What the voltage ratings mean for surge protection
The 5KP170CA-TP sits in the 5KP series — Micro Commercial Co's 5000W peak-pulse Zener TVS family in the R-6 axial package. The gap between standoff and clamping is the protection margin — the clamp ceiling of 275V is what the downstream circuitry sees during a transient event.
Thermal and environmental fit
The single bidirectional channel handles symmetric transient events — both polarities clamp to the same ceiling.
Packaging and board integration
The R-6 axial leadform mounts through-hole — the standard footprint for legacy power-supply and protection boards where a glass-bodied TVS with established land-pattern is preferred over a surface-mount part. Tape & Reel and cut-tape packaging serve both automated assembly and repair-stocking workflows. The lead pitch and body diameter are consistent with the MIL-PRF-19500 signal-gate Zener heritage of this package style.
Active status and sourcing posture
The 5KP series remains a current family line.
