1.5KE300A ST Transient Voltage Suppressors (TVS)

The 1.5KE300A is a 1500W unidirectional Transil TVS diode from STMicroelectronics in DO-201 through-hole package, featuring 256V reverse standoff voltage and 300V typical breakdown voltage for high-voltage DC circuit 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 high-voltage applications, planar technology for high reliability, and excellent clamping capability. Ideal for voltage spike protection in high-voltage DC power supplies, industrial control equipment, telecom rectifiers, solar inverter DC input, and any 256V nominal high-voltage DC circuit requiring 1500W unidirectional transient suppression for protecting sensitive electronics against voltage transients.
