Product details
Overview
5KP7.0AHE3/54 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 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), 417 A peak pulse current (IPPM), and clamps to ≤12.0 V at rated current - deployed in automotive power supply outputs and industrial sensor interfaces.
For engineers reviewing the 5KP7.0AHE3/54 datasheet, 5KP7.0AHE3/54 pinout, 5KP7.0AHE3/54 application, or 5KP7.0AHE3/54 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, P600 mechanical dimensions, clamping performance under 10/1000 μs transients, and direct alternatives for overvoltage protection design-in.
Technical Context
The 5KP7.0AHE3/54 uses a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
Rated for 175 °C maximum junction temperature and qualified to AEC-Q101, it supports repetitive surge events at 0.01 % duty cycle while maintaining stable clamping voltage (VC = 12.0 V) and low leakage (<1000 μA at 7.0 V). The matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 7.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 7.78–8.60 V at 50 mA - Confirmed avalanche onset range; ensures reliable triggering during overvoltage events. |
| PPPM (Peak Pulse Power) | 5000 W (10/1000 μs) - Sustains high-energy transients without failure; enables replacement of crowbar circuits in SMPS outputs. |
| IPPM (Peak Pulse Current) | 417 A - Delivers robust surge handling for ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4 compliance. |
| VC (Clamping Voltage) | ≤12.0 V at IPPM - Limits downstream voltage stress to protect 12 V-rated ICs and MOSFETs during surge conditions. |
| TJ max. | 175 °C - Supports operation in under-hood automotive environments and high-temperature industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard. |
Pinout & Package
Package: P600 molded epoxy case with UL 94 V-0 flammability rating; cathode indicated by color band; lead finish: matte tin; RoHS-compliant and AEC-Q101 qualified (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / surge return node | Connected to system ground or low-side reference; carries full IPPM during clamping event. |
| Cathode | Protected line connection / high-side input | Connected to line being protected (e.g., 12 V rail); blocks reverse current until VBR exceeded. |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against severe load dump and inductive switching surges without derating. |
| Fast response time (<1 ns) | Clamps before sensitive downstream components experience damaging overvoltage stress. |
| P600 glass-passivated junction | Provides stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero-failure field performance. |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes voltage overshoot across protected devices, reducing need for additional series impedance or filtering. |
Applications
| Automotive Power Supply Output | Industrial Sensor Signal Line Protection |
|---|---|
|
Use Scenario: Protecting 12 V output of vehicle alternator regulator or DC-DC converter against load dump transients (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Unidirectional TVS placed between output rail and chassis ground to clamp surges up to 120 V peak. Use Value: Prevents latch-up or destruction of downstream CAN transceivers and microcontrollers by limiting rail voltage to ≤12.0 V during 417 A transient events. |
Use Scenario: Safeguarding analog output of pressure or temperature sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: TVS connected across sensor output and ground to absorb ESD (IEC 61000-4-2) and burst noise (IEC 61000-4-4). Use Value: Maintains signal integrity by suppressing transients before they distort 4–20 mA or 0–10 V analog signals, avoiding false readings or controller resets. |
| Switching Power Supply Crowbar Replacement | Telecom DC Feeder Line Protection |
|
Use Scenario: Replacing SCR-based crowbar circuits in 48 V telecom rectifiers to avoid permanent short-circuit shutdown after overvoltage. IC Role / Device Role / Timing Role: Self-resetting TVS that clamps and recovers automatically, allowing system reset without fuse replacement. Use Value: Reduces maintenance downtime and eliminates need for manual intervention after transient events - critical for remote base station uptime. |
Use Scenario: Protecting PoE-powered equipment (e.g., IP cameras) from lightning-induced surges on 48 V DC feeder lines. IC Role / Device Role / Timing Role: Primary-level TVS mounted at DC input connector to divert >5 kV/500 A surges per IEC 61000-4-5. Use Value: Ensures survivability of IEEE 802.3af/at PD circuitry by limiting voltage seen by DC-DC controller to safe levels (≤12.0 V) during surge decay. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0AHE3/52 | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range, AEC-Q101 qualified. | Suitable for space-constrained PCBs with lower surge energy requirements (e.g., USB ports, low-power sensors). | Select when board area is limited and peak surge current ≤60 A suffices; not for load dump or high-power SMPS. |
| 5KP7.0A-E3/54 | Same electrical specs, identical P600 package, but commercial-grade (non-AEC-Q101) and RoHS-compliant only (E3 vs HE3). | Applicable in non-automotive industrial or consumer systems where automotive qualification is not mandated. | Choose for cost-sensitive designs where AEC-Q101 is unnecessary; verify lifecycle and traceability requirements match. |
Compared with SMBJ7.0AHE3/52 and 5KP7.0A-E3/54, the 5KP7.0AHE3/54 uniquely combines AEC-Q101 qualification, 5000 W surge capacity, and P600 thermal mass - making it the only option among the three validated for under-hood automotive power rail protection.

FAQ
What is the clamping voltage of the 5KP7.0AHE3/54 under maximum rated surge current?
The 5KP7.0AHE3/54 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 measured and guaranteed per JEDEC test conditions and ensures downstream 12 V logic and power devices remain within safe operating limits during surge events.
Is the 5KP7.0AHE3/54 suitable for automotive applications?
Yes, the 5KP7.0AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its 175 °C maximum junction temperature, robust P600 package, and validated performance under load dump and ISO 7637-2 transients make it appropriate for engine control units, body electronics, and ADAS power supplies.
What does the "HE3" suffix indicate in 5KP7.0AHE3/54?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes the automotive-grade version from the commercial "E3" variant (5KP7.0A-E3/54), confirming enhanced reliability testing and tighter process controls required for automotive deployment.
How does the 5KP7.0AHE3/54 differ from the 5KP7.0A-E3/54?
The 5KP7.0AHE3/54 and 5KP7.0A-E3/54 share identical electrical parameters and P600 packaging, but only the HE3 version is AEC-Q101 qualified and meets JESD 201 Class 2 whisker resistance. The E3 variant is commercial-grade and lacks automotive qualification - critical for OEM Tier 1 supply chain compliance.
Can the 5KP7.0AHE3/54 be used in bidirectional configurations?
No, the 5KP7.0AHE3/54 is unidirectional only, as confirmed in the Vishay datasheet. It conducts in reverse bias above VBR and blocks forward current - making it unsuitable for AC line protection or bidirectional data lines. For bidirectional protection, select a symmetric TVS like SMAJ7.0CAHE3/52.
