1.5KE120A ST Transient Voltage Suppressors (TVS)

The 1.5KE120A is a 1500W unidirectional Transil TVS diode from STMicroelectronics in DO-201 through-hole package, featuring 102V reverse standoff voltage and 120V typical breakdown voltage for 100V system transient 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 circuit protection, planar technology for high reliability, and compliance with IEC 61000-4-2/4-4/4-5 standards. Ideal for voltage spike protection in 100V DC power systems, industrial power supplies, communication equipment, solar inverter DC input protection, and any 102V nominal circuit requiring 1500W unidirectional transient suppression for protecting sensitive electronics against lightning-induced surges and switching transients.
