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 (342 V) and VC (548 V), but SMC package (DO-214AB); 600 W rating, lower RθJA (50 °C/W) due to surface-mount thermal path. | Better suited for high-density PCBs where through-hole real estate is constrained; requires reflow instead of wave solder. | Select SMBJ400CA when board space is limited and automated assembly is used; verify pad thermal relief for 175 °C operation. |
| 1.5KE400CA | Identical electrical specs (VWM, VBR, VC, PPPM), but larger DO-201AD package; higher IFSM (200 A vs. 100 A) and RθJL = 10 °C/W. | Preferred for high-energy surge environments (e.g., utility metering) where thermal mass and surge margin outweigh size concerns. | Choose 1.5KE400CA for applications demanding higher single-pulse robustness or extended thermal endurance beyond P6KE400C-E3/54 limits. |
Compared with SMBJ400CA and 1.5KE400CA, the P6KE400C-E3/54 offers optimal balance of cost, legacy through-hole compatibility, and proven field reliability in automotive and industrial control - especially where UL 497B recognition and AEC-Q101 process alignment are valued.

FAQ
What does the "C" suffix indicate in P6KE400C-E3/54?
The "C" in P6KE400C-E3/54 denotes bi-directional configuration - meaning the device provides symmetrical transient suppression for AC-coupled or polarity-agnostic signal lines. Unlike uni-directional variants (e.g., P6KE400A), the P6KE400C-E3/54 has no cathode marking and conducts identically in both directions above its 440 V minimum breakdown voltage. This makes P6KE400C-E3/54 ideal for protecting differential buses like RS-485 or transformer-coupled Ethernet interfaces.
Is P6KE400C-E3/54 AEC-Q101 qualified?
No - P6KE400C-E3/54 carries the "E3" suffix, indicating RoHS-compliant commercial grade per JESD 201 Class 1A whisker testing. The AEC-Q101 qualified version is designated P6KE400CHE3/54 (with "H" prefix). While both share identical die and electrical specs, only the HE3 variant undergoes full automotive stress qualification including temperature cycling, HTRB, and ESD testing per AEC-Q101 Rev D. For non-automotive industrial use, P6KE400C-E3/54 delivers equivalent protection performance.
What is the maximum clamping voltage of P6KE400C-E3/54 and under what test condition?
The maximum clamping voltage of P6KE400C-E3/54 is 548 V, measured at 1.1 A peak pulse current (IPPM) using the standard 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value represents the upper limit of voltage imposed on protected circuitry during a worst-case surge event and is guaranteed across the full operating temperature range (–55 °C to +175 °C). The clamping behavior is consistent in both directions due to the bi-directional structure of P6KE400C-E3/54.
Can P6KE400C-E3/54 be used in place of P6KE400A-E3/54?
No - P6KE400C-E3/54 and P6KE400A-E3/54 are not interchangeable without circuit review. P6KE400A-E3/54 is uni-directional with a cathode band and forward voltage drop (~5.0 V at 50 A), while P6KE400C-E3/54 is bi-directional with no polarity marking and symmetrical clamping. Substituting P6KE400C-E3/54 for P6KE400A-E3/54 on DC-biased lines may cause unintended conduction; conversely, using P6KE400A-E3/54 on AC lines risks incomplete protection during negative half-cycles. Always match polarity type to circuit topology when selecting P6KE400C-E3/54.
What is the thermal resistance specification for P6KE400C-E3/54 and how does it affect layout?
P6KE400C-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W, measured with 0.375" (9.5 mm) lead length per JEDEC standards. To maintain safe operation near its 175 °C maximum junction temperature, PCB layout must provide adequate copper area on both leads - ideally ≥100 mm² per lead - and avoid excessive trace length or narrow traces that increase thermal impedance. These values directly inform derating curves in Figure 2 of the Vishay datasheet for P6KE400C-E3/54.
