Product details
Overview
P4KE10CA from Taiwan Semiconductor is a bidirectional 400W transient voltage suppressor (TVS) diode designed for high-energy ESD and surge protection in DC power rails and signal lines. It features a 10V nominal standoff voltage, 9.0–11.0V breakdown range at 1mA test current, 15.0V maximum clamping voltage at 28A peak pulse current, and DO-204AL (DO-41) axial package - deployed in automotive lighting control modules to protect CAN transceiver inputs against ISO 7637-2 load dump transients.
For engineers reviewing the P4KE10CA datasheet, P4KE10CA pinout, P4KE10CA application, or P4KE10CA equivalent, key selection criteria include bidirectional clamping capability, 15.0V VC@28A performance under 10/1000μs waveform, AEC-Q101 qualification status, low leakage (<1μA @ 8.1V), and thermal stability up to +175°C junction temperature.
Technical Context
The P4KE10CA operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior - enabling identical VBR, VC, and ID specifications in both polarities. Its 10/1000μs surge rating of 400W defines energy-handling capacity for automotive-level transients including ISO 16750-2 pulses and IEC 61000-4-5 combination wave surges.
With a typical response time of 5.0ns (bidirectional), it reacts faster than most MOVs and polymer-based protectors, ensuring sub-microsecond clamping onset. The device's temperature coefficient of 0.073%/°C for VBR ensures predictable voltage drift across its –55°C to +175°C operating range, critical for under-hood electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 10V - defines rated working stand-off level before conduction begins in either polarity |
| Breakdown Voltage VBR | 9.0–11.0V @ 1mA - verified avalanche initiation threshold; ensures reliable turn-on before system damage |
| Clamping Voltage VC | 15.0V @ 28A (10/1000μs) - maximum voltage seen by protected IC during full-rated surge event |
| Peak Pulse Power | 400W - sustains single 10/1000μs transient without degradation; derates linearly above 25°C ambient |
| Reverse Leakage ID | <1μA @ 8.1V - negligible standby current; avoids battery drain in always-on automotive circuits |
| Junction Temperature | –55°C to +175°C - supports placement near heat sources (e.g., engine control units, LED drivers) |
| Package | DO-204AL (DO-41) - industry-standard axial leaded package compatible with through-hole assembly and manual repair |
Pinout & Package
DO-204AL (DO-41) axial package with non-polarized construction: two leads with no anode/cathode marking required for bidirectional operation. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either lead serves as input/output terminal; no polarity sensitivity - simplifies PCB layout and orientation |
| Lead 1 / Lead 2 | Current path for surge conduction | Carries full IPPM (28A) during clamping; requires ≥0.375" (9.5mm) copper pad per lead for thermal dissipation at TL = 75°C |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HAST, and mechanical shock - suitable for front-end power protection in ADAS ECUs |
| 400W 10/1000μs surge rating | Withstands ISO 7637-2 Pulse 5a (load dump) up to 60V/100ms without failure - eliminates need for external series impedance in many 12V systems |
| 5.0ns bidirectional response | Clamps within 5 nanoseconds of transient onset - protects high-speed interfaces (e.g., LIN, CAN FD) before voltage overshoot damages transceivers |
| UL 94V-0 molding compound | Self-extinguishing encapsulation meets automotive flammability requirements - approved under UL File #E-326243 |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - supports green manufacturing and end-of-life recycling compliance |

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 SMAJ10CA | Same DO-214AC (SMA) package; 15.0V [email protected]; slightly higher IR (≤5μA @ 8.1V) | Surface-mount only - requires rework of PCB layout; better high-frequency ESD performance due to lower parasitic inductance | Select when board space is constrained and SMT assembly is preferred; verify thermal pad design for 400W pulse handling |
| Vishay 1.5KE10CA | Higher 1500W peak power rating; same DO-204AL package; 15.0V VC@100A; larger physical size (DO-201AD) | Over-specified for 400W use cases - adds cost and board area without benefit unless legacy 1.5kW surge margin is mandated | Choose only if system-level testing requires >400W margin or if existing BOM already uses 1.5KE family for logistics consolidation |
Compared with SMAJ10CA and 1.5KE10CA, the P4KE10CA delivers optimal balance of through-hole manufacturability, AEC-Q101 qualification, and precise 400W/15.0V clamping - making it ideal for cost-sensitive, high-volume automotive and industrial power rail protection where DO-41 compatibility and thermal robustness are prioritized.

FAQ
What is the maximum clamping voltage of the P4KE10CA under standard surge conditions?
The P4KE10CA has a maximum clamping voltage (VC) of 15.0V when subjected to a 10/1000μs waveform with a peak pulse current (IPPM) of 28A. This value is measured per ANSI/IEEE C62.35 standards and represents the highest voltage the protected circuit will experience during a full-rated 400W transient event. The P4KE10CA maintains this clamping performance consistently across its operating temperature range.
Is the P4KE10CA suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the P4KE10CA is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's documentation and UL recognition file #E-326243. It undergoes rigorous stress testing including temperature cycling, highly accelerated stress testing (HAST), and mechanical shock, making it suitable for under-hood and chassis-mounted automotive electronics such as body control modules and lighting drivers where reliability under harsh environmental conditions is mandatory.
How does the bidirectional configuration of the P4KE10CA affect its circuit implementation?
The P4KE10CA is inherently bidirectional, meaning it provides symmetrical clamping in both polarities without requiring specific anode/cathode orientation. This eliminates polarity marking on the DO-204AL package and allows flexible placement across any DC rail or AC-coupled signal line. Unlike unidirectional TVS diodes, the P4KE10CA does not require series blocking diodes or careful PCB routing to avoid reverse bias failure - simplifying design and reducing bill-of-materials count.
What is the thermal derating behavior of the P4KE10CA above 25°C ambient temperature?
The P4KE10CA's peak pulse power rating of 400W is specified at TA = 25°C and derates linearly above that temperature, following the curve in Figure 2 of the official datasheet. At 75°C ambient, its steady-state power dissipation is rated at 1W with 0.375" copper pads per lead. For pulsed operation, derating must be applied per the published derating curve to ensure junction temperature remains ≤175°C - critical for sustained reliability in high-temperature environments like engine compartments.
Can the P4KE10CA replace the P4KE10A in an existing design?
No - the P4KE10CA and P4KE10A are not interchangeable. The "CA" suffix denotes bidirectional operation, while "A" indicates unidirectional with cathode band marking. Substituting P4KE10CA for P4KE10A would eliminate polarity-dependent forward conduction and alter clamping symmetry, potentially causing malfunction in circuits relying on DC blocking or directional surge routing. Always verify directionality requirements before replacement.
