Product details
Overview
TA6L8.2AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) in the PAR® series, designed for clamping inductive load-switching transients and ESD events on automotive sensor signal lines and MOSFET gates. It features a breakdown voltage of 7.79–8.61 V at 10 mA, 600 W peak pulse power (10/1000 μs), 12.1 V clamping voltage at rated surge current, and operates up to +185 °C junction temperature.
For engineers reviewing the TA6L8.2AHM3/I datasheet, TA6L8.2AHM3/I pinout, TA6L8.2AHM3/I application, or TA6L8.2AHM3/I equivalent, key selection criteria include unidirectional polarity, SlimSMAW (DO-221AD) package compatibility, AEC-Q101 qualification, TJ = 185 °C capability, and low-leakage performance (≤100 μA at 7.02 V, ≤200 μA at 150 °C).
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature stability and automotive reliability. Its unidirectional configuration provides precise reverse-biased clamping with tight VBR tolerance (±5% typical) and low dynamic impedance, enabling fast response to sub-microsecond transients.
The device is rated for 600 W peak pulse power under standardized 10/1000 μs waveform conditions and exhibits a positive temperature coefficient of breakdown voltage (+0.056 %/°C), supporting predictable voltage shift across its -65 °C to +185 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.79 / 8.20 / 8.61 V at 10 mA - defines precise clamping onset threshold for overvoltage protection |
| VWM | 7.02 V - maximum continuous reverse working voltage before leakage exceeds 100 μA |
| VC @ IPPM | 12.1 V - clamped voltage during 600 W surge, limiting stress on downstream ICs |
| PPPM | 600 W (10/1000 μs) - robust energy absorption for automotive load-dump and ISO 7637-2 pulses |
| TJ max | +185 °C - enables placement near hot components (e.g., powertrain ECUs) without derating |
| Leakage @ VWM, 150 °C | ≤200 μA - ensures minimal signal distortion in high-temp sensor interfaces |
| Package | SlimSMAW (DO-221AD) - low-profile, MSL Level 1, 260 °C reflow compatible |
Pinout & Package
SlimSMAW (DO-221AD) is a surface-mount, low-profile, two-terminal package with cathode indicated by a color band. The device has no internal connections beyond anode and cathode terminals.

Applications
| Automotive Sensor Protection | Power MOSFET Gate Clamp |
|---|---|
Use Scenario: Protecting analog outputs of pressure, temperature, and position sensors in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and ground to clamp transients before they reach ADC input or signal conditioner. Use Value: Prevents latch-up or damage to precision op-amps and SAR ADCs by limiting voltage to ≤12.1 V during 600 W surges. | Use Scenario: Suppressing Miller-induced voltage spikes on N-channel MOSFET gates during high-speed switching in 12 V automotive DC-DC converters. IC Role / Device Role / Timing Role: Fast-clamping diode connected between gate and source to absorb dv/dt-induced coupling energy. Use Value: Maintains gate integrity below 12.1 V clamping level, preventing unintended turn-on and reducing switching losses. |
| CAN Bus Line Protection | LIN Bus Transceiver Interface |
Use Scenario: Safeguarding CAN_H/CAN_L differential pair against ESD and coupled transients in body control modules and gateway ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS on each bus line referenced to ground, leveraging low capacitance (<50 pF) and fast response. Use Value: Preserves signal integrity at 1 Mbps while meeting ISO 10605 ESD immunity (±25 kV air, ±20 kV contact). | Use Scenario: Shielding LIN transceiver pins from battery disconnect transients and electrostatic discharge in door modules and seat controllers. IC Role / Device Role / Timing Role: Low-leakage (≤100 μA at 7.02 V) TVS placed on LIN bus line to avoid loading the 19.2 kbps signal. Use Value: Ensures reliable wake-up functionality and prevents false triggering due to sub-μA-level leakage drift at elevated temperatures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | VBR = 8.5–9.4 V (wider tolerance), VC = 12.5 V, same 600 W rating, SMA package (larger footprint) | Higher clamping voltage and less precise VBR reduce margin for low-voltage ICs; SMA thermal resistance higher than SlimSMAW | Select SMAJ8.0A only if board layout allows larger package and system tolerates 0.4 V higher clamping. |
| TPSMF8.0A | VBR = 8.5–9.4 V, VC = 12.5 V, same SlimSMAW package, but not AEC-Q101 qualified (only industrial grade) | Lacks automotive qualification testing (HTRB, TC, ESD); unsuitable for safety-critical or OEM-specified designs | Use TPSMF8.0A only in non-automotive industrial applications where AEC-Q101 is not mandated. |
Compared with SMAJ8.0A and TPSMF8.0A, TA6L8.2AHM3/I delivers tighter VBR (±5%), lower VC (12.1 V), and full AEC-Q101 qualification in the space-optimized SlimSMAW package-making it preferred for automotive signal-line protection where voltage margin and reliability are critical.

FAQ
What is the breakdown voltage tolerance of TA6L8.2AHM3/I?
The TA6L8.2AHM3/I has a specified breakdown voltage range of 7.79 V (min) to 8.61 V (max) at 10 mA test current, corresponding to ±5% tolerance around the nominal 8.2 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports precise overvoltage margining in automotive signal chains where TA6L8.2AHM3/I is deployed.
Is TA6L8.2AHM3/I qualified for automotive use?
Yes, TA6L8.2AHM3/I carries the HM3 suffix, indicating full AEC-Q101 qualification per JESD22-A108 (HTOL), JESD22-A114 (HTRB), and JESD201 Class 2 whisker testing. It is approved for use in automotive powertrain, chassis, and body electronics where TA6L8.2AHM3/I must withstand extended thermal cycling, high humidity, and mechanical vibration without degradation.
What is the maximum clamping voltage of TA6L8.2AHM3/I under surge conditions?
The maximum clamping voltage (VC) of TA6L8.2AHM3/I is 12.1 V when subjected to its rated peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuits during worst-case transients, making TA6L8.2AHM3/I suitable for safeguarding 5 V and 3.3 V logic interfaces.
Does TA6L8.2AHM3/I have a bidirectional configuration option?
No, TA6L8.2AHM3/I is strictly unidirectional. The "A" suffix in the part number denotes unidirectional polarity, and the datasheet confirms "Unidirectional only" as a primary characteristic. Bidirectional variants (e.g., TA6L8.2CA) are separate part numbers and are not functionally interchangeable with TA6L8.2AHM3/I without circuit redesign.
What package type does TA6L8.2AHM3/I use, and is it compatible with automated SMT assembly?
TA6L8.2AHM3/I uses the SlimSMAW (DO-221AD) package - a low-profile, surface-mount case with MSL Level 1 rating and compatibility with 260 °C peak reflow profiles. Its matte tin-plated leads meet J-STD-002 and JESD22-B102 solderability standards, ensuring reliable automated placement and reflow in high-volume automotive PCB assembly where TA6L8.2AHM3/I is commonly used.
