Overview
The 1.5KE120A is a Transil™ diode produced by STMicroelectronics, designed to provide high overvoltage protection for sensitive electronic equipment. This unidirectional Transient Voltage Suppressor (TVS) diode is part of the 1.5KE series, which offers a range of breakdown voltages to suit various protection needs.
The 1.5KE120A is specifically rated for a breakdown voltage of 120 V, making it suitable for applications requiring protection against transient overvoltages. It is packaged in a DO-201-2 case and is available in both unidirectional and bidirectional configurations, though the 1.5KE120A is unidirectional.
