SMCJ24A
by Littelfuse(美国力特)Transient protection is the role of Littelfuse's SMCJ24A, a unidirectional TVS diode in an SMC surface-mount package. It is used across a protected line to clamp voltage excursions during transient events. Because the device is unidirectional, anode and cathode orientation matters in both the circuit and the layout. For KiCad, the free verified download supplies a 2-pin symbol and the SMC_L6.9-W5.9-LS7.9-RD footprint with 2 pads, plus a 3D model. A total of 1 ProtoFlow engineer has used this conversion in real designs. The complete part is also available to open directly in ProtoFlow.
