Product details
Overview
5KP15-E3/54 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), 15.0 V stand-off voltage (VWM), 24.4 V maximum clamping voltage (VC) at 205 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the 5KP15-E3/54 datasheet, 5KP15-E3/54 pinout, 5KP15-E3/54 application, or 5KP15-E3/54 equivalent, this device is selected for robust overvoltage protection in switching power supply outputs, automotive ECUs, industrial motor drives, and sensor interface circuits where fast response (<1 ns), low clamping ratio, and high surge current handling are critical.
Technical Context
The 5KP15-E3/54 operates as a silicon avalanche diode with glass-passivated P600 junction, optimized for unidirectional clamping of positive-going transients relative to ground. Its breakdown voltage (VBR) is specified at 16.7–18.5 V (50 mA test current), ensuring tight tolerance control around the 15 V nominal stand-off level.
It delivers 5000 W peak pulse power under standardized 10/1000 μs waveform conditions with 0.01% duty cycle, and exhibits low incremental surge resistance enabling stable clamping performance across repetitive surge events. Thermal derating begins above 25 °C ambient, with maximum junction temperature rated at +175 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.0 V - Maximum continuous reverse operating voltage before conduction; defines safe DC bias margin for 12 V nominal systems. |
| VBR (min/max) | 16.7 V / 18.5 V - Breakdown voltage range at 50 mA; ensures predictable turn-on threshold with ±5% tolerance. |
| VC @ IPPM | 24.4 V - Clamped voltage at 205 A peak pulse current; limits downstream voltage stress during surge events. |
| PPPM | 5000 W - Peak pulse power rating (10/1000 μs); supports high-energy lightning-induced or inductive-switching transients. |
| IPPM | 205 A - Peak pulse current capability; enables protection against severe surges without catastrophic failure. |
| TJ max | +175 °C - Maximum junction temperature; allows operation in under-hood automotive or high-ambient industrial environments. |
| Polarity | Unidirectional - Cathode-banded configuration; protects against positive transients only; requires correct orientation in circuit. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; RoHS-compliant (E3 suffix), UL 94 V-0 rated, 2.776 g unit weight, supplied in 13" paper tape and reel (800 pcs per reel, code 54).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to system ground or return path; completes clamping loop during transient event. |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V rail); color band identifies cathode end for correct PCB placement. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics use including engine control units and body modules under harsh thermal and vibration conditions. |
| 5000 W peak pulse power | Enables single-device protection against IEC 61000-4-5 Level 4 (4 kV/2 Ω) surges without external series impedance. |
| Clamping ratio (VC/VWM) | 1.63 - Low ratio ensures minimal overvoltage exposure to downstream ICs during clamping, preserving MOSFET gate integrity. |
| Fast response time | <1 ns - Avalanche conduction initiates rapidly upon overvoltage, limiting transient energy delivered to protected circuitry. |
| P600 package thermal mass | Supports 8.0 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature, aiding thermal recovery after surge. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive DC Bus |

Use Value: 2.0 μA max leakage at 15 V preserves signal integrity in precision 4–20 mA loops and ratiometric ADC interfaces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Lower peak power (600 W), SMC package, 24.4 V clamping at 24.2 A (not 205 A) | Suitable for board-level ESD protection, not high-energy load dump or lightning surges | Select when space-constrained layouts require SMC footprint and surge energy is ≤100 J. |
| 1.5KE15A | Same P600 package, but lower peak power (1500 W), 24.4 V clamping at 61.5 A | Limited to medium-energy transients; insufficient for automotive load dump compliance | Choose only for cost-sensitive non-automotive applications where 5000 W rating is unnecessary. |
Compared with SMBJ15A and 1.5KE15A, the 5KP15-E3/54 provides 3.3× and 3.3× higher peak pulse power respectively, enabling compliance with ISO 7637-2 Pulse 5a and IEC 61000-4-5 Ed.3 requirements-critical for automotive and industrial power electronics where single-point robustness is mandatory.

FAQ
What is the clamping voltage of the 5KP15-E3/54 under maximum surge conditions?
The 5KP15-E3/54 has a maximum clamping voltage (VC) of 24.4 V when subjected to its rated peak pulse current of 205 A (10/1000 μs waveform). This value is measured per JEDEC standards and guarantees consistent overvoltage limiting behavior across production lots and temperature ranges from −55 °C to +175 °C.
Is the 5KP15-E3/54 suitable for automotive applications?
Yes, the 5KP15-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and infotainment power supplies. Its P600 package, 175 °C junction rating, and robust surge handling make it appropriate for under-hood and cabin environments subject to load dump and ISO 7637-2 transients.
Does the 5KP15-E3/54 have bidirectional polarity?
No, the 5KP15-E3/54 is unidirectional only. Its cathode is marked by a color band, and it conducts only during positive transients relative to ground. For bidirectional protection, two devices must be used in series opposition or a dedicated bidirectional TVS such as 5KP15CA should be selected instead.
What is the maximum steady-state power dissipation for the 5KP15-E3/54?
The 5KP15-E3/54 has a maximum steady-state power dissipation (PD) of 8.0 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C. This rating applies to continuous DC or low-duty-cycle operation-not to transient surge conditions-and must be thermally managed via PCB copper area or external heatsinking.
How does the 5KP15-E3/54 compare to standard 1.5KE series TVS diodes?
The 5KP15-E3/54 delivers 5000 W peak pulse power-more than three times the 1500 W rating of the 1.5KE15A-while sharing the same P600 package. Its higher IPPM (205 A vs. 61.5 A) and superior thermal robustness make it suitable for applications where 1.5KE devices would fail catastrophically under repeated high-energy surges.
