Product details
Overview
P6KE75CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a 75V nominal standoff voltage, 108V maximum clamping voltage at 5.8A peak pulse current, 600W peak pulse power rating (10/1000μs), and DO-204AC (DO-15) axial package - deployed in automotive ECU power rails and industrial sensor I/O protection.
For engineers reviewing the P6KE75CA datasheet, P6KE75CA pinout, P6KE75CA application, or P6KE75CA equivalent, key selection criteria include bidirectional clamping symmetry, low dynamic impedance under surge, AEC-Q101 qualification status, junction temperature derating above 25°C, and compatibility with 10/1000μs waveform immunity testing per IEC 61000-4-5.
Technical Context
The P6KE75CA operates as a silicon avalanche diode with symmetrical bidirectional breakdown behavior, enabling protection of AC-coupled or floating signal paths without polarity sensitivity. Its clamping response initiates within 5.0ns from 0V to VBR, and it maintains <1μA reverse leakage at 60.7V (VWM) while supporting up to 175°C junction temperature.
Designed for non-repetitive surge events, the device delivers 600W peak pulse power at TA = 25°C and derates linearly above that ambient, with steady-state power dissipation limited to 5W at 75°C on specified copper pad layout. It complies with ANSI/IEEE C62.35 definitions for transient suppression parameters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 75 V - defines rated standoff level before avalanche conduction begins in either direction |
| Breakdown Voltage (Min/Max) | 71.3 V / 78.8 V - guaranteed symmetric VBR range at 1 mA test current, ensuring predictable turn-on |
| Standoff Voltage (VWM) | 64.1 V - maximum continuous reverse voltage the device blocks without significant leakage |
| Clamping Voltage (VC) | 103 V at 6.1 A - peak voltage seen across protected circuit during full 600W surge event |
| Peak Pulse Power | 600 W - energy-handling capability under standardized 10/1000μs waveform per IEC 61000-4-5 |
| Junction Temperature Range | –55°C to +175°C - enables operation in under-hood automotive and industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with tin-plated leads, UL 94V-0 molding |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking for unidirectional variants; P6KE75CA is bidirectional and has no polarity marking - both terminals are electrically identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as anode or cathode depending on instantaneous polarity of transient - no fixed orientation required in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per stress test plan |
| Fast 5.0ns response time | Enables clamping before transient energy couples into downstream ICs - critical for protecting CAN/LIN transceivers and microcontrollers |
| Low dynamic impedance | Ensures minimal voltage overshoot during high di/dt surges, maintaining clamping performance across varying surge amplitudes |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally constrained applications |
| UL recognition (E-326243) | Confirms safety compliance for end-equipment certification in North American markets |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12V/24V battery-fed ECUs against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converters and LDOs to limit input voltage excursion. Use Value: Clamps to ≤103 V during 600W surge, preventing overvoltage damage to downstream regulators rated for 40V max input. | Use Scenario: Shielding 4–20mA current loop transmitters from EFT bursts and lightning-induced surges on field wiring. IC Role / Device Role / Timing Role: Bidirectional shunt protector across analog input terminals, referenced to system ground. Use Value: Symmetric clamping ensures equal protection for positive/negative transients without polarity-dependent layout constraints. |
| Lighting System Surge Suppression | ESD Protection for Communication Ports |
Use Scenario: Safeguarding LED driver ICs in automotive headlamps exposed to inductive switching spikes from relay coils. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing energy from L·di/dt events generated by solenoid control circuits. Use Value: 600W rating handles repetitive 100V/10A spikes common in lamp-switching cycles without degradation. | Use Scenario: Adding secondary-level protection to RS-485 or CAN bus nodes subjected to system-level ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Secondary clamp after primary gas discharge tube or polymer PTC, limiting residual voltage to transceiver tolerance. Use Value: 103 V clamping voltage stays below absolute maximum ratings of ISO 11898-2 compliant transceivers (typically 120 V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA (Bourns) | Same 75V nominal, 600W rating, but SMB package (surface-mount); lower thermal resistance than DO-15 | Preferred for automated SMT assembly; requires PCB rework for through-hole legacy designs | Select SMBJ75CA when board space is constrained and reflow compatibility is required |
| 1.5KE75CA (ON Semiconductor) | Identical DO-204AC package and electrical specs; same 75V/103V/600W profile; RoHS-compliant variant available | No functional or mechanical difference - direct second-source option with alternate supply chain | Choose 1.5KE75CA for dual-sourcing assurance without design or layout changes |
Compared with SMBJ75CA and 1.5KE75CA, the P6KE75CA offers identical surge performance in the legacy DO-15 through-hole format, making it ideal for repair, legacy industrial equipment, and prototyping where manual assembly or socketing is preferred - while 1.5KE75CA provides drop-in supply-chain redundancy and SMBJ75CA enables miniaturized SMT deployment.

FAQ
What is the clamping voltage of P6KE75CA at its rated peak pulse current?
The P6KE75CA has a maximum clamping voltage (VC) of 103 V at 6.1 A peak pulse current (IPP), measured under the standard 10/1000μs waveform. This value ensures protected circuits remain within safe operating limits during surge events. The P6KE75CA achieves this clamping performance while maintaining low dynamic impedance and fast 5.0ns response time.
Is P6KE75CA suitable for automotive applications?
Yes, P6KE75CA is AEC-Q101 qualified (as indicated by the "H" suffix in ordering code P6KE75CAH), confirming compliance with stress tests for temperature cycling, humidity bias, and mechanical shock required for automotive under-hood and body electronics. The P6KE75CA operates reliably from –55°C to +175°C and meets ISO 7637-2 pulse immunity requirements when applied per recommended layout guidelines.
How does P6KE75CA differ from unidirectional P6KE75A?
P6KE75CA is bidirectional with symmetrical breakdown in both polarities, while P6KE75A is unidirectional and requires correct cathode orientation. The P6KE75CA has identical VBR (71.3–78.8 V), VWM (64.1 V), and VC (103 V) ratings but supports AC-coupled or floating signal paths without polarity constraints - making the P6KE75CA ideal for RS-485, CAN, and transformer-isolated interfaces.
What is the maximum steady-state power dissipation for P6KE75CA?
The P6KE75CA has a steady-state power dissipation (PD) of 5 W at TA = 75°C when mounted on 5 × 5 mm copper pads per lead. This rating assumes proper PCB thermal relief and is distinct from its 600W non-repetitive surge capability. Continuous power handling must be derated above 75°C using the published pulse derating curve - critical for thermal design validation of the P6KE75CA in enclosed enclosures.
Does P6KE75CA meet RoHS and halogen-free standards?
Yes, P6KE75CA is RoHS compliant and halogen-free per IEC 61249-2-21, with pure tin-plated leads and UL 94V-0 molded compound. These material specifications are verified in TSC's manufacturing documentation and supported by certificate of compliance. The P6KE75CA satisfies environmental requirements for consumer, industrial, and automotive end equipment sold in EU, China, and other regulated markets.
