1500W transient suppressor for 160V rails
The SMCJ160A-13-F: Breakdown occurs at 178V minimum, providing a tight 18V window between standoff and clamp — the protection engages before most downstream silicon sees damaging voltage. Packaged in the DO-214AB (SMC) surface-mount body, it handles the 5.8A peak pulse current without the package cracking — the SMC footprint is the standard for 1500W TVS diodes in this voltage class.
Where the 1500W rating matters
A 1500W TVS absorbs a single surge of that energy; repeated surges require derating per the pulse derating curve. The -55°C to 150°C junction temperature range covers outdoor enclosures and hot power supplies — the TVS does not derate significantly until ambient exceeds 25°C, but above that the peak pulse power must be reduced per the datasheet curve.
