Product details
Overview
P6KE6.8CA-E3/73 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 breakdown voltage (VBR), 10.5 V maximum clamping voltage (VC) at 57.1 A peak pulse current, 600 W peak pulse power (10/1000 μs), and operates from –55 °C to +175 °C - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE6.8CA-E3/73 datasheet, P6KE6.8CA-E3/73 pinout, P6KE6.8CA-E3/73 application, or P6KE6.8CA-E3/73 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, DO-15 mechanical data, thermal resistance (RθJL = 20 °C/W), and AEC-Q101 qualification status - all critical for ESD/surge design validation and automotive-grade component selection.
Technical Context
This device implements a glass-passivated silicon avalanche junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional structure enables symmetrical clamping in AC-coupled or floating signal paths without polarity concerns.
It delivers 600 W peak pulse power under standardized 10/1000 μs waveform with 0.01% duty cycle, and maintains stable clamping performance across –55 °C to +175 °C junction temperature range - validated per AEC-Q101 stress tests including HTRB, HTGB, and temperature cycling.

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 | DO-214AA package, 600 W rating, VC = 11.2 V @ 53.5 A - slightly higher clamping voltage and lower thermal resistance (RθJL = 15 °C/W) | Preferred where board space allows SMC/SMB footprint and higher power density is needed | Select SMBJ6.8CA when layout permits surface-mount and thermal management uses larger copper areas |
| 1.5KE6.8CA | DO-201AD package, 1500 W rating, VC = 10.5 V @ 143 A - higher surge capacity but larger axial package and higher RθJA | Suitable for high-energy industrial mains input stages where DO-15 power margin is insufficient | Choose 1.5KE6.8CA only when system-level surge testing requires >600 W capability and axial mounting is acceptable |
Compared with SMBJ6.8CA and 1.5KE6.8CA, P6KE6.8CA-E3/73 offers optimal balance of compact DO-15 form factor, AEC-Q101 qualification, and precise 10.5 V clamping - making it preferred for space-constrained automotive and industrial control modules requiring production traceability and automotive-grade reliability.

FAQ
What is the breakdown voltage tolerance for P6KE6.8CA-E3/73?
The P6KE6.8CA-E3/73 has a specified breakdown voltage (VBR) range of 6.45 V to 7.14 V at 10 mA test current, representing ±5% tolerance around the nominal 6.8 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports predictable system-level surge margin calculations in designs using P6KE6.8CA-E3/73.
Is P6KE6.8CA-E3/73 suitable for automotive applications?
Yes, P6KE6.8CA-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use in engine control units, body electronics, and ADAS sensor interfaces. Its –55 °C to +175 °C operating range, glass-passivated junction, and validated stress test performance (HTRB, HTGB, temperature cycling) make P6KE6.8CA-E3/73 appropriate for under-hood and cabin-mounted modules requiring automotive-grade reliability.
Does P6KE6.8CA-E3/73 have polarity markings?
No, P6KE6.8CA-E3/73 is a bidirectional TVS diode and carries no cathode band or polarity marking - both leads are functionally identical. This symmetry allows direct placement across AC-coupled lines or floating differential pairs without orientation concerns, simplifying assembly and eliminating risk of reverse installation in circuits protected by P6KE6.8CA-E3/73.
What is the maximum clamping voltage of P6KE6.8CA-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P6KE6.8CA-E3/73 is 10.5 V at 57.1 A peak pulse current (10/1000 μs waveform). This value represents the highest voltage imposed on the protected circuit during worst-case transient events, and is a key parameter for ensuring downstream components like 5 V microcontrollers or CAN transceivers remain within safe operating limits when P6KE6.8CA-E3/73 is deployed.
How does P6KE6.8CA-E3/73 differ from unidirectional P6KE6.8A-E3/73?
P6KE6.8CA-E3/73 is bidirectional with symmetrical clamping in both polarities and no cathode marking, while P6KE6.8A-E3/73 is unidirectional with a cathode band and conducts only in reverse bias. The "CA" suffix denotes bidirectional functionality - critical for AC signal lines or floating interfaces where polarity reversal may occur. Both share identical VBR, VC, and PPPM, but P6KE6.8CA-E3/73 must be used where bidirectional protection is required.
