces |
| Package | DFN3820A (3.95 mm × 2.18 mm × 0.88 mm) - enables high-density layout with side-wettable flanks for automated optical inspection |
Pinout & Package
DFN3820A package with two terminals: anode (heatsink pad) and cathode (marked side). The exposed thermal pad serves as the anode connection and must be soldered to a PCB copper pour for optimal thermal dissipation and clamping performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (exposed pad) | Power return path and thermal interface | Must be connected to large PCB copper area to achieve RθJM = 5 °C/W and sustain 600 W pulse power |
| Cathode (marked side) | Transient voltage sensing and clamping node | Connected to protected line; color band identifies polarity for correct orientation during automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables 100 % automated optical inspection (AOI) of solder joint integrity on both lateral edges of DFN package |
| AEC-Q101 qualification | Validated for automotive applications including powertrain, chassis, and ADAS with zero defects in HTOL, TC, and UHAST testing |
| Junction passivation | Prevents parametric drift and leakage increase after 1000 h at 150 °C, ensuring long-term clamping stability |
| Halogen-free & RoHS | Meets automotive material compliance requirements (JESD201 Class 2 whisker test, UL 94 V-0 molding compound) |
| Low-profile height | 0.88 mm max profile allows integration beneath connectors and in space-constrained sensor housings |
Applications

Use Scenario: Shielding capacitive touch and pressure sensor analog front-ends from ESD events during vehicle assembly and service. IC Role / Device Role / Timing Role: Connected inline with sensor supply and output lines to divert ±30 kV ESD strikes per IEC 61000-4-2 before reaching precision amplifier stages. Use Value: Sub-1 μA leakage at 12.8 V preserves sensor bias accuracy and extends battery life in always-on occupancy detection circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/57T | DO-214AC package (SMA), 15 V VBR, 24.4 V VC @ 5.0 A, RθJA = 50 °C/W | Larger footprint (4.5 × 2.7 mm), higher clamping voltage, no AEC-Q101 qualification | Select for cost-sensitive industrial designs where board space and automotive qualification are not required |
| SMF15A | SOD-123FL package, 15 V VBR, 23.2 V VC @ 5.0 A, 1.1 mm height, no side-wettable flanks | No AOI support, lower thermal performance (RθJM not specified), non-AEC-Q101 | Choose when legacy SMT process lacks AOI capability and thermal demands are moderate (TJ ≤ 150 °C) |
Compared with SMAJ15A-E3/57T and SMF15A, T6N15AHM3/H offers superior thermal management (RθJM = 5 °C/W), guaranteed AEC-Q101 compliance, and manufacturability assurance via side-wettable flanks-critical for zero-defect automotive production.

FAQ
What is the exact breakdown voltage tolerance for T6N15AHM3/H?
The T6N15AHM3/H has a breakdown voltage (VBR) range of 14.3 V (min) to 15.8 V (max) at 1.0 mA test current, corresponding to ±5 % tolerance around the nominal 15.0 V value as specified in the Vishay datasheet document 98432. This tight tolerance ensures consistent clamping behavior across production lots and temperature ranges.
Is T6N15AHM3/H qualified for automotive use under AEC-Q101?
Yes, T6N15AHM3/H is explicitly AEC-Q101 qualified, as confirmed by the HM3 suffix in its ordering code and documented in the Vishay datasheet revision 10-Nov-2023. It has passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST) per AEC-Q101 standards.
Does T6N15AHM3/H require special PCB layout considerations?
Yes - the exposed anode pad of T6N15AHM3/H must be connected to a minimum 40 mm² copper pour on the PCB to achieve the specified RθJM = 5 °C/W and sustain 600 W peak pulse power. Insufficient copper area will cause thermal saturation and premature failure during repetitive surge events.
What is the maximum clamping voltage of T6N15AHM3/H at rated surge current?
The maximum clamping voltage (VC) of T6N15AHM3/H is 21.2 V at 5.0 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet and ensures protected ICs remain within safe operating voltage margins during standardized automotive surge events.
Can T6N15AHM3/H replace older SMAJ15A in existing designs?
T6N15AHM3/H is not a drop-in replacement for SMAJ15A due to different package (DFN3820A vs. DO-214AC), thermal interface requirements, and pinout. While both offer 15 V VBR, redesign is required to accommodate the side-wettable DFN footprint, exposed anode pad, and tighter thermal layout rules for T6N15AHM3/H.
