The SMBJ30CA is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD).
Key electrical specifications include a standoff voltage of 30 V, a clamping voltage of 48.4 V at a peak pulse current of 12.4 A, and a peak pulse power dissipation of 600 W. The device is bidirectional, making it suitable for applications where the signal lines can swing both positive and negative relative to ground.
The SMBJ30CA is housed in a DO-214AA (SMB) surface mount package, which is compatible with standard pick-and-place assembly processes. It operates over a junction temperature range of -65°C to 150°C. The part is intended for general purpose transient protection and is RoHS3 compliant (unverified).
