600 W bidirectional transient suppressor for 160 V rails
The SMBJ160CA-13: Bidirectional construction means a single device protects both polarities on the line — useful for AC signal lines or DC rails where reverse-voltage events are possible. The 160 V reverse standoff voltage (working voltage) sits below the rail's normal operating level so the diode stays transparent until a surge arrives.
Housed in the DO-214AA (SMB) surface-mount package, the SMBJ160CA-13 occupies a standard footprint shared across the SMBJ series. The wide range means the clamping voltage stays within spec across the full temperature band — no thermal runaway risk on a hot PCB near a power stage.
Active production — no lifecycle concern
No second-source or cross-reference is recorded — the SMBJ series footprint is standard enough that a parametric match from another brand would require verifying the clamping voltage and pulse current ratings against the same 10/1000 µs waveform.
