Product details

The 5KP18A-TP: The 5000 W peak pulse rating defines the surge energy this Zener TVS absorbs without degradation — a transients on an industrial 24 V bus that peaks at 29.2 V gets clamped hard before it reaches downstream circuitry. The 18 V reverse standoff sets the maximum working voltage the device holds off during normal operation before conduction begins. Junction temperature runs to 175 °C maximum, so thermal headroom under pulsed load is real — a derated board thermal pad or generous spacing keeps the TJ well below that ceiling during the transient event.

R-6 axial package for through-hole assembly

The R-6 axial package with through-hole mounting is the classic leaded TVS form factor — it drops into a 0.400-inch lead spacing footprint on a PCB without any special tooling. The leaded format conducts heat away from the junction during a surge event more effectively than a surface-mount part of comparable rating. Tape & Reel and Cut Tape packaging covers both automated insertion for volume production runs and single-unit bench use.

Frequently asked questions

What type of protection does the 5KP18A-TP provide?

It is a unidirectional Zener TVS diode — the 18 V standoff means it blocks normal operating voltage and the 29.2 V clamping ceiling clamps transient spikes at a safe level for downstream components. This class is deployed on power buses and signal lines in industrial and instrumentation equipment where voltage transients are a known hazard.
