1.5KE7V5CA

1.5KE7V5CA Description

The 1.5KE7V5CA from STMicroelectronics is a bidirectional Zener-type TVS (Transient Voltage Suppressor) diode designed for robust transient protection in general-purpose applications. Part of the 1.5KE, TRANSIL™ series, it offers a peak pulse power dissipation of 1500W (1.5kW) and a clamping voltage of 14.5V at 690A (8/20µs surge current), ensuring reliable suppression of high-energy transients. With a reverse standoff voltage of 6.4V and a minimum breakdown voltage of 7.13V, it provides precise voltage regulation and protection for sensitive circuits. The diode features low capacitance (4250pF @ 1MHz), minimizing signal distortion in high-frequency applications. Packaged in a DO-201 through-hole format, it is RoHS3 compliant and suitable for harsh environments.
