What the 1.5SMCJ200CA_R1_00001 is and where it sits
At that rating this part clamps a 4.6 A surge current to 324 V without shifting into thermal runaway.
What the clamping window means for the circuit
The 220 V minimum breakdown floor means the device stays off and transparent on a 200 V rail — it does not leak or clamp until a transient exceeds the standoff. The clamping voltage of 324 V at peak pulse current is the let-through maximum the protected load must withstand. For a TVS protecting a power rail, the 150°C Tj ceiling sets the allowable surge energy budget before the thermal resistance junction-to-ambient derating curve cuts into the rated peak pulse power. If the end equipment requires automotive-grade TVS, confirm the Panjit automotive line has an AEC-Q101 qualified equivalent before committing to the BOM.
SMC package and board assembly fit
The DO-214AB (SMC) is a industry-standard surface-mount outline — the two-tab Gull Wing terminations land on a standard IPC footprint. Tape-and-Reel packaging is compatible with standard SMT pick-and-place lines. Confirm the recommended pad geometry in the Panjit datasheet before releasing to layout — the tab attach area governs the RthJC and the effective surge-withstand capability.
