170V standoff TVS in a field-service friendly package
The 5KP170A_R2_00001 is a unidirectional Zener-based TVS (transient voltage suppressor) rated 170V reverse standoff with a 5 kW peak pulse capability — that 5 kW is the figure that decides whether it survives a load-dump or switching surge on a 170V DC rail without cascading upstream. The P600 axial through-hole body ships on tape-and-reel or cut tape, so it is straightforward to hand-solder or replace in the field without a hot-air station — the lead-form is obvious and polarity marking is on the body stripe.
Temperature margin for industrial and power environments
General-purpose classification means it is not pre-qualified to automotive AEC-Q101 or a specific safety standard — confirm against your system's EMI/ESD compliance matrix before committing to a safety-critical role.
Active sourcing posture and BOM fit
Listed Active with Panjit International Inc. — no NRND flag or documented end-of-life notice in the current record. The 5KP170 base product number sits in the middle of the series voltage spread — for a 170V rail the 5KP170A lands close to the nominal standoff, with adequate margin above it. If the board calls for a different standoff voltage, the series mates by base number.
