Product details
Overview
TA6F11AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, featuring 11.0 V nominal breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 38.5 V clamping voltage at 15.6 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs). It is AEC-Q101 qualified and rated for automotive sensor line protection against inductive switching transients.
For engineers reviewing the TA6F11AHM3_A/I datasheet, TA6F11AHM3_A/I pinout, TA6F11AHM3_A/I application, or TA6F11AHM3_A/I equivalent, this device delivers high-reliability ESD immunity (30 kV IEC 61000-4-2), 185 °C maximum junction temperature, low-profile 0.95 mm height, and MSL Level 1 reflow compatibility - critical for automotive ADAS and powertrain control modules requiring robust overvoltage protection.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive surge stress. Its unidirectional configuration enables precise reverse-biased transient suppression on DC-powered signal lines without forward conduction interference.
Designed for operation up to TJ = 185 °C, it maintains specified VBR stability across automotive temperature ranges using a +0.067 %/°C temperature coefficient. Thermal resistance is characterized per JEDEC 51-2A (RθJA ≤ 150 °C/W) and JEDEC 51-14 (RθJM ≤ 15 °C/W), supporting reliable thermal performance on standard FR4 PCBs with minimum recommended pad layout.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Same VWM (9.4 V) and VC (38.5 V), but lower PPPM (400 W) and non-AEC-Q101 rated | Limited to industrial/commercial grade systems without automotive qualification requirements | Select SMAJ11A only if AEC-Q101 compliance and 600 W surge handling are not required |
| TPSMD11A | Identical electrical specs but larger SMA (DO-214AC) package (2.3 mm height), higher RθJA (180 °C/W) | Requires more board area and offers reduced thermal performance in high-density layouts | Choose TPSMD11A only when SlimSMA footprint is incompatible with existing assembly tooling |
Compared with SMAJ11A and TPSMD11A, TA6F11AHM3_A/I uniquely combines AEC-Q101 qualification, 600 W surge capability, and ultra-low 0.95 mm profile - making it the only option meeting all three criteria for next-generation automotive sensor nodes.

The TA6F11AHM3_A/I exhibits a maximum clamping voltage (VC) of 38.5 V when subjected to its rated peak pulse current of 15.6 A under a 10/1000 µs waveform. This value is measured per standard test conditions in the Vishay datasheet (Document Number: 89939) and ensures downstream ICs remain within safe operating voltage limits during surge events. The TA6F11AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is the TA6F11AHM3_A/I suitable for use in automotive applications requiring AEC-Q101 qualification?
Yes, the TA6F11AHM3_A/I is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Revision: 16-Jan-2025, Document Number: 89939). It has undergone rigorous stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST) to meet automotive reliability standards. The TA6F11AHM3_A/I is intended for deployment in engine control units, ADAS sensors, and body electronics where AEC-Q101 compliance is mandatory.
What is the thermal resistance junction-to-ambient (RθJA) for the TA6F11AHM3_A/I?
The TA6F11AHM3_A/I has a maximum RθJA of 150 °C/W when mounted on a standard FR4 PCB with the minimum recommended pad layout, per JEDEC 51-2A. Its typical RθJA is 120 °C/W. This thermal performance enables reliable operation at full power dissipation (8 W at TM = 65 °C) without external heatsinking in compact automotive modules. The TA6F11AHM3_A/I also achieves RθJM ≤ 15 °C/W per JEDEC 51-14, supporting efficient heat transfer to mounting surfaces.
Does the TA6F11AHM3_A/I have ESD protection capability, and to what standard?
Yes, the TA6F11AHM3_A/I provides system-level ESD protection rated at ±30 kV for both contact and air discharge per IEC 61000-4-2. This capability is intrinsic to its junction design and does not require external circuitry. The TA6F11AHM3_A/I delivers this performance while maintaining low leakage (<2.0 µA at VWM) and minimal capacitance, making it suitable for protecting high-speed interfaces like LIN and I²C in automotive networks.
What is the package type and physical orientation marking for the TA6F11AHM3_A/I?
The TA6F11AHM3_A/I uses the SlimSMA (DO-221AC) package - a low-profile surface-mount case measuring 0.163–0.171 inches in length and just 0.039–0.049 inches in height (0.95 mm typical). Polarity is marked by a visible cathode band on the top surface, aligned with the cathode terminal. The TA6F11AHM3_A/I's anode and cathode terminals are defined per the SlimSMA outline drawing in the Vishay datasheet, with the cathode band indicating the end connected to the protected line.
