Product details
Overview
TA6L15AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in SlimSMAW (DO-221AD) package, designed for automotive-grade overvoltage protection. It features 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 28.3 V maximum clamping voltage at 21.2 A peak pulse current, 600 W peak pulse power (10/1000 µs), and AEC-Q101 qualification with TJ = 185 °C capability.
For engineers reviewing the TA6L15AHM3/H datasheet, TA6L15AHM3/H pinout, TA6L15AHM3/H application, or TA6L15AHM3/H equivalent, this device serves as a high-reliability TVS for protecting automotive sensor signal lines, MOSFET gate drivers, and microcontroller I/O against inductive switching transients and load dump events under high-temperature operating conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance across -65 °C to +185 °C junction temperature range. Its unidirectional configuration enables precise reverse-biased surge suppression without forward conduction during normal operation.
The SlimSMAW (DO-221AD) package provides low thermal resistance (RθJM ≤ 15 °C/W) and meets MSL Level 1 with 260 °C lead-free reflow compatibility. The device's 0.076 %/°C temperature coefficient of VBR ensures predictable voltage drift under thermal stress.
Key Specifications

Pinout & Package
SlimSMAW (DO-221AD) is a two-terminal surface-mount package with cathode indicated by a color band. Anode and cathode terminals are located on opposite ends of the molded body; polarity must be observed during PCB layout to ensure correct unidirectional clamping behavior.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during clamping | Connected to protected line (e.g., sensor output); conducts surge current toward ground when VAK exceeds VBR |
| Cathode | Current exit terminal during clamping | Connected to system ground; forms low-impedance path to shunt transient energy away from downstream ICs |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier structure ensures stable VBR and low leakage over lifetime and temperature |
| High-temperature operation | TJ = 185 °C rating supports placement near heat sources in engine control units and ADAS modules |
| Low-profile packaging | SlimSMAW footprint saves board space vs. SMA/SMB while maintaining robust thermal performance |
| AEC-Q101 qualification | Validated for automotive applications including humidity, vibration, and thermal shock per JEDEC standards |
| Halogen-free & RoHS | HM3 suffix denotes compliance with environmental regulations and material categorization per Vishay Doc. 99912 |
Applications
| Automotive Sensor Protection | Power MOSFET Gate Protection |
|---|---|
|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors exposed to load-dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and MCU ADC input to clamp transients before they reach sensitive front-end circuitry. Use Value: Clamps 12.8 V working voltage transients to ≤28.3 V within nanoseconds, preserving signal integrity and preventing ADC saturation or latch-up. |
Use Scenario: Safeguarding N-channel MOSFET gate-source terminals against voltage spikes caused by inductive flyback in motor driver circuits. IC Role / Device Role / Timing Role: Connected directly across gate and source to limit VGS excursion during fast-switching transitions and fault conditions. Use Value: Limits gate overvoltage to 28.3 V at 21.2 A surge, preventing oxide breakdown and ensuring long-term gate reliability in 12 V/24 V automotive systems. |
| Microcontroller I/O Protection | Infotainment System Data Lines |
|
Use Scenario: Shielding UART, CAN, or LIN interface pins on automotive microcontrollers from ESD and coupled transients on harness-connected peripherals. IC Role / Device Role / Timing Role: Placed at connector interface to absorb fast-rising ESD (IEC 61000-4-2) and slower inductive surges before reaching MCU GPIO. Use Value: Provides 600 W pulse power handling and <1 μA leakage at 12.8 V, enabling robust protection without compromising low-power sleep mode current budgets. |
Use Scenario: Protecting LVDS or FPD-Link video data lines in head-unit displays and camera modules from cable-induced transients and hot-swap events. IC Role / Device Role / Timing Role: Installed adjacent to connector to suppress common-mode and differential-mode surges on high-speed serial links. Use Value: Maintains low capacitance (<100 pF typical at VWM) and tight VBR tolerance (±2.3%) to avoid signal distortion or jitter on multi-Mbps video streams. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-H | Same VWM (12.8 V) and VC (24.4 V @ 24.4 A), but lower PPPM (400 W) and non-AEC-Q101 rated | Limited to industrial/commercial grade; not qualified for automotive under-hood use | Select when cost sensitivity outweighs automotive qualification requirements and surge energy is ≤400 W |
| TPSMD15A | Higher VC (30.5 V @ 19.7 A), same PPPM (600 W), AEC-Q101 qualified, but larger SMA package (DO-214AC) | Requires more PCB area; higher thermal resistance (RθJA ≈ 160 °C/W vs. 150 °C/W) | Choose when legacy SMA footprint compatibility is required and SlimSMAW board space constraints do not apply |
Compared with SMAJ15A-H and TPSMD15A, TA6L15AHM3/H delivers superior thermal performance in a smaller footprint, tighter VBR tolerance (±2.3% vs. ±5%), and guaranteed AEC-Q101 compliance-making it optimal for space-constrained, high-reliability automotive signal-line protection.

Does TA6L15AHM3/H meet AEC-Q101 requirements for automotive use?
Yes, TA6L15AHM3/H carries the HM3 suffix, confirming full AEC-Q101 qualification. It passes stress tests including temperature cycling, high-temperature operating life, and JESD201 Class 2 whisker testing-making it approved for under-hood and safety-critical automotive applications.
What is the maximum clamping voltage of TA6L15AHM3/H at its rated peak pulse current?
The TA6L15AHM3/H exhibits a maximum clamping voltage (VC) of 28.3 V at its rated peak pulse current (IPPM) of 21.2 A under the standard 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does the thermal resistance of TA6L15AHM3/H compare to standard SMA packages?
TA6L15AHM3/H in SlimSMAW (DO-221AD) achieves RθJM ≤ 15 °C/W and RθJA ≤ 150 °C/W on FR4, outperforming traditional SMA (DO-214AC) packages (RθJA ≈ 160–180 °C/W). This lower thermal resistance enables higher sustained power dissipation and improved reliability in thermally dense automotive PCB layouts.
