Product details
Overview
P6KE400CA-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 400 V standoff voltage (VWM), 459 V minimum breakdown voltage (VBR), 548 V maximum clamping voltage at 1.1 A peak pulse current, 600 W peak pulse power rating (10/1000 μs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive sensor interfaces and industrial motor drive control circuits.
For engineers reviewing the P6KE400CA-E3/73 datasheet, P6KE400CA-E3/73 pinout, P6KE400CA-E3/73 application, or P6KE400CA-E3/73 equivalent, this page delivers verified electrical parameters, DO-15 package details, bidirectional clamping behavior, thermal derating curves, and AEC-Q101-qualified alternatives for ESD and lightning surge protection design validation.
Technical Context
The P6KE400CA-E3/73 uses a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional architecture enables symmetrical clamping in both polarities without polarity marking, supporting AC-coupled lines and differential bus protection.
It complies with AEC-Q101 for automotive-grade reliability and meets UL 497B recognition (QVGQ2). The device sustains 600 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle, with thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient).
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ400CA | DO-214AA package; 600 W rating; lower VC = 533 V at 1.12 A; higher IPPM | Suitable for space-constrained SMT layouts; requires rework of footprint and thermal relief | Select when board area is limited and reflow compatibility is prioritized over through-hole serviceability |
| 1.5KE400CA | Higher 1500 W rating; same DO-15 package; VC = 590 V at 2.55 A; larger case diameter (3.6 mm vs. 2.7 mm) | Used where single-event surge energy exceeds 600 W but PCB lead pitch remains unchanged | Choose for enhanced margin against rare high-energy transients without altering mounting hole pattern |

FAQ
What is the clamping voltage of P6KE400CA-E3/73 under standard 10/1000 μs surge conditions?
The P6KE400CA-E3/73 has a maximum clamping voltage (VC) of 548 V at 1.1 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88369 and ensures predictable overvoltage limiting for downstream components such as CAN transceivers or microcontroller I/O pins. The P6KE400CA-E3/73 maintains this clamping performance across its full operating temperature range.
Is P6KE400CA-E3/73 qualified for automotive use?
Yes, the P6KE400CA-E3/73 is AEC-Q101 qualified, as confirmed in the "Notes" section of Vishay document 88369 (Revision: 27-Sep-2021). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for under-hood and chassis-mounted automotive electronics. The P6KE400CA-E3/73 carries the HE3 suffix variant for full AEC-Q101 compliance; the E3/73 version is RoHS-compliant commercial grade with identical electrical specs.
How does the bidirectional configuration of P6KE400CA-E3/73 affect circuit layout?
The P6KE400CA-E3/73 has no polarity marking - its bidirectional structure allows installation in either orientation across AC-coupled or differential signal paths without functional impact. Unlike unidirectional TVS diodes, the P6KE400CA-E3/73 eliminates risk of reverse installation error and simplifies layout for balanced lines such as RS-485, CAN FD, or audio inputs. Its DO-15 package supports standard 0.375" lead spacing, enabling direct replacement in existing through-hole footprints.
What is the maximum reverse leakage current of P6KE400CA-E3/73 at rated standoff voltage?
At its rated standoff voltage (VWM) of 342 V, the P6KE400CA-E3/73 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C, as specified in Table "ELECTRICAL CHARACTERISTICS" on page 2 of Vishay document 88369. This ultra-low leakage preserves signal integrity in high-impedance sensor bias networks and minimizes standby power loss in battery-operated systems. The P6KE400CA-E3/73 maintains leakage below 5 μA up to 125 °C per thermal derating data.
Can P6KE400CA-E3/73 be used in parallel for higher surge current handling?
No - the P6KE400CA-E3/73 is not recommended for parallel operation due to inherent parameter variation (e.g., VBR tolerance ±5%) that causes current imbalance and premature failure of the unit with lowest breakdown voltage. For higher surge capability, Vishay specifies discrete higher-power alternatives like 1.5KE400CA (1500 W) or stacked TVS arrays. The P6KE400CA-E3/73 is characterized and tested as a single-device solution per its datasheet conditions.
