What are the key features of P6KE150CA?
- 600 W peak pulse power with bidirectional clamping for AC and bipolar rail transient protection
- 150 V nominal breakdown voltage with ±5% tolerance (143 V to 158 V) ensuring tight clamp thresholds
- 200 pF minimum junction capacitance — half that of unidirectional P6KE150A — for improved AC signal fidelity
- UL recognized DO-15 axial through-hole package suitable for safety-rated industrial and commercial designs
What is P6KE150CA used for?
The P6KE150CA is ideal for protecting AC power line interfaces, bridge rectifier inputs, and industrial automation equipment where voltage transients can strike in either polarity. Its bidirectional 150 V breakdown and 265 V clamping voltage make it effective in 120 V AC mains-connected circuits, variable-speed motor drives, and telecom line cards exposed to lightning and switching surges. The lower 200 pF capacitance compared to the unidirectional variant makes it preferable in AC-coupled protection stages where signal bandwidth matters.

Frequently Asked Questions
How does the P6KE150CA's bidirectional design protect 120 V AC mains interfaces from transient surges?
The P6KE150CA clamps voltage spikes in both polarities to a maximum of 265 V, making it effective on 120 V AC mains circuits where lightning and switching transients can be positive or negative. Its 600 W peak pulse power rating absorbs the transient energy during 10/1000 µs waveforms without requiring separate devices for each polarity.
What junction capacitance does the P6KE150CA have, and how does it compare to the unidirectional P6KE150A?
The P6KE150CA has a minimum junction capacitance of 200 pF, which is half the 400 pF of the unidirectional P6KE150A. This lower capacitance reduces signal distortion in AC-coupled protection stages, making the P6KE150CA preferable in frequency-sensitive applications such as industrial communication bus protection at 150 V signal levels.
What breakdown voltage range does the P6KE150CA provide, and why is the ±5% tolerance important for system design?
The P6KE150CA offers a breakdown voltage range of 143 V minimum to 158 V maximum, representing ±5% around the 150 V nominal. This 15 V tolerance band allows designers to guarantee that the device will not conduct during normal 120 V to 130 V DC operation while reliably clamping any transient that exceeds 143 V, with a maximum clamping voltage of 265 V.
When is the P6KE150CA a better choice than a Metal Oxide Varistor for 120 V AC surge protection?
The P6KE150CA offers faster response time (sub-picosecond versus tens of nanoseconds for MOVs) and tighter clamping voltage of 265 V maximum compared to MOVs which can clamp at higher voltages with significant variation. For circuits where precise 265 V clamping and consistent bipolar protection at 150 V breakdown are required, the P6KE150CA provides more predictable performance than MOVs of similar energy rating.
Can the P6KE150CA be used in automotive alternator protection circuits operating at 14 V nominal with load dump spikes reaching 150 V?
The P6KE150CA is not recommended for 14 V automotive systems because its 143 V minimum breakdown voltage is far above the 14 V operating rail and load dump spikes in automotive systems typically reach 60 V to 80 V peak, which would not reach the P6KE150CA's clamping threshold. A lower-voltage TVS in the P6KE series, such as P6KE36CA or P6KE68CA, would be appropriate for 14 V automotive load dump protection at 36 V or 68 V breakdown.
