Product details
Overview
5KP64-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in P600 package, designed for high-energy surge protection of DC power rails and signal lines. It features 5000 W peak pulse power (10/1000 μs), 64 V stand-off voltage (VWM), 71.1–78.6 V breakdown voltage (VBR at 5.0 mA), and clamps transients to ≤103 V at 48.5 A peak pulse current - deployed in automotive power supply outputs and industrial sensor interfaces.
For engineers reviewing the 5KP64-E3/54 datasheet, 5KP64-E3/54 pinout, 5KP64-E3/54 application, or 5KP64-E3/54 equivalent, this page delivers verified electrical ratings, AEC-Q101 qualification status, thermal derating behavior, clamping performance under repetitive surges, and RoHS-compliant packaging details for robust overvoltage design validation.
Technical Context
This TVS diode uses a glass-passivated P600 chip junction optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of inductive switching spikes and lightning-induced transients. Its unidirectional polarity supports DC-biased rail protection with defined cathode marking and 3.5 V forward voltage at 100 A.
The device operates across –55 °C to +175 °C junction temperature range and is rated for 8.0 W steady-state power dissipation on an infinite heatsink at 75 °C lead temperature. It meets JESD 201 Class 1A whisker testing and UL 94 V-0 flammability requirements via molded epoxy encapsulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected line. |
| VBR (min/max) | 71.1 V / 78.6 V at 5.0 mA - Breakdown threshold range ensures reliable turn-on during overvoltage events without premature conduction. |
| PPPM | 5000 W - Peak pulse power handling capability with 10/1000 μs waveform; enables survival of high-energy transients like ISO 7637-2 Pulse 5a. |
| VC @ IPPM | ≤103 V at 48.5 A - Clamped voltage level determines maximum stress imposed on downstream ICs during surge events. |
| IFSM | 600 A - Peak forward surge current rating (8.3 ms half-sine); supports crowbar-like fault clearing in power supply protection circuits. |
| TJ max | +175 °C - Maximum junction temperature allows operation in under-hood automotive environments and high-ambient industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard; suitable for safety-critical ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ64A | Lower peak pulse power (400 W), SMA package (lower thermal mass), 64 V VWM, 71.1–78.6 V VBR, 103 V VC at 3.9 A. | Suitable for low-energy signal-line protection only; not rated for automotive load dump or industrial power rail duty. | Select when space-constrained PCB layout requires SMD mounting and surge energy is limited to <500 W. |
| ON Semiconductor 1.5KE68A | Same P600 package, 68 V VWM, 75.6–83.6 V VBR, 110 V VC at 45.5 A, 1500 W PPPM, no AEC-Q101 qualification. | Acceptable for commercial/industrial power rails but lacks automotive qualification and 5000 W capability. | Choose for cost-sensitive non-automotive designs where 1500 W surge handling suffices and AEC-Q101 is not required. |
Compared with SMAJ64A and 1.5KE68A, the 5KP64-E3/54 delivers 3.3× higher pulse power than the SMAJ64A and over 3× higher than the 1.5KE68A, while maintaining identical clamping voltage and adding AEC-Q101 validation - making it the sole option for high-reliability 64 V rail protection in automotive and heavy-industrial settings.

FAQ
What is the clamping voltage of the 5KP64-E3/54 under maximum surge conditions?
The 5KP64-E3/54 clamps to a maximum of 103 V when subjected to its rated peak pulse current of 48.5 A (10/1000 μs waveform). This value is measured per JEDEC standards and represents the upper limit of voltage seen by downstream circuitry during worst-case transient events, ensuring compatibility with 75 V-rated components.
Is the 5KP64-E3/54 suitable for automotive applications?
Yes, the 5KP64-E3/54 is AEC-Q101 qualified and explicitly validated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, P600 package mechanical robustness, and 5000 W surge rating meet requirements for protecting engine control units, ADAS power supplies, and body electronics against ISO 16750-2 load dump events.
What does the "E3/54" suffix mean in 5KP64-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "54" denotes the preferred package code for 13-inch paper tape and reel packaging containing 800 units. This ordering format aligns with Vishay's standardized delivery mode nomenclature for P600 devices.
How does the 5KP64-E3/54 compare to bidirectional TVS diodes?
The 5KP64-E3/54 is unidirectional and intended for DC-biased lines where reverse polarity is not expected. Unlike bidirectional variants, it offers lower leakage current (<2.0 μA at VWM) and tighter VBR tolerance, making it optimal for 64 V positive-rail protection. Bidirectional versions would be inappropriate here due to unnecessary reverse conduction path and higher capacitance.
Can the 5KP64-E3/54 replace a 1.5KE68A in an existing design?
No direct replacement is recommended: although both use P600 packages, the 5KP64-E3/54 has higher VWM (64 V vs. 68 V), different VBR range (71.1–78.6 V vs. 75.6–83.6 V), and significantly greater surge capacity (5000 W vs. 1500 W). Circuit analysis must confirm whether the higher clamping energy and altered voltage thresholds affect system-level protection margins before substitution.
