Product details
Overview
5KP64A-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection on power rails and signal lines. It features 64 V stand-off voltage (VWM), 71.1–78.6 V breakdown voltage (VBR) at 5 mA, 103 V clamping voltage (VC) at 48.5 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used to protect MOSFETs and ICs against lightning-induced transients in automotive power supplies.
For engineers reviewing the 5KP64A-E3/54 datasheet, 5KP64A-E3/54 pinout, 5KP64A-E3/54 application, or 5KP64A-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected device's absolute maximum rating, unidirectional polarity requirement, P600 thermal dissipation capability, and compliance with AEC-Q101 for under-hood automotive use.
Technical Context
The 5KP64A-E3/54 operates as a silicon avalanche diode with glass-passivated P600 junction, delivering fast response (<1 ns) and low incremental surge resistance to clamp transient overvoltages before downstream components fail. Its unidirectional structure allows reverse-biased operation across DC power rails, where it remains non-conductive below 64 V and avalanches sharply above 71.1 V.
It is rated for 5000 W peak pulse power (10/1000 μs), 500 A non-repetitive forward surge current (8.3 ms half-sine), and operates from –55 °C to +175 °C. The device meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker resistance, with matte tin-plated leads and UL 94 V-0 epoxy molding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64 V - Maximum continuous reverse operating voltage before leakage exceeds 2 µA; sets upper limit for safe DC rail placement. |
| VBR min/max | 71.1 V / 78.6 V at 5 mA - Confirmed avalanche onset range; ensures reliable triggering without premature conduction. |
| VC @ IPPM | 103 V at 48.5 A - Clamped voltage during 10/1000 μs surge; must stay below protected IC's absolute max rating. |
| PPPM | 5000 W - Peak transient energy handling capacity; enables protection against IEC 61000-4-5 Level 4 surges. |
| TJ max | +175 °C - Maximum junction temperature; supports under-hood automotive environments with minimal derating. |
| Polarity | Unidirectional - Cathode-marked device; suitable only for DC-biased applications, not AC line protection. |
| Package | P600 - Axial-leaded, 9.5 mm body length; provides mechanical robustness and thermal mass for high-energy dissipation. |
Pinout & Package
P600 package: axial-leaded, molded epoxy body with glass-passivated junction; cathode indicated by color band; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit (e.g., ground or return path); conducts during positive transients when cathode is biased higher. |
| Cathode | Avalanche clamping terminal | Marked end (color band); connected to higher-potential side (e.g., +12 V rail); avalanches into conduction when reverse voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use per stress test requirements including HTOL, TCT, and ESD HBM ≥ 2 kV. |
| 5000 W peak pulse power | Withstands IEC 61000-4-5 combination wave (1.2/50 μs voltage, 8/20 μs current) up to Level 4 (4 kV/2 kA) without failure. |
| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes overvoltage stress on protected devices; e.g., clamps 103 V at 48.5 A while VBR starts at 71.1 V. |
| P600 thermal mass | Enables 8.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C; supports repeated surge events with adequate PCB copper area. |
| UL 94 V-0 molding | Self-extinguishing epoxy housing prevents flame propagation in enclosed automotive or industrial enclosures. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A-E3/52 | Lower PPPM (600 W), smaller SMB package, same VWM/VBR/VC specs, but limited to 100 A IFSM and 1.5 W PD. | Suitable for low-energy signal-line protection; insufficient for automotive load dump or industrial 24 V rail clamping. | Select 5KP64A-E3/54 when peak surge energy exceeds 600 W or ambient temperature exceeds 85 °C. |
| 1.5KE68A | Same P600 package and 5000 W rating, but higher VWM (68 V), VBR (75.6–83.6 V), and VC (110 V); not AEC-Q101 qualified. | Acceptable for commercial/industrial power supplies where automotive qualification is unnecessary and 110 V clamping is tolerable. | Choose 5KP64A-E3/54 for AEC-Q101 compliance and tighter clamping (103 V vs. 110 V) in safety-critical systems. |
Compared with SMBJ64A-E3/52 and 1.5KE68A, the 5KP64A-E3/54 uniquely combines AEC-Q101 qualification, 5000 W capability, and 103 V clamping in P600 - making it the only option among the three validated for automotive load dump and high-reliability industrial power entry protection.

FAQ
What is the clamping voltage of the 5KP64A-E3/54 under a 10/1000 μs surge?
The 5KP64A-E3/54 clamps to a maximum of 103 V when subjected to its rated peak pulse current of 48.5 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and represents the upper limit of voltage seen by downstream components during surge events. The 5KP64A-E3/54 maintains this clamping performance across its full operating temperature range from –55 °C to +175 °C.
Is the 5KP64A-E3/54 suitable for automotive applications?
Yes, the 5KP64A-E3/54 is AEC-Q101 qualified and explicitly designed for automotive use, including under-hood environments. Its +175 °C maximum junction temperature, robust P600 package, and validation across HTOL, temperature cycling, and ESD tests make it appropriate for protecting engine control modules, body control units, and ADAS power supplies. The 5KP64A-E3/54 meets the reliability and thermal demands required by automotive OEMs.
What does the "E3/54" suffix mean in 5KP64A-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "54" denotes the preferred packaging code for 13-inch paper tape and reel, with a base quantity of 800 units per reel. This ordering format ensures consistent assembly-line feeding and complies with Vishay's standardized packaging nomenclature. The 5KP64A-E3/54 is not AEC-Q101 qualified - that requires the "HE3" suffix variant.
How does the 5KP64A-E3/54 differ from bidirectional TVS diodes?
The 5KP64A-E3/54 is unidirectional and functions only as a reverse-biased clamp - it conducts during negative transients relative to its cathode. Unlike bidirectional TVS diodes, it cannot protect AC signals or floating differential lines. Its unidirectional nature yields lower leakage and sharper breakdown, making it ideal for DC power rail protection where polarity is fixed. The 5KP64A-E3/54 must be oriented with cathode toward the higher-potential rail.
Can the 5KP64A-E3/54 replace a fuse or circuit breaker?
No, the 5KP64A-E3/54 is not a replacement for fuses or breakers but works alongside them. It clamps overvoltages within nanoseconds to protect sensitive components, allowing time for upstream overcurrent protection to operate. Per Vishay application notes, the 5KP64A-E3/54 enables system reset after transient events - unlike crowbar circuits that latch short - preserving functionality after surge clearance without requiring fuse replacement.
