Product details
Overview
TA6F24AHM3/6A from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching transients and ESD events on power rails and signal lines. It features a breakdown voltage of 22.8–25.2 V at 1 mA, clamps to ≤33.2 V at 18.1 A (10/1000 μs), delivers 600 W peak pulse power, and operates up to 185 °C junction temperature - ideal for automotive power rail protection in engine control units and body electronics.
For engineers reviewing the TA6F24AHM3/6A datasheet, TA6F24AHM3/6A pinout, TA6F24AHM3/6A application, or TA6F24AHM3/6A equivalent, key selection criteria include unidirectional polarity, DO-221AC (SlimSMA) package compatibility with automated placement, AEC-Q101 qualification, IEC 61000-4-2 Level 4 ESD rating (15 kV air / 8 kV contact), and thermal resistance (RθJA = 145 °C/W).
Technical Context
The TA6F24AHM3/6A employs passivated anisotropic rectifier technology optimized for high-temperature stability and low-profile mounting. Its unidirectional architecture provides precise reverse-biased clamping with tight VBR tolerance (±5%) and low leakage (<1 μA at 20.5 V, TJ = 150 °C).
Designed for high-reliability automotive environments, it supports continuous operation at TJ = 185 °C, meets MSL Level 1 per J-STD-020 (260 °C reflow peak), and achieves 6 W power dissipation at TM = 65 °C on infinite heat sink - enabling robust surge handling without derating in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at 1 mA - defines precise clamping onset threshold for overvoltage detection |
| VWM | 20.5 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | ≤33.2 V at 18.1 A (10/1000 μs) - ensures protected ICs see no more than 33.2 V during worst-case surge |
| PPPM | 600 W (10/1000 μs) - sustains high-energy transients common in automotive load-dump and inductive kick scenarios |
| TJ max | 185 °C - enables under-hood deployment without thermal derating in engine compartment applications |
| ESD Rating | IEC 61000-4-2 Level 4: 15 kV air / 8 kV contact - protects against human-body model discharges in assembly and field use |
| RθJA | 145 °C/W - determines board-level thermal design margin when mounted on FR-4 with minimum pad layout |
Pinout & Package
Package: DO-221AC (SlimSMA), ultra-low-profile surface-mount case with matte tin-plated terminals, halogen-free, RoHS-compliant, and AEC-Q101 qualified. Overall height: 0.95 mm typical.

| Uni-directional polarity only | Simplifies circuit design for DC-biased rails (e.g., 24 V supply) where reverse conduction is not required |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Clamping |
|---|---|

Use Scenario: Protecting 24 V supply inputs in engine control units (ECUs) against ISO 7637-2 load dump and inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between 24 V rail and ground to clamp transients below IC absolute maximum ratings. Use Value: Limits clamped voltage to ≤33.2 V during 18.1 A surges, preserving MCU, gate drivers, and analog front-ends rated for 36 V max. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loop) in industrial pressure sensors exposed to cable-induced surges. IC Role / Device Role / Timing Role: Low-capacitance TVS placed across signal and return to absorb fast transients without distorting low-bandwidth analog signals. Use Value: Delivers 600 W surge capability with <1 μA leakage at 20.5 V, ensuring minimal impact on loop accuracy and long-term calibration stability. |
| Telecom DC Power Input Protection | Consumer Appliance Motor Drive Protection |
|

IC Role / Device Role / Timing Role: Unidirectional TVS configured cathode-to-rail to clamp negative-going transients on negative supply lines. Use Value: Maintains 185 °C TJ rating and AEC-Q101 reliability for extended service life in uncooled outdoor enclosures. |
Use Scenario: Suppressing back-EMF from brushed DC motors in smart home appliances (e.g., vacuum cleaners, washing machines). IC Role / Device Role / Timing Role: TVS placed across motor terminals to divert inductive energy away from H-bridge MOSFETs and microcontroller GPIOs. Use Value: Withstands repeated 600 W pulses and operates reliably at 145 °C/W ambient rise, preventing MOSFET avalanche failure during frequent motor commutation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T (Vishay) | Same DO-214AC package; higher RθJA (175 °C/W); lower PPPM (400 W); VC = 38.9 V @ 10.3 A | Limited to lower-energy transients; less suitable for automotive load-dump compliance | Select when cost sensitivity outweighs peak surge requirement and thermal margin is sufficient |
| TPSMD24 (Texas Instruments) | DO-214AB package (larger footprint); AEC-Q101 qualified; VC = 35.5 V @ 16.9 A; PPPM = 600 W | Requires PCB redesign due to different pad layout and 2.5 mm height vs. 0.95 mm | Choose only if existing design uses SMA package and height constraint is not binding |
Compared with SMAJ24A-E3/57T and TPSMD24, the TA6F24AHM3/6A offers superior thermal performance (RθJA = 145 °C/W), lower profile (0.95 mm), and tighter clamping (33.2 V), making it optimal for next-generation automotive modules where space, thermal headroom, and strict voltage ceilings are critical.

FAQ
What is the breakdown voltage range of the TA6F24AHM3/6A?
The TA6F24AHM3/6A has a guaranteed breakdown voltage (VBR) range of 22.8 V to 25.2 V at 1 mA test current, measured per JEDEC standards. This tight ±5% tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage detection in 24 V system designs. The TA6F24AHM3/6A maintains this specification across its full operating temperature range.
Is the TA6F24AHM3/6A suitable for automotive applications?
Yes, the TA6F24AHM3/6A is AEC-Q101 qualified and rated for junction temperatures up to 185 °C, making it suitable for under-hood automotive applications including engine control units, body control modules, and ADAS power supplies. Its DO-221AC package supports automated placement, and its MSL Level 1 rating allows standard lead-free reflow - all verified per the official Vishay qualification report for TA6F24AHM3/6A.
What is the clamping voltage of the TA6F24AHM3/6A under surge conditions?
The TA6F24AHM3/6A clamps to a maximum of 33.2 V at 18.1 A peak pulse current (10/1000 μs waveform). This value is specified in the Vishay datasheet and represents the upper limit of voltage seen by downstream circuitry during worst-case transient events. The TA6F24AHM3/6A achieves this performance while maintaining low leakage and high thermal stability.
Does the TA6F24AHM3/6A have ESD protection capability?
Yes, the TA6F24AHM3/6A meets IEC 61000-4-2 Level 4 ESD immunity: 15 kV (air discharge) and 8 kV (contact discharge). This rating is confirmed in the Vishay datasheet and applies directly to the TA6F24AHM3/6A device, enabling use in environments where static discharge poses a risk to sensitive electronics during handling or operation.
What package type does the TA6F24AHM3/6A use?
The TA6F24AHM3/6A uses the DO-221AC (SlimSMA) surface-mount package, measuring 0.163–0.171 inches in length, 0.098–0.106 inches in width, and just 0.039 inches (0.95 mm) in height.
