Product details
Overview
TA6F27AHM3/6A from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and ESD events on power and signal lines. It features a breakdown voltage of 25.7–28.4 V at 1 mA, 37.5 V maximum clamping voltage at 16.0 A peak pulse current (10/1000 μs), 600 W peak pulse power rating, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TA6F27AHM3/6A datasheet, TA6F27AHM3/6A pinout, TA6F27AHM3/6A application, or TA6F27AHM3/6A equivalent, key selection criteria include its DO-221AC (SlimSMA) package, 185 °C max junction temperature, 23.1 V stand-off voltage, 1.0 μA reverse leakage at VWM, and suitability for high-reliability sensor interface and MOSFET gate protection in constrained PCB layouts.
Technical Context
The TA6F27AHM3/6A employs passivated anisotropic rectifier technology optimized for low-profile, high-temperature operation up to TJ = 185 °C. Its unidirectional architecture provides precise clamping with tight VBR tolerance (±5%) and low dynamic impedance, enabling fast response to transients induced by inductive load switching.
Designed for automated SMT placement, it meets JESD22-B102 solderability and JESD201 Class 2 whisker resistance requirements. The device delivers 600 W peak pulse power under 10/1000 μs waveform while maintaining MSL Level 1 moisture sensitivity and UL 94 V-0 flammability compliance in its SlimSMA molding compound.
Key Specifications

Use Scenario: Gate protection for N-channel MOSFETs driving BLDC motors in smart HVAC and washing machine inverters. IC Role / Device Role / Timing Role: Low-capacitance TVS placed across MOSFET source-drain to suppress Miller-induced voltage spikes during high-dI/dt switching. Use Value: Prevents false turn-on and gate oxide stress with 37.5 V clamping ceiling, ensuring safe operation within MOSFET VDS rating margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28A | Higher VBR (26.6–29.4 V), same DO-214AC package but taller (2.3 mm vs. 0.95 mm) | Larger footprint and height limit use in ultra-low-profile assemblies; lower thermal resistance (RθJA = 100 °C/W) | Select SMAJ28A only when board height > 2.0 mm is acceptable and higher power dissipation margin is required. |
| 1.5SMC27A | Same VBR range (25.7–28.4 V), larger DO-214AB package (3.5 mm height), 1500 W PPPM rating | Requires more PCB area and cannot fit in SlimSMA-optimized layouts; suited for higher-energy surge environments | Choose 1.5SMC27A when surge threat level exceeds 600 W and mechanical clearance allows larger body size. |
Compared with SMAJ28A and 1.5SMC27A, the TA6F27AHM3/6A uniquely balances AEC-Q101 qualification, 0.95 mm profile, and 600 W capability-making it optimal for space-limited automotive and industrial modules where height and reliability are co-constrained.

FAQ
What is the exact breakdown voltage range for TA6F27AHM3/6A?
The TA6F27AHM3/6A has a guaranteed breakdown voltage (VBR) range of 25.7 V to 28.4 V measured at 1 mA test current, per the Vishay datasheet revision 18-Apr-16. This tight ±5% tolerance ensures consistent clamping behavior across production lots and temperature extremes up to 185 °C junction temperature.
Is TA6F27AHM3/6A qualified for automotive applications?
Yes, the TA6F27AHM3/6A is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature operating life, temperature cycling, and ESD immunity per automotive reliability standards. Its 185 °C maximum junction temperature and halogen-free HM3 construction further support under-hood and body-control module deployment.
What does the "HM3/6A" suffix mean in TA6F27AHM3/6A?
The "HM3" suffix indicates halogen-free, RoHS-compliant, and AEC-Q101-qualified construction with matte tin-plated leads meeting J-STD-002 solderability. The "6A" denotes the preferred packaging code: 7-inch plastic tape-and-reel with 3500 units per reel, optimized for high-speed SMT placement equipment.
How does TA6F27AHM3/6A compare to standard SMAJ series TVS diodes?
The TA6F27AHM3/6A offers identical electrical specs to SMAJ28A (e.g., VBR, VC, PPPM) but in a thinner DO-221AC (SlimSMA) package-0.95 mm versus 2.3 mm height. This enables use in ultra-low-profile designs where SMAJ devices cannot fit, without sacrificing AEC-Q101 qualification or surge performance.
What is the maximum clamping voltage of TA6F27AHM3/6A under surge conditions?
The TA6F27AHM3/6A exhibits a maximum clamping voltage (VC) of 37.5 V when subjected to a 10/1000 μs surge waveform with peak current of 16.0 A. This value is guaranteed across temperature and ensures protected downstream ICs remain within their absolute maximum voltage ratings during transient events.
