Product details
Overview
TA6L24AHM3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SlimSMAW (DO-221AD) package, designed for high-reliability automotive and industrial electronics protection. It features 24.0 V nominal breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 18.1 A peak pulse current (IPPM), and 33.2 V maximum clamping voltage (VC) - deployed to safeguard MOSFETs and sensor signal lines against inductive switching transients.
For engineers reviewing the TA6L24AHM3/I datasheet, TA6L24AHM3/I pinout, TA6L24AHM3/I application, or TA6L24AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, TJ = 185 °C junction capability, unidirectional configuration, SlimSMAW mechanical compatibility, and 1.0 µA reverse leakage at VWM - all critical for under-hood automotive ECUs and high-temperature industrial control modules.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for stable clamping performance across -65 °C to +185 °C operating range. Its unidirectional structure enables precise overvoltage clamping on positive-going transients while maintaining low leakage (<1.0 µA at VWM) and tight VBR tolerance (±5% at 24.0 V).
The device is rated for 600 W peak pulse power under standardized 10/1000 µs waveform, delivering 33.2 V clamping at 18.1 A IPPM, with thermal resistance RθJA ≤ 150 °C/W on FR4 PCB - enabling robust surge immunity without thermal runaway in compact SMT layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5AT | Same VBR (24.0 V), but lower PPPM (400 W), higher VC (38.9 V), and SMA (DO-214AC) package | Larger footprint and lower surge rating limit use to non-automotive consumer or white goods | Select when cost sensitivity outweighs AEC-Q101 and high-temperature requirements |
| 1.5SMC24AHE3/A | Same VBR, but SMC (DO-214AB) package, 1500 W rating, and no AEC-Q101 qualification | Higher power handling but lacks automotive qualification and has larger board area requirement | Choose for industrial power supplies where footprint and qualification are secondary to surge capacity |
Compared with SMAJ24A-E3/5AT and 1.5SMC24AHE3/A, TA6L24AHM3/I delivers superior thermal robustness (TJ = 185 °C), tighter VC (33.2 V vs. ≥38.9 V), and verified AEC-Q101 compliance - making it the preferred choice for space-constrained, high-reliability automotive signal-line protection.

FAQ
What is the clamping voltage of TA6L24AHM3/I at its rated peak pulse current?
The TA6L24AHM3/I has a maximum clamping voltage (VC) of 33.2 V when subjected to its rated peak pulse current (IPPM) of 18.1 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees the protected circuit will not experience voltages exceeding 33.2 V during a full-rated transient event. The TA6L24AHM3/I maintains this clamping performance across its full operating temperature range.
Is TA6L24AHM3/I qualified for automotive applications?
Yes, TA6L24AHM3/I is AEC-Q101 qualified and meets JESD201 Class 2 whisker test requirements. Its construction uses halogen-free, RoHS-compliant materials and is rated for continuous operation up to +185 °C junction temperature - satisfying critical automotive reliability standards for engine control, HVAC, and body electronics. The HM3 suffix explicitly denotes this qualification status for the TA6L24AHM3/I part number.
What package type does TA6L24AHM3/I use, and how does it compare to SMA or SMC?
TA6L24AHM3/I uses the SlimSMAW (DO-221AD) package - a low-profile variant with 2.70 mm width and 1.10 mm height, significantly smaller than SMA (DO-214AC) and SMC (DO-214AB). This enables higher board density and better thermal performance per unit area. Unlike SMA/SMC, SlimSMAW is MSL Level 1 rated for lead-free reflow up to 260 °C without pre-baking - a key advantage for TA6L24AHM3/I in high-volume automotive manufacturing.
What is the reverse leakage current specification for TA6L24AHM3/I at its stand-off voltage?
At its stand-off voltage (VWM) of 20.5 V and ambient temperature of 25 °C, TA6L24AHM3/I exhibits a maximum reverse leakage current (IR) of 1.0 µA. At elevated temperature (TJ = 150 °C), the leakage remains ≤5.0 µA - confirming stable performance in high-temperature environments. This low leakage preserves signal integrity in precision sensor interfaces and ensures minimal power loss in always-on automotive circuits using TA6L24AHM3/I.
How does the temperature coefficient of breakdown voltage affect TA6L24AHM3/I in wide-temperature designs?
The TA6L24AHM3/I has a typical temperature coefficient of VBR (αT) of 0.085 %/°C, meaning its breakdown voltage increases linearly with junction temperature. For example, at TJ = 125 °C, VBR rises to approximately 25.0 V. This predictable drift allows designers to maintain safe margin above system rail voltage across the full -65 °C to +185 °C range - a critical feature for TA6L24AHM3/I in under-hood automotive applications.
