Product details
Overview
5KP26HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on DC power rails and signal lines. It features 5000 W peak pulse power (10/1000 μs), 26 V stand-off voltage (VWM), 42.1 V maximum clamping voltage at 119 A peak pulse current (IPPM), and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP26HE3/54 datasheet, 5KP26HE3/54 pinout, 5KP26HE3/54 application, or 5KP26HE3/54 equivalent, this device is selected for robust overvoltage protection in switching power supply outputs, motor drive circuits, and automotive ECU power inputs where fast response (<1 ns), low clamping ratio, and high IFSM (600 A) are critical.
Technical Context
The 5KP26HE3/54 operates as a silicon avalanche diode with glass-passivated P600 junction, enabling precise breakdown at 28.9–31.9 V (VBR) under 5 mA test current. Its unidirectional polarity and 0.057 %/°C VBR temperature coefficient ensure stable clamping across -55 °C to +175 °C operating range.
It delivers 5000 W peak pulse power with 10/1000 μs waveform at 0.01 % duty cycle, supported by low incremental surge resistance and sub-1 ns response time. The device is rated for 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C and withstands 600 A 8.3 ms half-sine surge current.
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 |
|---|---|---|---|
| SMBJ26A-E3/52 | Lower peak power (600 W), SMC package, same VWM (26 V), higher VC (42.5 V). | Not suitable for IEC 61000-4-5 Level 4; limited to board-level ESD and low-energy transients. | Select when space-constrained PCB layout requires surface-mount and surge energy is ≤600 W. |
| 1.5KE27A | Same P600 package, 1500 W peak power, VWM = 23.1 V, VC = 37.5 V at 40 A. | Inadequate for 24 V systems exposed to load dump; clamping occurs earlier but handles less energy. | Choose only for cost-sensitive non-automotive applications with verified <1500 W threat profiles. |
Compared with SMBJ26A-E3/52 and 1.5KE27A, the 5KP26HE3/54 delivers 3.3× and 3.3× higher peak pulse power respectively, enabling reliable protection in high-energy automotive and industrial environments where sustained 5 kW surges must be absorbed without failure.

FAQ
What is the clamping voltage of the 5KP26HE3/54 under peak surge conditions?
The 5KP26HE3/54 has a maximum clamping voltage (VC) of 42.1 V at its rated peak pulse current (IPPM) of 119 A using a 10/1000 μs waveform. This value is measured per JEDEC standards and guarantees that protected circuitry sees no more than 42.1 V during worst-case transient events, making it suitable for safeguarding 36 V-rated components downstream of the 5KP26HE3/54.
Is the 5KP26HE3/54 suitable for automotive applications?
Yes, the 5KP26HE3/54 is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body control modules, and infotainment power supplies. Its P600 package, 175 °C max junction temperature, and robust 5000 W surge capability meet ISO 7637-2 load dump requirements, and the HE3 suffix confirms automotive-grade whisker testing per JESD 201 Class 2.
How does the 5KP26HE3/54 differ from the standard 5KP26A-E3/54 variant?
The 5KP26HE3/54 differs from 5KP26A-E3/54 in qualification level and process control: the "H" prefix denotes AEC-Q101 qualification, while the standard E3 version is commercial grade. Both share identical electrical specs (VWM, VBR, VC, PPPM), but the HE3 variant undergoes additional stress testing-including temperature cycling, highly accelerated life testing (HALT), and whisker resistance-to ensure reliability in automotive under-hood environments.
What is the maximum operating temperature for the 5KP26HE3/54?
The 5KP26HE3/54 has an operating junction and storage temperature range of -55 °C to +175 °C. This wide range supports deployment in harsh environments such as automotive engine compartments and industrial motor control cabinets. Derating curves in the datasheet (Fig. 2) define allowable pulse power reduction above 25 °C ambient, ensuring safe operation up to the absolute maximum TJ.
Can the 5KP26HE3/54 be used in bidirectional configurations?
No, the 5KP26HE3/54 is unidirectional only, as confirmed in the Vishay datasheet features section. It conducts in reverse bias during overvoltage events and blocks forward current up to 3.5 V at 100 A. For bidirectional protection, two 5KP26HE3/54 devices must be connected in series opposition, or a dedicated bidirectional TVS such as 5KP26CA should be selected instead.
