Transient protection for 60 V rails
The SMBJ60CA-13-F: This means a 60 V supply bus hit by a 6.2 A surge sees the voltage held under 97 V — enough to protect downstream ICs rated for 100 V abs-max.
Package and board integration
Housed in the DO-214AA (SMB) package, this is a surface-mount device with a small footprint suited for dense PCB layouts. The bidirectional configuration means a single device protects both positive and negative transients on the same line — useful for AC-coupled or floating signal pairs where polarity is not fixed.
