Product details
Overview
TA6L16AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SlimSMAW (DO-221AD) 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 185 °C maximum junction temperature - designed for automotive-grade overvoltage protection of MOSFETs and sensor signal lines.
For engineers reviewing the TA6L16AHM3/H datasheet, TA6L16AHM3/H pinout, TA6L16AHM3/H application, or TA6L16AHM3/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal derating behavior, clamping performance at rated surge current, and direct-fit SlimSMAW package compatibility for high-reliability automotive PCB layouts.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable clamping under repetitive transients while maintaining low leakage (<1 µA at VWM) and tight VBR tolerance (±5% at 1 mA). Its unidirectional configuration enables precise reverse-biased protection of DC rails without forward conduction interference.
The device operates across -65 °C to +185 °C junction temperature range and exhibits a positive temperature coefficient of VBR (0.078 %/°C), enabling predictable voltage shift under thermal stress - critical for engine bay and ADAS sensor interface designs where ambient temperatures exceed 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - ensures reliable triggering above system operating voltage while avoiding false trips during normal ripple. |
| VWM | 13.6 V - defines maximum continuous reverse bias before significant leakage onset; matches 12 V automotive supply with margin. |
| IPPM | 26.7 A (10/1000 µs) - delivers robust surge handling for ISO 7637-2 Pulse 1/2a/5a events without degradation. |
| VC @ IPPM | 22.5 V - clamping voltage limits protected IC stress to safe levels during worst-case load dump or inductive kick. |
| TJ max | +185 °C - supports placement near high-power components or under-hood locations without thermal derating penalties. |
| Package | SlimSMAW (DO-221AD) - low-profile (0.90 mm height), MSL Level 1, halogen-free, RoHS-compliant, AEC-Q101 qualified. |
Pinout & Package
SlimSMAW (DO-221AD) is a two-terminal surface-mount package with cathode indicated by a color band. Anode and cathode terminals are located on opposite ends of the molded body, optimized for high-current surge path routing and minimal parasitic inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference plane; carries full IPPM during clamping event. |
| Cathode | Protected line connection point | Connected to line being protected (e.g., sensor VCC or signal); polarity must match unidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use per JESD22-A108 and JESD22-A114; HM3 suffix meets JESD201 Class 2 whisker test. |
| Junction passivation | Optimized die surface treatment prevents moisture-induced degradation and improves long-term reliability in humid environments. |
| MSL Level 1 rating | Compatible with standard SMT reflow profiles up to 260 °C peak, eliminating pre-bake requirements and reducing assembly cost. |
| Low-profile form factor | Height ≤ 0.90 mm enables use in space-constrained modules such as radar front-ends and compact ECU housings. |
Applications
| Automotive Power Rail Protection | Engine Control Unit (ECU) Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V power inputs in body control modules against ISO 7637-2 load dump and jump-start surges. IC Role / Device Role / Timing Role: Unidirectional TVS clamps transient energy to ground before it reaches downstream regulators and microcontrollers. Use Value: Limits rail voltage to ≤22.5 V during 26.7 A surge, preventing latch-up or permanent damage to 3.3 V/5 V logic supplies. | Use Scenario: Safeguarding analog sensor signal lines (e.g., oxygen, knock, MAP sensors) from inductive switching noise in engine compartments. IC Role / Device Role / Timing Role: Fast-response transient suppressor placed adjacent to connector entry points to shunt ESD and switching spikes. Use Value: Clamps sub-100 ns transients below 22.5 V while maintaining <1 µA leakage at 13.6 V, preserving signal integrity and ADC accuracy. |
| ADAS Camera Module Power Input | Electric Power Steering (EPS) Motor Driver Protection |
Use Scenario: Securing 5 V or 12 V camera module inputs exposed to ignition transients and RF coupling in surround-view systems. IC Role / Device Role / Timing Role: Primary overvoltage clamp on power rail, coordinated with upstream fuse and downstream LDO. Use Value: Withstands repeated 600 W pulses and operates reliably up to +185 °C junction temperature near image sensor heat sources. | Use Scenario: Shielding gate drivers and current-sense amplifiers in EPS motor control boards from MOSFET switching-induced voltage spikes. IC Role / Device Role / Timing Role: Localized TVS at driver IC supply pins to absorb fast-rising dv/dt events from H-bridge commutation. Use Value: Low clamping voltage (22.5 V) prevents overvoltage lockout in 16 V-rated gate drivers while supporting AEC-Q101 compliance for safety-critical steering functions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/5AT | Same VBR (16.0 V typ), but lower PPPM (400 W), higher VC (25.8 V), and no AEC-Q101 qualification. | Not suitable for automotive under-hood use; limited to industrial or consumer-grade protection where thermal and reliability margins are relaxed. | Select SMAJ16A-E3/5AT only if cost sensitivity outweighs automotive qualification and clamping performance requirements. |
| 1.5SMC16A | Higher package profile (DO-214AB), same VBR, but lower IPPM (23.5 A) and VC (25.0 V); not AEC-Q101 qualified. | Requires larger PCB footprint and lacks automotive reliability validation; better suited for non-automotive power supply inputs. | Choose 1.5SMC16A only when SlimSMAW height constraint is not applicable and AEC-Q101 is not mandated. |
Compared with SMAJ16A-E3/5AT and 1.5SMC16A, TA6L16AHM3/H provides superior surge capability (600 W vs. ≤400 W), tighter clamping (22.5 V vs. ≥25.0 V), and certified automotive qualification - making it the preferred choice for space-constrained, high-temperature, safety-critical vehicle subsystems.

FAQ
What is the exact breakdown voltage range for TA6L16AHM3/H?
The TA6L16AHM3/H 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 triggering behavior across production lots and temperature extremes, critical for repeatable protection in automotive power systems.
Is TA6L16AHM3/H qualified for automotive applications?
Yes, TA6L16AHM3/H is AEC-Q101 qualified and meets JESD201 Class 2 whisker test requirements. The HM3 suffix explicitly denotes halogen-free, RoHS-compliant construction and automotive qualification - validated for operation from -65 °C to +185 °C junction temperature, making it suitable for under-hood and safety-critical vehicle subsystems.
What is the clamping voltage of TA6L16AHM3/H at its rated surge current?
The TA6L16AHM3/H clamps to a maximum of 22.5 V at its rated peak pulse current (IPPM) of 26.7 A under the standard 10/1000 µs waveform. This low clamping voltage protects downstream 16 V-rated ICs and ensures safe operation even during severe load-dump events defined in ISO 7637-2.
Does TA6L16AHM3/H have a unidirectional or bidirectional configuration?
TA6L16AHM3/H is a unidirectional TVS diode, meaning it conducts only in reverse bias to clamp positive transients on a DC line referenced to ground. It must be installed with cathode toward the protected line and anode to ground - incorrect polarity will prevent proper protection and may cause catastrophic failure during surge events.
What package type does TA6L16AHM3/H use, and what are its key mechanical features?
TA6L16AHM3/H uses the SlimSMAW (DO-221AD) package: a low-profile surface-mount case measuring ≤0.90 mm in height, with matte tin-plated leads solderable per J-STD-002, UL 94 V-0 molding compound, and MSL Level 1 rating for lead-free reflow up to 260 °C - ideal for dense automotive PCB layouts requiring high reliability and minimal Z-height.
