Product details
Overview
TA6F27AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, rated for 27.0 V breakdown voltage (VBR), 23.1 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 µs). It delivers 37.5 A peak pulse current (IPPM) with 16.0 V clamping voltage (VC) and operates up to 185 °C junction temperature - designed for automotive sensor line protection against load dump and ESD.
For engineers reviewing the TA6F27AHM3_A/H datasheet, TA6F27AHM3_A/H pinout, TA6F27AHM3_A/H application, or TA6F27AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 30 kV IEC 61000-4-2 ESD rating, MSL Level 1 moisture sensitivity, and TJ = 185 °C capability for under-hood automotive electronics.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable clamping performance across temperature. Its unidirectional architecture provides low-leakage reverse blocking (1.0 µA at VWM) and precise breakdown tolerance (±5% at 1.0 mA test current), enabling reliable overvoltage protection on signal and power rails without false triggering.
The SlimSMA (DO-221AC) package supports automated placement and offers thermal resistance of RθJA = 120–150 °C/W (FR4 board) and RθJM = 12–15 °C/W (mount), ensuring effective heat dissipation during transient events while maintaining ultra-low profile (0.95 mm typical height).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 25.7 / 27.0 / 28.4 V - ensures consistent avalanche initiation above 23.1 V operating rail |
| VWM | 23.1 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 16.0 V - clamps transients to safe level for downstream 16 V-rated ICs or MOSFETs |
| IPPM (10/1000 µs) | 37.5 A - sustains high-energy surges common in automotive load-switching environments |
| PPPM | 600 W - handles standardized lightning-induced transients per ISO 7637-2 and IEC 61000-4-5 |
| TJ max | 185 °C - enables operation in engine control units, transmission modules, and other high-temp zones |
| ESD Rating | 30 kV contact/air (IEC 61000-4-2) - protects against human-body-model and system-level ESD events |
Pinout & Package
Package: SlimSMA (DO-221AC), surface-mount, halogen-free, RoHS-compliant, AEC-Q101 qualified. Cathode indicated by color band; matte tin-plated terminals meet J-STD-002 solderability standards and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage return path; defines conduction direction in unidirectional configuration |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., sensor supply); absorbs surge energy into ground via avalanche breakdown |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile (0.95 mm) | Enables use in space-constrained automotive ECUs and ADAS sensor housings without mechanical interference |
| AEC-Q101 qualification | Validates reliability for automotive-grade production, including temperature cycling, HTRB, and UHAST |
| Junction passivation design | Reduces parameter drift over time and improves long-term stability under thermal stress |
| MSL Level 1 (260 °C peak) | Allows standard reflow soldering without pre-baking, reducing manufacturing complexity and cost |
| 185 °C junction rating | Supports extended lifetime in under-hood applications where ambient temperatures exceed 125 °C |
Applications
| Automotive Sensor Protection | Power Line Transient Suppression |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors in engine management systems exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between sensor VOUT and ground to shunt transient energy before it reaches ADC input or signal conditioner. Use Value: Maintains signal integrity by limiting clamped voltage to 16.0 V, preventing latch-up or damage to 16 V-tolerant signal chain components. |
Use Scenario: Safeguarding 24 V supply rails in commercial vehicle telematics modules subjected to ISO 7637-2 Pulse 5a (load dump). IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power input, absorbing up to 600 W for 1 ms to protect DC-DC converters and microcontrollers. Use Value: Withstands 37.5 A peak surge at 23.1 V working voltage, enabling robust front-end protection without derating at elevated ambient temperatures. |
| ESD-Sensitive Interface Lines | Industrial CAN Bus Node Protection |
Use Scenario: Shielding LIN bus or analog sensor inputs in body control modules from ESD events during assembly or service. IC Role / Device Role / Timing Role: Localized ESD suppressor mounted directly at connector entry point, providing 30 kV contact discharge immunity per IEC 61000-4-2. Use Value: Low capacitance (typ. <100 pF at 0 V) avoids signal distortion on 20 kbps LIN lines while meeting automotive ESD requirements. |
Use Scenario: Protecting CAN transceiver pins (CAN_H/CAN_L) in industrial gateways operating in electrically noisy factory environments. IC Role / Device Role / Timing Role: Secondary protection stage after common-mode choke, clamping differential and common-mode transients induced by motor drives or relay switching. Use Value: Unidirectional configuration matches CAN bus DC bias; 16.0 V clamping prevents transceiver overvoltage while preserving 2.5 V logic margins. |
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 | Higher VBR (25.6–28.4 V), same SlimSMA package, but lower PPPM (400 W) and no AEC-Q101 qualification | Limited to industrial/commercial use; not validated for automotive temperature cycling or humidity testing | Select SMAJ24A only for non-automotive designs where AEC-Q101 compliance and 600 W surge handling are not required |
| TPSMF24A | Same VWM/VBR range, 600 W rating, AEC-Q101 qualified, but larger SOD-123FL package (1.7 mm height) | Requires PCB layout revision due to taller profile and different pad footprint; less suitable for ultra-thin modules | Choose TPSMF24A when higher thermal mass is needed and board height budget allows ≥1.7 mm clearance |
Compared with SMAJ24A and TPSMF24A, TA6F27AHM3_A/H uniquely combines AEC-Q101 qualification, 600 W surge rating, SlimSMA's 0.95 mm profile, and 185 °C operation - making it optimal for next-generation compact automotive electronics where space, reliability, and thermal margin are simultaneously constrained.

FAQ
What is the exact breakdown voltage tolerance for TA6F27AHM3_A/H?
The TA6F27AHM3_A/H has a specified breakdown voltage (VBR) range of 25.7 V (min) to 28.4 V (max) at 1.0 mA test current, with 27.0 V nominal. This ±5% tolerance ensures predictable clamping behavior across production lots and temperature extremes, critical for protecting 24 V automotive systems where overvoltage margins are tightly defined.
Is TA6F27AHM3_A/H compatible with lead-free reflow soldering processes?
Yes, TA6F27AHM3_A/H is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102, ensuring reliable wetting and intermetallic formation during standard Pb-free SAC305 reflow profiles without pre-baking.
Does TA6F27AHM3_A/H meet automotive qualification standards?
Yes, TA6F27AHM3_A/H is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, unbiased highly accelerated stress test (UHAST), and mechanical shock - confirming suitability for automotive powertrain, chassis, and body electronics applications.
What is the clamping voltage of TA6F27AHM3_A/H at its rated peak pulse current?
The TA6F27AHM3_A/H exhibits a maximum clamping voltage (VC) of 16.0 V at its rated peak pulse current (IPPM) of 37.5 A under 10/1000 µs waveform conditions. This low clamping level ensures downstream 16 V-rated components remain within safe operating limits during surge events.
Can TA6F27AHM3_A/H be used in bidirectional configurations?
No, TA6F27AHM3_A/H is strictly unidirectional and must be oriented with cathode toward the protected line. Bidirectional protection requires pairing two devices or selecting a dedicated bidirectional TVS such as the TA6F27CA series - using TA6F27AHM3_A/H in reverse polarity risks permanent failure.
