SMBJ250A Description

Short technical summary and product information.

The Littelfuse SMBJ250A is a 600W surface mount TVS diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It is part of the SMBJ series and features a unidirectional polarity.

 

Key electrical specifications include a reverse standoff voltage of 250V, a clamping voltage of 405V at a peak pulse current of 1.5A per the 10/1000µs waveform, and a peak pulse power dissipation of 600W. The device offers a fast response time of less than 1 picosecond and a typical reverse leakage current of less than 1µA for breakdown voltages above 12V. It also provides ESD immunity of 30kV (air and contact) per IEC 61000-4-2.

 

The SMBJ250A is housed in a DO-214AA (SMB) surface mount package and has an operating temperature range of -65°C to 150°C. It is suitable for general purpose applications, including I/O interface protection, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic systems.
