Product details
Overview
TA6F7.5AHM3/6B from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and ESD events on signal lines and power rails. It features a 7.13–7.88 V breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 11.3 V clamping voltage at 53.1 A, and operates up to 185 °C junction temperature - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the TA6F7.5AHM3/6B datasheet, TA6F7.5AHM3/6B pinout, TA6F7.5AHM3/6B application, or TA6F7.5AHM3/6B equivalent, key selection criteria include unidirectional clamping behavior, DO-221AC (SlimSMA) package compatibility, AEC-Q101 qualification, 8 kV contact / 15 kV air ESD immunity per IEC 61000-4-2 Level 4, and thermal resistance of 145 °C/W (junction-to-ambient).
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation under thermal stress. Its unidirectional architecture provides low-leakage reverse blocking up to 6.40 V while delivering fast response (<1 ns) to transients exceeding 53.1 A peak pulse current.
The device is rated for 185 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its DO-221AC (SlimSMA) package enables automated placement and supports high-density PCB layouts with minimal height (0.95 mm typical).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V - ensures reliable turn-on above system operating voltage while avoiding false triggering |
| VWM | 6.40 V - maximum continuous reverse working voltage compatible with 5 V or 6 V logic/sensor supply rails |
| VC @ IPPM | 11.3 V - clamping voltage at 53.1 A limits downstream IC stress during 600 W surge events |
| PPPM (10/1000 µs) | 600 W - handles high-energy transients from relay coil switching or motor commutation |
| TJ max. | 185 °C - supports under-hood automotive and high-temperature industrial environments without derating |
| ESD rating | IEC 61000-4-2 Level 4: 8 kV contact / 15 kV air - protects against common handling and system-level ESD events |
| RθJA | 145 °C/W - defines thermal performance on standard FR-4 board with minimum pad layout |

Applications
| Automotive Sensor Interface | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between signal line and ground, responding within <1 ns to transients. Use Value: Maintains signal integrity below 11.3 V clamp level while surviving repeated 600 W surges per AEC-Q101 test conditions. |
Use Scenario: Shielding digital input channels of programmable logic controllers from inductive kickback of solenoids and relays. IC Role / Device Role / Timing Role: Standoff voltage of 6.40 V blocks normal 5 V/24 V logic levels; conducts only during >7.13 V transients. Use Value: Enables robust field wiring without external series impedance, reducing BOM count and board area vs. RC-filtered alternatives. |
| Consumer IoT Power Rail Protection | Telecom Equipment Surge Suppression |
Use Scenario: Safeguarding USB-C PD and battery management ICs in smart home hubs against ESD and hot-swap transients. IC Role / Device Role / Timing Role: First-line defense on 5 V/9 V input rails, absorbing 15 kV air discharge per IEC 61000-4-2 Level 4. Use Value: Eliminates need for secondary TVS stages due to low clamping voltage and high surge current capability (53.1 A). |
Use Scenario: Protecting Ethernet PHYs and PoE injectors from lightning-induced surges on data and power lines. IC Role / Device Role / Timing Role: Mounted adjacent to RJ45 connector or PoE controller IC to limit transient energy before it reaches silicon. Use Value: Supports sustained operation at 185 °C ambient, critical for sealed telecom enclosures with limited airflow. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | Higher VBR (6.65–7.35 V), same DO-214AC package, 400 W PPPM, no AEC-Q101 qualification | Limited to commercial/industrial use; not validated for automotive thermal cycling or humidity testing | Select when cost sensitivity outweighs automotive qualification requirements and 400 W surge capacity suffices |
| TPSMF7.0A | Same VBR range (6.65–7.35 V), DO-214AC, 400 W, AEC-Q101 qualified, but higher VC (12.5 V @ 32.4 A) | Lower surge current handling and higher clamping voltage reduce protection margin for sensitive 3.3 V/5 V ICs | Prefer where footprint compatibility with legacy SMA designs is mandatory and 12.5 V clamping is acceptable |
Compared with SMAJ7.0A and TPSMF7.0A, TA6F7.5AHM3/6B delivers higher surge robustness (600 W vs. 400 W), tighter VBR tolerance (±5% vs. ±10%), and lower clamping voltage (11.3 V vs. ≥12.5 V), enabling stronger protection for modern low-voltage ICs in automotive and industrial settings.

FAQ
What is the exact breakdown voltage range for TA6F7.5AHM3/6B?
The TA6F7.5AHM3/6B has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per the Vishay datasheet Document Number 89939. This tight ±5% tolerance ensures consistent clamping behavior across production lots and temperature extremes up to 185 °C junction temperature.
Is TA6F7.5AHM3/6B suitable for automotive applications?
Yes, TA6F7.5AHM3/6B is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C, making it suitable for under-hood and cabin-mounted automotive electronics. Its DO-221AC package, halogen-free HM3 construction, and MSL Level 1 rating further support automotive manufacturing and reliability requirements.
What does the "HM3/6B" suffix indicate in TA6F7.5AHM3/6B?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with matte tin plating meeting JESD 201 Class 2 whisker resistance. The "6B" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 14,000 units - distinct from the 7-inch "6A" variant (3,500 units).
How does TA6F7.5AHM3/6B compare to standard SMAJ-series TVS diodes?
TA6F7.5AHM3/6B offers 600 W peak pulse power (vs. 400 W for SMAJ7.0A), tighter VBR tolerance (±5% vs. ±10%), lower clamping voltage (11.3 V vs. ≥12.5 V), and full AEC-Q101 qualification - all in the same SlimSMA footprint. These advantages improve protection margin for low-voltage ICs in demanding environments.
What is the thermal resistance of TA6F7.5AHM3/6B on a standard PCB?
The TA6F7.5AHM3/6B exhibits a typical junction-to-ambient thermal resistance (RθJA) of 145 °C/W when mounted on an FR-4 board using the minimum recommended pad layout per Vishay specification. This value increases if copper area is reduced or airflow is restricted, directly impacting safe surge repetition rate.
