The 20KPA28A is a 20kW peak pulse power unidirectional TVS diode from Littelfuse, designed to protect sensitive electronic equipment from voltage transients. It features a clamping voltage of 48V at 420.8A peak pulse current (10/1000μs waveform) and a fast response time of less than 1ps. The device is glass passivated for reliability and housed in a P600 axial through-hole package.
Key electrical specifications include a steady state power dissipation of 8.0W, peak forward surge current of 400A, and an operating junction temperature range of -55°C to 175°C. The thermal resistance is 8.0°C/W junction to lead and 40°C/W junction to ambient.
This TVS diode is suitable for general purpose applications including I/O interface protection, VCC bus, telecom, computer, industrial, and consumer electronics. It is RoHS3 compliant, Pb-free, and halogen-free. The component is ideal for use in circuits requiring high surge protection in a compact axial leaded package.
