Clamping voltage and pulse current — the protection window
The 1.5KE120AHE3_A/C: Above that, breakdown begins at 114 V min, and clamping is guaranteed at 165 V max when the 9.1 A peak pulse current flows. This 165 V clamp ceiling means downstream components rated for 200 V or higher see a safe voltage during a surge — a common design margin for automotive ECU power stages and sensor inputs. At 175°C the leakage current rises but the clamping characteristic remains within spec — no derating required for the pulse power at high temperature.
Through-hole axial package and board integration
Housed in the DO-201AA (DO-27) axial-lead package, the 1.5KE120AHE3_A/C mounts through-hole. The 1.5KE body diameter and lead spacing match standard 0.100-inch pitch PCB layouts or terminal block wiring — common in automotive relay boxes and power distribution centers. Tape-and-reel packaging suits automated insertion for volume production. The axial leads handle board flex and vibration better than SMD packages in high-shock environments.
Active production and sourcing posture
Sourced through authorized distribution channels. Tape-and-reel quantities are the standard supply format.
