Protection envelope for a 24 V rail
The SMBJ24CA-13: Its 24 V reverse standoff voltage sits below the rail's normal operating level, so it does not conduct during steady-state. The breakdown triggers at 26.7 V minimum, and the clamp voltage peaks at 38.9 V at the rated 15.4 A peak pulse current — a tight enough window to protect downstream 40 V-rated silicon.
Pulse power and junction temperature
The -55 to +150 °C operating range covers the full industrial temperature band and most under-hood automotive environments, though the part carries a General Purpose application designation — not AEC-Q101 qualified, so it is not formally released for automotive PPAP.
The single bidirectional channel protects one signal pair or power rail against both positive and negative transients, eliminating the need for two unidirectional devices in series.
