The 15KPA40CA is a bidirectional Zener-type TVS diode from Littelfuse's 15KPA series, designed to protect sensitive electronic equipment from voltage transients caused by lightning and other surge events. It features a reverse standoff voltage of 40V and a clamping voltage of 65.8V at a peak pulse current of 229.5A.
The device delivers 15kW peak pulse power (10/1000μs waveform) and has a steady state power dissipation of 8.0W. It is housed in an axial-leaded P600 through-hole package and operates over a junction temperature range of -55°C to 175°C. The part is lead-free (matte tin plating), halogen-free, and RoHS3 compliant with MSL 1 (unlimited).
Typical applications include general purpose transient voltage suppression for I/O interfaces, VCC buses, telecom, computer, industrial, and consumer electronics. The diode offers fast response time (typically less than 1.0ps from 0V to breakdown voltage) and low incremental surge resistance.
The reverse standoff voltage (VR) is 40V.
The clamping voltage (VC) is 65.8V at the peak pulse current of 229.5A.
