1.5KE440A ST Transient Voltage Suppressors (TVS)

The 1.5KE440A is a 1500W unidirectional Transil TVS diode from STMicroelectronics in DO-201 through-hole package, featuring 376V reverse standoff voltage and 440V typical breakdown voltage for high-voltage AC rectified circuit protection. For selection, verify peak pulse power of 1500W for 10/1000µs waveform, low clamping factor, fast response time, UL recognized, and operating temperature from -55°C to +175°C. Features include unidirectional configuration for DC high-voltage applications, planar technology for high reliability, and excellent clamping capability. Ideal for voltage spike protection in high-voltage DC power supplies (380V DC buses), three-phase rectified circuits, industrial equipment, solar inverter DC input, and any 376V nominal high-voltage DC circuit requiring 1500W unidirectional transient suppression for protecting sensitive electronics in high-voltage power distribution systems.
