Product details
Overview
6KA24-3HE3_A/C from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in P600 package, rated for 24 V working voltage, 6000 W peak pulse power (10/1000 μs), and 185 °C junction temperature - designed for automotive load dump protection in engine control units and body electronics.
For engineers reviewing the 6KA24-3HE3_A/C datasheet, 6KA24-3HE3_A/C pinout, 6KA24-3HE3_A/C application, or 6KA24-3HE3_A/C equivalent, key selection criteria include clamping voltage at 90 A (40 V max), AEC-Q101 qualification, low leakage (1.0 μA @ 24 V), high surge capability (400 A IFSM), and P600 mechanical robustness for under-hood environments.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to achieve stable breakdown behavior up to TJ = 185 °C, with verified clamping performance across temperature (VC = 45 V max @ 150 °C, IPP = 90 A). Its unidirectional polarity and 26.7–32.6 V breakdown range ensure precise overvoltage triggering during transients.
It meets JESD 22-B106 solder dip requirements (275 °C, 10 s) and JESD 201 Class 2 whisker resistance, supporting reflow and wave soldering in automotive production. The P600 case provides UL 94 V-0 flammability compliance and mechanical ruggedness for high-vibration applications.
Key Specifications

| VBR min/max | 26.7 V / 32.6 V - guaranteed breakdown range at 100 mA test current, defining turn-on threshold |
| PPPM (10×1000 μs) | 6000 W - peak transient energy absorption capability for standard automotive load dump waveform |
| VC @ 90 A | 40 V max @ 25 °C - clamping voltage limiting downstream circuit stress during 90 A surge |
| IRSM | 90 A - peak pulse current rating for 10/1000 μs waveform, used in derating calculations |
| TJ max | 185 °C - extended junction temperature rating enabling placement near heat sources in engine bays |

FAQ
What is the clamping voltage of the 6KA24-3HE3_A/C at 90 A?
The 6KA24-3HE3_A/C has a maximum clamping voltage (VC) of 40 V at 90 A peak pulse current and 25 °C ambient, rising to 45 V at 150 °C. This value is measured using the 10/1000 μs waveform and defines the upper voltage limit imposed on protected circuits during surge events. The 6KA24-3HE3_A/C maintains this clamping performance across its full operating temperature range, ensuring consistent protection in under-hood environments.
Is the 6KA24-3HE3_A/C qualified for automotive applications?
Yes, the 6KA24-3HE3_A/C is AEC-Q101 qualified and explicitly designed for automotive use. It meets stress test requirements including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT). Its 185 °C maximum junction temperature and P600 package construction align with under-hood deployment needs. The 6KA24-3HE3_A/C data sheet confirms qualification status in the Mechanical Data and Additional Characteristics sections.
What does the "HE3" suffix indicate in 6KA24-3HE3_A/C?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads that pass JESD 201 Class 2 whisker testing, and indicates compliance with Vishay's high-reliability manufacturing standards. The "_A/C" revision code specifies the production lot and process version. The 6KA24-3HE3_A/C uses the same die and P600 package as base 6KA24HE3 variants, with identical electrical specifications and qualification status.
Can the 6KA24-3HE3_A/C replace the older 6KA24HE3_B/C?
Yes, the 6KA24-3HE3_A/C is a direct replacement for 6KA24HE3_B/C, sharing identical electrical characteristics, thermal ratings, package dimensions, and AEC-Q101 qualification. The "3" in the part number reflects internal Vishay manufacturing traceability and does not alter performance. Engineers may substitute 6KA24-3HE3_A/C without PCB or schematic changes, and the 6KA24-3HE3_A/C maintains full compatibility with existing test fixtures and assembly processes.
What is the maximum DC reverse leakage current for the 6KA24-3HE3_A/C?
The 6KA24-3HE3_A/C exhibits a maximum DC reverse leakage current (ID) of 1.0 μA at 24 V and 25 °C, increasing to 50 μA at 150 °C. This low leakage ensures minimal standby power draw in always-on vehicle networks and avoids false triggering in high-impedance sensing circuits. The 6KA24-3HE3_A/C maintains these values across its full -65 °C to +185 °C operating range, as verified in the Additional Characteristics table of its datasheet.
