What is the difference between P6KE6.8A and P6KE6.8CA?

Time：2026-07-22 Views：22次
Share：

P6KE6.8A is a unidirectional device (single avalanche diode for DC circuits where transients are always of one polarity). P6KE6.8CA is a bidirectional device (two back-to-back avalanche diodes for AC signal lines where transients can be positive or negative). For DC power rail protection, the P6KE6.8A (unidirectional) is the correct choice.

Previous：What is the peak pulse power rating of the P6KE6.8A under different waveform conditions?

Popular FAQs
What is the operating temperature range of P6KE120A?
2026-08-05
 -55C to +150C junction temperature for industrial and outdoor applications.
Can P6KE120A be used for 100V DC systems?
2026-08-05
Yes. The 102V stand-off voltage suits 100V-level DC rails with typical tolerances.
What is the peak pulse power of P6KE120A?
2026-08-05
600W for a 10/1000us exponential waveform at 25C.
