1.5KE30A Description

Short technical summary and product information.

The 1.5KE30A is a unidirectional TVS diode from STMicroelectronics designed for general purpose transient voltage suppression. It features a reverse standoff voltage of 25.6V and a clamping voltage of 53.5V, providing robust protection against voltage spikes.

 

With a peak pulse power rating of 1500W (1.5kW) and a peak pulse current of 187A (8/20µs waveform), this device can handle high-energy transients. The capacitance is 2900pF at 1MHz, which is suitable for lower-speed signal lines.

 

The diode is housed in a DO-201AA / DO-27 axial leaded package, supporting through-hole mounting. It is RoHS3 compliant and has an MSL of 1 (unlimited). This part is intended for general purpose circuit protection applications where unidirectional clamping is required.
