SP0503BAHTG
by Littelfuse(美国力特)
Littelfuse’s SP0503BAHTG is a transient-voltage-suppression diode array used to protect signal lines from electrostatic-discharge events. Its four-pin arrangement suits designs that need several protected connections in one small surface-mount device, including exposed interfaces and control lines. The downloadable KiCad package supplies a four-pin symbol, the SOT-143_L2.9-W1.3-P1.92-LS2.3-BR footprint with four pads, and an included 3D model for board and enclosure checks. The conversion has already been used by 2 ProtoFlow engineers in real designs, confirming the imported part through practical editor use. It is ready to open directly in ProtoFlow.
