Product details
Overview
TA6F13AHM3/6A from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and ESD transients on signal lines and power rails. It features a breakdown voltage of 12.4–13.7 V at 1 mA, clamps to ≤18.2 V at 33.0 A (10/1000 μs), delivers 600 W peak pulse power, operates up to +185 °C junction temperature, and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the TA6F13AHM3/6A datasheet, TA6F13AHM3/6A pinout, TA6F13AHM3/6A application, or TA6F13AHM3/6A equivalent, this page provides verified package dimensions, clamping performance under standardized surge waveforms, thermal resistance data (RθJA = 145 °C/W), ESD immunity per IEC 61000-4-2 Level 4 (±15 kV air / ±8 kV contact), and DO-221AC mechanical compatibility for automated SMT placement.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature reliability and low-profile mounting. Its unidirectional architecture enables precise reverse-biased clamping with tight VBR tolerance (±5%) and low leakage (<5 μA at VWM = 11.1 V, TJ = 150 °C).
Designed for use in conjunction with ICs, MOSFETs, and sensor interfaces, it meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and exhibits stable clamping behavior across -65 °C to +185 °C operating range - critical for under-hood automotive and industrial control environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at IT = 1 mA - defines precise reverse conduction onset for predictable clamping threshold |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 5 μA |
| VC @ IPPM | ≤18.2 V at 33.0 A (10/1000 μs) - ensures downstream ICs see safe voltage during surge events |
| PPPM | 600 W - peak surge energy absorption capability under standard lightning waveform |
| TJ max | +185 °C - enables operation in high-ambient automotive engine compartments and industrial enclosures |
| RθJA | 145 °C/W - thermal resistance informs PCB pad layout requirements for sustained power dissipation |
| ESD Rating | IEC 61000-4-2 Level 4: ±15 kV (air), ±8 kV (contact) - protects against human-body model discharge events |

Applications
| Automotive LIN Bus Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: Protects LIN transceivers and microcontroller GPIOs from load-dump-induced transients and ESD in body control modules. IC Role / Device Role / Timing Role: Unidirectional TVS placed between LIN bus line and ground, clamping reverse surges while preserving signal integrity. Use Value: Maintains <11.1 V working voltage margin below LIN transceiver VCC, ensuring no false triggering during normal operation. |
Use Scenario: Shields analog outputs (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors from field wiring transients in factory automation. IC Role / Device Role / Timing Role: Standoff device mounted at sensor connector interface to absorb fast-rising inductive spikes before reaching ADC input stage. Use Value: Limits clamped voltage to ≤18.2 V, preventing damage to 24 V-rated op-amps and isolators upstream of the signal chain. |
| Consumer USB Port ESD Suppression | Power Supply Input Surge Protection |
Use Scenario: Integrated into USB 2.0 data line protection circuits for portable medical devices and smart home hubs. IC Role / Device Role / Timing Role: Low-capacitance TVS on D+/D− lines, leveraging DO-221AC's minimal parasitic capacitance for signal fidelity. Use Value: Delivers ±15 kV air-gap ESD immunity without degrading 480 Mbps data eye diagram due to compact geometry and optimized junction design. |
Use Scenario: Placed across 12 V DC input rails of embedded controllers to suppress load dump and alternator ripple surges. IC Role / Device Role / Timing Role: Primary clamping element in front-end protection stage, coordinated with fuse and common-mode choke. Use Value: Absorbs 600 W surge energy without thermal runaway, maintaining VC ≤18.2 V to safeguard downstream DC-DC converters and PMICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5AT (Vishay) | Same DO-214AC package; higher RθJA (160 °C/W); lower PPPM (400 W); VBR = 14.4–15.9 V | Less suitable for high-temperature ambient or high-energy surge environments requiring 600 W rating | Select TA6F13AHM3/6A when >400 W surge handling or TJ = 185 °C operation is required |
| 1.5SMC13A (ON Semiconductor) | DO-214AB package (larger footprint); same VBR range; PPPM = 1500 W; RθJA = 125 °C/W; not AEC-Q101 qualified | Better for high-power industrial AC/DC inputs but incompatible with space-constrained automotive PCBs | Choose TA6F13AHM3/6A for automotive AEC-Q101 compliance and SlimSMA board area savings |
Compared with SMAJ13A-E3/5AT and 1.5SMC13A, TA6F13AHM3/6A uniquely combines AEC-Q101 qualification, 600 W surge rating, 0.95 mm height, and 185 °C junction capability in the DO-221AC footprint - making it optimal for next-generation automotive and high-density industrial designs where thermal, space, and reliability constraints converge.
