Product details
Overview
5KP6.5A-E3/73 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection. It features 5000 W peak pulse power (10/1000 μs), 6.5 V stand-off voltage, 7.22–7.98 V breakdown voltage at 50 mA, and clamps to ≤11.2 V at 446 A peak pulse current - deployed on power supply outputs and MOSFET gate drivers in automotive and industrial systems.
For engineers reviewing the 5KP6.5A-E3/73 datasheet, 5KP6.5A-E3/73 pinout, 5KP6.5A-E3/73 application, or 5KP6.5A-E3/73 equivalent, this page delivers verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, RoHS-compliant packaging, and real-world clamping performance under repetitive transients.
Technical Context
The 5KP6.5A-E3/73 operates as a unidirectional avalanche diode with glass-passivated P600 junction, optimized for fast response (<1 ns) and low incremental surge resistance. Its 175 °C maximum junction temperature and 8.0 W steady-state power dissipation support operation in thermally constrained environments without active cooling.
It is rated for 500 A non-repetitive forward surge current (8.3 ms half-sine), withstands solder dip up to 275 °C for 10 s, and meets JESD 201 Class 1A whisker resistance - confirming suitability for automotive-grade reflow and manual assembly processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.5 V - Maximum reverse operating voltage before significant leakage; sets upper limit for continuous DC bias in protected circuits. |
| VBR @ IT=50 mA | 7.22–7.98 V - Measured breakdown range confirms tight 10 % tolerance; ensures predictable turn-on during overvoltage events. |
| IPPM (10/1000 μs) | 446 A - Peak surge current capability defines clamping headroom against lightning or inductive switch-off transients. |
| VC @ IPPM | ≤11.2 V - Clamped voltage level protects downstream 12 V-rated ICs and MOSFETs from destructive overvoltage stress. |
| PPPM | 5000 W - Sustains high-energy surges without failure; enables replacement of crowbar circuits in switching power supplies. |
| TJ max. | 175 °C - High-temperature rating supports under-hood automotive use and industrial motor drive environments. |
| Polarity | Unidirectional - Cathode-banded configuration allows integration in DC-biased lines only; not suitable for AC or bidirectional signal paths. |
Pinout & Package
5KP6.5A-E3/73 uses the industry-standard P600 axial-leaded package: molded epoxy body with matte tin-plated leads, UL 94 V-0 rated, 0.340–0.360 inch (8.6–9.1 mm) body diameter, 0.375 inch (9.5 mm) lead length, and cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Cathode terminal | Marked end connects to system ground or lower-potential rail; reverse-biased during normal operation. |
| Cathode (non-banded end) | Anode terminal | Connects to protected line (e.g., +12 V rail); conducts when transient exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements - supports under-hood ECU, ADAS, and infotainment power rail protection. |
| 5000 W peak pulse power (10/1000 μs) | Enables single-device suppression of ISO 7637-2 Pulse 1/2a/5a transients without parallel staging or heat sinking. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot across protected components - critical for safeguarding logic-level MOSFET gates and microcontroller I/O. |
| RoHS-compliant, JESD 201 Class 1A whisker resistant | Ensures long-term reliability in high-vibration environments and compatibility with lead-free reflow profiles up to 260 °C. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive DC Bus |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients per ISO 16750-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery input and LDO/regulator input to clamp spikes before they reach sensitive analog/digital circuitry. Use Value: Withstands 5000 W surges and clamps to ≤11.2 V, preserving regulator input integrity and avoiding brownout resets during engine cranking. | Use Scenario: Safeguarding IGBT gate drivers and bus voltage monitors in variable-frequency drives exposed to inductive kickback. IC Role / Device Role / Timing Role: Mounted across DC bus rails to absorb energy from flyback diodes and snubbers during rapid IGBT turn-off. Use Value: 446 A peak current handling and 175 °C junction rating allow reliable operation in high-temperature cabinet environments without derating. |
| Switching Power Supply Output Clamping | Telecom Line Card Surge Protection |
Use Scenario: Replacing crowbar circuits on secondary-side outputs of 48 V telecom PSUs to avoid permanent shutdown after overvoltage. IC Role / Device Role / Timing Role: Connected in parallel with output capacitor to shunt transient energy while allowing fuse/breaker time to clear fault. Use Value: 5000 W rating and fast response enable self-resetting protection - system resumes operation after fuse replacement without component replacement. | Use Scenario: Protecting Ethernet PHY interfaces and PoE controllers from induced surges on copper data lines per IEC 61000-4-5 Level 4. IC Role / Device Role / Timing Role: Installed at board edge on DC bias lines feeding magnetics or PoE injectors to suppress common-mode transients. Use Value: 6.5 V VWM matches typical 5 V/3.3 V interface logic levels; low capacitance preserves signal integrity up to 100 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.5A | Lower peak power (600 W), smaller SMB package, same VWM/VBR range | Not suitable for ISO 7637-2 load dump; limited to board-level ESD and low-energy transients | Select when space-constrained PCB layout requires surface-mount and surge energy is <100 mJ. |
| 1.5KE6.8A | Same P600 package but lower peak power (1500 W), higher VBR (7.14–7.88 V), no AEC-Q101 qualification | Lacks automotive qualification and cannot sustain repeated 5000 W pulses without degradation | Choose only for cost-sensitive commercial power supplies where AEC-Q101 and full load-dump immunity are not required. |
Compared with SMBJ6.5A and 1.5KE6.8A, the 5KP6.5A-E3/73 uniquely combines automotive qualification, 5000 W surge capacity, and P600 robustness - making it the sole option among the three for ISO 16750-2-compliant 12 V rail protection in production vehicles.

FAQ
What is the maximum clamping voltage of the 5KP6.5A-E3/73 under peak surge conditions?
The 5KP6.5A-E3/73 has a maximum clamping voltage (VC) of 11.2 V when subjected to its rated peak pulse current of 446 A using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream 12 V logic components remain within safe operating limits during surge events.
Is the 5KP6.5A-E3/73 qualified for automotive applications?
Yes, the 5KP6.5A-E3/73 is AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number: 88308). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and humidity bias, validating its use in automotive power distribution modules, body control units, and engine control systems.
What does the "-E3/73" suffix indicate in the 5KP6.5A-E3/73 part number?
The "-E3" denotes RoHS-compliant, commercial-grade packaging with JESD 201 Class 1A whisker resistance; "/73" specifies the preferred packaging code - 73 indicates 800 pieces per 13-inch paper tape and reel. This format aligns with Vishay's ordering nomenclature for P600 devices and ensures correct material traceability and assembly compatibility.
Can the 5KP6.5A-E3/73 be used in bidirectional signal lines?
No, the 5KP6.5A-E3/73 is unidirectional only, as explicitly stated in the Vishay datasheet. It must be installed with correct polarity - cathode to the protected line, anode to ground - and cannot suppress negative-going transients on AC or differential signal paths. For bidirectional protection, a separate device such as the 5KP6.5CA is required.
How does thermal derating affect the 5KP6.5A-E3/73's peak pulse power capability above 25 °C?
Per Figure 2 in the Vishay datasheet, the 5KP6.5A-E3/73's peak pulse power (PPPM) is linearly derated above 25 °C ambient: at 100 °C, it retains ~75 % of rated 5000 W; at 150 °C, ~50 %. This derating reflects junction temperature rise during repetitive surges and must be accounted for in high-temperature enclosure designs.
