Overview
5KP26A-E3/54 from Vishay General Semiconductor is a unidirectional 5000 W transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features a 26.0 V stand-off voltage (VWM), 28.9–31.9 V breakdown voltage (VBR) at 5.0 mA, clamps to ≤42.1 V at 119 A peak pulse current (10/1000 μs), and operates from –55 °C to +175 °C. It is widely used in automotive power supply inputs and industrial motor drive control circuits.
For engineers reviewing the 5KP26A-E3/54 datasheet, 5KP26A-E3/54 pinout, 5KP26A-E3/54 application, or 5KP26A-E3/54 equivalent, key selection criteria include clamping voltage under 119 A surge, unidirectional polarity confirmation, P600 mechanical compatibility, AEC-Q101 qualification status, and thermal derating above 25 °C ambient.
Technical Context
This TVS diode uses a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance. Its 5000 W peak pulse power rating (10/1000 μs) supports robust protection against lightning-induced transients and inductive switching spikes in 12 V–48 V systems.
The device exhibits a temperature coefficient of VBR of +0.101 %/°C and maintains stable clamping performance up to 175 °C junction temperature. It is rated for 500 A non-repetitive forward surge current (8.3 ms half-sine) and dissipates 8.0 W on an infinite heatsink at TL = 75 °C.
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 |
|---|---|---|---|
| Littelfuse SMAJ26A | Lower PPPM (400 W), SMA package (0.5 W PD), 26.0 V VWM, same unidirectional polarity | Suitable for low-energy board-level ESD only; not rated for automotive load dump or lightning | Select 5KP26A-E3/54 when >1 kV/100 A surge immunity is required; SMAJ26A fits space-constrained layouts but lacks P600 thermal mass. |
| ON Semiconductor 1.5KE27A | Same P600 package, 27 V VWM, 5000 W PPPM, but higher VC (45.7 V at 109 A) and no AEC-Q101 qualification | Acceptable for industrial AC/DC supplies; not validated for automotive temperature cycling or humidity testing | Choose 5KP26A-E3/54 for automotive-grade reliability and tighter clamping; 1.5KE27A offers cost advantage where qualification is not mandated. |

FAQ
What is the clamping voltage of the 5KP26A-E3/54 under a 10/1000 μs surge?
The 5KP26A-E3/54 clamps to a maximum of 42.1 V when subjected to its rated peak pulse current of 119 A (10/1000 μs waveform). This value is measured per JEDEC standards and represents the highest voltage imposed on the protected circuit during worst-case transient events. The 5KP26A-E3/54 achieves this clamping performance while maintaining low incremental surge resistance, ensuring consistent protection across multiple surge events.
Is the 5KP26A-E3/54 suitable for automotive applications?
Yes, the 5KP26A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive under-hood environments. Its –55 °C to +175 °C operating junction temperature range, resistance to thermal cycling, and validation against humidity and mechanical shock make it appropriate for use in engine control units, body control modules, and ADAS power supplies. The 5KP26A-E3/54 meets ISO 16750-2 load dump requirements when properly mounted with adequate copper area.
What does the "E3/54" suffix mean in 5KP26A-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance. The "/54" denotes the preferred packaging code: 13-inch diameter paper tape and reel, with a base quantity of 800 units per reel. This packaging format is optimized for automated SMT placement and ensures moisture-sensitive handling per J-STD-020. The 5KP26A-E3/54 ordering code guarantees full traceability and compliance documentation from Vishay.
How does the 5KP26A-E3/54 compare to bidirectional TVS diodes?
The 5KP26A-E3/54 is unidirectional and protects only against positive-going transients on the cathode-connected line. Unlike bidirectional variants, it provides lower leakage current (<2 μA at 26 V) and avoids forward conduction during normal negative excursions. This makes the 5KP26A-E3/54 ideal for DC power rail protection where polarity is fixed, whereas bidirectional types are reserved for AC lines or data buses with symmetrical voltage swings.
What thermal considerations apply when using the 5KP26A-E3/54 in high-temperature environments?
The 5KP26A-E3/54 must be derated above 25 °C ambient per Figure 2 in the datasheet: power dissipation drops linearly to zero at 175 °C junction temperature. For sustained operation at 100 °C ambient, PCB copper area ≥250 mm² per lead and thermal vias are recommended. The 5KP26A-E3/54's 175 °C TJ max enables placement near heat sources, but thermal simulation is advised for continuous surge duty cycles exceeding 0.01%.
