Product details
Overview
TA6L10AHM3/H 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 10.0 V nominal breakdown voltage (VBR), 8.55 V maximum stand-off voltage (VWM), 41.4 V 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 of MOSFETs and sensor signal lines in engine control units.
For engineers reviewing the TA6L10AHM3/H datasheet, TA6L10AHM3/H pinout, TA6L10AHM3/H application, or TA6L10AHM3/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 rating, halogen-free RoHS-compliant construction, and compatibility with high-reliability automotive transients induced by inductive load switching.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable clamping performance across -65 °C to +185 °C operating range. Its junction passivation and optimized thermal design support sustained operation under high-temperature automotive conditions without derating loss up to 150 °C ambient.
The device operates as a single-element, cathode-banded unidirectional clamp with low dynamic impedance. It meets JEDEC JESD22-B102 solderability standards and J-STD-020 MSL Level 1 reflow profile (260 °C peak), ensuring compatibility with standard SMT assembly processes for automotive PCBs.

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 VWM (8.55 V) and VC (41.4 V), but rated for 400 W PPPM and not AEC-Q101 qualified | Limited to industrial/commercial use; lacks automotive qualification and 185 °C TJ rating | Select SMAJ10A only for non-automotive designs where cost sensitivity outweighs reliability requirements |
| TPSMF10A | Identical 10 V VBR, 41.4 V VC, and 600 W rating, but in SOD-128 package (slightly larger footprint) | Compatible with same PCB layout with minor pad adjustment; shares AEC-Q101 and 185 °C ratings | Choose TPSMF10A when existing SOD-128 land pattern is fixed and SlimSMAW rework is impractical |
Compared with SMAJ10A and TPSMF10A, TA6L10AHM3/H uniquely combines AEC-Q101 qualification, 185 °C junction rating, and ultra-low 1.10 mm profile in DO-221AD - making it optimal for next-generation compact, high-temperature automotive modules requiring zero compromise on reliability or form factor.

FAQ
What is the maximum clamping voltage of the TA6L10AHM3/H under standard test conditions?
The TA6L10AHM3/H has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current of 14.5 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuits during surge events. The TA6L10AHM3/H maintains this clamping performance across its full operating temperature range due to its low VBR temperature coefficient of 0.064 %/°C.
Is the TA6L10AHM3/H qualified for automotive applications?
Yes, the TA6L10AHM3/H is AEC-Q101 qualified and meets JESD201 Class 2 whisker test requirements. Its HM3 suffix denotes halogen-free, RoHS-compliant construction and full automotive qualification. The TA6L10AHM3/H is rated for continuous operation up to +185 °C junction temperature, making it suitable for under-hood and powertrain applications where thermal stress is extreme.
What package type does the TA6L10AHM3/H use, and what are its key mechanical attributes?
The TA6L10AHM3/H uses the SlimSMAW (DO-221AD) surface-mount package: 4.00 mm × 2.70 mm × 1.10 mm with matte tin-plated leads. It meets UL 94 V-0 flammability rating, supports MSL Level 1 handling (260 °C peak reflow), and features a cathode identification band. The TA6L10AHM3/H's low profile enables high-density routing in space-constrained automotive PCBs without compromising thermal or electrical performance.
How does the TA6L10AHM3/H compare to standard SMAJ-series TVS diodes in terms of reliability?
The TA6L10AHM3/H exceeds standard SMAJ-series diodes in high-temperature reliability: it supports 185 °C maximum junction temperature versus 150 °C for most SMAJ parts, and carries full AEC-Q101 qualification - unlike generic SMAJ10A. The TA6L10AHM3/H also features junction passivation optimized for automotive life-cycle stress, whereas SMAJ devices target commercial/industrial use. Both share similar VBR and VC, but TA6L10AHM3/H delivers superior long-term stability in thermally aggressive environments.
What is the leakage current specification for the TA6L10AHM3/H at its maximum working voltage?
At its maximum stand-off voltage (VWM) of 8.55 V and ambient temperature of 25 °C, the TA6L10AHM3/H exhibits a maximum reverse leakage current (IR) of 5.0 µA. At elevated temperature (TJ = 150 °C), leakage increases to 20 µA - still well below thresholds that would impact battery-sensitive automotive modules. This low leakage ensures minimal power loss in always-on vehicle subsystems where the TA6L10AHM3/H is deployed.
