600W Zener TVS for single-line clamping
The P6KE15A-T: It clamps a 12.8V reverse standoff voltage to 21.2V maximum at 28A peak pulse current, protecting a single line in general-purpose circuit protection applications.
Breakdown and clamping thresholds
Minimum breakdown voltage is 14.3V, ensuring the device starts conducting before the protected rail exceeds that level. The 12.8V reverse standoff voltage means the TVS draws negligible leakage below this threshold — it sits on the line without loading the signal during normal operation. Maximum clamping voltage of 21.2V at 28A peak pulse current defines the worst-case voltage the downstream circuitry sees during a transient. For a 12V nominal rail, this clamp gives roughly 9V of headroom above the operating voltage before the protected components must withstand the spike.
DO-15 axial package and board integration
Housed in a DO-204AC (DO-15) axial-lead package, the P6KE15A-T mounts through hole. The axial body and lead spacing suit point-to-point wiring or PCB through-hole layouts common in power supply inputs, telecom line cards, and industrial control boards where a soldered connection is preferred over surface-mount.
Temperature range and operating envelope
The wide junction temperature margin means derating for high ambient or self-heating during repetitive pulses is less aggressive than on a 150°C-rated part.
