The SMAJ54CA-E3/61 is an Electronic Part manufactured by Vishay which features Transient Voltage Suppressors (TVS) Diodes with a 400W rating of 54V with 5% Bi-Directional Breakdown Voltage. It is an ideal device to provide surge and ESD protection for circuits subject to electrostatic discharge, switching transients, and other high peak transient energy. This TVS Diode is designed to protect components such as Input & Output devices, such as I/O Ports, TV Tuners, LEDs, USB Controllers, and RS-232 Interfaces. It is also an excellent solution for protecting RF switches and RF ports against broadband noise and over-voltage transients. The SMAJ54CA-E3/61 is a lead free, RoHS compliant device with high peak power handling capability, low leakage current, and fast response time.
