Product details
Overview
5KP58A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection. It features 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 5 mA, 94 V maximum clamping voltage (VC) at 53.4 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 5KP58A-E3/54 datasheet, 5KP58A-E3/54 pinout, 5KP58A-E3/54 application, or 5KP58A-E3/54 equivalent, key selection criteria include clamping performance under 53.4 A surge, thermal derating above 25 °C, unidirectional polarity confirmation via cathode band, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped crowbar element during transients, leveraging a glass-passivated P600 chip junction for low incremental surge resistance and sub-nanosecond response. Its 94 V clamping voltage at 53.4 A ensures robust overvoltage limiting for 48 V nominal systems, while the 175 °C max junction temperature supports operation in high-ambient environments.
The device is rated for 500 A non-repetitive forward surge current (IFSM) and dissipates up to 8.0 W on an infinite heatsink at 75 °C. Its 0.107 %/°C VBR temperature coefficient enables stable breakdown behavior across automotive temperature ranges, and the matte tin-plated leads comply with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58.0 V - Maximum continuous reverse operating voltage before clamping begins; defines system working voltage margin. |
| VBR (min/max) | 64.4 V / 71.2 V at 5 mA - Confirmed breakdown range ensuring reliable turn-on without premature conduction. |
| VC @ IPPM | 94 V at 53.4 A - Clamping voltage under full-rated 10/1000 μs surge; determines protected circuit's peak stress level. |
| PPPM | 5000 W - Peak pulse power handling capability; enables survival of lightning-induced or inductive-switching transients. |
| TJ max. | +175 °C - Maximum junction temperature; allows use in under-hood automotive and industrial power supply environments. |
| Polarity | Unidirectional - Cathode-band marked; suitable for DC-biased rail protection only, not AC line applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-E3/52 | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range, no AEC-Q101 qualification. | Suitable for space-constrained consumer or industrial boards where 5000 W surge capacity is unnecessary. | Select when board-level layout limits P600 footprint and peak surge energy is <100 mJ. |
| 5KP58CA-E3/54 | Same package and ratings but bidirectional; adds symmetric clamping for AC-coupled or floating signal lines. | Required for differential bus protection (e.g., CAN, RS-485) where reverse polarity transients occur. | Choose only if bidirectional clamping is mandated; otherwise 5KP58A-E3/54 offers lower capacitance and cost. |
Compared with SMBJ58A-E3/52 and 5KP58CA-E3/54, the 5KP58A-E3/54 delivers industry-leading 5000 W surge capacity in a through-hole P600 package with automotive-grade AEC-Q101 validation - making it optimal for high-reliability DC rail protection where physical mounting stability and thermal mass matter.

FAQ
What is the clamping voltage of the 5KP58A-E3/54 under maximum rated surge current?
The 5KP58A-E3/54 has a maximum clamping voltage (VC) of 94 V when subjected to its rated peak pulse current (IPPM) of 53.4 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting for downstream components in 48 V systems. The 5KP58A-E3/54 maintains this clamping performance across its specified operating temperature range.
Is the 5KP58A-E3/54 suitable for automotive applications?
Yes, the 5KP58A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive electronic modules including body control units, ADAS power supplies, and infotainment systems. Its 175 °C maximum junction temperature, robust P600 package, and validated surge performance meet stringent automotive reliability requirements. The 5KP58A-E3/54 is explicitly listed in Vishay's AEC-Q101 qualified product matrix.
What does the "-E3/54" suffix indicate in 5KP58A-E3/54?
The "-E3" denotes RoHS-compliant, commercial-grade packaging with JESD201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery with a base quantity of 800 units. This ordering code ensures traceable, standardized logistics and surface-mount compatible taping - critical for automated assembly of the 5KP58A-E3/54 in high-volume production.
How does the 5KP58A-E3/54 differ from bidirectional TVS diodes like 5KP58CA-E3/54?
The 5KP58A-E3/54 is unidirectional and protects only positive-going transients on a DC-biased line, whereas the 5KP58CA-E3/54 provides symmetrical clamping for both polarities - essential for AC signals or floating buses. The 5KP58A-E3/54 exhibits lower junction capacitance and avoids reverse conduction leakage in DC applications, making it preferable for 48 V rail protection where polarity is fixed.
Can the 5KP58A-E3/54 replace older 5KP58A parts without design changes?
Yes, the 5KP58A-E3/54 is a direct form-fit-function replacement for legacy 5KP58A variants in P600 package, maintaining identical electrical specifications, mechanical dimensions, and thermal characteristics. Its RoHS-compliant matte tin plating and JESD201 Class 1A whisker resistance ensure compatibility with modern assembly processes - no PCB or schematic modifications are needed when upgrading to the 5KP58A-E3/54.
