Automotive-grade transient protection in a through-hole package
The 1.5KE130AHB0G is a 1500W peak-pulse-power Zener TVS diode from Taiwan Semiconductor's 1.5KE series, designed to clamp transients on 111V nominal rails in automotive and industrial power systems. The DO-201AA axial-lead package (also known as DO-27) is a standard through-hole form factor that mates with existing PCB layouts for 1.5KE-family parts, simplifying a drop-in replacement or BOM consolidation.
Clamping voltage and breakdown margins for 111V rails
Maximum clamping is 179V at the 8.7A peak pulse current (10/1000 µs waveform), which is the voltage the protected circuitry must survive without damage — a downstream MOSFET rated for 200V drain-source has margin here.
