Product details

1500W bidirectional TransZorb — protection thresholds

The 1.5KE300C-E3/54: This clamping threshold means the diode limits transients to 430V — critical for protecting downstream semiconductors rated below that ceiling.

Through-hole DO-201AA axial package

Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE300C-/54 is a through-hole component. The axial form factor suits point-to-point wiring, terminal block mounting, or PCB through-hole layouts where a surface-mount TVS is not preferred.
