Product details
Overview
T6N13AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 13.0 V nominal breakdown voltage (VBR), 11.1 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 in engine control units and ADAS modules.
For engineers reviewing the T6N13AHM3/H datasheet, T6N13AHM3/H pinout, T6N13AHM3/H application, or T6N13AHM3/H equivalent, key selection criteria include clamping voltage (18.2 V at IPPM), junction temperature rating up to +185 °C, unidirectional polarity, low-profile DFN3820A footprint with side-wettable flanks, and compatibility with automated optical inspection (AOI) and high-reliability automotive PCB assembly.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and robust transient suppression. Its unidirectional configuration enables precise clamping on positive-going transients while maintaining low leakage (<2.0 μA at VWM) across operating temperatures.
The DFN3820A package delivers thermal resistance of RθJM = 5 °C/W (typ.) to the PCB mount, supporting sustained operation under automotive thermal cycling. It meets IEC 61000-4-2 ±30 kV contact/air ESD immunity and MSL Level 1 reflow compatibility (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 13.0 V - Ensures reliable triggering above system operating voltage (e.g., 12 V automotive rails) without false conduction. |
| VWM | 11.1 V - Maximum continuous reverse voltage before leakage exceeds 2.0 μA; compatible with 12 V nominal systems. |
| VC @ IPPM | 18.2 V - Clamping voltage limits downstream IC stress during 33.0 A surge (10/1000 μs), critical for MOSFET gate protection. |
| PPPM | 600 W - Sustains high-energy transients common in automotive load-dump and inductive kick scenarios. |
| TJ max | +185 °C - Enables deployment in under-hood ECUs and powertrain modules where ambient temperatures exceed 125 °C. |
| ESD Rating | ±30 kV (IEC 61000-4-2) - Provides robust electrostatic discharge immunity for sensor interface circuits. |
| Package | DFN3820A - 3.95 mm × 2.18 mm × 0.88 mm low-profile leadless package with side-wettable flanks for AOI-compatible solder joint inspection. |
Pinout & Package
DFN3820A package: 2-terminal, single unidirectional TVS configuration. Cathode marked by color band; anode connected to exposed thermal pad (heatsink). Dimensions: 3.95 mm × 2.18 mm × 0.88 mm (L × W × H); side-wettable flanks support automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pad) | Common cathode return path / thermal interface | Exposed copper pad serves as primary heat sink and electrical connection to ground plane; requires full-solder coverage for thermal and current handling. |
| Cathode (Top-side terminal) | Transient voltage clamp output | Connected to protected line (e.g., sensor signal or MOSFET gate); conducts surge current to anode when VIN > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile DFN3820A | 0.88 mm height enables use in space-constrained automotive modules where Z-height is limited by connector or housing clearance. |
| AEC-Q101 qualification | Validated for automotive applications including engine management, transmission control, and ADAS sensor interfaces per stress test requirements. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder fillet integrity without X-ray, reducing post-reflow defect escape in high-volume production. |
| Junction passivation | Optimized anisotropic rectifier design ensures stable VBR drift <0.072 %/°C and low leakage over lifetime under thermal cycling. |
| Halogen-free & RoHS | HM3 suffix confirms compliance with automotive environmental standards and end-of-life material restrictions (per Vishay doc. 99912). |
Applications
| Engine Control Unit (ECU) Power Input Protection | ADAS Camera Sensor Signal Line Protection |

Use Scenario: Guards high-side/low-side MOSFET gates in EPS motor drivers against inductive kickback during PWM switching. IC Role / Device Role: TVS placed between gate driver output and MOSFET gate, referenced to source. Use Value: Fast response and 18.2 V clamping limit gate oxide stress below 20 V, extending MOSFET lifetime under repeated transient exposure. | Use Scenario: Protects LIN bus transceiver pins from battery disconnect spikes and ESD in door module and lighting control nodes. IC Role / Device Role: Unidirectional TVS on LIN data line (dominant/recessive side), grounded via low-inductance path. Use Value: 11.1 V VWM ensures no interference with LIN's 12 V nominal signaling; 18.2 V clamping prevents transceiver latch-up during 24 V battery transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-HF | DO-214AC (SMA) package; higher RθJA (190 °C/W); VC = 21.5 V at same IPPM | Less suitable for high-density automotive PCBs due to larger footprint and no side-wettable flanks. | Prefer T6N13AHM3/H for space-constrained, AOI-driven automotive designs requiring lower clamping and better thermal coupling. |
| SMF13A | SOD-123FL package; VBR = 13.3–14.7 V; PPPM = 200 W; not AEC-Q101 qualified. | Limited to consumer or industrial applications; insufficient for automotive under-hood thermal or reliability requirements. | Select T6N13AHM3/H when AEC-Q101 qualification, +185 °C operation, or 600 W surge capability is mandatory. |
Compared with SMAJ13A-HF and SMF13A, the T6N13AHM3/H provides superior thermal performance (RθJM = 5 °C/W), tighter VBR tolerance (±5 %), and automotive-grade process validation-enabling smaller PCB area, higher reliability in thermal cycling, and guaranteed conformance to vehicle OEM stress-test protocols.

FAQ
What is the breakdown voltage tolerance for T6N13AHM3/H?
The T6N13AHM3/H has a breakdown voltage tolerance of ±5 %, with a nominal VBR of 13.0 V (min 12.4 V, max 13.7 V at 1.0 mA test current). This tight tolerance ensures predictable clamping behavior in automotive 12 V systems where overvoltage margin must be precisely controlled to protect sensitive downstream ICs without premature conduction.
Is T6N13AHM3/H suitable for under-hood automotive applications?
Yes, the T6N13AHM3/H is explicitly qualified to AEC-Q101 and rated for junction temperatures up to +185 °C, making it suitable for under-hood applications such as engine control units and transmission control modules. Its DFN3820A package provides low thermal resistance (RθJM = 5 °C/W typ.), and its passivated anisotropic rectifier structure ensures stable performance across extended thermal cycling profiles defined in automotive qualification standards.
Does T6N13AHM3/H support automated optical inspection (AOI)?
Yes, the T6N13AHM3/H uses a DFN3820A package with side-wettable flanks, enabling reliable solder joint inspection using standard AOI systems without requiring X-ray. This feature is confirmed in the Vishay datasheet (doc. 98432, revision 10-Nov-2023) and supports high-yield, zero-defect manufacturing for automotive electronics production lines.
What is the maximum clamping voltage of T6N13AHM3/H at rated surge current?
The maximum clamping voltage (VC) of T6N13AHM3/H is 18.2 V at its rated peak pulse current (IPPM) of 33.0 A under a 10/1000 μs waveform. This value is measured per Figure 1 in the official Vishay datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case surge events, directly impacting MOSFET gate oxide safety and IC input stage survivability.
How does the HM3 suffix affect the T6N13AHM3/H specification?
The HM3 suffix on T6N13AHM3/H indicates halogen-free, RoHS-compliant construction with matte tin-plated terminals that meet JESD 201 Class 2 whisker resistance and J-STD-002/JESD 22-B102 solderability requirements. It also confirms AEC-Q101 qualification-distinguishing it from non-HM3 variants and ensuring compliance with automotive environmental and reliability mandates.
