STMicroelectronics TVS Diode Uni-Directional 2-Pin DO-201 1.5 kW Peak Pulse Power 1.5KE68A

STMicroelectronics 1.5KE68A is a uni-directional transient voltage suppressor (TVS) diode designed for protecting sensitive electronic circuits from voltage spikes. This single element diode features a peak pulse power dissipation capacity of 1.5 kW, making it suitable for high transient voltage and surge absorption.

Encapsulated in a compact DO-201 axial through-hole package measuring 9.5 mm length and 5.3 mm diameter, this diode supports integration into various printed circuit boards requiring component-level protection. The minimum breakdown voltage of 64.6 V and a maximum reverse stand-off voltage of 58 V enable precise clamp activation to prevent damage.

With thermal operational limits ranging from -65°C up to 175°C, the 1.5KE68A diode is reliable across broad industrial and commercial environments, including power supplies, automotive electronics, and general industrial applications. The device's maximum peak pulse current capability of 83 A ensures resilience against large transient surges.

The diode provides low reverse leakage current (1 μA) to maintain energy efficiency and minimize unwanted leakage during normal operation. Although not qualified to automotive standards, it offers robust protection for general semiconductor applications.

Its unidirectional design offers selective voltage spike suppression in one polarity direction ideal for DC-powered electronic circuits. The 2-pin configuration and through-hole mounting style facilitate easy assembly and secure connections.
