Product details
Overview
TA6F16AHM3/6A from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 15.2–16.8 V breakdown voltage (VBR), 13.6 V standoff voltage (VWM), 600 W peak pulse power (10/1000 μs), 22.5 V clamping voltage at 26.7 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TA6F16AHM3/6A datasheet, TA6F16AHM3/6A pinout, TA6F16AHM3/6A application, or TA6F16AHM3/6A equivalent, this device is selected for high-temperature (TJ = 185 °C), low-profile (0.95 mm height), automated-placement-ready protection of MOSFETs, ICs, and sensor signal lines in industrial and automotive systems where ESD immunity (IEC 61000-4-2 Level 4) and MSL-1 reflow compatibility are required.
Technical Context
The TA6F16AHM3/6A employs passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive surge stress. Its DO-221AC (SlimSMA) package enables compact layout while maintaining thermal resistance of 145 °C/W (junction-to-ambient) and 20 °C/W (junction-to-mount).
It operates as a unidirectional avalanche diode with defined polarity (cathode marked by color band), rated for non-repetitive 10/1000 μs pulses up to 600 W, and derated linearly above 25 °C ambient per published curves. Clamping performance is specified at IPPM = 26.7 A, delivering VC = 22.5 V - critical for protecting 12–15 V rail interfaces without overvoltage overshoot.

FAQ
What is the maximum clamping voltage of the TA6F16AHM3/6A under a 10/1000 μs surge?
The TA6F16AHM3/6A has a maximum clamping voltage (VC) of 22.5 V at a peak pulse current (IPPM) of 26.7 A, measured under the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and ensures protected circuits remain within safe voltage margins during surge events. The TA6F16AHM3/6A maintains this clamping performance due to its passivated anisotropic rectifier structure and low dynamic impedance.
Is the TA6F16AHM3/6A suitable for automotive under-hood applications?
Yes, the TA6F16AHM3/6A is AEC-Q101 qualified and rated for a maximum junction temperature of 185 °C, making it suitable for under-hood automotive applications such as engine control units, transmission control modules, and ADAS sensor power conditioning. Its DO-221AC package supports MSL Level 1 reflow and withstands thermal cycling per automotive requirements. The TA6F16AHM3/6A also meets IEC 61000-4-2 Level 4 ESD immunity, critical for field-deployed vehicle electronics.
What does the "HM3/6A" suffix indicate in TA6F16AHM3/6A?
The "HM3" suffix denotes Vishay's halogen-free, RoHS-compliant, and AEC-Q101-qualified base construction, while "6A" specifies the packaging format: 7-inch diameter plastic tape and reel containing 3,500 units. This ordering code ensures traceability, compliance, and compatibility with high-speed SMT pick-and-place equipment. The TA6F16AHM3/6A is shipped in this configuration with full material declarations per Vishay document #99912.
How does the TA6F16AHM3/6A compare to standard SMA-package TVS diodes in terms of board space?
The TA6F16AHM3/6A uses the DO-221AC (SlimSMA) package, which is 0.95 mm tall - significantly lower than the 2.3 mm height of standard DO-214AC (SMA) packages. Its footprint is also reduced: 4.15–4.35 mm length × 2.50–2.70 mm width versus typical SMA dimensions of 4.5 × 2.7 mm. This saves vertical clearance and PCB area, especially valuable in stacked or ultra-thin modules. The TA6F16AHM3/6A achieves this without sacrificing surge rating (600 W) or thermal performance.
Does the TA6F16AHM3/6A require a heatsink for 600 W pulse handling?
No, the 600 W peak pulse power rating for the TA6F16AHM3/6A is specified for a non-repetitive 10/1000 μs waveform and does not require an external heatsink. The rating assumes operation on the minimum recommended pad layout per Vishay's datasheet. However, for repetitive surges or elevated ambient temperatures, thermal design should consider its RθJA of 145 °C/W and RθJM of 20 °C/W. The TA6F16AHM3/6A is optimized for short-duration transients rather than continuous power dissipation.
