The SA28 is a 500W unidirectional TVS diode designed to protect sensitive electronic equipment from voltage transients. It is part of Littelfuse's SA series, featuring a glass passivated chip junction in a DO-15 package. The device offers a peak pulse power dissipation of 500W at 10/1000μs waveform, with a clamping voltage of 47.67V at 11.2A. It has a fast response time of less than 1.0ps from 0V to breakdown voltage minimum. The SA28 is suitable for general purpose applications such as I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. It is through-hole mounted with axial leads, operating over a temperature range of -55°C to 175°C. The device is halogen free, RoHS compliant, and has a matte tin lead-free finish.
The clamping voltage is 47.67V at 11.2A (10/1000μs waveform).
The peak pulse current is 11.2A at 10/1000μs waveform.
The SA28 is available in a DO-204AC (DO-15) axial leaded package.
The peak pulse power dissipation is 500W at 10/1000μs waveform.
The operating temperature range is -55°C to 175°C.
Yes, it is listed as RoHS3 compliant, but this is unverified.
