1.5KE56A ST Transient Voltage Suppressors (TVS)

The 1.5KE56A is a 1500W unidirectional Transil TVS diode from STMicroelectronics in DO-201 through-hole package, featuring 47.8V reverse standoff voltage and 56V typical breakdown voltage for 48V system 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 48V DC power systems, automotive electronics (48V mild hybrid systems), industrial power supplies, battery management systems, and any 47.8V nominal DC circuit requiring 1500W unidirectional transient suppression for protecting sensitive electronics in 48V distribution systems.
