Product details
Overview
5KP90A-E3/51 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge clamping in power supply outputs and automotive electronics. It features 90 V stand-off voltage (VWM), 100–111 V breakdown voltage (VBR) at 5 mA, 146 V maximum clamping voltage (VC) at 34.2 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs waveform).
For engineers reviewing the 5KP90A-E3/51 datasheet, 5KP90A-E3/51 pinout, 5KP90A-E3/51 application, or 5KP90A-E3/51 equivalent, key selection criteria include clamping performance under 10/1000 μs surges, unidirectional polarity for DC rail protection, AEC-Q101 qualification for automotive use, thermal derating above 25 °C, and compatibility with P600 PCB footprint and lead-free soldering (J-STD-002, JESD 22-B102).
Technical Context
This TVS diode operates as a voltage-clamping overvoltage protection device on DC power rails, triggered when reverse voltage exceeds its breakdown threshold. Its glass-passivated P600 junction delivers low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of transients induced by inductive load switching or lightning surges.
The 5KP90A-E3/51 is rated for 5000 W peak pulse power (10/1000 μs), 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, and withstands 600 A non-repetitive forward surge current (8.3 ms half-sine). Junction temperature range is –55 °C to +175 °C, with ±5 % VBR tolerance and 0.110 %/°C temperature coefficient.
Key Specifications

Use Value: Low clamping voltage and fast response complement upstream GDTs to meet <100 V let-through requirement for PoE interface ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90A | Lower peak power (600 W), smaller SMB package, same 90 V VWM and unidirectional polarity. | Not suitable for ISO 7637-2 load dump; limited to board-level ESD and low-energy transients. | Select SMBJ90A only for space-constrained consumer or computing applications where 5000 W surge immunity is not required. |
| 1.5KE91A | Same VWM (91 V), lower PPPM (1500 W), DO-201 package, no AEC-Q101 qualification. | Lacks automotive qualification and thermal robustness for under-hood deployment. | Choose 1.5KE91A for cost-sensitive industrial controls where AEC-Q101 compliance and 5000 W rating are unnecessary. |
Compared with SMBJ90A and 1.5KE91A, the 5KP90A-E3/51 provides 3.3× higher surge power handling and automotive-grade reliability-making it the sole option among the three for protecting 12 V/24 V automotive power nets against load dump and ISO 7637-2 Pulse 5.

FAQ
What is the clamping voltage of the 5KP90A-E3/51 under full-rated surge conditions?
The 5KP90A-E3/51 has a maximum clamping voltage (VC) of 146 V when subjected to its rated peak pulse current of 34.2 A using a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that protected downstream components will not experience reverse voltage exceeding 146 V during worst-case transients. The 5KP90A-E3/51 maintains this clamping performance across its specified junction temperature range.
Is the 5KP90A-E3/51 suitable for automotive applications?
Yes, the 5KP90A-E3/51 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its –55 °C to +175 °C operating junction temperature range, P600 mechanical robustness, and compliance with ISO 7637-2 load dump requirements make it appropriate for engine control units, body control modules, and ADAS power supplies. The 5KP90A-E3/51 meets all stress tests defined in the AEC-Q101 standard for transient voltage suppressors.
What does the "E3/51" suffix indicate in 5KP90A-E3/51?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/51" specifies the preferred packaging code-51 indicates 800 pieces per 13-inch paper tape and reel. This differs from /54 (also 800/reel) and reflects Vishay's internal tape-and-reel configuration coding. The 5KP90A-E3/51 is lead-free and compatible with standard reflow and wave soldering processes.
How does the 5KP90A-E3/51 compare to bidirectional TVS diodes?
The 5KP90A-E3/51 is unidirectional and protects only against reverse-polarity transients on positive rails-unlike bidirectional variants that guard both polarities. Its lower leakage and tighter VBR tolerance improve efficiency in DC applications. For AC or dual-rail systems, a bidirectional part like 5KP90CA would be required; the 5KP90A-E3/51 is optimized for single-polarity DC bus protection where polarity is fixed and clamping precision is critical.
Can the 5KP90A-E3/51 replace a 5KP90AHE3/51 in an automotive design?
No-the 5KP90AHE3/51 is AEC-Q101 qualified, while the 5KP90A-E3/51 is commercial grade (base P/N-E3). Although both share identical electrical specs and P600 packaging, only the HE3 variant carries automotive qualification. Substituting 5KP90A-E3/51 in AEC-Q101–mandated designs violates compliance requirements. Always verify suffix codes: "HE3" = AEC-Q101; "E3" = commercial. The 5KP90A-E3/51 must not be used where automotive qualification is contractually or safety-required.
