1.5KE33A ST Transient Voltage Suppressors (TVS)
The 1.5KE33A is a 1500W unidirectional Transil TVS diode from STMicroelectronics in DO-201 through-hole package, featuring 28.2V reverse standoff voltage and 33V breakdown voltage for transient overvoltage protection. For selection, verify peak pulse power of 1500W for 10/1000µs waveform, low clamping factor for effective voltage clamping, fast response time for instantaneous clamping action, UL recognized, and operating temperature from -55°C to +175°C. Features include planar technology for high reliability, compliance with IEC 61000-4-2/4-4/4-5 standards, and breakdown voltage range from 6.8V to 440V. Ideal for voltage spike protection in 24V power systems, industrial power supplies, communication equipment, I/O interfaces, general purpose circuit protection, and any 28V nominal system requiring 1500W unidirectional transient suppression for protecting sensitive MOS technology and low voltage supplied ICs.
