Product details
Overview
TA6F8.2AHM3/6A from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-221AC (SlimSMA) package, featuring 7.79 V to 8.61 V breakdown voltage (VBR), 7.02 V standoff voltage (VWM), 12.1 V clamping voltage at 49.6 A peak pulse current, 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TA6F8.2AHM3/6A datasheet, TA6F8.2AHM3/6A pinout, TA6F8.2AHM3/6A application, or TA6F8.2AHM3/6A equivalent, this device serves as a high-temperature-stable, low-profile (0.95 mm height) ESD and surge protection solution for sensitive signal lines in automotive sensor units, industrial I/O interfaces, and telecommunication front-end circuits.
Technical Context
This TVS diode operates under unidirectional polarity with junction passivated anisotropic rectifier technology, enabling stable clamping performance up to 185 °C junction temperature. Its thermal resistance is 145 °C/W (junction-to-ambient) and 20 °C/W (junction-to-mount), supporting reliable operation on minimum recommended FR-4 pad layout or infinite heatsink mounting.
The device delivers 12.1 V clamping voltage at 49.6 A (10/1000 μs waveform), with ≤100 μA reverse leakage at VWM and 10 mA test current, meeting IEC 61000-4-2 Level 4 ESD immunity (15 kV air / 8 kV contact) and MSL Level 1 reflow compatibility (260 °C peak).
Key Specifications

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 | Higher VBR (7.6–8.4 V), same DO-214AC package, 600 W rating, but not AEC-Q101 qualified | Limited to industrial/commercial use; lacks automotive qualification and 185 °C TJ rating | Select when AEC-Q101 is not required and board space allows larger DO-214AC footprint |
| TPSMF8.0A | Same VBR range (7.6–8.4 V), DO-214AC, 600 W, AEC-Q101 qualified, but 1.2 mm height vs. 0.95 mm | Acceptable for automotive use but adds 0.25 mm height-critical in ultra-thin modules like ADAS cameras | Choose if existing DO-214AC footprint is fixed and height constraint is relaxed |
Compared with SMAJ8.0A and TPSMF8.0A, TA6F8.2AHM3/6A offers the lowest profile (0.95 mm), highest junction temperature rating (185 °C), and identical AEC-Q101 qualification-making it optimal for next-generation compact automotive electronics where thermal headroom and board real estate are tightly constrained.

FAQ
What is the exact breakdown voltage range for TA6F8.2AHM3/6A?
The TA6F8.2AHM3/6A has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at 10 mA test current, measured per JEDEC standards. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage protection design for 5 V–7 V signal rails. The TA6F8.2AHM3/6A datasheet specifies these values under controlled conditions at TA = 25 °C.
Is TA6F8.2AHM3/6A suitable for automotive applications?
Yes, TA6F8.2AHM3/6A is AEC-Q101 qualified and rated for junction temperatures up to 185 °C, making it suitable for under-hood and cabin-mounted automotive electronics. It meets IEC 61000-4-2 Level 4 ESD immunity and supports reflow profiles up to 260 °C (MSL Level 1). The TA6F8.2AHM3/6A is widely used in engine control units, ADAS camera modules, and body control modules.
What is the clamping voltage of TA6F8.2AHM3/6A at its rated peak pulse current?
The TA6F8.2AHM3/6A clamps to a maximum of 12.1 V at 49.6 A peak pulse current (10/1000 μs waveform), as specified in the Vishay datasheet. This value reflects worst-case performance under standardized surge conditions and ensures downstream components-such as microcontrollers or transceivers-are held below their absolute maximum voltage ratings during transient events.
Does TA6F8.2AHM3/6A have unidirectional or bidirectional polarity?
TA6F8.2AHM3/6A is strictly unidirectional, with cathode identified by a color band on the DO-221AC package. It conducts only when the cathode is at higher potential than the anode, making it appropriate for DC-biased signal lines like CAN, LIN, or sensor outputs. Bidirectional variants (e.g., TA6F8.2CA) are separate part numbers and not interchangeable with TA6F8.2AHM3/6A.
What packaging format is supplied for TA6F8.2AHM3/6A?
TA6F8.2AHM3/6A is supplied in 7-inch plastic tape and reel format with a base quantity of 3,500 units per reel (package code "6A"). The HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. Tape-and-reel packaging supports high-speed automated pick-and-place assembly without manual handling or contamination risk.
