STMicroelectronics 1.5KE Series Bidirectional TVS Diode 20.5V 33.2V Axial Lead

The STMicroelectronics 1.5KE Series Bidirectional TVS Diode is a high-performance transient voltage suppressor, engineered to provide robust protection for sensitive electronic circuits. These diodes offer immediate, high-power overvoltage protection by utilising a fast-acting clamping mechanism, safeguarding components from damaging voltage spikes and transients. The bidirectional variant is specifically designed for alternating current (AC) applications, making it a versatile solution for a wide range of electrical environments.

With a formidable peak pulse power dissipation of 1.5kW, this TVS diode can handle significant surge events. It features an extremely fast response time and a high surge capability, ensuring sensitive devices are protected almost instantaneously. Its low clamping factor is critical, as it limits the voltage let-through to a safe level, well below the maximum clamping voltage of 33.2V, based on a reverse standoff voltage of 20.5V.
