Product details
Overview
TA6L36AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in SlimSMAW (DO-221AD) package, with 36.0 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 12.0 A peak pulse current (IPPM), and 49.9 V clamping voltage (VC) - designed for automotive sensor line protection against inductive switching transients.
For engineers reviewing the TA6L36AHM3/I datasheet, TA6L36AHM3/I pinout, TA6L36AHM3/I application, or TA6L36AHM3/I equivalent, this page delivers verified electrical parameters, thermal performance at TJ = 185 °C, AEC-Q101 qualification status, SlimSMAW mechanical dimensions, and real-world use cases in automotive electronics.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable junction behavior up to 185 °C, enabling operation in high-reliability automotive environments. Its unidirectional configuration provides low-leakage reverse blocking (1.0 µA at VWM) and precise clamping response under 10/1000 µs surge conditions.
The device complies with MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and features matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102. Polarity is marked by a cathode band on the SlimSMAW case outline.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V - ensures reliable triggering above system operating voltage while accommodating ±5% tolerance and temperature drift |
| VWM | 30.8 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA, matching 3.3 V or 5 V rail protection with margin |
| VC @ IPPM | 49.9 V - clamping voltage during 12.0 A transient, limiting downstream IC stress to safe levels per ISO 7637-2 |
| PPPM | 600 W (10/1000 µs) - handles typical automotive load-dump and inductive-switching energy without degradation |
| TJ max | 185 °C - enables placement near hot components (e.g., powertrain ECUs) without derating loss |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and whisker resistance (JESD 201 Class 2) |
Pinout & Package

Applications
| Automotive Sensor Protection | Power Line Transient Suppression |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from ESD and load-dump events in ADAS ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp fast-rising transients before they reach sensitive input stages. Use Value: Limits clamping voltage to 49.9 V at 12.0 A, preserving signal integrity and preventing latch-up in 3.3 V/5 V interface ICs per ISO 10605. | Use Scenario: Safeguarding 12 V power rails feeding microcontrollers and communication ICs in body control modules. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 3a/b (switching noise) energy. Use Value: Withstands 600 W peak pulse power and maintains <1.0 µA leakage at 30.8 V, ensuring no standby current penalty or false resets. |
| Engine Control Unit (ECU) Input Protection | Electric Power Steering (EPS) Module Protection |
Use Scenario: Shielding throttle position sensor (TPS) and crankshaft position sensor (CKP) signal lines from ignition coil coupling and alternator ripple. IC Role / Device Role / Timing Role: Fast-response unidirectional suppressor placed at connector entry point to divert transients before reaching MCU ADC inputs. Use Value: Breakdown at 36.0 V ensures immunity to normal 12 V system fluctuations while triggering within nanoseconds of overvoltage onset. | Use Scenario: Guarding motor driver feedback lines and Hall-effect sensor interfaces in EPS systems exposed to high-current switching noise. IC Role / Device Role / Timing Role: TVS integrated into compact motor control board layout adjacent to gate drivers and current sense amplifiers. Use Value: SlimSMAW package (0.90 mm height) fits tight spacing constraints; 185 °C TJ rating matches EPS thermal environment near brushless motor windings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Same VBR (36.0 V), but SMB package (DO-214AA); RθJA = 150 °C/W vs. 120–150 °C/W for TA6L36AHM3/I; no AEC-Q101 qualification | General industrial use only; not validated for automotive temperature cycling or whisker resistance | Select when AEC-Q101 is not required and board space permits larger SMB footprint |
| SMCJ36A | Higher PPPM (1500 W), same VBR, but SMC package (DO-214AB); 2.5 mm height vs. 0.9 mm for SlimSMAW; TJ max = 175 °C | Used where higher surge energy must be absorbed, but incompatible with ultra-low-profile layouts | Choose for heavy-duty industrial loads if height and thermal resistance allow |
Compared with SMBJ36A and SMCJ36A, TA6L36AHM3/I delivers automotive-grade reliability in the lowest profile package, with verified 185 °C operation and AEC-Q101 compliance - critical for next-generation compact, high-temperature automotive modules.

The TA6L36AHM3/I has a guaranteed breakdown voltage (VBR) range of 34.2 V (min) to 37.8 V (max) at 1.0 mA test current, with a nominal value of 36.0 V. This specification is measured at TA = 25 °C and remains stable across temperature due to its 0.090 %/°C temperature coefficient - critical for consistent clamping in automotive ambient ranges.
Is TA6L36AHM3/I qualified for automotive applications?
Yes, TA6L36AHM3/I is AEC-Q101 qualified and meets JESD 201 Class 2 whisker test requirements. Its SlimSMAW package, 185 °C maximum junction temperature, and passivated anisotropic rectifier technology make it suitable for under-hood and powertrain applications per automotive reliability standards.
What package type does TA6L36AHM3/I use, and what are its key mechanical features?
TA6L36AHM3/I uses the SlimSMAW (DO-221AD) package: a low-profile surface-mount case with maximum height of 0.90 mm, cathode band marking, matte tin-plated leads, and UL 94 V-0 molding compound. It is compatible with SOD-128 footprints and supports 260 °C lead-free reflow per J-STD-020 MSL Level 1.
How does TA6L36AHM3/I perform under high-temperature operating conditions?
TA6L36AHM3/I is rated for continuous operation up to TJ = 185 °C, with derated pulse power per Figure 2 of the datasheet. Its junction passivation and thermal resistance (RθJM = 12–15 °C/W) ensure stable VBR and leakage performance in engine bay or EPS module environments where ambient temperatures exceed 125 °C.
What is the clamping voltage of TA6L36AHM3/I at its rated peak pulse current?
At its rated peak pulse current (IPPM) of 12.0 A (10/1000 µs waveform), TA6L36AHM3/I clamps to a maximum voltage of 49.9 V. This value is guaranteed per the datasheet and defines the upper voltage limit imposed on protected circuitry during transient events - essential for safeguarding 3.3 V or 5 V logic interfaces.
