Product details
Overview
5KP24-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 24 V stand-off voltage (VWM), 26.7–29.5 V breakdown voltage (VBR) at 5.0 mA, 38.9 V maximum clamping voltage (VC) at 129 A peak pulse current, and 5000 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supplies and industrial motor drives.
For engineers reviewing the 5KP24-E3/54 datasheet, 5KP24-E3/54 pinout, 5KP24-E3/54 application, or 5KP24-E3/54 equivalent, this device is evaluated for overvoltage protection in 24 V systems requiring AEC-Q101 qualification, low clamping ratio, and robust surge handling up to 129 A without degradation under repetitive transients.
Technical Context
This TVS diode uses a P600 glass-passivated junction optimized for fast response (<1 ps) and low incremental surge resistance, enabling precise clamping during lightning-induced or inductive-switching transients. Its unidirectional polarity and 175 °C max junction temperature support operation in under-hood automotive environments and industrial power converters.
The device operates with a 2.0 µA max reverse leakage at 24 V and exhibits a +0.101 %/°C temperature coefficient of VBR, ensuring stable breakdown behavior across thermal gradients. It is rated for 600 A non-repetitive forward surge current (8.3 ms half-sine) and complies with JESD 22-B106 solderability (275 °C, 10 s).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin for 24 V nominal systems. |
| VBR (min/max) | 26.7 V / 29.5 V at 5.0 mA - Confirmed breakdown range ensures reliable turn-on above system overvoltage thresholds. |
| VC @ IPPM | 38.9 V at 129 A - Clamping voltage limits downstream IC stress during 10/1000 µs surges; clamping ratio = 1.62×VWM. |
| PPPM | 5000 W - Peak pulse power handling capability enables protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges. |
| IFSM | 600 A - Non-repetitive forward surge rating supports crowbar-style fault clearing in power supply outputs. |
| TJ max | 175 °C - High junction temperature rating allows placement near heat sources in engine control units and inverters. |
Pinout & Package
5KP24-E3/54 is housed in a P600 axial-leaded package with cathode indicated by a color band. The device has two terminals: anode and cathode - no internal circuitry or additional pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration. |
| Cathode | Clamping terminal | Connected to protected line (e.g., 24 V rail); color band identifies this end for correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control modules and body electronics per stress test requirements. |
| 5000 W peak pulse power | Enables single-device protection against severe transients (e.g., ISO 7637-2 Pulse 5a) without parallel staging. |
| Low clamping ratio (1.62×VWM) | Minimizes voltage overshoot on protected ICs such as CAN transceivers or microcontrollers during surge events. |
| P600 glass passivated junction | Ensures long-term reliability and stable VBR under humidity, thermal cycling, and mechanical vibration. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive DC Bus |
|---|---|

IC Role / Device Role / Timing Role: Placed at main 24 V input connector to divert ESD and relay coil flyback energy away from logic circuitry. Use Value: Withstands >1000 surges at rated power while maintaining <2.0 µA leakage - preserving standby current budget. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Lower peak power (600 W), smaller SMB package, same VWM/VC but higher clamping ratio (43.5 V). | Suitable for space-constrained PCBs with lower surge exposure (e.g., USB-powered devices), not for automotive load dump. | Select when board area is critical and surge threat level is below IEC 61000-4-5 Level 2. |
| 1.5KE24A | Same P600 package, lower peak power (1500 W), higher VC (38.9 V → 43.0 V), no AEC-Q101 qualification. | Acceptable for commercial-grade industrial controls but not certified for automotive deployment. | Choose only if AEC-Q101 compliance is not required and system surge energy is limited to <1500 W. |
Compared with SMBJ24A and 1.5KE24A, the 5KP24-E3/54 delivers 3.3× higher pulse power and automotive qualification - making it the sole option for protecting 24 V systems subject to ISO 7637-2 Pulse 5a or load dump, where sustained clamping performance and reliability under thermal stress are mandatory.

FAQ
What is the clamping voltage of the 5KP24-E3/54 under maximum surge conditions?
The 5KP24-E3/54 clamps to a maximum of 38.9 V when subjected to its rated 129 A peak pulse current (10/1000 µs waveform). This value is measured and guaranteed per JEDEC test conditions and reflects worst-case voltage seen by downstream components during surge events. The 5KP24-E3/54 maintains this clamping performance across its full operating temperature range and after repeated transient exposures.
Is the 5KP24-E3/54 suitable for automotive applications?
Yes, the 5KP24-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units and body electronics. Its 175 °C maximum junction temperature, robust P600 package, and validated performance under load dump (ISO 7637-2 Pulse 5a) make it appropriate for under-hood and chassis-mounted systems. The 5KP24-E3/54 meets all stress tests defined in the AEC-Q101 standard for transient voltage suppressors.
What does the "E3/54" suffix mean in 5KP24-E3/54?
The "E3" denotes RoHS-compliant, commercial-grade termination with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred packaging code - 13-inch paper tape and reel containing 800 units. This ordering format ensures traceable, standardized logistics for automated SMT assembly and inventory control. The 5KP24-E3/54 is supplied in this exact configuration with full Vishay material certification.
How does the 5KP24-E3/54 compare to bidirectional TVS diodes?
The 5KP24-E3/54 is unidirectional and intended for DC line protection where polarity is fixed - it blocks reverse voltage up to 24 V and clamps positive surges only. Bidirectional variants (e.g., 5KP24CA) would conduct in both directions and are used for AC or data-line protection. Using the 5KP24-E3/54 on AC signals risks forward conduction and failure; always match polarity and application topology. The 5KP24-E3/54's unidirectional design yields tighter VBR tolerance and lower leakage than equivalent bidirectional parts.
Can the 5KP24-E3/54 replace a fuse or circuit breaker?
No - the 5KP24-E3/54 is not a replacement for overcurrent protection devices. It functions solely as a voltage-clamping element to limit transient overvoltages, allowing time for upstream fuses or breakers to clear faults. Per Vishay application notes, the 5KP24-E3/54 is designed to work alongside, not instead of, thermal-magnetic protection. Its 600 A IFSM rating supports surviving surge currents long enough for coordinated protection to operate, but it does not interrupt steady-state fault current like a fuse.
