Product details
Overview
TA6F10AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, rated for 10 V breakdown voltage (VBR = 9.5–10.5 V at 1 mA), 8.55 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 41.4 V clamping voltage at 14.5 A peak surge current and operates up to +185 °C junction temperature, making it suitable for automotive sensor line protection against inductive switching transients.
For engineers reviewing the TA6F10AHM3_A/I datasheet, TA6F10AHM3_A/I pinout, TA6F10AHM3_A/I application, or TA6F10AHM3_A/I equivalent, this device requires attention to its unidirectional polarity, MSL Level 1 moisture sensitivity, AEC-Q101 qualification, 0.95 mm profile constraint, and thermal resistance (RθJA = 120–150 °C/W) under FR4 PCB mounting conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for high-temperature stability and reliability. Its unidirectional configuration provides low-leakage reverse blocking (IR ≤ 5.0 μA at VWM) and precise clamping response during fast-rising transients.
The device meets IEC 61000-4-2 ESD immunity up to ±30 kV (contact/air), complies with JESD22-B102 solderability and JESD201 Class 2 whisker resistance, and features matte tin-plated terminals on a UL 94 V-0 molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 / 10.0 / 10.5 V at 1 mA - defines minimum voltage at which device enters avalanche conduction; critical for ensuring clamping initiates above circuit operating voltage |
| VWM | 8.55 V - maximum continuous reverse working voltage; must exceed system's highest steady-state signal or supply rail |
| VC @ IPPM | 41.4 V at 14.5 A - clamped voltage seen by protected IC during 10/1000 μs surge; determines stress on downstream components |
| PPPM | 600 W (10/1000 μs) - peak transient energy handling capacity; defines robustness against lightning or load-dump events |
| TJ max | +185 °C - enables operation in under-hood automotive environments without derating penalties up to ambient +125 °C |
| ESD Rating | ±30 kV per IEC 61000-4-2 - qualifies for direct interface with exposed connectors or buttons in harsh industrial or vehicle cabins |
| MSL Level | Level 1 (260 °C peak reflow) - supports standard SMT assembly without dry-pack or baking requirements |
Pinout & Package
Package: SlimSMA (DO-221AC), surface-mount, unidirectional configuration with cathode indicated by color band. Dimensions: 4.15–4.35 mm length × 2.50–2.70 mm width × 0.95 mm height. Matte tin-plated terminals meet J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path during positive transients on cathode side |
| Cathode | High-side transient input terminal | Connected to protected signal or power line; avalanche conduction occurs when voltage exceeds VBR relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| 185 °C junction rating | Enables placement near heat sources (e.g., power modules or engine control units) without thermal derating in automotive applications |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, and HAST testing - required for ASIL-B/C subsystems |
| 0.95 mm profile | Reduces board space and mechanical interference in tight-fit modules such as ADAS camera housings or battery management sensors |
| Passivated anisotropic rectifier | Delivers stable VBR temperature coefficient (αT = 0.064 %/°C) and low leakage (<5 μA) across full operating range |
| MSL Level 1 compliance | Eliminates pre-reflow baking and simplifies factory logistics for high-volume Tier 1 automotive manufacturing |
Applications
| Automotive Sensor Signal Protection | Engine Control Unit (ECU) Power Rail Clamping |
|---|---|

Use Scenario: Protecting LIN/CAN transceiver I/O pins and analog sensor outputs (e.g., pressure, temperature) from load dump and inductive kickback in 12 V vehicle networks. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp positive transients while maintaining DC integrity. Use Value: Limits clamped voltage to 41.4 V, preventing damage to 5 V or 3.3 V interface ICs and preserving signal fidelity during ISO 7637-2 Pulse 1/2a events. |
Use Scenario: Safeguarding 5 V or 3.3 V regulator inputs in ECUs exposed to alternator load dump (ISO 16750-2) and jump-start surges. IC Role / Device Role / Timing Role: Primary front-end transient suppressor on main power input before LDO or buck converter. Use Value: Absorbs 600 W pulses without degradation, enabling use of smaller input capacitors and reducing BOM cost versus multi-stage protection schemes. |
| Industrial Motor Drive Feedback Lines | Automotive Camera Module ESD Protection |
|
Use Scenario: Shielding encoder quadrature signals and current-sense amplifier inputs from commutation noise in BLDC motor drives. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ < 100 pF typical) placed directly at connector entry point to minimize stub inductance. Use Value: Maintains signal edge integrity up to 1 MHz while suppressing >1 kV transients - verified per IEC 61000-4-4 EFT testing. |
Use Scenario: Hardening FAKRA or HSD cable interfaces in rear-view or surround-view cameras against ESD events during service or environmental exposure. IC Role / Device Role / Timing Role: First-line defense at connector, shunting ±30 kV contact discharge to chassis ground before reaching serializer IC. Use Value: Prevents latch-up or gate oxide damage in SerDes devices without adding series impedance that degrades 3 Gbps video eye diagram. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SlimSMA package, but lower PPPM = 400 W and VC = 16.7 V at 24.9 A; TJ max = +150 °C | Limited to non-automotive industrial use due to lack of AEC-Q101 and lower temperature rating | Select SMAJ10A only if surge energy is ≤400 W and ambient temperature remains below +105 °C |
| TPSMD10A | Higher PPPM = 1500 W, same VBR range, but larger SMA package (2.5 mm height); TJ max = +175 °C | Requires PCB real estate increase and may not fit in ultra-low-profile modules like camera housings | Choose TPSMD10A when system-level surge testing exceeds 600 W or when extended thermal margin is needed beyond +125 °C ambient |
Compared with SMAJ10A and TPSMD10A, TA6F10AHM3_A/I uniquely balances AEC-Q101 compliance, 185 °C operation, and 0.95 mm height - making it the only option qualified for next-gen automotive vision systems where space, temperature, and qualification are simultaneously constrained.

FAQ
What is the exact breakdown voltage range for TA6F10AHM3_A/I?
The TA6F10AHM3_A/I has a guaranteed breakdown voltage (VBR) range of 9.5 V to 10.5 V at 1.0 mA test current, as specified in the Vishay datasheet revision 16-Jan-2025 (Document Number: 89939). This tolerance ensures reliable triggering above nominal 8.55 V stand-off voltage while avoiding premature conduction during normal operation.
Is TA6F10AHM3_A/I qualified for automotive applications?
Yes, TA6F10AHM3_A/I is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, meeting requirements for under-hood and cabin-mounted automotive electronics. Its construction includes halogen-free, RoHS-compliant materials and passes JESD201 Class 2 whisker testing - all confirmed in the official Vishay documentation.
What does the "HM3_A/I" suffix indicate in TA6F10AHM3_A/I?
The "HM3" denotes the SlimSMA (DO-221AC) package with halogen-free, RoHS-compliant molding compound; "A" is the revision code; and "I" specifies 13-inch tape-and-reel packaging with 14,000 units per reel. This matches the ordering information table in the Vishay datasheet for TA6F10AHM3_A/I.
Can TA6F10AHM3_A/I be used in bidirectional configurations?
No, TA6F10AHM3_A/I is strictly unidirectional, as confirmed by its polarity marking (cathode band), electrical characteristics table, and application notes. For bidirectional protection, Vishay offers separate part numbers such as the TA6F10CA series - TA6F10AHM3_A/I must be oriented with cathode toward the protected line.
What is the thermal resistance of TA6F10AHM3_A/I on a standard FR4 PCB?
Per the Vishay datasheet, TA6F10AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on an FR4 PCB with the minimum recommended pad layout. Maximum RθJA is 150 °C/W under the same conditions - critical for calculating safe power dissipation at elevated ambient temperatures.
