1.5KE43A Description

Short technical summary and product information.

The 1.5KE43A is a unidirectional transient voltage suppression (TVS) diode designed for general purpose circuit protection. It offers a peak pulse power dissipation of 1500W for a 10/1000µs waveform, ensuring robust protection against voltage transients. The device has a nominal breakdown voltage of 43.1V with a clamping voltage of 59.3V at 26A peak pulse current.

 

This TVS diode features a fast response time of less than 1.0 ps and is capable of handling high surge currents. It is housed in a DO-201AA/DO-27 axial lead package suitable for through-hole mounting. The operating temperature range spans from -55°C to 175°C, making it suitable for demanding environments.

 

Typical applications include protection of I/O interfaces, VCC bus lines, and other vulnerable circuits in telecom, industrial, and consumer electronics. The device is lead-free and halogen-free, compliant with RoHS and REACH standards.
