Product details
Overview
TA6L11AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SlimSMAW (DO-221AD) package, with 11.0 V nominal breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), and 600 W peak pulse power rating (10/1000 µs). It delivers 38.5 V clamping voltage at 5.0 A peak pulse current and operates up to +185 °C junction temperature-designed for automotive sensor signal-line protection against inductive switching transients.
For engineers reviewing the TA6L11AHM3/I datasheet, TA6L11AHM3/I pinout, TA6L11AHM3/I application, or TA6L11AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, TJ = 185 °C capability, unidirectional configuration, SlimSMAW mechanical compatibility, and verified clamping performance under ISO 7637-2 pulse 1/2a/5a conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature stability and low-leakage operation. Its unidirectional structure provides precise reverse-biased clamping with 2.0 µA max reverse leakage at VWM and 5.0 µA at 150 °C, enabling robust protection of sensitive IC inputs without compromising signal integrity.
The device complies with JEDEC standards for thermal resistance (RθJA ≤ 150 °C/W, RθJM ≤ 15 °C/W) and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow tolerance. Its cathode-band polarity marking and matte tin-plated terminals ensure reliable solderability per J-STD-002 and JESD22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 10.5 / 11.0 / 11.6 V - ensures reliable triggering above system operating voltage while avoiding false trips during normal transients |
| VWM | 9.40 V - maximum continuous reverse voltage before significant leakage, compatible with 9 V nominal automotive supply rails |
| IPPM | 5.0 A (10/1000 µs) - supports surge immunity per ISO 7637-2 Pulse 1 (inductive load dump) in automotive ECUs |
| VC @ IPPM | 38.5 V - clamping level low enough to protect 3.3 V/5 V logic interfaces behind series impedance |
| TJ max | +185 °C - enables placement near hot components (e.g., power MOSFETs, engine control modules) without derating |
| Package | SlimSMAW (DO-221AD) - 3.6 × 2.3 mm footprint with 1.1 mm height, optimized for space-constrained automotive PCB layouts |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and whisker testing (JESD201 Class 2) |
Pinout & Package
SlimSMAW (DO-221AD) is a low-profile, surface-mount package with two terminals: anode and cathode. The cathode is marked by a color band on the body end. Leads are matte tin-plated for compatibility with lead-free reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to protected line ground or low-side reference | Provides low-impedance path to ground during overvoltage events when cathode is held at higher potential |
| Cathode | Current exit point in forward bias; connected to protected signal or power line | Acts as the "protected node" input-clamps voltage to ≤38.5 V when transient exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature junction capability | TJ = 185 °C enables direct mounting on engine control boards without thermal derating penalties |
| AEC-Q101 qualification + JESD201 Class 2 whisker test | Validated for automotive under-hood applications requiring long-term metallurgical stability |
| Low-profile SlimSMAW package | 1.1 mm max height allows use in ultra-thin modules such as ADAS camera housings and radar sensors |
| Optimized junction passivation | Reduces leakage drift over time and temperature-critical for battery-powered sensor nodes with multi-year field life |
| 600 W peak pulse power (10/1000 µs) | Handles worst-case ISO 7637-2 Pulse 5a (load dump) surges without degradation in automotive 12 V systems |
Applications
| Automotive Sensor Signal Protection | Engine Control Unit (ECU) Power Input |

IC Role / Device Role / Timing Role: Localized TVS on isolated gate driver supply and logic inputs. Use Value: Withstands repeated 10/1000 µs surges up to 5.0 A without parameter shift-ensures functional safety in ASIL-B systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Same VBR range (10.5–11.6 V), but rated for 400 W PPPM and not AEC-Q101 qualified | Limited to industrial/commercial environments; lacks automotive reliability validation and high-temperature derating data | Select SMAJ11A only for cost-sensitive non-automotive designs where 185 °C operation and whisker resistance are not required |
| TPSMA6L11A | Identical electrical specs and AEC-Q101 qualification, but packaged in standard SMA (DO-214AC) with larger 4.5 mm height | Compatible functionally but requires PCB layout change due to 1.4 mm taller profile and different pad geometry | Choose TPSMA6L11A only if existing design uses SMA footprints and SlimSMAW rework is impractical |
Compared with SMAJ11A and TPSMA6L11A, the TA6L11AHM3/I uniquely combines AEC-Q101 qualification, 185 °C junction rating, and SlimSMAW packaging-making it the only option that satisfies space, reliability, and automotive environmental requirements simultaneously without layout compromise.

FAQ
What is the clamping voltage of the TA6L11AHM3/I at its rated peak pulse current?
The TA6L11AHM3/I has a maximum clamping voltage (VC) of 38.5 V at 5.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's datasheet revision 17-Sep-2021, page 2. The TA6L11AHM3/I maintains this clamping performance across its full operating temperature range up to +185 °C junction temperature.
Is the TA6L11AHM3/I qualified for automotive applications?
Yes, the TA6L11AHM3/I is AEC-Q101 qualified and meets JESD201 Class 2 whisker test requirements. Its HM3 suffix denotes halogen-free, RoHS-compliant construction and full automotive qualification. The TA6L11AHM3/I is designed for under-hood and chassis-mounted applications where high-temperature stability and long-term reliability are mandatory.
What package does the TA6L11AHM3/I use, and how does it differ from standard SMA?
The TA6L11AHM3/I uses the SlimSMAW (DO-221AD) package: 3.6 mm × 2.3 mm × 1.1 mm, significantly lower than standard SMA (DO-214AC) at 4.5 mm height. This enables tighter board stacking and improved thermal performance in confined spaces. The TA6L11AHM3/I's SlimSMAW footprint is incompatible with SMA land patterns and requires dedicated PCB layout.
What is the maximum reverse leakage current of the TA6L11AHM3/I at 9.40 V and 150 °C?
At 9.40 V stand-off voltage and 150 °C junction temperature, the TA6L11AHM3/I exhibits a maximum reverse leakage current (ID) of 5.0 µA, as specified in the Electrical Characteristics table on page 2 of the Vishay datasheet. This low leakage ensures minimal power loss and signal distortion in always-on automotive sensor circuits.
Does the TA6L11AHM3/I have polarity marking, and how is it identified?
Yes, the TA6L11AHM3/I features a cathode band marking on the body end of the SlimSMAW package. Per Vishay's mechanical drawings, this color band identifies the cathode terminal, which must be connected to the protected line. The anode is the opposite end. Polarity is critical for correct unidirectional clamping behavior-reversal would prevent proper transient suppression.
