Product Summary

The KP2500A/2500V is a Transient Voltage Suppressor (TVS) designed for applications requiring protection of voltage-sensitive electronic devices that may be damaged by harsh or severe voltage transients including lightning per IEC61000-4-5 and class levels with various source impedances described herein. The KP2500A/2500V is available in 33 to 400 volt standoff voltages (VWM) in both unidirectional and bi-directional with either 5% or 10% tolerances of the Breakdown Voltage (VBR). Microsemi also offers numerous other TVS products to meet higher or lower power demands and special applications. The KP2500A/2500V is ideal for: (1)Protection from switching transients and induced RF; (2)Protection from ESD, and EFT per IEC 61000-4-2 and IEC 61000-4-4; (3)Secondary lightning protection per IEC61000-4-5 with 42 Ohms source impedance; (4)Secondary lightning protection per IEC61000-4-5 with 12 Ohms source impedance; (5)Secondary lightning protection per IEC61000-4-5 with 2 Ohms source impedance.
