Product details
Overview
TA6F13AHM3/6B from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching transients and ESD events on signal lines and power rails. It features a 12.4 V to 13.7 V breakdown voltage (VBR), 11.1 V standoff voltage (VWM), 600 W peak pulse power (10/1000 µs), 18.2 V clamping voltage at 33.0 A peak surge current, and operates up to 185 °C junction temperature - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the TA6F13AHM3/6B datasheet, TA6F13AHM3/6B pinout, TA6F13AHM3/6B application, or TA6F13AHM3/6B equivalent, key selection criteria include unidirectional clamping behavior, DO-221AC (SlimSMA) package compatibility, AEC-Q101 qualification, IEC 61000-4-2 Level 4 ESD robustness (±15 kV air / ±8 kV contact), and thermal resistance (RθJA = 145 °C/W).
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation under thermal stress. Its unidirectional architecture enables precise forward-biased clamping during overvoltage events while maintaining low leakage (<2 µA at VWM) and stable VBR across temperature.
The device is rated for 185 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. Its DO-221AC package delivers ultra-low profile (0.95 mm typical height) and supports automated placement in space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 12.4 V min / 13.7 V max at 1.0 mA - defines minimum voltage at which clamping initiates reliably |
| Standoff Voltage VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 2 µA |
| Clamping Voltage VC | 18.2 V at 33.0 A IPPM (10/1000 µs) - limits downstream voltage during surge |
| Peak Pulse Power | 600 W (10/1000 µs waveform) - determines transient energy absorption capability |
| Junction Temperature Range | –65 °C to +185 °C - enables use in under-hood automotive and industrial environments |
| ESD Rating | IEC 61000-4-2 Level 4: ±15 kV air / ±8 kV contact - protects against human-body-model discharges |
| Thermal Resistance RθJA | 145 °C/W - informs derating requirements on standard FR-4 PCB with minimum pad layout |
Pinout & Package
Package: DO-221AC (SlimSMA), ultra-low-profile surface-mount case with matte tin-plated terminals; cathode denoted by color band; halogen-free, RoHS-compliant, AEC-Q101 qualified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; conducts during reverse-transient clamping |
| Cathode | Clamping reference terminal | Marked with color band; tied to higher-potential rail (e.g., VCC or signal high); defines clamping threshold relative to this node |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile height | 0.95 mm typical - enables routing under connectors and in thin-profile enclosures |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
| Passivated anisotropic rectifier design | Reduces parameter drift over time and temperature vs. conventional planar junctions |
| MSL Level 1 rating | Allows unlimited floor life and 260 °C peak reflow without baking - simplifies SMT manufacturing |
| Low junction capacitance | ~20 pF at zero bias (typ.) - minimizes signal distortion on high-speed data lines (e.g., CAN, LIN) |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Digital Input Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5A (Vishay) | Same DO-214AC package; higher RθJA (160 °C/W); VBR = 14.4–15.9 V; lower IPPM (32.2 A) | Less suitable for high-temperature PCB zones; requires larger copper area for thermal management | Select when legacy DO-214AC footprint is fixed and 185 °C operation is not required |
| TPSMF13A (STMicroelectronics) | DO-214AC package; VBR = 14.4 V min; clamping VC = 21.5 V @ 27.8 A; AEC-Q101 qualified; higher capacitance (~40 pF) | Higher clamping voltage reduces margin for 3.3 V/5 V logic protection; less optimal for high-speed buses | Choose only if dual-source supply chain diversification is prioritized over clamping voltage and capacitance |
Compared with SMAJ13A-E3/5A and TPSMF13A, TA6F13AHM3/6B offers superior thermal capability (185 °C TJ max), lower clamping voltage (18.2 V), lower junction capacitance, and tighter VBR tolerance - making it preferred for automotive and high-density industrial designs where thermal headroom and signal fidelity are critical.
