Product details
Overview
P4KE10CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 27.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and microcontroller I/O in automotive and industrial control systems.
For engineers reviewing the P4KE10CA-E3/54 datasheet, P4KE10CA-E3/54 pinout, P4KE10CA-E3/54 application, or P4KE10CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 leaded package compatibility, 10 V working voltage tolerance, thermal resistance (RθJL = 66 °C/W), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<10 μA at 8.55 V), while fast response time (<1 ns) limits transient energy delivered to downstream circuitry.
The device complies with AEC-Q101 for automotive use and supports soldering per J-STD-002 and JESD 22-B102. With 175 °C max junction temperature and 66 °C/W junction-to-lead thermal resistance, it sustains repetitive surge events under constrained PCB thermal conditions when mounted with ≥10 mm lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - maximum continuous reverse voltage before clamping begins; defines safe operating range for protected line |
| VBR min/max | 9.5 V / 10.5 V at 1 mA - precise breakdown threshold ensures predictable clamping onset |
| VC @ IPPM | 14.5 V at 27.6 A - clamping voltage during 10/1000 μs surge; determines max stress on downstream ICs |
| PPPM | 400 W - peak pulse power handling with standard 10/1000 μs waveform; validates robustness against common ESD/lightning surges |
| TJ max | +175 °C - enables operation in under-hood automotive environments and high-ambient industrial settings |
| RθJL | 66 °C/W - junction-to-lead thermal resistance; informs heatsinking requirements for repeated surge duty |
| ID @ VWM | 10 μA - reverse leakage at stand-off voltage; critical for low-power sensor or battery-backed circuits |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; no polarity marking required for bidirectional operation. Body dimensions: 25.4 mm min length × 5.2 mm max diameter; lead diameter 0.86 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (in one direction) | Connects to line being protected; forms symmetrical conduction path with cathode during overvoltage |
| Cathode | Transient current entry (in opposite direction) | Completes bidirectional clamping loop; no color band or marking distinguishes terminals |
Key Features
| Feature | Design Value |

| 400 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 3 surges (1 kV open-circuit, 500 A short-circuit) without degradation |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during transients - critical for protecting 3.3 V or 5 V logic interfaces |
| UL 94 V-0 molding compound | Self-extinguishing epoxy meets fire-safety requirements for enclosed industrial and transportation equipment |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., temperature, pressure) from load dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential signal pair or supply rail to limit transient excursions below IC absolute maximum ratings. Use Value: Prevents latch-up or permanent damage to 5 V tolerant transceivers and ADC front-ends during 12 V system load dump events (ISO 7637-2 Pulse 5a). | Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to relay coil flyback and motor drive noise in factory automation cabinets. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing >400 W surge energy from 24 V DC control lines during contactor switching. Use Value: Maintains signal integrity and prevents false triggering of opto-isolated inputs during repetitive 10/1000 μs surges up to 27.6 A. |
| Consumer Power Adapter Input | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for USB-C PD and smart home hubs subjected to lightning-induced surges on DC output rails. IC Role / Device Role / Timing Role: Clamping device across +VOUT/GND to shunt transient energy before it reaches DC-DC converters and USB port controllers. Use Value: Limits clamped voltage to 14.5 V - well below 20 V absolute maximum of common buck controllers and USB-PD PHY ICs. | Use Scenario: Protecting Ethernet PHY magnetics and RJ45 interface ICs from induced surges on unshielded twisted-pair cabling in enterprise VoIP phones and network switches. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential pairs (e.g., TX+/TX−) to suppress common-mode transients without disrupting DC bias or signal integrity. Use Value: Symmetrical clamping preserves differential signaling margin while meeting IEC 61000-4-5 surge immunity requirements for Class B equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | DO-214AA package; 600 W PPPM; lower RθJA (50 °C/W); same VWM (8.55 V) and VC (14.5 V) | Better thermal performance in surface-mount layouts; higher surge rating but larger footprint | Select SMBJ10CA when board space allows SMT placement and higher surge margin is needed beyond 400 W |
| 1.5KE10CA | DO-201 package; 1500 W PPPM; same VWM (8.55 V); VC = 15.6 V at 96.8 A | Higher power handling for infrequent, high-energy events; larger axial package requires more board area | Choose 1.5KE10CA for legacy through-hole designs requiring >1 kW surge capability in non-automotive industrial settings |
Compared with SMBJ10CA and 1.5KE10CA, P4KE10CA-E3/54 offers optimal balance of AEC-Q101 qualification, DO-41 compatibility with existing through-hole tooling, and verified 400 W surge performance - making it preferred for cost-sensitive, volume automotive and industrial control applications where footprint and qualification alignment matter.

FAQ
What is the standoff voltage rating of the P4KE10CA-E3/54?
The P4KE10CA-E3/54 has a maximum working standoff voltage (VWM) of 8.55 V, meaning it remains non-conductive up to this DC or RMS voltage level. This value is derived from the 10 V nominal breakdown voltage and ensures reliable operation in 5 V–9 V systems without leakage-related power loss or false triggering.
Is the P4KE10CA-E3/54 suitable for automotive applications?
Yes, the P4KE10CA-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its 175 °C maximum junction temperature, glass-passivated junction, and DO-41 mechanical robustness meet requirements for engine bay, chassis, and body control module deployments - confirmed in Vishay document 88365, revision 16-Sep-2021.
How does the bidirectional configuration of P4KE10CA-E3/54 affect circuit layout?
The P4KE10CA-E3/54 has no polarity marking and conducts identically in both directions, simplifying layout for AC-coupled or differential lines like CAN, RS-485, or audio interfaces. Unlike unidirectional TVS diodes, it eliminates orientation errors during assembly and avoids the need for dual-device configurations to achieve symmetrical protection.
What is the clamping voltage of P4KE10CA-E3/54 under surge conditions?
The P4KE10CA-E3/54 clamps to a maximum of 14.5 V when subjected to its rated 27.6 A peak pulse current (10/1000 μs waveform). This clamping voltage is guaranteed across temperature and lifetime, ensuring downstream 3.3 V or 5 V ICs remain within safe operating limits during transient events.
Does P4KE10CA-E3/54 require heatsinking in typical applications?
No external heatsink is required for single-event surge suppression, as the P4KE10CA-E3/54 dissipates energy transiently. However, its 66 °C/W junction-to-lead thermal resistance means sustained or repetitive surges demand adequate copper pour and ≥10 mm lead length to maintain TJ ≤ 175 °C - per Vishay's thermal derating curve in figure 2 of document 88365.
