Product details
Overview
P6KE10CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 10 V, clamps transients to ≤15.0 V at 42 A peak surge current, and delivers sub-5 ns response time with <1 μA reverse leakage above 8.1 V stand-off voltage - deployed in automotive lighting control modules and industrial I/O interfaces.
For engineers reviewing the P6KE10CA datasheet, P6KE10CA pinout, P6KE10CA application, or P6KE10CA equivalent, key selection criteria include its bidirectional DO-15 package, 10/1000 µs waveform surge rating, AEC-Q101 qualification (H-grade variant), and compatibility with ESD/EFM/inductive-switching transient immunity requirements per IEC 61000-4-2/4-4/4-5.
Technical Context
The P6KE10CA operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior - both anodes tied internally to form a center-tapped configuration enabling equal forward/reverse breakdown characteristics. Its low dynamic impedance (<1 Ω typical) ensures rapid voltage limiting during fast-rising transients up to 1000 V/µs.
Thermal design relies on junction-to-ambient conduction through axial leads mounted on 5×5 mm copper pads; derating begins above 25°C ambient, with maximum junction temperature rated at +175°C and storage range from –55°C to +175°C. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W at 10/1000 µs waveform - sustains single high-energy surges without failure in automotive load-dump or inductive kick scenarios |
| Breakdown Voltage VBR | 9.0–11.0 V at 1 mA test current - defines precise clamping onset threshold for bidirectional overvoltage events |
| Stand-Off Voltage VWM | 8.1 V maximum - ensures reliable blocking of normal operating voltages while remaining below breakdown |
| Clamping Voltage VC | ≤15.0 V at 42 A IPP - limits downstream circuit stress to safe levels during worst-case transient conditions |
| Response Time | <5.0 ns - enables effective suppression of ESD and electrical fast transients before sensitive ICs are damaged |
| Junction Temperature Range | –55°C to +175°C - supports operation in under-hood automotive and industrial environments |
| Leakage Current ID | <1 µA at 8.1 V - minimizes standby power loss and avoids false triggering in low-power systems |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking for unidirectional variants; P6KE10CA uses symmetric bidirectional construction - no polarity marking required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 / Cathode | Transient clamp terminal (bidirectional) | Acts as cathode in one polarity, anode in reverse - forms symmetrical clamping path across both directions |
| Anode 2 / Cathode | Transient clamp terminal (bidirectional) | Electrically identical to Pin 1 - internal center-tap configuration enables true bidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, lighting, and body electronics per stress-test requirements |
| Low clamping ratio (VC/VBR ≈ 1.5) | Minimizes overvoltage margin between breakdown and clamping - critical for protecting 3.3 V/5 V logic interfaces |
| UL 94V-0 flammability rating | Ensures flame-retardant encapsulation suitable for safety-critical PCB layouts in enclosed enclosures |
| Halogen-free per IEC 61249-2-21 | Complies with RoHS and environmental directives for green manufacturing and end-of-life disposal |
| Pure tin-plated leads | Enables lead-free reflow soldering per J-STD-002 and eliminates whisker growth risk in long-life deployments |

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 (Bourns) | 400 W peak power, SMB package (surface-mount), 10.0–11.1 V VBR range, 15.0 V VC at 27.3 A | Lower surge rating; suited for space-constrained PCBs where board area is prioritized over extreme energy handling | Select SMBJ10CA when footprint reduction and automated assembly outweigh need for 600 W capability. |
| 1.5KE10CA (ON Semiconductor) | Identical 600 W rating and DO-15 package; VBR 9.0–11.0 V, VC ≤15.0 V at 42 A, but not AEC-Q101 qualified | Lacks automotive qualification - acceptable for industrial/commercial use but not for automotive OEM designs | Choose 1.5KE10CA for cost-sensitive non-automotive applications requiring same electrical performance without AEC-Q101 validation. |
Compared with SMBJ10CA and 1.5KE10CA, the P6KE10CA uniquely combines AEC-Q101 qualification, 600 W surge capacity, and DO-15 through-hole robustness - making it optimal for automotive front-end protection where reliability under thermal cycling and mechanical vibration is mandatory.

FAQ
What is the key difference between P6KE10CA and P6KE10A?
The P6KE10CA is a bidirectional TVS diode with symmetrical clamping in both polarities, while P6KE10A is unidirectional and requires correct polarity orientation during placement. The "CA" suffix explicitly denotes bidirectional functionality per TSC's ordering convention - critical for AC-coupled or floating signal line protection where voltage polarity reverses.
Does P6KE10CA meet AEC-Q101 qualification?
Yes, P6KE10CA is AEC-Q101 qualified when ordered with the "H" suffix (e.g., P6KE10CAH). The base P6KE10CA part number may be supplied in standard or AEC-Q101 grades depending on packaging code; confirmation requires verifying the full ordering code and associated certificate from Taiwan Semiconductor's official documentation.
What is the maximum clamping voltage of P6KE10CA at rated surge current?
The P6KE10CA has a maximum clamping voltage (VC) of 15.0 V at 42 A peak pulse current (IPP), measured under the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Can P6KE10CA be used in place of a unidirectional TVS like P6KE10C?
No - P6KE10CA cannot substitute for unidirectional parts such as P6KE10C in circuits requiring asymmetric protection (e.g., DC rail with defined ground reference), because its bidirectional structure conducts in both directions. Using it in place of a unidirectional TVS may cause unintended conduction or fail to block reverse leakage in certain topologies.
What is the junction capacitance of P6KE10CA at zero bias?
The P6KE10CA exhibits a typical junction capacitance (CJ) of approximately 1000 pF at 0 V bias and 1 MHz, as shown in TSC's Fig.5 characteristic curve. This relatively high capacitance makes it unsuitable for high-speed data lines but appropriate for power rail and low-frequency signal protection where bandwidth is not critical.
