Product details
Overview
TA6F24AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, featuring 24.0 V nominal breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability. It clamps transients to ≤18.1 V at 33.2 A peak surge current and operates up to +185 °C junction temperature.
For engineers reviewing the TA6F24AHM3_A/I datasheet, TA6F24AHM3_A/I pinout, TA6F24AHM3_A/I application, or TA6F24AHM3_A/I equivalent, this device is selected for high-temperature ESD and surge protection on automotive sensor signal lines, MOSFET gate drivers, and low-capacitance IC interfaces where compact height (0.95 mm) and MSL Level 1 reflow compatibility are critical.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive surge stress. Its unidirectional configuration enables precise reverse-biased transient suppression without forward conduction during normal operation.
Thermal design is supported by RθJA = 120–150 °C/W (FR4 board, minimum pad layout) and RθJM = 12–15 °C/W, enabling reliable operation at TJ = 185 °C. The device meets IEC 61000-4-2 ±30 kV contact/air discharge and complies with JESD22-B102 solderability and JESD201 Class 2 whisker resistance.

Use Value: Limits rail voltage to ≤18.1 V during 600 W surge events, avoiding overvoltage shutdown or MOSFET avalanche failure in connected power stages. |
| MOSFET Gate Driver Protection | ADAS Camera Interface ESD Suppression |
|
Use Scenario: Shielding high-speed gate drive signals (e.g., to SiC MOSFETs) from ESD and fast-rising transients induced by nearby high-di/dt switching. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed at driver output to suppress sub-100 ns ESD pulses without distorting gate edge timing. Use Value: Maintains gate drive fidelity with <1 pF junction capacitance (per Fig. 4) while surviving ±30 kV IEC 61000-4-2 contact discharge. |
Use Scenario: Hardening FPD-Link or GMSL serial video interfaces in surround-view camera modules against cable-discharge events and hot-plug transients. IC Role / Device Role / Timing Role: Signal-line TVS on differential pairs to clamp common-mode surges without disrupting high-speed data transmission. Use Value: Provides robust ±30 kV ESD immunity while adding <0.1 dB insertion loss at 3 GHz, preserving video signal integrity per automotive EMC standards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | Same VWM (20.5 V), but lower PPPM (400 W), higher VC (38.9 V), and no AEC-Q101 qualification | Limited to industrial/commercial use; not validated for automotive temperature cycling or lifetime reliability | Select SMAJ24A only for cost-sensitive non-automotive designs where 600 W surge headroom and +185 °C operation are unnecessary |
| TPSMD24 | Higher VC (35.5 V), lower IPPM (22.5 A), and larger SMA package (1.7 mm height) vs. SlimSMA's 0.95 mm | Less suitable for space-constrained ADAS modules; lacks JESD201 Class 2 whisker resistance | Choose TPSMD24 if board-level rework tolerance is prioritized over profile and automotive qualification |
Compared with SMAJ24A and TPSMD24, the TA6F24AHM3_A/I delivers superior surge robustness (600 W), tighter clamping (18.1 V), and automotive-grade reliability in a low-profile package-making it optimal for next-generation 24 V vehicle networks where thermal margin, PCB real estate, and qualification compliance are non-negotiable.

FAQ
What is the maximum clamping voltage of the TA6F24AHM3_A/I at its rated peak pulse current?
The TA6F24AHM3_A/I has a maximum clamping voltage (VC) of 18.1 V when subjected to its rated peak pulse current (IPPM) of 33.2 A under a 10/1000 μs waveform. This value is measured per the test conditions defined in Vishay Document Number 89939 and ensures downstream circuitry remains within safe operating limits during surge events. The TA6F24AHM3_A/I maintains this clamping performance across its full operational temperature range.
Is the TA6F24AHM3_A/I qualified for automotive applications?
Yes, the TA6F24AHM3_A/I is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing required for automotive electronic components. This qualification confirms its suitability for use in engine control units, ADAS modules, and other safety-critical vehicle systems where reliability under extreme thermal and electrical conditions is mandatory. The TA6F24AHM3_A/I also supports junction temperatures up to +185 °C.
What does the "HM3_A/I" suffix indicate in TA6F24AHM3_A/I?
The "HM3_A/I" suffix in TA6F24AHM3_A/I specifies the packaging and reel configuration: "HM3" denotes the SlimSMA (DO-221AC) package with halogen-free, RoHS-compliant molding compound; "A" is the revision code; and "I" indicates 13-inch diameter plastic tape-and-reel packaging containing 14,000 units per reel. This format ensures compatibility with high-speed pick-and-place equipment and meets J-STD-020 MSL Level 1 handling requirements. The TA6F24AHM3_A/I is fully traceable and factory-verified per Vishay's quality protocols.
How does the TA6F24AHM3_A/I compare to standard SMA-package TVS diodes in terms of board space and thermal performance?
The TA6F24AHM3_A/I uses the SlimSMA (DO-221AC) package, which is significantly lower in profile (0.95 mm typical height) than standard SMA packages (~1.7 mm), saving vertical space in stacked or enclosed automotive modules. Its thermal resistance RθJM is 12–15 °C/W, enabling more efficient heat transfer to the PCB mount pad compared to legacy SMA devices. These features make the TA6F24AHM3_A/I especially advantageous in dense layouts such as radar control boards or battery management systems where both height constraints and thermal management are critical. The TA6F24AHM3_A/I also offers tighter VBR tolerance and lower leakage than many SMA alternatives.
Does the TA6F24AHM3_A/I meet industry standards for electrostatic discharge protection?
Yes, the TA6F24AHM3_A/I meets IEC 61000-4-2 for electrostatic discharge immunity with ±30 kV contact discharge and ±30 kV air discharge ratings. This level of ESD protection is validated per the test methodology specified in Vishay Document Number 89939 and is sufficient to safeguard sensitive automotive electronics-including sensor interfaces and camera links-from human-body-model and cable-discharge events. The TA6F24AHM3_A/I achieves this without compromising clamping voltage or surge capacity, making it a single-component solution for both ESD and surge protection in demanding environments.
