The SMAJ54CA-13-F is an ESD Suppressors / TVS Diodes 400W 54V manufactured by Diodes Incorporated. It is a surface-mount, unidirectional, single-line protector designed to protect sensitive electronic circuits from transient voltage events. It is a highly reliable, fast-acting protective device that will absorb very high surge currents and meet the surge requirements of ESD, lightning and other transient protection standards. The device has a maximum standoff voltage of 54V and a maximum peak pulse surge current of 400A. Its low leakage current ensures that the device does not have a negative effect on the circuit. It is suitable for use in a variety of applications, such as mobile phones, computers, consumer electronics, and automotive electronics.
