Product details
Overview
P6KE6.8CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 6.8 V nominal breakdown voltage (VBR), 10.5 V maximum clamping voltage (VC) at 57.1 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE6.8CA-E3/54 datasheet, P6KE6.8CA-E3/54 pinout, P6KE6.8CA-E3/54 application, or P6KE6.8CA-E3/54 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, DO-15 mechanical dimensions, AEC-Q101 qualification status, and real-world protection use cases - all confirmed from Vishay's official document #88369 (Rev. 27-Sep-2021).
Technical Context
This device operates as a voltage-clamping surge 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 across -55 °C to +175 °C junction temperature range.
It complies with UL 497B (QVGQ2 recognition) and meets JESD 22-B106 solderability (275 °C, 10 s). The 600 W peak pulse power is rated under 0.01 % duty cycle, with thermal resistance RθJL = 20 °C/W enabling effective lead-based heat dissipation during transient events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA test current - defines reliable turn-on threshold for overvoltage detection |
| VWM | 5.80 V - maximum continuous reverse working voltage before leakage exceeds 1000 μA |
| VC @ IPPM | 10.5 V at 57.1 A - clamped voltage seen by protected circuit during worst-case 10/1000 μs surge |
| PPPM | 600 W - peak transient energy absorption capability without failure under standardized waveform |
| IPPM | 57.1 A - maximum non-repetitive surge current the device safely diverts away from downstream components |
| TJ max | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional symmetry eliminates cathode/anode orientation concerns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path terminal | Either end conducts identically during positive or negative surges - no directional installation required |
| Lead 1 / Lead 2 | Thermal and electrical interface | Leads serve as primary heat sink path (RθJL = 20 °C/W); length ≥ 9.5 mm required for full power derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.8CA | Same VBR (6.45–7.14 V) and VC (10.5 V), but SMC package (higher IPPM = 64.1 A, PPPM = 600 W) | Surface-mount footprint; better suited for automated assembly and higher-density PCB layouts | Select SMBJ6.8CA when board space is constrained and reflow compatibility is required |
| 1.5KE6.8CA | Same DO-15 package and VBR, but higher PPPM = 1500 W and VC = 11.2 V at 133 A | Higher-energy surge handling; used where IEC 61000-4-5 Level 5 (6 kV) immunity is mandated | Choose 1.5KE6.8CA when protecting against more severe transients, accepting slightly higher clamping voltage |
Compared with SMBJ6.8CA and 1.5KE6.8CA, P6KE6.8CA-E3/54 offers optimal balance of cost, through-hole manufacturability, and 600 W surge capacity - making it ideal for mid-tier industrial and automotive modules where AEC-Q101 compliance and UL recognition are mandatory but extreme energy levels are not expected.

FAQ
What is the breakdown voltage tolerance for P6KE6.8CA-E3/54?
The P6KE6.8CA-E3/54 has a guaranteed breakdown voltage range of 6.45 V to 7.14 V at 10 mA test current, corresponding to ±10 % tolerance around the nominal 6.8 V rating. This tight VBR window ensures consistent clamping onset across production lots and temperature extremes, critical for predictable protection in 5 V rail applications.
Is P6KE6.8CA-E3/54 suitable for automotive applications?
Yes, P6KE6.8CA-E3/54 is AEC-Q101 qualified and explicitly listed in Vishay's documentation as meeting automotive reliability requirements. Its -55 °C to +175 °C operating range, glass-passivated junction, and UL 497B recognition make it appropriate for engine control units, body control modules, and ADAS sensor interfaces where transient immunity is essential.
How does the clamping voltage of P6KE6.8CA-E3/54 compare to its breakdown voltage?
P6KE6.8CA-E3/54 clamps to a maximum of 10.5 V at 57.1 A peak pulse current, yielding a clamping ratio (VC/VBR) of approximately 1.55. This low ratio ensures minimal overvoltage stress on protected 5 V or 3.3 V circuits - significantly tighter than many competing TVS diodes with ratios >1.8 - preserving downstream IC functionality during surge events.
What is the maximum surge current P6KE6.8CA-E3/54 can handle?
P6KE6.8CA-E3/54 supports a peak pulse current (IPPM) of 57.1 A under the standard 10/1000 μs waveform. This value is derived directly from its 600 W peak pulse power rating and 10.5 V clamping voltage (I = P/V). It is not rated for repetitive surges beyond 0.01 % duty cycle, and derating applies above 25 °C ambient per Vishay's Fig. 2.
Does P6KE6.8CA-E3/54 require polarity-aware PCB layout?
No - P6KE6.8CA-E3/54 is a bidirectional TVS diode (denoted by "CA" suffix), meaning both terminals are functionally identical and exhibit symmetric clamping behavior for positive and negative transients. There is no cathode band or polarity marking; either lead may connect to line or ground without affecting protection performance.
