The 20KPA256A is a unidirectional TVS diode from Littelfuse Inc. designed to protect sensitive electronic equipment from voltage transients. It features a reverse standoff voltage of 256V and a breakdown voltage of 412V, with a clamping voltage of 412V at a peak pulse current of 49A. The device can dissipate up to 20kW of peak pulse power (10/1000μs waveform) and operates over a junction temperature range of -55°C to 175°C.
This through-hole component is housed in a P600 axial package, suitable for high-reliability applications. It is designed for general-purpose transient voltage suppression, including protection of I/O interfaces, VCC buses, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The fast response time (typically less than 1.0ps) ensures rapid clamping of transient events.
