Product details
Overview
6KA24HE3_A/C from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in P600 package, designed for automotive load dump protection. It features 24 V working stand-off voltage (VWM), 26.7–32.6 V breakdown voltage (VBR), 6000 W peak pulse power (10/1000 μs), 185 °C maximum junction temperature, and AEC-Q101 qualification.
For engineers reviewing the 6KA24HE3_A/C datasheet, 6KA24HE3_A/C pinout, 6KA24HE3_A/C application, or 6KA24HE3_A/C equivalent, key selection criteria include clamping voltage at 90 A (40 V @ 25 °C), low leakage (1.0 μA @ 24 V), surge robustness (400 A IFSM), and high-temperature reliability up to 185 °C in under-hood automotive environments.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable clamping performance across -65 °C to +185 °C. Its unidirectional polarity and 24 V VWM make it suitable for DC supply rail protection where reverse conduction must be blocked.
The device delivers 6000 W peak pulse power with 10/1000 μs waveform and 2000 W with 10 μs/50 ms waveform, supporting both fast transients and longer-duration surges. Clamping voltage remains ≤45 V at 90 A and 150 °C, ensuring sustained protection during high-temperature operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24AHE3_A/H | Lower PPPM (600 W vs. 6000 W); SMB package (smaller footprint, lower thermal mass) | Suitable for PCB-level point-of-load protection, not main battery rail | Select when space-constrained and surge energy is limited to <100 mJ |
| 1.5KE24A | Higher VBR tolerance (26.7–32.6 V same), but no AEC-Q101 qualification; DO-201 package | Acceptable for non-automotive industrial use only | Choose only for cost-sensitive legacy designs without automotive qualification requirements |
Compared with SMBJ24AHE3_A/H and 1.5KE24A, the 6KA24HE3_A/C delivers tenfold higher surge power handling and certified automotive reliability, making it the sole option for primary 24 V load dump protection in modern commercial vehicle ECUs.

FAQ
What is the clamping voltage of the 6KA24HE3_A/C at 90 A?
The 6KA24HE3_A/C has a maximum clamping voltage (VC) of 40 V at 90 A peak pulse current and 25 °C ambient temperature. At 150 °C junction temperature, VC rises to 45 V, reflecting its specified thermal stability across the full AEC-Q101 operating range. This value is measured using the 10/1000 μs waveform per IEC 61000-4-5 and is critical for ensuring downstream ICs remain within safe operating voltage limits during load dump events.
Is the 6KA24HE3_A/C qualified for automotive applications?
Yes, the 6KA24HE3_A/C is AEC-Q101 qualified and explicitly designed for automotive use. It meets the stress test requirements for temperature cycling, humidity, mechanical shock, and high-temperature operating life. Its 185 °C maximum junction temperature and P600 package with matte tin leads support under-hood placement in engine control units, battery management systems, and body electronics where thermal and environmental robustness are mandatory.
What does the "HE3" suffix indicate in 6KA24HE3_A/C?
The "HE3" suffix in 6KA24HE3_A/C denotes Vishay's high-reliability packaging standard: RoHS-compliant construction, AEC-Q101 qualification, and compliance with JESD201 Class 2 whisker resistance. The "A/C" revision code identifies the specific manufacturing lot and process iteration, ensuring traceability and consistent parametric performance across production batches.
How does the 6KA24HE3_A/C differ from standard 24 V TVS diodes like SMBJ24A?
The 6KA24HE3_A/C differs from SMBJ24A primarily in surge power rating (6000 W vs. 600 W), package thermal capacity (P600 vs. SMB), and qualification level (AEC-Q101 vs. commercial grade). Its larger P600 case enables higher energy dissipation and superior heat spreading, while the 185 °C TJ rating supports sustained operation in high-ambient environments where SMBJ24A would thermally saturate or fail prematurely.
What is the maximum DC reverse leakage current for the 6KA24HE3_A/C?
The maximum DC reverse leakage current (IR) for the 6KA24HE3_A/C is 1.0 μA at 24 V reverse bias and 25 °C ambient temperature. At elevated temperature (150 °C), leakage increases to 50 μA-still well within acceptable limits for battery-powered automotive modules. This low leakage directly contributes to extended system standby time and reduced parasitic drain in always-on vehicle networks.
