Product details
Overview
TA6L16AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SlimSMAW (DO-221AD) package, designed for automotive-grade overvoltage protection. It features 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 26.7 V maximum clamping voltage at 5.0 A IPPM, and 185 °C maximum junction temperature - enabling robust protection of MOSFETs and sensor signal lines in engine control units.
For engineers reviewing the TA6L16AHM3/I datasheet, TA6L16AHM3/I pinout, TA6L16AHM3/I application, or TA6L16AHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, SlimSMAW mechanical dimensions, and direct alternatives for automotive electronics design and ESD/surge hardening.
Technical Context
This TVS diode operates as a unidirectional clamping device with passivated anisotropic rectifier technology, optimized for high-reliability automotive environments. Its junction passivation and 185 °C TJ rating support operation under under-hood thermal stress, while MSL Level 1 and JESD 201 Class 2 whisker compliance ensure assembly robustness.
The device delivers precise voltage thresholding via tightly controlled VBR (15.2–16.8 V) and low leakage (<1.0 µA at VWM), enabling stable protection without loading sensitive signal paths. Its 26.7 V clamping voltage at 5.0 A ensures predictable energy diversion during ISO 7637-2 or IEC 61000-4-5 transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - defines precise turn-on threshold for transient suppression |
| VWM | 13.6 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 26.7 V at 5.0 A - clamping voltage limiting downstream component stress during surge |
| PPPM | 600 W (10/1000 µs) - peak surge energy handling capability per standard waveform |
| TJ max | +185 °C - enables placement near high-temperature sources like powertrain ECUs |
| Package | SlimSMAW (DO-221AD) - low-profile, AEC-Q101 qualified surface-mount outline with cathode band marking |
| Qualification | AEC-Q101 qualified, JESD 201 Class 2 whisker tested - certified for automotive production use |
Pinout & Package
SlimSMAW (DO-221AD) is a two-terminal surface-mount package with cathode identified by a color band on the top surface. The device has no internal circuitry beyond the single silicon junction; terminals are anode and cathode only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected line's ground or low-side reference in unidirectional clamp configuration |
| Cathode | Current exit point during forward conduction; marked by color band | Connected to protected IC/MOSFET input or signal line - clamps transients toward ground when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Enables precise overvoltage protection on DC-biased signal or power rails without affecting normal forward operation |
| 185 °C junction temperature rating | Supports reliable operation in under-hood automotive locations where ambient temperatures exceed 125 °C |
| AEC-Q101 qualification + JESD 201 Class 2 | Validates long-term reliability for automotive production, including resistance to tin whisker growth in matte tin terminations |
| Low leakage & tight VBR tolerance | ≤1.0 µA IR at VWM and ±5% VBR window minimize standby power loss and improve system-level voltage margin control |
| SlimSMAW (DO-221AD) footprint | 0.197" × 0.106" body with 0.055" minimum pad spacing - enables high-density PCB layout while maintaining creepage/clearance |
Applications
| Engine Control Unit (ECU) Power Input Protection | Automotive Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V supply rail of engine control modules against load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery rail and input filter capacitor to clamp surges above 16 V. Use Value: 26.7 V clamping voltage limits stress on downstream LDOs and microcontrollers; 600 W rating handles ISO 7637-2 Pulse 5a events. | Use Scenario: Safeguarding analog outputs of pressure or temperature sensors connected to CAN or LIN buses. IC Role / Device Role / Timing Role: Single-ended TVS on sensor output line referenced to chassis ground, suppressing ESD and inductive switching noise. Use Value: 13.6 V stand-off allows full sensor dynamic range; <1.0 µA leakage prevents signal offset drift at 25 °C and 150 °C. |
| Body Control Module (BCM) Switched Load Interface | Electric Power Steering (EPS) Motor Driver Protection |
Use Scenario: Protecting high-side driver outputs controlling solenoids, relays, or lamps in BCMs exposed to inductive kickback. IC Role / Device Role / Timing Role: TVS placed across inductive load to absorb flyback energy during MOSFET turn-off. Use Value: 185 °C TJ rating ensures survival during sustained high-current switching cycles; 16.0 V VBR aligns with 12 V system logic thresholds. | Use Scenario: Clamping gate-source voltage spikes on EPS motor driver MOSFETs caused by fast dv/dt switching and parasitic inductance. IC Role / Device Role / Timing Role: TVS connected between gate and source terminals to limit VGS excursion during Miller plateau transitions. Use Value: Low capacitance (typ. 150 pF at 0 V) avoids slowing gate drive; unidirectional structure prevents interference with normal gate biasing. |
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-E3/5AT (Vishay) | Same VBR (16.0 V typ.), but SMA (DO-214AC) package; RθJA = 140 °C/W vs. 120 °C/W for TA6L16AHM3/I | Higher thermal resistance limits power dissipation in compact layouts; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and thermal performance requirements |
| TPSMD16A (Texas Instruments) | Identical VBR, VWM, and VC; DO-214AB (SMC) package; AEC-Q101 qualified; RθJA = 130 °C/W | Larger footprint (7.11 × 6.22 mm vs. 5.00 × 2.70 mm) may constrain layout in space-constrained modules | Choose when higher surge current rating (IPPM = 32.4 A) is required, accepting larger board area |
Compared with SMAJ16A-E3/5AT and TPSMD16A, TA6L16AHM3/I offers superior thermal performance (120 °C/W RθJA) and smallest footprint among AEC-Q101-qualified 16 V TVS diodes, making it optimal for high-density automotive control units where thermal headroom and board space are critical.

FAQ
What is the exact breakdown voltage range for TA6L16AHM3/I?
The TA6L16AHM3/I has a guaranteed breakdown voltage (VBR) range of 15.2 V (minimum) to 16.8 V (maximum) at 1.0 mA test current, with 16.0 V as the nominal value. This tight ±5% tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in automotive control systems.
Is TA6L16AHM3/I qualified for automotive applications?
Yes, TA6L16AHM3/I is AEC-Q101 qualified and meets JESD 201 Class 2 whisker testing requirements. Its SlimSMAW package uses matte tin-plated leads and is rated for operation up to +185 °C junction temperature, satisfying automotive under-hood reliability standards for engine control, transmission, and chassis modules.
What is the maximum clamping voltage of TA6L16AHM3/I and at what current?
The maximum clamping voltage (VC) of TA6L16AHM3/I is 26.7 V at a peak pulse current (IPPM) of 5.0 A, measured using the standardized 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
Does TA6L16AHM3/I have bidirectional or unidirectional polarity?
TA6L16AHM3/I is strictly unidirectional. Its cathode is marked by a visible color band on the package top surface, and it conducts only when the cathode is biased positive relative to the anode - making it suitable for DC-biased power and signal line protection, not AC or differential bus applications.
What package type does TA6L16AHM3/I use and what are its key mechanical features?
TA6L16AHM3/I uses the SlimSMAW (DO-221AD) package: a low-profile surface-mount outline measuring 5.00 mm × 2.70 mm with 0.055 mm minimum pad spacing. It features UL 94 V-0 molding compound, matte tin-plated leads compliant with J-STD-002, and MSL Level 1 moisture sensitivity for lead-free reflow up to 260 °C.
