Product details
Overview
5KP6.5AHE3/54 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), 6.5 V stand-off voltage (VWM), 7.22–7.98 V breakdown voltage (VBR at 50 mA), and clamps transients to ≤11.2 V at 446 A peak pulse current - used in automotive power supply output protection and industrial sensor interface circuits.
For engineers reviewing the 5KP6.5AHE3/54 datasheet, 5KP6.5AHE3/54 pinout, 5KP6.5AHE3/54 application, or 5KP6.5AHE3/54 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 175 °C max junction temperature, RoHS-compliant matte tin leads, and P600 package thermal performance under repetitive surge conditions.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its VBR, limiting transient energy to protected downstream circuitry. Its glass-passivated P600 chip junction delivers low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of inductive switching spikes and lightning-induced surges.
The 5KP6.5AHE3/54 is rated for 5000 W peak pulse power with 10/1000 µs waveform at 0.01% duty cycle, and supports 600 A non-repetitive forward surge current (8.3 ms half-sine). Its thermal design relies on lead temperature derating (max 75 °C at 8.0 W dissipation) and requires adequate PCB copper area for heatsinking during transient events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - maximum continuous reverse operating voltage before leakage exceeds 2000 µA |
| VBR (min/max) | 7.22 V / 7.98 V at 50 mA - ensures reliable avalanche initiation within tight tolerance band |
| VC @ IPPM | 11.2 V at 446 A - clamping voltage defines worst-case overvoltage seen by protected IC or MOSFET |
| PPPM | 5000 W - peak pulse power handling capability with standardized 10/1000 µs waveform |
| TJ max | 175 °C - enables operation in under-hood automotive environments and high-ambient industrial settings |
| Polarity | Unidirectional - cathode marked by color band; blocks forward conduction above ~3.5 V |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
5KP6.5AHE3/54 uses the P600 axial-leaded package: molded epoxy body with glass-passivated junction, UL 94 V-0 flammability rating, and matte tin-plated leads solderable per J-STD-002. Polarity is indicated by a cathode band; no separate anode/cathode labeling beyond band orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry / reverse voltage reference node | Connected to lower-potential side of protected line; determines direction of clamping action |
| Cathode (banded end) | Avalanche conduction terminal / clamping output | Connected to higher-potential rail (e.g., +12 V); conducts surge current to ground when VRM exceeded |
Key Features
| Feature | Design Value |
|---|---|
| 5000 W peak pulse power | Enables single-device protection against ISO 7637-2 Pulse 5a (load dump) in 12 V automotive systems |
| AEC-Q101 qualification | Validates robustness for automotive powertrain and body electronics without additional qualification testing |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes stress on downstream components during surge events compared to higher-ratio TVS devices |
| P600 package thermal mass | Supports 8.0 W steady-state dissipation at 75 °C lead temperature, aiding heat spreading during repeated transients |
| Uni-directional architecture | Prevents unintended forward conduction in DC-biased applications while maintaining full reverse surge capability |
Applications
| Automotive Power Supply Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump transients up to 120 V during alternator regulation failure. IC Role / Device Role / Timing Role: Primary clamping element placed between battery input and upstream fuse or DC-DC converter input.

IC Role / Device Role / Timing Role: Voltage-triggered shunt device across output capacitor, conducting only during overvoltage faults. Use Value: Withstands repeated 8.3 ms surges up to 600 A, allowing fuse interruption while enabling system reset post-fault. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5AHE3/52 | Lower peak pulse power (600 W), SMC package, same VWM/VBR range | Suitable for board space-constrained designs with lower surge exposure (e.g., consumer USB ports) | Select when footprint and weight are critical and surge threat level is below ISO 16750-2 Class III |
| 1.5KE6.8A | Same P600 package but lower PPPM (1500 W), higher VC (11.5 V), non-AEC-Q101 | Acceptable for cost-sensitive industrial controls where automotive qualification is not required | Choose for legacy designs needing drop-in replacement with reduced surge margin and no automotive validation |
Compared with SMBJ6.5AHE3/52 and 1.5KE6.8A, the 5KP6.5AHE3/54 delivers 3.3× higher surge energy absorption and AEC-Q101 validation - essential for automotive load-dump immunity and high-reliability industrial power rails where sustained thermal dissipation matters.

FAQ
What is the clamping voltage of the 5KP6.5AHE3/54 under maximum surge conditions?
The 5KP6.5AHE3/54 clamps to a maximum of 11.2 V when subjected to its rated peak pulse current of 446 A (10/1000 µs waveform). This value is measured at the device terminals and represents the upper limit of voltage imposed on protected circuitry during a full-rated transient event. The clamping voltage remains stable across temperature due to the device's low temperature coefficient of VBR (0.065 %/°C).
Is the 5KP6.5AHE3/54 suitable for automotive applications?
Yes, the 5KP6.5AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its 175 °C maximum junction temperature, robust P600 package, and validated performance under temperature cycling and high-humidity bias life testing make it appropriate for engine control modules, body control units, and ADAS power supplies where load dump and jump-start surges occur.
How does the 5KP6.5AHE3/54 differ from the 5KP6.5A-E3/54 variant?
The 5KP6.5AHE3/54 differs from 5KP6.5A-E3/54 solely in qualification level: the "HE3" suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas "E3" indicates commercial-grade RoHS compliance only. Both share identical electrical specs, P600 package, and 5000 W pulse rating - the HE3 version adds automotive reliability validation.
What is the maximum reverse leakage current for the 5KP6.5AHE3/54 at its stand-off voltage?
At its 6.5 V stand-off voltage (VWM), the 5KP6.5AHE3/54 exhibits a maximum reverse leakage current of 2000 µA at 25 °C. This value increases with temperature but remains within specification limits up to 175 °C junction temperature, ensuring minimal standby power loss in always-on automotive modules.
Can the 5KP6.5AHE3/54 be used in bidirectional configurations?
No, the 5KP6.5AHE3/54 is unidirectional only, with cathode marked by a color band. For bidirectional protection, two 5KP6.5AHE3/54 devices must be connected in series opposition - though this configuration doubles VC and reduces effective surge capacity. Vishay offers dedicated bidirectional variants (e.g., 5KP6.5CA) for such use cases.
