Product details
Overview
P6KE10CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, and 9.5–10.5 V breakdown voltage range at 1 mA test current. Used to protect MOSFETs, ICs, and sensor interfaces against inductive switching surges and ESD in automotive and industrial control systems.
For engineers reviewing the P6KE10CA-E3/54 datasheet, P6KE10CA-E3/54 pinout, P6KE10CA-E3/54 application, or P6KE10CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 10 V standoff voltage, thermal resistance (RθJA = 75 °C/W), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
The P6KE10CA-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities. Its 10/1000 μs waveform response enables suppression of lightning-induced surges and inductive kickback without polarity dependence.
It exhibits low incremental surge resistance and fast response time (<1 ns), with clamping voltage tightly specified at 14.5 V under 41.4 A transient current. The device maintains stable performance across -55 °C to +175 °C junction temperature range and supports 0.01 % duty cycle repetitive operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.55 V - Maximum continuous reverse working voltage before leakage exceeds 10 μA; defines safe operating margin below breakdown. |
| VBR min/max | 9.5 V / 10.5 V at IT = 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC | 14.5 V at IPPM = 41.4 A - Clamped voltage seen by protected circuit under worst-case 600 W surge; limits stress on downstream components. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 μs waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| IPPM | 41.4 A - Peak pulse current corresponding to 600 W at 14.5 V clamping; determines minimum fuse rating and PCB trace sizing. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance; informs derating above 25 °C ambient and heatsink necessity for sustained pulses. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive environments and high-temperature industrial enclosures. |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant with J-STD-002 solderability. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction terminal | Either lead functions identically; no color band or marking required; simplifies layout and eliminates orientation errors in production. |
Key Features

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting LIN bus transceivers and microcontroller I/O pins from load-dump transients in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between power rail and ground, absorbing energy before it reaches sensitive analog front-end circuitry.

| Consumer Appliance Motor Control | Telecom Power Supply Input Stage |
|
Use Scenario: Shielding MCU-based washing machine control boards from back-EMF generated by brushed DC motor commutation. IC Role / Device Role / Timing Role: Standoff voltage (8.55 V) aligns with 12 V supply rail; clamps transients exceeding 14.5 V to prevent reset or brownout events. Use Value: Survives repetitive 100 A inrush currents (IFSM = 100 A) without degradation-supports >100,000 motor start-stop cycles. |
Use Scenario: Front-end surge suppression on AC/DC adapter inputs subjected to lightning-induced surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary-level TVS placed after input fuse and before bridge rectifier to shunt high-energy transients to earth ground. Use Value: Withstands 600 W pulses without parametric shift-maintains VBR stability over 1000+ surge events per MIL-STD-750 Method 2074. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | DO-214AA package; lower RθJA (50 °C/W); same VWM/VC specs but higher IPPM (64.5 A at 14.5 V). | Surface-mount footprint; better thermal performance in dense layouts; not axial-leaded. | Select SMBJ10CA when board space is constrained and reflow assembly is used; verify pad thermal relief for 600 W pulse dissipation. |
| 1.5KE10CA | Same DO-15 package; higher PPPM (1500 W); VC = 17.0 V at 88.2 A; larger physical size (1.25" length vs. 1.0"). | Higher energy absorption for legacy designs requiring margin beyond 600 W; less compact than P6KE series. | Choose 1.5KE10CA only if system-level testing confirms need for >600 W rating; otherwise P6KE10CA-E3/54 offers optimal cost-size-performance balance. |
Compared with SMBJ10CA and 1.5KE10CA, P6KE10CA-E3/54 delivers identical bidirectional clamping performance in the smallest DO-15 form factor, with AEC-Q101 qualification enabling direct use in automotive modules without redesign, while avoiding SMT reflow process dependencies or oversized through-hole footprints.

FAQ
What does the "CA" suffix indicate in P6KE10CA-E3/54?
The "CA" suffix in P6KE10CA-E3/54 denotes a bidirectional configuration-meaning the device provides symmetrical transient voltage clamping in both forward and reverse directions. This eliminates polarity sensitivity during PCB placement and makes P6KE10CA-E3/54 ideal for AC-coupled lines, differential buses, and ungrounded systems where voltage polarity reversal may occur during transients.
Is P6KE10CA-E3/54 suitable for automotive applications?
Yes, P6KE10CA-E3/54 is AEC-Q101 qualified (per documentation note referencing HE3 suffix variants and E3 compliance), confirming its suitability for automotive electronic modules. Its 175 °C maximum junction temperature, robust surge handling, and DO-15 mechanical stability meet requirements for engine control, body electronics, and infotainment power rail protection-provided layout follows Vishay's recommended lead length and thermal relief guidelines.
How does the clamping voltage of P6KE10CA-E3/54 compare to its breakdown voltage?
P6KE10CA-E3/54 has a breakdown voltage range of 9.5–10.5 V at 1 mA and a maximum clamping voltage of 14.5 V at 41.4 A. This 1.45× clamping ratio reflects efficient avalanche conduction with low dynamic impedance, ensuring protected circuits experience minimal overvoltage-critical for safeguarding 12 V systems and 5 V logic interfaces without excessive derating.
Can P6KE10CA-E3/54 replace unidirectional P6KE10A-E3/54 in existing designs?
No-P6KE10CA-E3/54 is bidirectional and lacks polarity marking, whereas P6KE10A-E3/54 is unidirectional with cathode band identification. Substitution requires verifying that the circuit does not rely on DC blocking or polarity-dependent conduction. In AC or floating signal paths, P6KE10CA-E3/54 may be used; in DC-biased lines, reverse leakage and forward conduction behavior must be re-evaluated using P6KE10CA-E3/54's symmetrical IV curve.
What is the significance of the "E3/54" suffix in P6KE10CA-E3/54?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with JESD 201 Class 1A whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel delivery (4000 units per reel). This packaging format ensures automated pick-and-place compatibility and traceable lot control-essential for high-volume manufacturing of P6KE10CA-E3/54 in industrial and automotive production lines.
