Product details
Overview
TA6F22AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, featuring 22.0 V nominal breakdown voltage (VBR), 18.8 V stand-off voltage (VWM), 19.6 V clamping voltage at 30.6 A peak pulse current, 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the TA6F22AHM3_A/I datasheet, TA6F22AHM3_A/I pinout, TA6F22AHM3_A/I application, or TA6F22AHM3_A/I equivalent, this device is selected for high-reliability transient suppression on signal lines and power rails where low-profile mounting, TJ = 185 °C operation, and IEC 61000-4-2 ±30 kV ESD robustness are required.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive surge stress. Its unidirectional configuration provides asymmetric protection ideal for DC-biased lines such as automotive sensor supply rails and CAN transceiver I/O.
The SlimSMA (DO-221AC) package delivers thermal resistance RθJA ≤ 150 °C/W and RθJM ≤ 15 °C/W, enabling reliable operation up to TJ = 185 °C while maintaining MSL Level 1 moisture sensitivity and JESD201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-E3/5AT | Same VWM (18.8 V), but lower PPPM = 400 W and no AEC-Q101 qualification; RθJA = 180 °C/W | Limited to non-automotive industrial use; unsuitable for under-hood deployment due to lower TJ max (150 °C) | Select when cost sensitivity outweighs automotive qualification and thermal performance requirements |
| 1.5SMC22A | Higher VC = 33.2 V at same IPPM; larger SMA package (2.3 mm height); no MSL Level 1 or JESD201 whisker rating | Less suitable for space-constrained automotive modules; higher clamping voltage risks downstream component overstress | Choose only if existing PCB layout uses SMA footprint and AEC-Q101 is not mandated |
Compared with SMAJ22A-E3/5AT and 1.5SMC22A, TA6F22AHM3_A/I delivers superior automotive readiness via AEC-Q101, tighter thermal design margin (TJ = 185 °C, RθJM ≤ 15 °C/W), and lower profile-making it the preferred choice for next-generation ADAS and powertrain ECUs requiring long-term reliability in thermally aggressive environments.

Its 185 °C maximum junction temperature and SlimSMA package construction meet stringent automotive under-hood requirements. The TA6F22AHM3_A/I is explicitly designed for automotive sensor, power, and communication line protection per the Vishay product documentation.
What does the "HM3_A/I" suffix indicate in TA6F22AHM3_A/I?
The "HM3" denotes the SlimSMA (DO-221AC) package variant with halogen-free, RoHS-compliant molding compound; "A" is the revision code; and "I" specifies the 13-inch tape-and-reel packaging format with 14,000 units per reel. This differs from the "H" variant (7-inch reel, 3,500 units). The TA6F22AHM3_A/I ordering code ensures traceable, automotive-grade material flow and assembly compatibility.
Does TA6F22AHM3_A/I support automated SMT placement?
Yes, TA6F22AHM3_A/I is optimized for automated placement with its SlimSMA (DO-221AC) package: 0.95 mm typical height, matte tin-plated terminals meeting J-STD-002 solderability, and MSL Level 1 rating allowing exposure to ambient humidity without pre-baking. Its consistent cathode band marking and symmetric geometry ensure high-yield pick-and-place accuracy. The TA6F22AHM3_A/I is widely deployed in high-volume automotive PCB assembly lines.
What is the thermal resistance specification for TA6F22AHM3_A/I?
TA6F22AHM3_A/I has a typical junction-to-mount thermal resistance (RθJM) of 12 °C/W and a maximum of 15 °C/W, and a junction-to-ambient resistance (RθJA) of 120 °C/W typical and 150 °C/W maximum when mounted on the minimum recommended pad layout per JEDEC 51-2A/51-14. These values enable reliable power dissipation up to 8 W at TM = 65 °C and sustained operation at TJ = 185 °C. The TA6F22AHM3_A/I thermal performance is validated in Vishay Document Number 89939.
