SMBJ48A Description

Short technical summary and product information.

The SMBJ48A is a 600W transient voltage suppression (TVS) diode from Littelfuse Inc., designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It has a reverse standoff voltage of 48V and a clamping voltage of 77.4V at a peak pulse current of 7.8A.

 

Electrical specifications include a minimum breakdown voltage of 53.3V and maximum of 58.9V. The device is unidirectional with one channel and uses Zener technology. It offers excellent clamping capability and low incremental surge resistance. Typical leakage current is less than 1μA for breakdown voltages above 12V.

 

The SMBJ48A is housed in a DO-214AA (SMB) surface mount package and operates over a temperature range of -65°C to 150°C. It is RoHS compliant and halogen free per the manufacturer's specifications, though compliance data is unverified.

 

Additional features from the SMBJ series datasheet include IEC-61000-4-2 ESD protection up to 30kV (air and contact), fast response time typically less than 1.0ps, and UL recognition for data communications and fire-alarm circuits. The component is suitable for general purpose applications such as I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.
