Product details
Overview
TA6L10AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) in SlimSMAW (DO-221AD) package, designed for automotive-grade overvoltage protection of signal lines and MOSFET gates. It features 10.0 V nominal breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 41.4 V maximum clamping voltage at 14.5 A peak pulse current, 600 W peak pulse power (10/1000 µs), and 185 °C maximum junction temperature - enabling robust protection in engine control units and sensor interfaces.
For engineers reviewing the TA6L10AHM3/I datasheet, TA6L10AHM3/I pinout, TA6L10AHM3/I application, or TA6L10AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional configuration, SlimSMAW thermal performance (RθJA = 120–150 °C/W), low leakage (<5.0 µA at VWM), and compatibility with high-reliability automotive PCB layouts requiring MSL Level 1 and JESD22-B102 solderability.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and surge immunity. Its unidirectional architecture provides precise reverse-biased clamping during transients, with breakdown voltage tightly controlled (9.5–10.5 V at 1.0 mA test current) and temperature coefficient of +0.064 %/°C ensuring predictable VBR drift across -65 to +185 °C operating range.
The device delivers 600 W peak pulse power under standardized 10/1000 µs waveform conditions, clamping to ≤41.4 V at 14.5 A IPPM. Its SlimSMAW (DO-221AD) package supports high-current surge handling while maintaining low profile and JEDEC-compliant thermal resistance to ambient (120–150 °C/W) and mount (12–15 °C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 / 10.0 / 10.5 V at 1.0 mA - defines precise clamping onset threshold for reliable overvoltage detection |
| VWM | 8.55 V - maximum continuous reverse voltage before significant leakage begins |
| IPPM | 14.5 A (10/1000 µs) - peak surge current it safely diverts without failure |
| VC | 41.4 V at IPPM - clamped voltage seen by protected circuit during worst-case transient |
| TJ max | +185 °C - enables operation in under-hood automotive environments without derating |
| Package | SlimSMAW (DO-221AD) - low-profile, AEC-Q101 qualified, MSL Level 1, 260 °C reflow compatible |
| Polarity | Unidirectional - cathode-band marked; protects against negative-going transients only |
Pinout & Package
SlimSMAW (DO-221AD) is a two-terminal surface-mount package with cathode band marking on one end. Terminals are matte tin-plated for J-STD-002/JESD22-B102 solderability. Mounting pad layout follows JEDEC DO-221AD standard with 0.173–0.197 inch body length and 0.035–0.043 inch width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or common return path; forms clamping path during reverse surge |
| Cathode | Protected line input | Connected to signal/MOSFET gate; voltage above VWM triggers avalanche conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress-test requirements including temperature cycling, HTRB, and ESD |
| Junction temperature rating | 185 °C maximum - eliminates derating in high-ambient under-hood applications |
| Clamping ratio (VC/VBR) | 4.14 - ensures low overvoltage margin during 14.5 A surges, protecting sensitive IC inputs |
| Leakage current | <5.0 µA at VWM - minimizes standby power loss and avoids false triggering in low-power sensor circuits |
| Thermal resistance RθJM | 12–15 °C/W - enables efficient heat transfer to PCB copper, sustaining repeated surge events |
Applications
| Automotive Engine Control Unit (ECU) | Automotive Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting microcontroller GPIOs and driver outputs from load-dump and inductive switching transients in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between MCU pin and harness connector to clamp negative-going spikes below absolute maximum ratings.

IC Role / Device Role / Timing Role: Low-capacitance TVS connected inline with sensor signal trace to shunt fast transients before reaching ADC input stage. Use Value: Clamps 14.5 A surges to ≤41.4 V within nanoseconds, preserving signal integrity and meeting AEC-Q200 Class D ESD immunity requirements. |
| Automotive Power MOSFET Gate Protection | Industrial CAN Transceiver Interface |
Use Scenario: Shielding high-side/low-side MOSFET gates from Miller-induced voltage overshoot and gate-drive ringback in motor drivers. IC Role / Device Role / Timing Role: TVS placed directly across gate-source terminals to limit VGS excursion during switching transitions. Use Value: Withstands repetitive 600 W pulses and operates up to 185 °C, ensuring long-term reliability in thermally constrained gate-drive PCB areas. | Use Scenario: Adding secondary overvoltage protection on CAN_H/CAN_L lines downstream of primary bus transceivers in chassis networks. IC Role / Device Role / Timing Role: Unidirectional TVS on each CAN line referenced to ground, absorbing residual transients that bypass main protection. Use Value: Provides 41.4 V clamping at 14.5 A with minimal parasitic capacitance, avoiding CAN bit timing distortion while meeting ISO 11898-2 EMC limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VBR (10.0 V), but lower PPPM (400 W), higher VC (16.7 V), and SMA (DO-214AC) package with higher RθJA (~160 °C/W) | Limited to non-automotive industrial use due to lack of AEC-Q101 qualification and lower surge margin | Select when cost sensitivity outweighs automotive qualification and thermal performance needs |
| TPSMD10A | Same VBR (10.0 V), identical PPPM (600 W), but SOD-128 package and slightly higher VC (42.1 V); also AEC-Q101 qualified | Compatible footprint but requires layout adjustment; same thermal capability (RθJM ~13 °C/W) | Choose if existing design uses SOD-128 land pattern and requires drop-in replacement with verified automotive compliance |
Compared with SMAJ10A and TPSMD10A, TA6L10AHM3/I offers superior thermal management via SlimSMAW's lower RθJA, tighter VBR tolerance (±5%), and halogen-free HM3 suffix - making it optimal for space-constrained, high-reliability automotive modules where junction temperature control and long-term stability are critical.

FAQ
What is the exact breakdown voltage specification for TA6L10AHM3/I?
The TA6L10AHM3/I has a guaranteed breakdown voltage (VBR) range of 9.5 V (minimum) to 10.5 V (maximum) at 1.0 mA test current, with 10.0 V nominal value. This tight ±5% tolerance ensures predictable clamping behavior in automotive signal protection circuits where precise voltage thresholds are required to avoid false triggering or insufficient protection.
Is TA6L10AHM3/I qualified for automotive applications?
Yes, TA6L10AHM3/I is AEC-Q101 qualified and meets JESD201 Class 2 whisker test requirements. Its SlimSMAW package, 185 °C maximum junction temperature rating, and halogen-free HM3 suffix confirm suitability for automotive powertrain, body control, and ADAS modules where long-term reliability under thermal and mechanical stress is mandatory.
What does the "HM3" suffix indicate in TA6L10AHM3/I?
The "HM3" suffix in TA6L10AHM3/I denotes halogen-free construction, RoHS compliance, AEC-Q101 qualification, and packaging in 13-inch tape-and-reel format (14,000 units per reel). It distinguishes this variant from non-automotive versions and confirms adherence to automotive material and process standards including JESD22-B102 solderability.
How does TA6L10AHM3/I compare to standard SMAJ10A in surge handling?
TA6L10AHM3/I delivers 600 W peak pulse power (10/1000 µs) with 41.4 V clamping at 14.5 A, whereas SMAJ10A provides only 400 W and clamps at 16.7 V. The TA6L10AHM3/I also features lower thermal resistance (120–150 °C/W vs. ~160 °C/W), enabling better sustained surge performance in compact automotive PCB layouts.
What is the polarity configuration of TA6L10AHM3/I?
TA6L10AHM3/I is unidirectional - it conducts only during reverse-biased overvoltage events. The cathode is marked by a color band; the anode connects to ground or system return, and the cathode connects to the protected line. This configuration is ideal for protecting against negative-going transients on DC-biased signal paths such as sensor outputs or MOSFET gates.
