Product details
Overview
5KP26-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal paths. It features a 26 V standoff voltage (VWM), 28.9–31.9 V breakdown voltage (VBR) at 5.0 mA, 42.1 V clamping voltage (VC) at 119 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 µs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients and lightning surges.
For engineers reviewing the 5KP26-E3/54 datasheet, 5KP26-E3/54 pinout, 5KP26-E3/54 application, or 5KP26-E3/54 equivalent, this device is evaluated for robust overvoltage clamping in automotive power supplies, industrial motor drives, telecom DC feeds, and AEC-Q101-qualified embedded systems requiring stable thermal derating up to 175 °C junction temperature and low incremental surge resistance.
Technical Context
This TVS diode uses a P600 glass-passivated chip junction optimized for fast response (<1 ns) and low dynamic impedance under high-current transients. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
The device operates within -55 °C to +175 °C junction temperature range and supports 8.0 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature. It meets JESD 22-B106 soldering requirements (275 °C, 10 s) and JESD 201 Class 1A whisker testing (E3 suffix).

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 peak power (400 W), SMA package (surface-mount), 26 V VWM, 42.1 V VC at 9.5 A. | Designed for PCB space-constrained consumer electronics; lacks AEC-Q101 and P600 thermal mass for high-energy surges. | Select when board area is critical and surge energy remains below 400 W; not suitable for automotive load dump. |
| ON Semiconductor 1.5KE27A | Same P600 package, 27 V VWM, 45.7 V VC at 109 A, 1500 W rating (10/1000 µs), no AEC-Q101 qualification. | General-purpose industrial use; lower clamping ratio but insufficient for ISO 7637-2 Pulse 5 compliance. | Use where cost sensitivity outweighs automotive qualification and 5000 W requirement; verify thermal design for repeated surges. |

FAQ
What is the clamping voltage of the 5KP26-E3/54 under maximum surge conditions?
The 5KP26-E3/54 exhibits a maximum clamping voltage (VC) of 42.1 V when subjected to its rated peak pulse current of 119 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The 5KP26-E3/54 maintains this clamping performance across its full operating temperature range, ensuring consistent protection behavior in automotive and industrial environments.
Is the 5KP26-E3/54 qualified for automotive applications?
Yes, the 5KP26-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT). This qualification confirms its suitability for automotive powertrain, body control, and infotainment modules where reliability under thermal and electrical stress is mandatory. The 5KP26-E3/54 meets these requirements as part of the Vishay 5KP family certified to AEC-Q101 Rev D.
What does the "E3/54" suffix indicate in 5KP26-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker-resistant matte tin plating. The "/54" indicates the preferred package code for 13-inch paper tape and reel delivery, with a base quantity of 800 units per reel. This ordering format ensures standardized logistics and automated assembly compatibility for the 5KP26-E3/54 in high-volume manufacturing environments.
How does the 5KP26-E3/54 compare to standard 1.5 kW TVS diodes like 1.5KE26A?
The 5KP26-E3/54 delivers over three times the peak pulse power (5000 W vs. 1500 W) and higher surge current capacity (119 A vs. ~65 A) compared to 1.5KE26A, while sharing the same P600 package outline. Its lower clamping ratio (42.1 V / 28.9 V ≈ 1.46 vs. ~1.55) and AEC-Q101 qualification make the 5KP26-E3/54 appropriate for demanding automotive load-dump protection where the 1.5KE26A would fail or require parallel staging.
Can the 5KP26-E3/54 be used in bidirectional configurations?
No, the 5KP26-E3/54 is unidirectional only, as confirmed in the Vishay datasheet. It conducts in forward bias and clamps in reverse bias above VBR; it does not provide symmetrical protection for AC or bipolar signal lines. For bidirectional transient suppression, a separate device such as the 5KP26CA (center-tapped, bidirectional variant) must be selected - the 5KP26-E3/54 is strictly for DC-biased applications with defined polarity.
