Product details
Overview
P6KE400CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on power and signal lines. It features 600 W peak pulse power (10/1000 μs), 342 V stand-off voltage (VWM), 380–420 V breakdown voltage (VBR), and clamps to ≤548 V at 1.1 A peak pulse current - used in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the P6KE400CA-E3/54 datasheet, P6KE400CA-E3/54 pinout, P6KE400CA-E3/54 application, or P6KE400CA-E3/54 equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, DO-15 mechanical data, thermal resistance (RθJA = 75 °C/W), and AEC-Q101 qualification status - critical for ESD/surge protection design validation.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical bidirectional conduction - no polarity marking required. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable clamping under repetitive 0.01% duty cycle transients.
Designed for unclamped transient energy absorption, it conducts only above VBR (min 380 V, max 420 V @ 1 mA), holds below VWM = 342 V with ≤1.0 μA leakage, and achieves full clamping at VC = 548 V under 1.1 A IPPM - validated per IEC 61000-4-5 surge waveform standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 342 V - maximum continuous reverse operating voltage before significant leakage; defines safe working margin below breakdown |
| VBR (min/max) | 380 V / 420 V @ 1 mA - guaranteed breakdown range ensures predictable turn-on across temperature and unit variation |
| VC @ IPPM | 548 V @ 1.1 A - clamping voltage during 10/1000 μs surge; determines protected circuit's maximum overvoltage exposure |
| PPPM | 600 W - peak pulse power handling capability; defines survivability against standardized lightning/surge events |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance; sets derating requirement for sustained power dissipation |
| TJ max. | +175 °C - maximum junction temperature; supports operation in under-hood automotive and high-ambient industrial environments |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, epoxy-molded case with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Both terminals function identically; conducts surge current in either direction once VBR exceeded |
| Lead 1 / Lead 2 | Thermal and electrical interface | Leads serve as primary heat sink path (RθJL = 20 °C/W); require ≥25.4 mm lead length for rated power derating |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables <1 ns response time and stable VBR tolerance across 1000+ surge cycles without parameter drift |
| 600 W peak pulse rating (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 (4 kV) surges on 50 Ω source impedance without degradation |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation meets flame-retardancy requirements for enclosed industrial and transportation systems |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; suitable for high-reliability automated assembly with no post-soldering inspection needed |
Applications
| Automotive Sensor Protection | Industrial Power Input Stage |

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 | Same VWM/VBR/VC ratings but SMC (DO-214AB) package; 600 W rating, lower RθJA (50 °C/W) | Better thermal performance in PCB-constrained layouts; requires rework of footprint and solder stencil | Select when higher power density or improved thermal management is required and board space permits SMC footprint |
| 1.5KE400CA | Same electrical specs but larger DO-201AD package; 1500 W peak pulse rating (10/1000 μs) | Higher surge margin for mission-critical infrastructure; 3× the physical volume and weight | Choose for applications requiring extended surge endurance beyond 600 W, such as utility metering or railway signaling |
Compared with SMBJ400CA and 1.5KE400CA, P6KE400CA-E3/54 offers optimal balance of cost, size, and AEC-Q101 qualification in the DO-15 form factor - making it preferred for space-constrained automotive and industrial modules where 600 W surge rating suffices.

FAQ
What is the clamping voltage of P6KE400CA-E3/54 under standard surge conditions?
The P6KE400CA-E3/54 clamps to a maximum of 548 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 1.1 A. This value is measured per IEC 61000-4-5 test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The P6KE400CA-E3/54 maintains this clamping performance across its full operating temperature range of –55 °C to +175 °C.
Is P6KE400CA-E3/54 suitable for automotive applications?
Yes, P6KE400CA-E3/54 is AEC-Q101 qualified and explicitly listed in Vishay's documentation as meeting automotive reliability requirements. Its DO-15 package, 175 °C maximum junction temperature, and robust surge performance make it appropriate for under-hood and cabin-mounted ECUs, sensor interfaces, and infotainment power rails. The P6KE400CA-E3/54 also complies with UL 94 V-0 flammability and JESD 201 Class 1A whisker resistance standards.
How does the bidirectional design of P6KE400CA-E3/54 affect circuit layout?
The bidirectional nature of P6KE400CA-E3/54 eliminates polarity marking and orientation constraints - both leads are functionally identical, simplifying PCB layout and automated placement. Unlike unidirectional TVS diodes, P6KE400CA-E3/54 requires no attention to cathode band alignment, reducing assembly errors and enabling symmetric placement across differential lines or AC-coupled paths. This symmetry is confirmed by identical VBR and VC values in both directions.
What is the thermal resistance profile of P6KE400CA-E3/54, and how does it impact derating?
P6KE400CA-E3/54 has a junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. At ambient temperatures above 25 °C, its 5.0 W steady-state power dissipation must be linearly derated per Vishay's Fig. 5 curve - for example, at 75 °C ambient, maximum continuous power drops to ~2.5 W. Proper lead length (≥25.4 mm) and copper pour area are essential to achieve published thermal performance. The P6KE400CA-E3/54 datasheet provides exact derating multipliers versus temperature.
Can P6KE400CA-E3/54 replace P6KE440CA in an existing design?
No - P6KE400CA-E3/54 and P6KE440CA have different breakdown and clamping characteristics: P6KE400CA-E3/54 specifies VBR = 380–420 V and VC = 548 V, whereas P6KE440CA has VBR = 418–462 V and VC = 602 V. Substituting P6KE400CA-E3/54 would lower clamping headroom and risk overvoltage stress on downstream components if the original design relied on the higher threshold. The P6KE400CA-E3/54 is not a drop-in replacement for P6KE440CA without circuit revalidation.
