Product details
Overview
TA6F16AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SlimSMA (DO-221AC) package, with 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TA6F16AHM3_A/H datasheet, TA6F16AHM3_A/H pinout, TA6F16AHM3_A/H application, or TA6F16AHM3_A/H equivalent, this device serves as a high-temperature-stable clamping solution for protecting sensitive automotive sensor signal lines, MOSFET gate drivers, and microcontroller I/O against inductive switching transients and ESD up to 30 kV per IEC 61000-4-2.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable clamping under repetitive surge stress and operates reliably up to TJ = 185 °C - enabling use in under-hood automotive modules where thermal margins are constrained. Its low-profile SlimSMA package (0.95 mm typical height) supports automated placement on dense PCB layouts without compromising thermal performance.
The device exhibits a positive temperature coefficient of VBR (αT = 0.078 %/°C), ensuring predictable voltage drift across temperature, and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility. Its junction capacitance is not specified in the datasheet, confirming design focus on robust transient suppression rather than high-frequency signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V at 1.0 mA - defines precise clamping onset threshold for overvoltage protection |
| VWM | 13.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| IPPM (10/1000 μs) | 5.0 A - peak surge current it safely clamps without failure under standard lightning waveform |
| VC at IPPM | 26.7 V - clamped voltage during 5.0 A surge, limiting downstream IC stress to safe levels |
| PPPM | 600 W - energy-handling capacity for transient suppression in automotive load-dump scenarios |
| TJ max | 185 °C - enables operation in high-ambient environments such as engine control units |
| AEC-Q101 qualified | Yes - validated for automotive electronics per stress test requirements including HTRB, HTGB, and TC |

Applications
| Automotive Sensor Protection | Engine Control Unit (ECU) I/O |
|---|---|
|
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 diode placed between sensor output and MCU ADC input to clamp transients before they reach sensitive front-end circuitry. Use Value: Limits clamped voltage to 26.7 V during 5 A surges, preventing latch-up or damage to 3.3 V or 5 V ADC inputs while maintaining signal fidelity below VWM = 13.6 V. |
Use Scenario: Safeguarding digital and analog I/O pins of microcontrollers in engine control units subjected to ISO 7637-2 pulse 1, 2a, and 5a. IC Role / Device Role / Timing Role: Standoff-clamping TVS connected between each I/O line and chassis ground to absorb inductive kickback from solenoid drivers and relay coils. Use Value: Withstands 600 W peak pulse power and operates up to 185 °C, ensuring long-term reliability in high-temperature ECU enclosures without thermal shutdown. |
| Body Control Module (BCM) Signal Lines | Infotainment System Interface Protection |
|
Use Scenario: Shielding LIN bus and PWM-controlled lighting outputs in body control modules from ESD events and cable discharge. IC Role / Device Role / Timing Role: Cathode tied to LIN data line, anode to ground - provides fast (<1 ns response) clamping during contact discharge up to 30 kV. Use Value: Meets AEC-Q101 and IEC 61000-4-2 requirements simultaneously, reducing BOM count by eliminating separate ESD and surge devices. |
Use Scenario: Protecting USB, I²C, and UART interfaces in automotive infotainment head units from hot-plug transients and board-level ESD. IC Role / Device Role / Timing Role: Low-capacitance-unspecified but low-leakage TVS placed inline on bidirectional data lines to suppress surges without signal distortion. Use Value: Maintains <1.0 μA leakage at 13.6 V, avoiding DC loading on pull-up/pull-down networks critical for open-drain bus protocols. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VBR range (16.7–17.9 V), but lower PPPM = 400 W and TJ max = 150 °C | Limited to under-hood ambient ≤125 °C; unsuitable for direct replacement in high-temp ECU designs | Select SMAJ16A only if thermal margin allows and peak surge energy is ≤400 W |
| 1.5SMC16A | Higher PPPM = 1500 W, but larger DO-214AB package (2.5 mm height) and no AEC-Q101 qualification | Requires PCB layout change; lacks automotive qualification and may fail qualification testing | Choose 1.5SMC16A only for non-automotive industrial applications needing higher surge margin |
Compared with SMAJ16A and 1.5SMC16A, TA6F16AHM3_A/H uniquely combines AEC-Q101 qualification, 185 °C operation, and SlimSMA footprint - making it the only drop-in option for space-constrained, high-reliability automotive signal-line protection without redesign.

FAQ
What is the clamping voltage of TA6F16AHM3_A/H at its rated peak pulse current?
The TA6F16AHM3_A/H has a maximum clamping voltage (VC) of 26.7 V when subjected to its rated peak pulse current (IPPM) of 5.0 A under a 10/1000 μs waveform. This value ensures that downstream components like 3.3 V or 5 V microcontrollers remain within safe operating limits during transient events. The TA6F16AHM3_A/H achieves this clamping performance while maintaining low leakage (<1.0 μA at 13.6 V) and high-temperature stability up to 185 °C.
Is TA6F16AHM3_A/H qualified for automotive applications?
Yes, TA6F16AHM3_A/H is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling. It is designed for automotive use cases such as sensor protection, ECU I/O hardening, and BCM signal line safeguarding. The TA6F16AHM3_A/H also meets MSL Level 1 and supports lead-free reflow up to 260 °C, aligning with automotive manufacturing standards.
What package does TA6F16AHM3_A/H use, and what are its key mechanical features?
TA6F16AHM3_A/H uses the SlimSMA (DO-221AC) package - a low-profile surface-mount outline measuring 0.163–0.171 inches in length, 0.098–0.106 inches in width, and 0.035–0.047 inches in height (typical 0.95 mm). It features matte tin-plated terminals, halogen-free molding compound compliant with UL 94 V-0, and a cathode identification band. The TA6F16AHM3_A/H is optimized for automated placement and high-reliability solder joints per J-STD-002 and JESD22-B102.
How does TA6F16AHM3_A/H compare to standard SMAJ series TVS diodes?
Compared to SMAJ16A, TA6F16AHM3_A/H offers higher junction temperature capability (185 °C vs. 150 °C), identical VBR tolerance, and AEC-Q101 qualification - making it suitable for under-hood automotive applications where SMAJ16A would require thermal derating. The TA6F16AHM3_A/H also uses passivated anisotropic rectifier technology for improved long-term reliability under repetitive surge stress, unlike conventional junction-terminated SMAJ devices.
What is the ESD rating of TA6F16AHM3_A/H, and which standard does it meet?
TA6F16AHM3_A/H provides ESD protection up to ±30 kV per IEC 61000-4-2, covering both contact and air discharge test methods. This rating is verified per the manufacturer's qualification report and applies across the full operating temperature range. The TA6F16AHM3_A/H achieves this performance using junction passivation optimized design, eliminating the need for supplemental ESD components in automotive sensor and interface circuits.
