Clamping voltage and surge rating
The P6KE130CA-T: The 179 V clamp means a 111 V bus sees the spike limited to that level — the downstream DC-DC converter's input FET must survive the clamp voltage plus any board inductance overshoot. The 600 W rating is the peak pulse power the device can absorb in a single transient; it is not a continuous dissipation figure.
Package and temperature envelope
Housed in a DO-204AC (DO-15) axial-lead through-hole package, the P6KE130CA-T mounts into a standard 0.025-inch diameter plated through-hole. The junction temperature range spans -55°C to 175°C, covering industrial and some automotive under-hood environments. The bidirectional configuration means it clamps both polarities with a single device — useful on AC-coupled data lines or floating DC buses where the transient polarity is unknown.
Diodes Incorporated lists the P6KE130CA-T as obsolete.
