Product details
Overview
5KP7.0A-E3/51 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 7.0 V stand-off voltage (VWM), 7.78–8.60 V breakdown voltage (VBR) at 50 mA, 5000 W peak pulse power (10/1000 µs), and clamps to ≤12.0 V at 417 A peak pulse current. It is widely deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the 5KP7.0A-E3/51 datasheet, 5KP7.0A-E3/51 pinout, 5KP7.0A-E3/51 application, or 5KP7.0A-E3/51 equivalent, this device is evaluated for high-energy surge immunity in 12 V automotive systems, DC-DC converter output protection, and ESD-hardened I/O line guarding where fast response (<1 ns), low clamping ratio, and AEC-Q101 qualification are required.
Technical Context
The 5KP7.0A-E3/51 operates as a silicon avalanche diode with glass-passivated P600 package construction, enabling robust handling of repetitive 10/1000 µs transients up to 5000 W at 0.01% duty cycle. Its unidirectional polarity and cathode-band marking simplify PCB layout and orientation verification during assembly.
It exhibits a 0.068 %/°C temperature coefficient of VBR, ensuring stable breakdown across –55 °C to +175 °C junction temperature range, and maintains <2000 µA reverse leakage at 7.0 V, supporting low-quiescent-power system designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system operating margin for 12 V nominal rails. |
| VBR @ IT = 50 mA | 7.78–8.60 V - Confirmed avalanche onset range; ensures reliable triggering above normal rail noise but below IC absolute maximum ratings. |
| VC @ IPPM = 417 A | ≤12.0 V - Clamped voltage under full 5000 W surge; limits downstream component stress to safe levels during ISO 7637-2 Pulse 5a events. |
| IPPM | 417 A - Peak pulse current capability with 10/1000 µs waveform; supports protection against high-current load dump transients. |
| PPPM | 5000 W - Peak pulse power rating; enables single-device suppression of severe automotive and industrial surges without cascaded stages. |
| TJ max. | +175 °C - Maximum junction temperature; allows operation in under-hood environments and high-ambient industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including HTOL, TC, and HAST; suitable for safety-critical power rail protection. |
Pinout & Package
Package: P600 molded epoxy case with matte tin-plated leads; RoHS-compliant, UL 94 V-0 rated; cathode indicated by color band. Lead finish meets J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes conduction path during reverse-biased surge event. |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., battery feed); avalanche conduction initiates here when VWM exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 µs) | Enables single-device protection against severe ISO 7637-2 Load Dump and IEC 61000-4-5 Level 4 surges without derating or parallel devices. |
| Clamping voltage ≤12.0 V at 417 A | Provides >30% headroom below typical 16 V automotive IC absolute maximum ratings, reducing risk of latch-up or permanent damage. |
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity testing, and long-term high-temperature operation per JEDEC standards. |
| 0.068 %/°C VBR tempco | Ensures predictable breakdown shift over temperature-critical for maintaining protection margins in wide-ambient applications like engine control units. |
| Uni-directional polarity only | Simplifies design for DC-biased rails; eliminates need for series blocking diodes or dual TVS configurations in unidirectional systems. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Guarding |

Use Value: Withstands repetitive 5000 W pulses at 0.01% duty cycle, enabling reliable protection without thermal runaway or degradation. |
Use Scenario: Protecting PoE-powered network switches from lightning-induced surges on 48 V DC feeder lines (IEC 61000-4-5). IC Role / Device Role / Timing Role: First-stage shunt protector mounted at DC input connector before upstream filtering and regulation. Use Value: 5000 W rating and 417 A IPPM meet Class B/C surge requirements while maintaining low capacitance (<100 pF) to avoid signal distortion. |
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 SMAJ7.0A | Lower peak power (400 W), smaller SMA package (vs. P600), higher VC/VBR ratio (1.7× vs. 1.4×), non-AEC-Q101. | Suitable for space-constrained consumer electronics; insufficient for automotive load dump or industrial 5000 W surges. | Select 5KP7.0A-E3/51 when 5000 W surge handling, AEC-Q101 compliance, or high-temperature stability (>125 °C) is required. |
| ON Semiconductor 1.5KE7.0A | Same P600 package, lower peak power (1500 W), higher VC (12.5 V), no AEC-Q101 qualification, higher leakage (5000 µA). | Acceptable for basic industrial power rail protection where surge severity is moderate and qualification is not mandated. | Choose 5KP7.0A-E3/51 for automotive or mission-critical applications demanding verified 5000 W capability and extended temperature reliability. |
Compared with SMAJ7.0A and 1.5KE7.0A, the 5KP7.0A-E3/51 delivers 3.3× and 3.3× higher peak power respectively, AEC-Q101 validation for automotive deployment, and tighter VBR tolerance-making it the only option among the three qualified for ISO 16750-2 load dump compliance.

FAQ
What is the clamping voltage of the 5KP7.0A-E3/51 under maximum surge conditions?
The 5KP7.0A-E3/51 clamps to a maximum of 12.0 V when subjected to its rated peak pulse current of 417 A (10/1000 µs waveform). This value is guaranteed per Vishay's datasheet Table on page 2 and reflects worst-case device behavior at TA = 25 °C. The clamping performance remains stable across temperature due to its low 0.068 %/°C VBR temperature coefficient.
Is the 5KP7.0A-E3/51 suitable for automotive applications?
Yes, the 5KP7.0A-E3/51 is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and infotainment power supplies. Its 175 °C maximum junction temperature, robust P600 package, and validated performance under ISO 7637-2 Pulse 5a make it appropriate for under-hood and chassis-mounted deployments.
What does the "E3/51" suffix indicate in 5KP7.0A-E3/51?
The "E3" denotes RoHS-compliant, commercial-grade termination per JESD 201 Class 1A whisker test; "/51" specifies the packaging variant-51 indicates 800-piece tape-and-reel delivery in 13″ diameter reels. This matches Vishay's ordering information table on page 3 of document 88308.
How does the 5KP7.0A-E3/51 differ from the 5KP7.0CA variant?
The 5KP7.0A-E3/51 is unidirectional, while the 5KP7.0CA is bidirectional. The "A" suffix indicates unidirectional polarity (cathode-banded), suitable for DC-biased rails; the "CA" version provides symmetrical clamping for AC or floating signal lines. They share identical VWM, VBR, and PPPM, but differ in polarity configuration and circuit placement requirements.
What is the maximum reverse leakage current for the 5KP7.0A-E3/51 at rated stand-off voltage?
At VWM = 7.0 V and TA = 25 °C, the 5KP7.0A-E3/51 exhibits a maximum reverse leakage current (ID) of 1000 µA, as specified in the Electrical Characteristics table on page 2 of Vishay document 88308. This low leakage supports efficient operation in always-on automotive modules with strict quiescent current budgets.
