Product details
Overview
TA6F15AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, featuring 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 28.3 V clamping voltage at 21.2 A peak surge current, and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the TA6F15AHM3_A/H datasheet, TA6F15AHM3_A/H pinout, TA6F15AHM3_A/H application, or TA6F15AHM3_A/H equivalent, this device is selected for high-reliability transient suppression on signal lines and power rails where low-profile mounting, 185 °C junction capability, and IEC 61000-4-2 ±30 kV ESD robustness are required.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance across temperature. Its unidirectional configuration enables precise reverse-biased transient suppression on DC-biased lines, with thermal resistance RθJA of 120–150 °C/W and RθJM of 12–15 °C/W under JEDEC-compliant test conditions.
The device operates over -65 °C to +185 °C junction temperature range and maintains specified VBR stability via a temperature coefficient of +0.076 %/°C. It meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing on matte tin-plated terminals.

Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors in engine bay modules exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and ECU input to clamp transients before they reach precision ADC front-end. Use Value: Maintains signal integrity with 28.3 V clamping at 21.2 A, preventing ADC saturation and ensuring compliance with ISO 16750-2. |
Use Scenario: Suppressing load-dump spikes on 12 V supply rails feeding microcontrollers and communication ICs in body control modules. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing up to 600 W of transient energy within microseconds to prevent brownout or latch-up. Use Value: Withstands 185 °C junction temperature and delivers stable VBR drift of only +0.076 %/°C, ensuring consistent protection across thermal cycles. |
| CAN/LIN Bus Line Protection | Infotainment Interface Protection |
|
Use Scenario: Guarding CAN H/L differential pairs against ESD and coupled transients in vehicle networking gateways and telematics units. IC Role / Device Role / Timing Role: One TA6F15AHM3_A/H per line (cathode to bus, anode to ground) providing fast response (<1 ns) and low capacitance. Use Value: ±30 kV IEC 61000-4-2 ESD immunity and 12.8 V VWM ensure no disruption to CAN FD signaling integrity during hot-plug events. |
Use Scenario: Shielding USB, audio, and display interface lines in head units and digital clusters from human-body-model ESD and board-level coupling. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed at connector entry point to shunt transients before reaching PHY or codec ICs. Use Value: SlimSMA footprint allows dense routing near connectors; 0.95 mm height avoids interference with flex cables and metal shielding cans. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Same VWM/VBR range but SMB (DO-214AA) package; 1.7 mm height vs. 0.95 mm; RθJA = 140 °C/W | Less suitable for ultra-thin modules; requires larger PCB area and higher thermal margin | Select when existing layout uses SMB footprint and height constraint is not critical |
| TPSMF15A | Same SlimSMA package but lower PPPM (400 W); VC = 25.1 V @ 16.7 A; AEC-Q101 qualified | Lower surge capacity limits use to less severe transients (e.g., IEC 61000-4-2 only, not ISO 7637-2) | Select when cost sensitivity outweighs need for full 600 W rating and board space is identical |
Compared with SMBJ15A and TPSMF15A, the TA6F15AHM3_A/H delivers superior surge robustness in the same ultra-low-profile SlimSMA package, making it optimal for next-generation automotive modules where thermal performance, height, and transient margin are simultaneously constrained.

Is the TA6F15AHM3_A/H compatible with lead-free reflow processes?
Yes, the TA6F15AHM3_A/H is rated for MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, making it fully compatible with standard lead-free reflow profiles. Its matte tin-plated terminals meet J-STD-002 solderability requirements, and the device passes JESD201 Class 2 whisker testing-ensuring robust interconnect reliability after assembly.
Does the TA6F15AHM3_A/H meet automotive qualification standards?
Yes, the TA6F15AHM3_A/H is AEC-Q101 qualified, confirming compliance with stress tests including high-temperature operating life, temperature cycling, and ESD. It is explicitly listed in Vishay's AEC-Q101 certified product portfolio (Document Number 89939, Revision 16-Jan-2025), and supports automotive applications such as engine control, body electronics, and ADAS subsystems.
What is the clamping voltage of the TA6F15AHM3_A/H at its rated peak pulse current?
The TA6F15AHM3_A/H exhibits a maximum clamping voltage (VC) of 28.3 V at its rated peak pulse current (IPPM) of 21.2 A under the standard 10/1000 µs waveform. This value is measured per Figure 3 in the datasheet and ensures downstream components like microcontrollers and transceivers remain within safe operating voltage margins during transient events.
How does the TA6F15AHM3_A/H differ from the TA6F15A base part number?
The TA6F15AHM3_A/H specifies the SlimSMA (DO-221AC) package in tape-and-reel format (7" reel, 3500 pcs), with halogen-free, RoHS-compliant construction and AEC-Q101 qualification. The "HM3_A/H" suffix denotes the packaging and environmental compliance variant; electrically and thermally, the TA6F15AHM3_A/H is identical to the TA6F15A base device described in the same datasheet family.
