Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower PPPM (600 W), smaller SMB package (3.5 mm x 3.5 mm), VC = 103 V @ 5.8 A | Suitable for space-constrained consumer PCBs but insufficient for automotive load dump compliance | Select when board area is critical and surge energy is limited to ≤600 W |
| 1.5KE68CAHE3_B | Same electrical specs and AEC-Q101 qualification; differs only in revision code ("B" vs "A/C") per Vishay ordering nomenclature | No functional or application difference; identical mounting, thermal, and reliability behavior | Use interchangeably where "B" revision is stocked; verify latest date code for production release alignment |
Compared with SMBJ64CA and 1.5KE68CAHE3_B, the 1.5KE68CAHE3_A/C provides higher surge robustness (1500 W vs 600 W) in a through-hole package ideal for high-reliability industrial and automotive harness connections, while maintaining full AEC-Q101 compliance and backward compatibility with prior HE3 revisions.

FAQ
What is the breakdown voltage range of the 1.5KE68CAHE3_A/C?
The 1.5KE68CAHE3_A/C has a guaranteed breakdown voltage (VBR) range of 64.6 V to 71.4 V at 1.0 mA test current, measured per JEDEC standard. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes, making it suitable for designs requiring precise overvoltage thresholds in automotive and industrial systems.
Is the 1.5KE68CAHE3_A/C suitable for automotive applications?
Yes, the 1.5KE68CAHE3_A/C is AEC-Q101 qualified and explicitly listed in Vishay's qualified devices for automotive use (Revision 09-Aug-2022, Doc. 88301). Its 175 °C max junction temperature, glass-passivated junction, and UL 497B recognition make it appropriate for engine control units, body electronics, and ADAS sensor interfaces exposed to load dump and ISO 7637-2 pulses.
How does the 1.5KE68CAHE3_A/C differ from unidirectional variants like 1.5KE68AHE3_A/C?
The 1.5KE68CAHE3_A/C is bidirectional, meaning it clamps symmetrically in both polarities with no cathode marking, whereas 1.5KE68AHE3_A/C is unidirectional and requires correct orientation with a band-marked cathode. The bidirectional version supports AC-coupled lines and floating references, while the unidirectional type offers lower leakage in DC-biased applications.
What is the maximum clamping voltage of the 1.5KE68CAHE3_A/C during a surge event?
The 1.5KE68CAHE3_A/C clamps to a maximum of 92.0 V at its rated peak pulse current of 16.3 A (10/1000 µs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry - critical for ensuring downstream ICs remain within absolute maximum ratings during surge events.
Does the 1.5KE68CAHE3_A/C have RoHS and lead-free compliance?
Yes, the "HE3" suffix confirms the 1.5KE68CAHE3_A/C is RoHS-compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and JESD 201 Class 2 whisker resistance. It is also compatible with standard SnPb and lead-free reflow profiles, supporting mixed-technology assembly in industrial and automotive manufacturing.
