Clamping parameters and transient protection envelope
The SMCJ170CA-13-F: Reverse standoff voltage is 170V, meaning the TVS draws negligible leakage below this rail voltage. Breakdown occurs at a minimum of 189V, so a 170V nominal bus has margin before the device starts conducting.
Package and board integration
Housed in a DO-214AB (SMC) surface-mount package, the SMCJ170CA-13-F is intended for reflow soldering on standard PCB footprints. The SMC body handles the 1500W pulse without package cracking — the key is a low-inductance layout with short traces between the TVS and the protected node. The peak-pulse power derates above 25°C per the datasheet curve — at 125°C ambient, derate to roughly 60% of the 1500W rating.
Production status and procurement posture
The base product number SMCJ170 covers the family; the -13-F suffix denotes the tape-and-reel packaging variant. Sourced through independent distribution channels.
