The CA suffix marks it as bidirectional, so it clamps both positive and negative overvoltage events without a second part. The 33V reverse standoff is the working voltage the diode tolerates continuously without conduction. The 36.7V minimum breakdown marks where it begins conducting during a transient. 1500W peak pulse power is the transient energy rating for this waveform class. The 28.1A peak pulse current is what the diode sinks at that clamping level — the two specs are linked by the clamping voltage, and both must fall within the device's peak-pulse rating curve. ## What this part does not cover Listed as general-purpose with no power-line protection rating — do not specify this for primary AC mains protection without a full fault-current and clearing-time analysis against the applicable standard. It is sized for secondary protection on low-voltage rails, signal lines, and local bus nodes, not for direct AC line-to-neutral clamping at the service entrance.","metaTitle":"1.5SMCJ33CA_R1_00001 TVS Diode, 33V Standoff, SMC","metaDescription":"Panjit 1.5SMCJ33CA bidirectional TVS diode, 33V standoff, 1500W peak pulse, DO-214AB SMC package.
