1.5KE47A ST Transient Voltage Suppressors (TVS)
The 1.5KE47A is a 1500W unidirectional Transil TVS diode from STMicroelectronics in DO-201 through-hole package, featuring 40.2V reverse standoff voltage and 47V typical breakdown voltage for 48V system protection. For selection, verify peak pulse power of 1500W for 10/1000µs waveform, low clamping factor for effective voltage clamping, fast response time, UL recognized, and operating temperature from -55°C to +175°C. Features include unidirectional configuration for DC applications, planar technology for high reliability, and excellent clamping capability. Ideal for voltage spike protection in 48V automotive systems, industrial power supplies, battery management systems, communication equipment, and any 40V nominal circuit requiring 1500W unidirectional transient suppression for protecting sensitive electronics in 48V distribution systems.
