Product details
Overview
5KP7.0AHE3/73 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), clamps to ≤12.0 V at 417 A, and operates from –55 °C to +175 °C - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the 5KP7.0AHE3/73 datasheet, 5KP7.0AHE3/73 pinout, 5KP7.0AHE3/73 application, or 5KP7.0AHE3/73 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, P600 package dimensions, clamping performance under surge conditions, and direct alternatives for circuit protection redesigns requiring high-power transient suppression.
Technical Context
This TVS diode 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.
The device meets AEC-Q101 stress test requirements and supports repetitive surge duty cycles up to 0.01 % with 10/1000 µs waveform compliance. Thermal derating follows JEDEC curves, maintaining 5000 W capability only at TA = 25 °C and reducing linearly above that point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 7.0 V - Maximum continuous reverse voltage before significant leakage; sets operating margin below clamping onset. |
| VBR (Breakdown Voltage) | 7.78–8.60 V at 50 mA - Confirmed avalanche initiation range; ensures reliable turn-on during transients. |
| VC (Clamping Voltage) | ≤12.0 V at 417 A (10/1000 µs) - Limits downstream IC voltage stress during worst-case surge events. |
| PPPM (Peak Pulse Power) | 5000 W - Sustains single high-energy surges without failure; validated per JEDEC standard waveform. |
| IFSM (Surge Current) | 600 A (8.3 ms half-sine) - Withstands repetitive line-frequency overloads common in AC-DC front-ends. |
| TJ max. | +175 °C - Enables placement near hot components (e.g., MOSFETs, transformers) without thermal derating loss. |
| Polarity | Unidirectional - Blocks reverse current until breakdown; suited for DC supply rail protection only. |
Pinout & Package
5KP7.0AHE3/73 is housed in a P600 axial-leaded package: molded epoxy body with matte tin-plated leads, UL 94 V-0 rated, 9.5 mm body length, 0.375" lead spacing, and cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Cathode terminal | Connected to protected line's higher potential side; clamps when voltage exceeds VBR relative to anode. |
| Cathode (non-banded end) | Anode terminal | Typically tied to ground or low-side reference; completes clamping path during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling, humidity, and mechanical shock. |
| 5000 W peak pulse rating | Handles IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without degradation in power supply input stages. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot across protected ICs - critical for 5 V logic and automotive microcontrollers. |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and automotive material compliance standards. |
| Fast response time (<1 ns) | Engages before ESD or lightning-induced transients damage sensitive gate oxides in MOSFET drivers. |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamp |
|---|---|
|
Use Scenario: 12 V battery-fed ECUs exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary crowbar-style overvoltage clamp on main DC input rail before DC-DC converter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Lower PPPM (600 W), smaller SMB package, same VWM/VBR range, no AEC-Q101 qualification. | Suitable for space-constrained consumer electronics but not automotive under-hood use. | Select when board area is limited and surge energy stays below 600 W. |
| 1.5KE7.0A | Same P600 package and 5000 W rating, but non-AEC-Q101, higher VC (12.5 V), and wider VBR tolerance (±10 %). | Acceptable for industrial power supplies where automotive qualification is unnecessary. | Choose for cost-sensitive industrial designs where AEC-Q101 is not mandated. |
Compared with SMBJ7.0A and 1.5KE7.0A, the 5KP7.0AHE3/73 uniquely combines AEC-Q101 qualification, 5000 W capability in P600, and tight 5 % VBR tolerance - making it the only option qualified for automotive power rail protection requiring both high energy handling and production-grade reliability.

FAQ
What is the clamping voltage of the 5KP7.0AHE3/73 under maximum surge current?
The 5KP7.0AHE3/73 clamps to a maximum of 12.0 V when subjected to its rated peak pulse current of 417 A using the standard 10/1000 µs waveform. This value is measured and guaranteed per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the 5KP7.0AHE3/73 qualified for automotive applications?
Yes, the 5KP7.0AHE3/73 carries the HE3 suffix, confirming full AEC-Q101 qualification. It has passed stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock - making it approved for under-hood and powertrain ECU use per automotive OEM requirements.
What does the "HE3" suffix mean in 5KP7.0AHE3/73?
The "HE3" suffix indicates RoHS-compliant construction with JESD 201 Class 2 whisker resistance and AEC-Q101 qualification. It distinguishes this variant from commercial-grade "E3" versions and confirms suitability for automotive production environments.
Can the 5KP7.0AHE3/73 replace a 1.5KE7.0A in an existing design?
The 5KP7.0AHE3/73 shares the same P600 package and comparable electrical specs with the 1.5KE7.0A, but offers tighter VBR tolerance (5 % vs. ±10 %) and AEC-Q101 qualification. PCB layout remains identical, though thermal and reliability margins improve significantly with the 5KP7.0AHE3/73.
What is the maximum operating temperature for the 5KP7.0AHE3/73?
The 5KP7.0AHE3/73 has a maximum junction temperature (TJ max.) of +175 °C and specified operation from –55 °C to +175 °C. This allows direct mounting on heatsinks or placement near high-temperature components in engine control modules and industrial motor drives.
