The SMBJ54A is a unidirectional TVS diode from Littelfuse designed to protect sensitive electronic circuits from voltage transients. It features a reverse standoff voltage of 54V and a clamping voltage of 87.1V. With a peak pulse power rating of 600W (10/1000µs waveform), it can handle peak pulse currents up to 6.9A.
This device offers fast response time (<1 ps from 0V to VBR min) and built-in protection against ESD (30kV air/contact per IEC 61000-4-2) and EFT (IEC 61000-4-4). It is UL recognized to ANSI/UL 497B for data communication and fire-alarm circuits. The package is DO-214AA (SMB) for surface mount applications, with matte tin lead-free plating.
The SMBJ54A operates over a temperature range of -65°C to 150°C (junction) and has a storage temperature range of -65°C to 175°C. It is halogen-free and RoHS compliant, with a flammability rating of V-0. Typical applications include I/O interfaces, VCC bus protection, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
