1.5KE24CA 24V 1.5KE Series TVS Diodes 1500W DO-201 Transient Voltage Suppressors HORNBY

The 1.5KE Series is a high-power family of 1500 W TVS diodes designed to protect low-, medium-, and high-voltage power rails, industrial equipment, communication lines, automotive modules, and general-purpose electronics from severe transient surges.

Available in unidirectional (A) and bidirectional (CA) versions, the series delivers strong avalanche clamping performance during lightning surge pulses, inductive switching spikes, ESD/EFT bursts, and other high-energy disturbances.
Its rugged DO-201 glass-passivated axial package ensures exceptional surge endurance, stable electrical characteristics, and long-term reliability in harsh industrial and commercial environments.
