500W bidirectional Zener TVS for harsh-environment rail clamping
It clamps transients on a 5.7V nominal rail to 11.2V maximum, handling 44.6A peak pulse current. The single bidirectional channel protects AC or bipolar signal lines without back-to-back series diodes. The axial through-hole package (B, Axial) is a standard footprint for point-to-point wiring or PCB through-hole mounting.
Breakdown and clamping margins for a 5V rail
Minimum breakdown voltage is 7.13V, giving a 1.43V guard band above the 5.7V standoff. The 11.2V clamp at 44.6A limits let-through to 1.96× the standoff — tight enough for 5V CMOS logic without secondary protection. Power line protection is not listed (Power Line Protection: No), so this part is intended for signal or low-power supply lines rather than mains or high-current bus clamping.
Active production — no LTB pressure on this BOM line
Microchip Technology lists the 1N6103A as Active. The base product number is 1N6103, and the 1N6103A suffix indicates a specific breakdown tolerance bin. Package is — typical for through-hole axial diodes.
