130V standoff — what the headline ratings mean
The 1.5SMCJ130CA_R1_00001 is a unidirectional Zener-based TVS diode rated 130V reverse standoff — the working voltage the circuit sees in normal operation — with a 1500W peak pulse power capability. Standoff voltage is the selection anchor: it sets the operating DC rail the protected node can sit at without the TVS drawing significant leakage current. The 7.2A rating corresponds to the 10/1000 µs wave shape standard for TVS diodes — the figure to compare against your upstream source impedance and the protected IC's abs-max input rating.
Thermal margin and bidirectional polarity
Bidirectional polarity means it clamps both polarities of surge — a single device handles symmetrical protection without a bridge configuration. The Zener type means the clamping characteristic is a hard avalanche knee, giving a defined let-through ceiling at the specified 7.2A peak current.
Sourcing — active production, standard SMC packaging
Panjit International Inc. marks this part Active in production — it is a current-line SMC (DO-214AB) package TVS diode sourced through independent distribution and quoted to order against BOM quantity. Tape-and-reel and cut-tape options are standard, covering both high-volume SMT placement and low-quantity prototype hand-assembly.
