For engineers reviewing the 5KP7.5A-E3/54 datasheet, 5KP7.5A-E3/54 pinout, 5KP7.5A-E3/54 application, or 5KP7.5A-E3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, P600 mechanical dimensions, clamping performance under 10/1000 μs transients, and RoHS-compliant commercial-grade sourcing details - all specific to the exact orderable part 5KP7.5A-E3/54.
Technical Context
The 5KP7.5A-E3/54 operates as a unidirectional avalanche diode with glass-passivated P600 junction, optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its 5000 W peak pulse rating is defined per JEDEC-standard 10/1000 μs waveform at 0.01% duty cycle, with thermal derating above 25 °C per Fig. 2 of document 88308.
It exhibits 250 μA maximum reverse leakage at 7.5 V (VWM), 3.5 V forward voltage at 100 A, and a positive temperature coefficient of VBR (+0.073 %/°C), enabling stable clamping across -55 °C to +175 °C operating range. The device is rated for 600 A non-repetitive surge (8.3 ms half-sine) and meets JESD 22-B106 solderability requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5A | Lower peak power (600 W), smaller SMB package, same VWM/VBR tolerance | Not suitable for IEC 61000-4-5 Level 4; limited to board-level ESD and low-energy switching noise | Select SMBJ7.5A only for space-constrained consumer electronics where 5000 W capability is unnecessary. |
| 5KP7.5CA | Bi-directional variant; identical P600 package and 5000 W rating but symmetric clamping | Required for AC-coupled or bidirectional signal lines (e.g., RS-485, CAN bus); not interchangeable with unidirectional 5KP7.5A-E3/54 | Choose 5KP7.5CA only when protecting balanced differential buses; 5KP7.5A-E3/54 remains optimal for DC power rails. |
Compared with SMBJ7.5A and 5KP7.5CA, the 5KP7.5A-E3/54 uniquely delivers automotive-grade unidirectional 5000 W surge immunity in P600 form factor - making it irreplaceable for high-energy DC rail protection where bi-directionality is unnecessary and compactness is secondary to robustness.

FAQ
What is the clamping voltage of the 5KP7.5A-E3/54 under maximum surge conditions?
The 5KP7.5A-E3/54 clamps to a maximum of 12.9 V when subjected to its rated peak pulse current of 388 A (10/1000 μs waveform). This value is measured per JEDEC test conditions and represents the worst-case voltage seen by downstream components during a full 5000 W transient event - critical for validating IC survivability in designs using this TVS.
Is the 5KP7.5A-E3/54 qualified for automotive applications?
Yes, the 5KP7.5A-E3/54 is AEC-Q101 qualified, as confirmed in Vishay document 88308. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and surge robustness - making the 5KP7.5A-E3/54 suitable for under-hood and chassis-mounted automotive modules including body control units and power distribution centers.
What does the "E3/54" suffix mean in 5KP7.5A-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred packaging code - 13-inch paper tape and reel containing 800 units. This exact ordering configuration ensures compatibility with automated SMT placement systems and matches Vishay's standard logistics for the 5KP7.5A-E3/54.
Can the 5KP7.5A-E3/54 replace a 5KP7.5AHE3/54 in an automotive design?
No - the 5KP7.5AHE3/54 carries the "HE3" suffix denoting AEC-Q101 qualification, whereas the 5KP7.5A-E3/54 is commercial grade (base E3). While both share identical electrical specs and P600 package, only the HE3 version is certified for automotive use; substituting 5KP7.5A-E3/54 in AEC-Q101-mandated applications violates qualification requirements and voids compliance.
What is the maximum operating temperature for the 5KP7.5A-E3/54?
The 5KP7.5A-E3/54 has a specified operating junction temperature range of -55 °C to +175 °C. This allows direct mounting on high-temperature PCB areas near power converters or in engine bay enclosures without derating, provided thermal design accounts for its 8.0 W steady-state power dissipation at TL = 75 °C per Figure 5 of document 88308.
