Overview
TA6L36AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SlimSMAW (DO-221AD) package, designed for clamping inductive switching transients and ESD events on automotive sensor signal lines. It features 36 V breakdown voltage (VBR = 34.2–37.8 V at IT = 1.0 mA), 30.8 V stand-off voltage (VWM), 49.9 V maximum clamping voltage (VC) at 12.0 A peak pulse current, and 600 W peak pulse power (10/1000 µs).
For engineers reviewing the TA6L36AHM3/H datasheet, TA6L36AHM3/H pinout, TA6L36AHM3/H application, or TA6L36AHM3/H equivalent, this device is selected for high-reliability automotive electronics requiring AEC-Q101 qualification, 185 °C junction temperature capability, and halogen-free, RoHS-compliant construction in a low-profile SMD package.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance across -65 °C to +185 °C operating junction temperature. Its unidirectional configuration enables precise reverse-biased protection of DC-powered signal paths without forward conduction interference.
The device is optimized for fast transient suppression with 10/1000 µs waveform compliance, 0.090 %/°C temperature coefficient of VBR, and thermal resistance RθJA ≤ 150 °C/W on FR4 PCB - enabling robust surge handling in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 34.2–37.8 V at 1.0 mA test current - defines minimum clamping onset threshold under transient stress |
| Stand-off Voltage VWM | 30.8 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA, ensuring no false triggering |
| Clamping Voltage VC | 49.9 V at 12.0 A IPPM - limits downstream IC voltage during 600 W surge, protecting 3.3 V/5 V logic interfaces |
| Peak Pulse Power | 600 W (10/1000 µs) - sustains high-energy transients common in automotive load-dump and inductive kick scenarios |
| Junction Temperature Range | -65 °C to +185 °C - supports operation in engine bay, transmission control, and ADAS modules without derating |
| Package | SlimSMAW (DO-221AD) - 2.30 × 4.00 × 1.10 mm footprint with cathode band marking and matte tin-plated leads |
| AEC-Q101 Qualified | HM3 suffix confirms qualification per JESD22-A108 and JESD22-A114, including class 2 whisker testing per JESD201 |
Pinout & Package
SlimSMAW (DO-221AD) is a two-terminal surface-mount package with cathode marked by a color band on the top surface. Anode and cathode terminals are located on opposite ends of the molded body; polarity must be observed during PCB layout to ensure correct reverse-bias protection orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; forms current sink during clamping event |
| Cathode | High-side connection point | Connected to protected line (e.g., sensor output); reverse-biased during normal operation, conducts only during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 185 °C Junction Capability | Enables placement in high-temperature zones (e.g., near power stages or under-hood ECUs) without thermal derating penalties |
| MSL Level 1 Moisture Sensitivity | Allows unlimited floor life and reflow up to 260 °C peak, eliminating bake requirements before assembly |
| Halogen-Free & RoHS-Compliant | Meets automotive environmental standards (e.g., ELV, IMDS) and supports sustainable manufacturing compliance |
| Optimized Junction Passivation | Reduces parametric drift and leakage growth under high-temperature bias stress, improving long-term reliability |
| Low Profile (1.10 mm height) | Minimizes board space and profile in compact ADAS camera modules and radar front-ends where Z-height is constrained |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A-H | Same VBR range (34.2–37.8 V), but SMB (DO-214AA) package (4.57 × 3.94 × 2.29 mm) - 110 % larger footprint and 105 % taller than SlimSMAW | Higher thermal resistance (RθJA ≈ 180 °C/W) limits power handling in dense layouts; not AEC-Q101 qualified in standard grade | Select when legacy SMB footprint is fixed and AEC-Q101 is not required; avoid in new automotive designs targeting ASIL-B/C. |
| TPSMF36A | Identical SlimSMAW package and AEC-Q101 qualification, but higher VC = 58.1 V at same IPPM - 16 % less clamping margin than TA6L36AHM3/H | Lower clamping performance increases risk of downstream IC overvoltage during worst-case transients; requires tighter system-level margin analysis | Acceptable for non-safety-critical body electronics where 58.1 V clamping is within IC absolute max ratings; not recommended for ADAS or powertrain. |
Compared with SMBJ36A-H and TPSMF36A, TA6L36AHM3/H delivers superior thermal performance (RθJA ≤ 150 °C/W), tighter clamping (49.9 V), and guaranteed AEC-Q101 qualification in the smallest automotive-grade SMD TVS footprint - making it optimal for next-generation compact, high-temperature automotive modules.

FAQ
What is the meaning of the 'HM3' suffix in TA6L36AHM3/H?
The HM3 suffix in TA6L36AHM3/H indicates halogen-free, RoHS-compliant construction and full AEC-Q101 qualification, including JESD201 Class 2 whisker testing. This suffix confirms that the TA6L36AHM3/H meets stringent automotive reliability requirements for use in safety-critical and high-temperature environments such as engine control and ADAS systems.
Does TA6L36AHM3/H support bidirectional transient suppression?
No, TA6L36AHM3/H is a unidirectional TVS diode and provides protection only against reverse-polarity transients and ESD events on positively referenced signal lines. It must be installed with cathode toward the protected line and anode to ground. For bidirectional protection, a separate symmetric device or dual-diode configuration is required - TA6L36AHM3/H does not provide symmetrical clamping.
What is the maximum clamping voltage of TA6L36AHM3/H at its rated peak pulse current?
The maximum clamping voltage of TA6L36AHM3/H is 49.9 V at 12.0 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value ensures that downstream components with 5 V or 3.3 V absolute maximum ratings remain protected during surge events, provided proper PCB layout and grounding practices are followed for the TA6L36AHM3/H installation.
Is TA6L36AHM3/H compatible with lead-free reflow soldering processes?
Yes, TA6L36AHM3/H is fully compatible with lead-free reflow soldering, meeting MSL Level 1 per J-STD-020 and supporting a maximum peak reflow temperature of 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102, ensuring reliable wetting and intermetallic formation without voiding or dewetting during standard Pb-free assembly of the TA6L36AHM3/H.
How does the temperature coefficient of VBR affect TA6L36AHM3/H performance at elevated temperatures?
The TA6L36AHM3/H has a typical VBR temperature coefficient of +0.090 %/°C, meaning its breakdown voltage increases linearly with junction temperature. At 150 °C, VBR rises ~11.25 % above its 25 °C value - from 36.0 V to ~40.1 V - which delays clamping onset but maintains safe standoff margin. System designers must verify that this shift remains within the protected circuit's overvoltage tolerance window for the TA6L36AHM3/H to function correctly.
