1.5KE39CA Description

Short technical summary and product information.

The 1.5KE39CA is a bidirectional Zener TVS diode from STMicroelectronics designed for general purpose transient voltage suppression. It provides a 33.3V reverse standoff voltage and a typical breakdown voltage of 37.1V. The device can clamp transients to 69.7V while handling a peak pulse current of 143A (8/20µs waveform) with a power rating of 1500W (1.5kW).

 

This TVS diode is not intended for power line protection and is suited for unidirectional and bidirectional configurations in low-voltage circuits. The device features a capacitance of 1200pF at 1MHz.

 

The 1.5KE39CA is offered in a DO-201AA (DO-27) axial-lead through-hole package, making it suitable for manual and automated assembly processes. The DO-201 package provides robust mechanical and thermal performance for reliable circuit protection.
