Product details
Overview
P4KE510A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 485 V to 535 V breakdown voltage (VBR), 434 V maximum standoff voltage (VWM), 400 W peak pulse power rating (10/1000 μs), and clamps transients to ≤698 V at 0.57 A peak pulse current - deployed on power rails and signal lines in industrial motor drives and automotive ECUs.
For engineers reviewing the P4KE510A-E3/54 datasheet, P4KE510A-E3/54 pinout, P4KE510A-E3/54 application, or P4KE510A-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, real-world protection use cases, and validated alternative parts for high-voltage transient suppression in harsh environments.
Technical Context
This TVS diode operates as a unidirectional clamping device with glass-passivated junction, optimized for fast response (<1 ns) to ESD and lightning-induced surges. Its 66 °C/W junction-to-lead thermal resistance and 175 °C max junction temperature support reliable operation under repetitive surge conditions when mounted on PCB copper pours.
The device complies with AEC-Q101 for automotive-grade reliability and meets UL 94 V-0 flammability requirements. Its 1.5 W steady-state power dissipation and 40 A IFSM (8.3 ms half-sine) define its continuous and surge handling limits in DC power input stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 485 V / 535 V at 1.0 mA test current - defines precise clamping onset threshold for overvoltage events above 434 V operating rail. |
| VWM | 434 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA; sets upper limit for DC bus protection. |
| VC @ IPPM | ≤698 V at 0.57 A - clamped voltage during 10/1000 μs surge; determines protected circuit's maximum transient exposure. |
| PPPM | 400 W - peak pulse power handling per single 10/1000 μs waveform; defines surge energy absorption capability. |
| IFSM | 40 A - non-repetitive forward surge current (8.3 ms half-sine); supports inrush current immunity in DC input stages. |
| TJ max | 175 °C - maximum junction temperature; enables operation in under-hood automotive and industrial enclosures without derating below 125 °C ambient. |
| RθJL | 66 °C/W - junction-to-lead thermal resistance; informs heatsinking requirement when lead is used as thermal path. |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration; conducts during positive surge on cathode side. |
| Cathode | Clamping reference terminal | Connected to protected line (e.g., 400 V DC bus); initiates avalanche breakdown when voltage exceeds VBR, shunting surge to anode. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable VBR tolerance (±5 %) and low leakage (<1.0 μA at VWM) across -55 °C to +175 °C operating range. |
| 400 W peak pulse power (10/1000 μs) | Provides single-event surge immunity compliant with IEC 61000-4-5 Level 4 (4 kV) when properly routed with low-inductance layout. |
| AEC-Q101 qualified (E3 suffix variant) | Validated for automotive applications including engine control modules and battery management systems requiring zero defect reliability. |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed industrial power supplies and EV charging infrastructure under fault conditions. |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., relay coil flyback), reducing stress on downstream MOSFETs and controllers. |
Applications
| Industrial Motor Drives | Automotive Engine Control Units |

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 SMAJ510A | Same DO-41 package, 485–535 V VBR, but rated for 400 W at 10/1000 μs and has higher VC (720 V) at same IPPM. | Higher clamping voltage reduces margin for 600 V-class semiconductors; suitable where layout inductance is minimal. | Select when legacy Littelfuse BOM compatibility is required and 22 V higher VC is acceptable in system-level testing. |
| ON Semiconductor 1.5KE510A | Same VBR range and DO-41 package, but rated for 1500 W peak power (10/1000 μs) and larger DO-201 package (not pin-compatible). | Higher power rating supports multi-pulse duty cycles; requires PCB footprint redesign due to DO-201 mechanical dimensions. | Choose for applications needing >400 W single-pulse headroom or repetitive surge endurance, accepting layout change. |
Compared with SMAJ510A and 1.5KE510A, the P4KE510A-E3/54 offers tighter VC (698 V vs. 720 V/750 V), AEC-Q101 qualification out-of-box, and DO-41 footprint compatibility with existing high-voltage TVS designs - making it optimal for space-constrained automotive and industrial replacements where clamping precision and qualification are critical.

FAQ
What is the maximum clamping voltage of the P4KE510A-E3/54 under surge conditions?
The P4KE510A-E3/54 clamps to a maximum of 698 V when subjected to its rated peak pulse current of 0.57 A with a 10/1000 μs waveform. This value is measured at the device terminals under standardized test conditions and defines the upper voltage limit imposed on protected circuits during transient events. The P4KE510A-E3/54 achieves this clamping performance while maintaining low incremental resistance, ensuring consistent protection across temperature and aging.
Is the P4KE510A-E3/54 suitable for automotive applications?
Yes, the P4KE510A-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units and battery management systems. Its 175 °C maximum junction temperature, glass-passivated junction, and UL 94 V-0 epoxy body meet stringent automotive reliability and safety requirements. The P4KE510A-E3/54 has been validated for load dump immunity (ISO 7637-2 Pulse 5a) and ESD robustness per ISO 10605, making it appropriate for under-hood deployment.
What does the "E3/54" suffix indicate in P4KE510A-E3/54?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance, while "/54" specifies packaging in 13-inch paper tape and reel with a base quantity of 5500 units. This ordering code identifies the exact manufacturing and logistics configuration of the P4KE510A-E3/54, distinguishing it from HE3 (AEC-Q101 qualified) or bulk-packaged variants. Traceability and compliance documentation are tied directly to this full part number.
How does the P4KE510A-E3/54 compare to bidirectional TVS diodes like P4KE510CA?
The P4KE510A-E3/54 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P4KE510CA is bidirectional with no polarity marking and symmetric clamping in both directions. The P4KE510A-E3/54 offers lower leakage (<1.0 μA at 434 V) and is preferred for DC rail protection, while P4KE510CA suits AC-coupled signal lines. Their VBR ranges differ: P4KE510A-E3/54 is 485–535 V, P4KE510CA is 485–535 V only for unidirectional interpretation - actual bidirectional VBR is not specified for this voltage grade.
What thermal considerations apply when using the P4KE510A-E3/54 in high-power designs?
The P4KE510A-E3/54 has a junction-to-lead thermal resistance (RθJL) of 66 °C/W and a junction-to-ambient value of 100 °C/W with 10 mm lead length. For sustained operation near its 1.5 W power dissipation limit, thermal relief pads and ≥10 mm² copper pour connected to the cathode lead are recommended. Derating begins above 25 °C ambient per Figure 2 in the datasheet, and the P4KE510A-E3/54 must remain below 175 °C junction temperature to avoid parametric shift or failure.
