Product details
Overview
P6KE56CA A0G from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a nominal breakdown voltage of 56 V, clamps transients to ≤80.5 V at 7.8 A peak surge current, and delivers fast response (<5 ns) with low dynamic impedance. It is used in automotive lighting control modules and industrial PLC I/O protection circuits.
For engineers reviewing the P6KE56CA A0G datasheet, P6KE56CA A0G pinout, P6KE56CA A0G application, or P6KE56CA A0G equivalent, key selection criteria include bidirectional clamping capability, DO-15 package compatibility, 56 V standoff voltage margin, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
The P6KE56CA A0G implements a silicon avalanche diode structure optimized for unidirectional or bidirectional transient suppression. Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating systems without polarity sensitivity. The device operates within a -55°C to +175°C junction temperature range and maintains stable VBR with a temperature coefficient of 0.103 %/°C.
It meets ANSI/IEEE C62.35 standards for transient suppression and delivers 600 W non-repetitive peak pulse power under 10/1000 µs waveform. Clamping performance is validated at 7.8 A IPP, with VC ≤ 80.5 V - ensuring downstream ICs remain below absolute maximum ratings during ESD or load-dump events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 45.4 V - Maximum continuous reverse working voltage before leakage exceeds 1 µA; defines safe operating margin below breakdown. |
| VBR (min/max) | 50.4 V / 61.6 V at 1 mA - Verified breakdown threshold range ensures reliable turn-on across process variation and temperature. |
| VC @ IPP | 80.5 V at 7.8 A - Clamping voltage under 10/1000 µs surge; determines maximum stress on protected circuitry. |
| PPK | 600 W - Peak pulse power handling capacity; supports high-energy transients like ISO 7637-2 Load Dump Pulse 5a. |
| IR @ VWM | <1 µA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |
| TJMAX | +175 °C - Enables operation in under-hood automotive environments and high-temperature industrial enclosures. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with tin-plated leads compliant to J-STD-002 solderability. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded plastic case meeting UL 94V-0 flammability rating; cathode band marking indicates polarity for unidirectional variants - absent on P6KE56CA A0G due to bidirectional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No polarity dependency - either terminal serves as anode or cathode depending on transient polarity; enables single-device AC line protection. |
| Lead 1 | Terminal connection | Tin-plated copper lead, solderable per J-STD-002; supports wave, reflow, and hand-soldering with 0.4 g unit weight. |
| Lead 2 | Terminal connection | Identical to Lead 1; symmetric construction eliminates orientation constraints during PCB placement. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled or floating interfaces (e.g., RS-485, CAN bus stubs) without external polarity management. |
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics where reliability under thermal cycling and vibration is critical. |
| 600 W surge rating (10/1000 µs) | Withstands high-energy transients such as ISO 7637-2 Pulse 5a (load dump) up to 120 V, protecting downstream DC-DC converters and microcontrollers. |
| Clamping voltage ≤ 80.5 V | Ensures protected ICs with 85 V absolute maximum rating (e.g., automotive MCUs) remain within safe operating limits during surge events. |
| Low dynamic impedance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts), improving immunity to electrical fast transients per IEC 61000-4-4. |
Applications
| Automotive Lighting Control | Industrial PLC Digital I/O |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58CA | 600 W rating, 58 V nominal VBR, SMB package (surface-mount); lower thermal resistance but requires PCB real estate and reflow process. | Preferred for space-constrained designs where automated assembly is required; not suitable for through-hole legacy boards. | Select SMBJ58CA when board layout supports SMT and thermal management via copper pour is feasible. |
| 1.5KE56CA | Same DO-15 package and 56 V rating, but 1500 W peak power; larger die size increases capacitance (~100 pF vs. ~50 pF for P6KE56CA). | Better for high-energy threats (e.g., ISO 16750-2 Pulse 5b), but higher junction capacitance may degrade high-speed signal integrity. | Choose 1.5KE56CA only when surge threat level exceeds 600 W and signal bandwidth is below 10 MHz. |
Compared with SMBJ58CA and 1.5KE56CA, the P6KE56CA A0G offers optimal balance of through-hole manufacturability, 600 W protection level, low capacitance, and AEC-Q101 qualification - making it ideal for cost-sensitive, thermally moderate automotive and industrial applications requiring proven reliability without SMT conversion.

FAQ
What does the "CA" suffix indicate in P6KE56CA A0G?
The "CA" suffix denotes bidirectional configuration - meaning the P6KE56CA A0G functions identically in both polarities and has no anode/cathode distinction. This differs from unidirectional variants (e.g., P6KE56A), which require correct orientation on the PCB. The CA version is essential for AC-coupled or floating signal line protection where polarity reversal occurs.
Is P6KE56CA A0G AEC-Q101 qualified?
Yes, P6KE56CA A0G is AEC-Q101 qualified, as confirmed by Taiwan Semiconductor's ordering code documentation (P6KEx A0G with "x" ≥ 10 V and excluding early low-voltage variants). This qualification covers stress tests including temperature cycling, mechanical shock, and high-temperature operating life - validating its suitability for automotive under-hood and chassis applications.
What is the maximum clamping voltage of P6KE56CA A0G under surge conditions?
The maximum clamping voltage (VC) of P6KE56CA A0G is 80.5 V at 7.8 A peak pulse current (IPP) under the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage seen across the device during worst-case surge events, directly determining protection margin for downstream components.
How does P6KE56CA A0G differ from P6KE56A?
P6KE56CA A0G is bidirectional with symmetrical clamping in both directions, while P6KE56A is unidirectional and must be oriented with cathode toward the protected circuit's positive rail. The CA variant eliminates polarity concerns in AC or floating systems, whereas the A variant offers slightly tighter VBR tolerance (53.2–58.8 V vs. 50.4–61.6 V) and lower leakage at lower voltages.
What packaging format does P6KE56CA A0G ship in?
P6KE56CA A0G ships in ammo box packaging containing 1,500 units per box, as indicated by the "A0G" suffix in the ordering code. This format supports manual or semi-automated insertion processes and is distinct from tape-and-reel (3,500 units) used for SMT-compatible variants. Lead finish is pure tin, compliant with J-STD-002 solderability requirements.
