Product details
Overview
P6KE10CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust ESD and surge protection in automotive-grade power and signal lines. It features a 10V nominal breakdown voltage (VBR min/max: 9.0–11.0V), 8.1V stand-off voltage (VWM), clamping voltage of 15.0V at 42A peak surge current, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the P6KE10CAH datasheet, P6KE10CAH pinout, P6KE10CAH application, or P6KE10CAH equivalent, key selection criteria include its bidirectional DO-15 package, 15.0V clamping performance at 42A (10/1000μs), <1μA leakage above 10V, and AEC-Q101 qualification - critical for automotive infotainment power rails, CAN transceiver I/O protection, and industrial sensor interface hardening.
Technical Context
The P6KE10CAH operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior, enabling protection against both positive and negative transients without polarity dependency. Its low dynamic impedance and sub-nanosecond response time (<5.0ns from 0V to VBR) ensure rapid voltage limiting during fast electrical fast transients (EFT) and ISO 7637-2 pulse 1/2/5a events.
Thermally rated for junction temperatures from –55°C to +175°C and mounted on 5×5 mm copper pads, it sustains 600W non-repetitive peak pulse power (10/1000μs) with derating above 25°C ambient. The device uses a single-die DO-204AC (DO-15) package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.1 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC bias margin for protected line. |
| VBR (min/max) | 9.0 / 11.0 V - Breakdown occurs within this range at 1 mA test current; ensures predictable clamping onset across temperature and unit variation. |
| VC @ IPP | 15.0 V at 42 A - Clamped voltage during 10/1000μs surge; directly limits stress on downstream ICs like microcontrollers or transceivers. |
| PPK | 600 W - Peak pulse power handling per 10/1000μs waveform; supports high-energy surges common in automotive load dump or inductive switching. |
| IR @ VWM | <1 μA - Reverse leakage at 8.1 V; negligible power loss and minimal impact on high-impedance sensor or reference circuits. |
| TJ max | +175 °C - Maximum junction temperature; enables placement near hot components (e.g., power MOSFETs, engine control units) without thermal derating concerns. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with 0.400 g mass; compatible with legacy through-hole assembly and automated tape-and-reel (3500/reel). |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case meeting UL 94V-0 flammability rating; cathode band not applicable (bidirectional configuration).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No polarity marking required; either lead functions identically as input/output for transient suppression in AC or dual-polarity DC paths. |
| Lead 1 | Terminal connection | Pure tin-plated, solderable per J-STD-002; supports wave, reflow, and hand-soldering with verified wetting and intermetallic formation. |
| Lead 2 | Terminal connection | Identical to Lead 1; symmetric construction eliminates orientation constraints during PCB layout and assembly. |
Key Features

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 | Same 10V VBR and bidirectional DO-214AA package, but lower 600W PPK rating achieved at 1mm² smaller footprint; higher thermal resistance (RθJA = 50°C/W vs. DO-15's 40°C/W). | Better suited for space-constrained PCBs where board area is premium, but requires enhanced copper pour for equivalent thermal performance. | Select SMBJ10CA when layout density outweighs thermal margin needs and AEC-Q101 is not mandatory. |
| 1.5KE10CA | Same DO-201AE package and 10V rating, but rated for 1500W PPK (10/1000μs); larger die size increases capacitance (≈150 pF vs. P6KE10CAH's ≈100 pF) and cost. | Preferred for high-energy environments (e.g., heavy equipment battery systems) where 600W is insufficient, but may degrade high-frequency signal integrity. | Choose 1.5KE10CA only if surge threat level exceeds ISO 7637-2 Pulse 5b or IEC 61000-4-5 Level 4 compliance is required. |
Compared with SMBJ10CA and 1.5KE10CA, the P6KE10CAH uniquely balances AEC-Q101 qualification, DO-15 manufacturability, and 600W protection in a thermally robust through-hole format - making it optimal for automotive production modules requiring long-term supply stability and legacy assembly compatibility.

FAQ
What does the "CAH" suffix indicate in P6KE10CAH?
The "CA" denotes bidirectional configuration (common-anode equivalent for symmetrical clamping), and "H" signifies AEC-Q101 qualification per Version P2203 documentation. This confirms P6KE10CAH has undergone automotive-grade stress testing including temperature cycling, highly accelerated life testing, and ESD verification - distinguishing it from standard P6KE10CA variants.
Is P6KE10CAH suitable for protecting CAN FD physical layer circuits?
Yes, P6KE10CAH is appropriate for CAN FD protection due to its <5.0ns response time, 15.0V clamping voltage at 42A, and bidirectional symmetry - all critical for preserving signal edge integrity at 5 Mbps. Its low leakage (<1μA) avoids loading the 120Ω bus termination, and DO-15 footprint allows straightforward placement adjacent to transceiver pins without compromising layout symmetry.
How does P6KE10CAH perform under elevated ambient temperatures?
P6KE10CAH maintains full 600W surge capability at 25°C ambient, with linear derating per Figure 2 in the datasheet: at 75°C, it sustains ~450W; at 125°C, ~225W. Its 175°C maximum junction temperature and DO-15 thermal resistance (~40°C/W on 5×5 mm copper pads) enable reliable operation in under-hood environments when properly heatsinked.
Can P6KE10CAH replace P6KE10A in existing designs?
No - P6KE10A is unidirectional with cathode band marking and different VBR (9.5–10.5V), while P6KE10CAH is bidirectional (no polarity marking) with wider VBR (9.0–11.0V). Substituting them risks incorrect clamping behavior on AC-coupled or dual-polarity lines; PCB layout and schematic symbols must be updated to reflect symmetrical terminal assignment.
What is the typical junction capacitance of P6KE10CAH at 0V bias?
Per Figure 5 in the P6KE Series datasheet, P6KE10CAH exhibits approximately 100 pF junction capacitance at 0V bias and 1 MHz test frequency. This value decreases with increasing reverse bias - e.g., ~50 pF at VR = 8.1V - making it suitable for low-to-medium speed data lines but not recommended for >100 Mbps interfaces without signal integrity analysis.
