The SMCJ33A-13-F: It clamps a 33 V nominal rail at 53.3 V maximum, handling a peak pulse current of 28.1 A before the junction temperature hits the 150 °C ceiling. The 36.7 V minimum breakdown voltage gives a guard band above the 33 V reverse standoff — the diode stays off during normal operation and only conducts when a transient pushes the line past that threshold.
Housed in the DO-214AB (SMC) package, the device is rated for surface-mount assembly and occupies the same footprint as other SMC-packaged TVS diodes. The -13-F suffix denotes Tape & Reel packaging, suited for automated pick-and-place.
Sourcing and compliance
The base product number is SMCJ33; the -13-F variant is the Tape & Reel option. General-purpose application rating means no dedicated power-line protection features — it is a standard TVS for signal and low-power rail clamping.
